After the bugs developed resistance against many of the most powerful pesticides, such as DDT, exterminators had been increasingly relying on two chemicals—chlorfenapyr and bifenthrin. But until now, no one had looked at whether bed bugs were developing defenses against these chemicals too, says Ameya D. Gondhalekar, one of the study authors and a research assistant professor at the Center for Urban and Industrial Pest Management at the Department of Entomology at Purdue University.

Dusts have been used to ward off insects from grain storage for centuries, including plant ash, lime, dolomite, certain types of soil, and diatomaceous earth or Kieselguhr.[60] Of these, diatomaceous earth in particular has seen a revival as a nontoxic (when in amorphous form) residual pesticide for bed bug abatement. While diatomaceous earth performed poorly, silica gel may be effective.[61][62]
Checking beds for bed bugs was a common practice long ago, especially while traveling. Travelers today should consider doing the same, preferably before unpacking. This would entail examining the bed sheets and seams of the mattress and perhaps box spring for signs of bed bugs, especially along the head (pillow end) of the bed. Experts also remove and check behind headboards since this is a frequent hiding place for bed bugs in hotels. Headboards are heavy and cumbersome, however, and untrained persons should not attempt removal themselves.

Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective.[3][6] An hour at a temperature of 45 °C (113 °F) or over, or two hours at less than −17 °C (1 °F) kills them.[6] This may include a domestic clothes drier for fabric or a commercial steamer. Bed bugs and their eggs will die on contact when exposed to surface temperatures above 180 °F (82 °C) and a steamer can reach well above 230 °F (110 °C).[31][15] A study found 100% mortality rates for bed bugs exposed to temperatures greater than 50 °C (122 °F) for more than 2 minutes. The study recommended maintaining temperatures of above 48 °C (118 °F) for more than 20 min to effectively kill all life stages of bed bugs, and because in practice treatment times of 6 to 8 hours are used to account for cracks and indoor clutter.[32] This method is expensive and has caused fires.[6][15] Starving them is not effective as they can survive without eating for 100 to 300 days, depending on temperature.[6] One expert recommends not trying to get rid of bed bugs exclusively on one's own.[29]
Some people have no reaction whatsoever to bed bugs. In addition to not having much of an effect on the elderly, some are just not allergic. Since the irritation and welting appears as the result of an allergic reaction, it is possible to not even know that you were bitten at all. It is entirely possible for several people to live in the same house, and have one person not be affected.
Bedbugs do, however, have a unique bite pattern. Although some bites may appear alone, most bites occur in a row of three to five bites (termed "breakfast, lunch, and dinner") or in a cluster of red bumps (a rash called bedbug dermatitis). The bites often appear in a zig-zag formation, but may appear in a straight line if the bugs bite you in the morning.
Mix 8 ml (about 1/3 oz)(measurements on the bottle) or one 8 ml vial of Temprid FX with one gallon of water. Remember to use what you mix-within 24 hours. Adjust the spray pattern to a mist by turning the nozzle. A low fine mist is best for most spraying, but you may need to use a stream to get into some cracks and crevices. If you can't get into the cracks and crevices use one of the aerosols described below with it's crack and crevice tips to reach into these areas.
Bed bugs feed exclusively at night. They take approximately three to five minutes to engorge on blood. Once feeding is complete, they return to their harborage. Feedings take place every few days and nymphs require approximately six blood meals for complete development. Humans are the preferred host for the common bed bug, but it will feed readily on other animals, such as poultry, mice, rats, canaries, dogs, and cats, when necessary. Normally the bugs feed at night, but they will feed during daylight hours in places such as theaters, offices, and rest rooms that are not ordinarily used at night.
Then it was a baby bed bug. They are super tiny. I hope you washed out your suit case and clothing. I just found her bugs in my home and we think it came from the museum my husband works at where 1000’s of people come day in and day out. Probably transported them from his back pack. It’s been a nightmare for two days now. I’ve had to throw away my curtains and the box spring. It’s just awful. The sprays and foggers are okay but bleach and peppermint oil seems to be working as well as the more expensive remedies.

Bedbug bites themselves are typically painless. However, the subsequent allergic reaction that may develop can cause intense pruritus. While feeding, bedbugs may inject one of several pharmacologically active substances, including hyaluronidase, proteases, and kinins. These compounds may induce different skin reactions, such as erythema, wheals, vesicles, or hemorrhagic nodules. Repeated bites may sensitize individuals, leading to more pronounced cutaneous manifestations or systemic hypersensitivity reactions. The local trauma from bedbug bites can lead to secondary bacterial infection, causing ecthyma, cellulitis, or lymphangitis. There is some evidence that bedbugs may also be a vector for hepatitis B and Chagas disease. Histologic findings from bite-site biopsy specimens typically show eosinophilic infiltrates, which are indicative of the allergic nature of the reaction. The image shown is papular urticaria, which may develop from bedbug bites.
Should I worry about a tick bite? Ticks are parasites that feed on blood, and although their bites are harmless they can still transmit diseases, such as Lyme disease or Rocky Mountain spotted fever. Learn what ticks are and how to recognize the signs and symptoms of a bite. This MNT Knowledge Center article also explains how to prevent tick bites. Read now
Insecticides might also have their work cut out for them: Entomologists have known that the common bedbug has built up resistance to some typical insecticides such as those containing certain pyrethroid chemicals like deltamethrin, according to Entomology Today. Deltamethrin apparently paralyzes an insect's nervous system, according to Cornell University.
“Good night, sleep tight, don’t let the bed bugs bite.” This horrific nighttime creature is a member of the Hemiptera order of insects that feast solely on blood. Because of the way they mate, they multiply in size while breeding. A Department of Health report claimed that if forty are placed in a room with a mild temperature, within six months their population would exceed 5,900.

If at all possible, pull up the carpet where it meets the wall and puff powder around the whole perimeter of the room. Inside outlet boxes is a great place to use powders because sprays and electricity don’t mix. Bellow dusters work great for spreading residual insecticide powder. An old makeup brush is a good tool to spread the dust around on hard surfaces. Bed bug powders are available the same places you’ll find the spray pesticides.

Hiring a pro to wipe out bed bugs isn’t cheap. Expect to pay about $200 per room to kill bed bugs, and you’ll likely need a few chemical treatments in order to eradicate bed bugs. Professional heat treatments will cost even more. And even if you hire a pro, you’ll still have to do lots of work yourself (moving furniture, washing all clothes, etc.). So consider declaring a DIY war on bed bugs. If you’re willing to spend $100 to $200 and do things right, your chances of success are excellent.
They also have the ability to travel beyond the bedroom, so all adjoining rooms should be checked for infestation. Any area that offers a layer of protection, e.g. dark, isolated areas, should be checked. They do leave excrement droppings behind, so even if they are not seen, you can often see where they have been. The best method to find them is to check only at night, and with a red light.
Perform a quick inspection of the upper piping every time you change your sheets. Make a more thorough examination by folding the piping over and closely inspecting both sides all the way around, top and bottom. Do this a couple times a year or every time you flip or rotate your mattress. If you spot any signs, keep reading to learn how to get rid of bed bugs.
Use precautions in your own home. Keep the plastic covering that comes on your mattress when purchased new. Purchase special bedbug covers for you mattress and box spring. Make sure that they are quality ones with heavy duty zippers and constructed with special fabric that doesn't rip easily. Don't buy the cheap versions which are not thick enough to prevent the bedbugs from sticking their feeding tubes into the skin through the cover.[19]
Bed bugs have a fast and large reproduction nature. On an average, they can reproduce within 200 to 250 eggs at one time, and hatch during an interval between 6 to 10 days. Bed bugs largely live between 4 months to 6 months, and a 1-time treatment is not sufficient to cover the Bed Bug life stages. A 3 times treatment integrated with steam treatment and follow ups across 1.5 to 2 months is usually recommended. Read more here on 6 Questions to Get the Best Treatment for Bed Bugs.
People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
Apply as a coarse, low-pressure spray to harborage areas including crevices, baseboards, loose plaster, behind bed frames and headboards, beneath beds and furniture, and to bedsprings and bed frames. After removal of bed linens, apply Transport Mikron to mattress and boxsprings. Apply to tufts, edges, seams and folds (do not spray clothes or bed linens). Your may apply it to furniture, but not to areas where there is direct access to seating or arm placements. Infested bed linens should not be treated, but should be removed, placed in sealed plastic bags, and taken for laundering and drying at high temperatures.
Bed bug infestations are primarily the result of two species of insects from genus Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] These insects feed exclusively on blood and may survive a year without eating.[3] Adult Cimex are light brown to reddish-brown, flat, oval, and have no hind wings. The front wings are vestigial and reduced to pad-like structures. Adults grow to 4–5 mm (0.16–0.20 in) long and 1.5–3 mm (0.059–0.118 in) wide.

Once Step 2B is complete and the insecticide mixture is dry, you can follow up with a bed bug aerosol spray. Bed bug aerosol sprays are insecticides that have fine particles that get deep into cracks and crevices. By using both a liquid concentrate insecticide mixture and an aerosol spray, you can treat bed bugs that may have built up a resistance to one product but not the other.
Low toxicity contact sprays like SteriFab™ or Bedlam® are likely to kill bed bugs only on contact. Alcohol- and soap-based sprays, are only partly effective. All of these products, once dry, are likely to provide no further control. Eggs will not be killed by alcohol-based sprays, so repeat treatments are usually needed. Be careful when using sprays containing alcohol because they may be flammable.
One trick to make this disposal easier involves using the cut-off end of a nylon stocking (or a knee-high nylon stocking) and a rubber band. Insert the stocking (toe first) into the end of the vacuum suction wand/tube, leaving the opening of the stocking protruding out of the end of the suction wand. Then fold the stocking opening back over the end of the wand and use the rubber band to secure it there. When the vacuum is turned on and the bed bugs are sucked into the tube, they will be trapped in the stocking. Afterwards, carefully remove the rubber band and retrieve the bug-filled stocking. Then secure the end of the stocking with the rubber band and dispose of it. 
As if you needed something else to worry about, bedbugs, those pests from the old bedtime rhyme are making a comeback. More of a nuisance than a health hazard, they’re showing up to suck blood from people in hotels, college dorms, and hospitals. Take an informative look at bedbugs: what they are, where they lurk, and how to spot them before they get you.
Other types of bed bug traps include those that do not rely on humans as bait, but instead use CO2and/or other attractants. CO2 is thus far the most powerful lure for bed bugs, as it is the primary cue they follow to locate hosts. Traps that issue CO2 for a period of time are more expensive than Climbup™ traps, but can effectively trap bed bugs when no host is present, such as in common areas, vacant homes or units, offices, schools, and theaters. Thus they can help confirm infestation and eradication.
The main reason people seem to favor the essential oil option is that it’s considered a natural and chemical-free alternative to pesticide sprays. What they don’t realize is that today’s home pesticides are carefully regulated by the EPA to make sure that they’re safe for indoor use. The EPA also requires that health and safety guidelines are included in the product label and MSDS, to ensure that anyone who uses a spray has instructions on how to use it safely and effectively. When used correctly, even our strongest bed bug sprays won’t have any effect on you, but they will kill bed bugs more effectively than any mixture of household items like herbs or oils.

Prepare the room by separating treated from untreated furniture.  This will involve moving all your furniture to one side of the infested room (Remember, you’ve already assessed which rooms you think are infested.  You may not need to do this in every room).  The process is important because if you treat half of the items in a room and leave other areas untreated, bed bugs may return to the previously treated areas from untreated sites. Take all clothes from drawers, infested closets, etc. and double bag them in clear plastic bags (clear bags are easier to see where things are). Also double bag all personal items (toys, papers, books, electronics, CDs, or anything that could serve as a hiding place for bed bugs) and set them aside until they can be carefully treated, cleaned or inspected. 
The only problem with Dee is that it is not safe if inhaled, the ground up po wder feels silky smooth but it is not, it is very jagged, this can only be seen under a magnified lens. (That is how it kills the bugs) it tears open their abdomen) With that being said the results of inhalation for humans as well as pets can be painful & expensive to cure. It causes respratory infection, as well as many other respratory issues, & can also lead to cancer. It is however very effective for the job.
Systematically examine and treat all furniture (beds, bed frames, dressers, chairs, couches, night stands, etc.) following the same procedures and recommendations above. As a piece is treated it can be returned to the parts of the room that have been treated.  Note that furniture should be taken apart, drawers and cushions removed in order to inspect and treat every nook and cranny. When treating upholstered furniture, pay attention to each welt, button and fold. You may wish to discard low-value, stuffed furniture that is infested and too difficult to treat.  After spraying, return each article of furniture to the part of the room that has been treated. Do not reintroduce any furniture or other items to the treated room until they have been thoroughly cleaned, inspected or treated.
Cracks and crevices of bed frames should also be examined, especially if the frame is wood. (Bed bugs have an affinity for wood and fabric more so than metal or plastic.) Wooden support slats, if present, should be removed and examined since bed bugs often congregate where the ends rest on the frame. Screw holes, knots and other recesses are also common hiding places. Headboards secured to walls should be removed and inspected. In hotels, the area behind the headboard is often the first place that bed bugs become established. Bed bugs also frequently hide within items stored under beds. 

Treat or isolate your bagged items. For washable items research shows that dry cleaning, washing in hot water for 30 minutes, or tumble drying for 30 minutes on high will kill all stages of bed bugs. Non-washables are a little trickier.  Items that aren’t needed for a while can just be stored. It takes 2-5 months to kill bed bugs by isolating them in bags (the warmer the temperature, the shorter the survival time for starving bed bugs). Heating bags by placing in direct sunlight is one of the most effective methods during the warm summer months.  Seven pounds of items placed in clear bags in direct sunlight on a 95 degree day will get hot enough to kill all bed bug life stages in one afternoon.  Also, placing bagged items in a chest freezer (0 degrees F) for 8-10 hours is lethal for bed bugs and their eggs. Some toys may be disinfested by cleaning with hot soapy water and/or rubbing alcohol.
It is hard to tell if you’ve been bitten by a bed bug unless you find bed bugs or signs of infestation. When bed bugs bite, they inject an anesthetic and an anticoagulant that prevents a person from realizing they are being bitten. Most people do not realize they have been bitten until bite marks appear anywhere from one to several days after the initial bite. The bite marks are similar to that of a mosquito or a flea — a slightly swollen and red area that may itch and be irritating. The bite marks may be random or appear in a straight line. Other symptoms of bed bug bites include insomnia, anxiety, and skin problems that arise from profuse scratching of the bites.
You should look for traces of the insects in the folds of your mattresses, box springs and other places where they are likely to hide. You might be able to find their papery skins, which get cast off after molting and look like popcorn kernels but are smaller and thinner, Harlan said. They also leave small, dark-colored spots from the blood-filled droppings they deposit on mattresses and furniture. If you can touch the spot with a water-soaked towel and it runs a rusty, reddish color, you're probably looking at a fresh drop of bedbug feces, Harlan said.
Bed bugs are highly vulnerable to heat; exposing them to a certain amount of direct heat will kill them instantly, while lower temperatures can kill them in a matter of minutes. This is why many forms of heat treatments are recommended. Some methods, such as steamers and portable heaters, have been proven effective through professional use and are quickly becoming standard issue in holistic treatment arsenals.
If you think that by discarding the whole bed means getting rid of bed bugs, you are wrong. By moving the mattress and the bed frame, you not only risk moving the bed bugs all around the house, you are also missing out on many other spots these bed bugs could be at. For example, curtains, floor panels and skirting or even the door frames are able to hide these bed bugs very well. The root causes of the infestation must be eradicated fully.
I work @ a hotel, and just found out that one of the rooms has a bed bug problem. I work at the front desk, and never go into the rooms. But i work third shift, and sleep in the chair in the lobby. Just wanted to know what my chances were of catching them? I will be going home and looking just to make sure. But since i work here, and its un-avoidable, what are some things i can do to protect myself from taking them home?
Don't assume your bites are bedbugs. Bites can be hard to identify, even for doctors. Rule out mosquitoes, fleas, mites, and biting gnats by conducting a visual inspection. It's best to collect and identify bedbugs to confirm bites. Look for the bugs themselves or their bloodstains, especially along the seams of mattresses. Further, look for dark spots of insect waste where bedbugs might crawl into hiding places on furniture, walls, and floors.

At room temperature, bed bugs can survive for up to 3 months without feeding. So, even if no one is living in the room, bed bugs can still survive, especially if there is enough moisture in the air. However, to get rid of bed bugs effectively, you should not just rely on bed bug sprays for exterminating the pests, you should have an integrated pest control management program. This includes using various methods for bed bug removal.


You may be tempted to take treatment into your own hands. The nonchemical treatment options — such as heating and freezing — can help reduce the number of bedbugs you’re dealing with but probably won’t get rid of the population completely. Eggs and young bedbugs can be incredibly difficult to locate since they can be small enough to fit inside the head of a screw, Lazarus says.
If you arrive home and discover that you have brought some unwanted guests home with you, immediately notify the hotel of your discovery. Having a possible infestation in hotels and motels can be a public relations nightmare for the owners. Politely ask them to pay for any and all costs incurred to rid your clothing and home of a possible new infestation.

Bed bug bites are caused primarily by two species of the insect Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] Their size ranges between 1 and 7 mm.[7] They spread by crawling between nearby locations or by being carried within personal items.[2] Infestation is rarely due to a lack of hygiene but is more common in high-density areas.[8][2] Diagnosis involves both finding the bugs and the occurrence of compatible symptoms.[5] Bed bugs spend much of their time in dark, hidden locations like mattress seams or cracks in the wall.[2]


One method of applying freezing temperatures to bed bugs entails the use of carbon dioxide (CO2) applied as “snow” with a portable application device, i.e., Cryonite™. When applied directly onto bed bugs, the frozen CO2 will kill them. However, this method is similar to using contact pesticides, that is, there is no residual activity. It can kill only as many bed bugs as the applicator can find. The advantage of using this type of freezing device is that bed bugs may be killed quickly and without the use of more hazardous pesticides. Again, this is not a stand-alone treatment, and it is recommended that it be used as a supplemental to the application of residual pesticides and/or other means of control.

If you suspect that bed bugs might be hiding in items that can’t be laundered or steamed, like books, papers, luggage, shoes, and dry-clean only clothing, you can treat those with a portable bed bug heater. Heaters are a popular way to safely heat-treat items during bed bug treatments, or as a preventative tool for travelers who want to ensure that bed bugs can’t escape from their luggage to infest their home.

Doctors often misdiagnose those afflicted because it is nearly impossible to tell, if you are experiencing an allergic reaction, what bit you. Often healthcare providers and individuals that have been bitten by a member of the Hemiptera order mistake bites for those of a mosquito. The only way to discern, with complete surety, what your bites are from, is to get a sample of what has bitten you.
Probably chiggers -- they are very small, red mites that usually cannot be seen with the naked eye. They are about as small as the period at the end of this sentence. To stop the itching, use OraJel (usually sold for teething babies), which contains benzocaine (an anesthetic). Also, rub in hydrocortisone cream. To prevent chigger bites, wear long pants and stuff the cuffs into your socks.
Bedbugs are small, flat, wingless insects with six legs that, like mosquitoes, feed on blood from animals or people. They range in color from almost white to brown, but they turn rusty red after feeding. The common bedbug doesn't grow much longer than 0.2 inches (0.5 centimeters) and can be seen by the naked eye to the astute observer.  Bedbugs get their name because they like to hide in bedding and mattresses.
Bed bugs are very resilient. Nymphs and adults can persist months without feeding which is unusual for most insects. The ability to survive without a blood meal is longer at cooler temperatures ― potentially up to a year or longer at 55°F or less. In temperature-controlled buildings, a more typical duration is about 2 to 6 months. Consequently, it is usually impractical to leave buildings unoccupied in hopes of ‘starving out’ an infestation. When infested dwellings such as apartments are vacated, bed bugs often disperse to nearby units, or reduce their activity until the unit is reoccupied. 
While most of the bed bugs were wiped out by the chemicals, three groups continued to thrive after being treated with chlorfenapyr, and five groups were still kicking after being treated with bifenthrin. That means that while some bed bugs will respond to these chemicals, others won't—and it's likely that more and more bugs will become resistant over time.
Symptoms may not appear until some days after the bites have occurred.[5] Reactions often become more brisk after multiple bites due to possible sensitization to the salivary proteins of the bed bug.[3] The skin reaction usually occurs in the area of the bite which is most commonly the arms, shoulders and legs as they are more frequently exposed at night.[5] Numerous bites may lead to an erythematous rash or urticaria.[5]
My 9 yr old was diagnosed with PN, her nodules are so omggggg all I can do is cry and pray for her because it’s only her itching and 5 different doctors that can’t help me tell my Autistic beautiful lil girl your still so Beautiful, she cries. I tell Doctor’s she has heart disease and Autism please tell me they say I don’t know here is cream. Soooo cried out and helpless and depressed I am and so is she, please please help…
Now that you’ve killed the bed bugs hiding in your bed, it’s time to put up defensive measures to keep them out. Remember, bed bugs can be hiding in all sorts of cracks and crevices throughout your bedroom – in furniture, along baseboards, and inside of the walls – so you need a way to keep them out of your freshly treated bed. By cutting off the infestation’s food supply (you), you halt their breeding and reproductive cycle, making the treatment a whole lot easier.
Once you’ve vacuumed and chemically treated your mattress and box spring, enclose them in encasement bags. If the bed bugs found a way inside the mattress, the odds are that the spray chemicals did not kill them. Encasement bags have special zippers that trap the bed bugs and prevent them from escaping. Keep these bags on for at least a year because a fully fed bed bug can live more than 10 months between meals.
Low toxicity contact sprays like SteriFab™ or Bedlam® are likely to kill bed bugs only on contact. Alcohol- and soap-based sprays, are only partly effective. All of these products, once dry, are likely to provide no further control. Eggs will not be killed by alcohol-based sprays, so repeat treatments are usually needed. Be careful when using sprays containing alcohol because they may be flammable.
When you face a serious bed bugs infestation at home, you would want to get rid of bed bugs fast because bed bug bites are the worst nightmare! Bed bug bites can be itchy and painful, resulting in skin allergies for many people. When bed bugs are fully fed (they feed on human blood), the female ones are able to quickly reproduce. How to get rid of bed bugs fast?
Fumigation using a penetrating gas is another way to de-infest dwellings or furnishings, but the procedure is only offered by certain companies. True fumigation is not the same as setting off a total release fogger or ‘bug bomb.’ (It should be noted that bug bombs are considered ineffective in the treatment of bed bugs, and can be quite dangerous if misused.) The fumigation process is technically complex and requires vacating the building for a period of days. The building is then sealed and injected with a lethal gas, usually sulfuryl fluoride. Because the entire building must be vacated, structural fumigation is logistically more challenging with multi-unit buildings such as apartments, than for single family homes. Bed bug fumigations tend to be more common in southern and western states, where the procedure is also used to control certain types of wood-dwelling termites.  

Inspection requires knowledge, dedication and time. At minimum an inspection should involve a detailed examination of mattresses, box springs and bed frames, as well as likely hiding places for bed bugs within 20 feet of beds and other places where residents may sleep or rest, e.g., on couches). Clutter-free space will be needed to allow furnishings to be moved and manipulated for inspection. In general, rooms with more furnishings will take more time to inspect.
The scientific name for bed bugs is Cimex lectularius. They are small creatures that grow up to 5 mm in size, or about the size of an apple seed. They have a flat oval-shaped body and will become significantly larger if they have fed. According to the United States Environmental Protection Agency, bed bugs start life as a tiny egg, then grow into a nymph before becoming an adult.1
What’s the best way to get rid of bed bugs? Stop feeding them. To prevent those unwanted dinner guests, isolate your mattress from the rest of the room. Start by pulling the bed away from the wall and away from other furniture like nightstands and chairs. Remove box spring skirting that hangs down to the floor. Oversize blankets that drape to the floor can also act as a ladder for the little buggers.
Scabies is very common in shelters. Permethrin. Cream applied head to toe then wages off in the shower the next morning should clear it up. Also ALL bedding must be washed in hot borax and ammonia water the best day. All surfaces must be wipe down with 50% water and 50% rubbing alcohol. Thorough vacuuming of the bedroom washing curtains and miniblinda. All clothes must be washed in hot water. Good luck
People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
