Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective. An hour at a temperature of 45 °C (113 °F) or over, or two hours at less than −17 °C (1 °F) kills them. 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). 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. This method is expensive and has caused fires. Starving them is not effective as they can survive without eating for 100 to 300 days, depending on temperature. One expert recommends not trying to get rid of bed bugs exclusively on one's own.
Insect bites, including those from the bedbug, have been proposed as a factor contributing to the formation of a cutaneous reaction termed papular urticaria. Patients with papular urticaria have been shown to demonstrate immunoglobulin (Ig) G antibodies to bedbug (C lectularius) antigens.  Thus, IgG against C lectularius, Cimex pipiens, and Pulex irritans in patients with papular urticaria may contribute the pathogenesis of this condition.
We are often asked, "How do you kill bed bugs?" While we would love to give a simple answer, this is actually a loaded question. There are many ways to kill a bed bug but, if you want to kill all of the bed bugs in your home or business, it is important to pay attention to the details. Here are some ways you can kill bed bugs, and what you should know about each.
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.
First up is the most commonly recommended tool by far: rubbing alcohol diluted in water. This is suggested because alcohol can kill bed bugs on contact, and evaporates shortly after, so it’s considered safe for use pretty much anywhere in a home. A recurring theme in these recommendations are household items that are considered to be safer for people than mainstream chemicals.
To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.
Heat treatments of this type are advantageous because they present no pesticide hazard. However, they also provide no residual activity. That is, they do not prevent a structure from being re-infested after it is heat treated. For this reason, residual pesticides are often applied in conjunction with heat treatments. Such applications may not prevent re-infestation, but help control any bed bugs not killed by the heat. A certain percentage of heat treatments, perhaps 10 to 20 percent, fail to kill all the bed bugs present. Often this is due to residents failing to adequately prepare the premises for heating.

Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
Wash the bites with soap and water. Wash the area with mild soap and water; use a bar of soap and enough water to wet surface of your hands. Work the soap in your hands into thick, soapy lather. Rub the lather over the affected area liberally. Repeat until the entire area is covered. Leave on and do not rinse. Allow the soap lather to dry over the bitten areas. You should experience immediate relief from itching.
Minimize its spread. First, notify your landlord if you rent in a building to control its spread to other units. Thoroughly vacuum any infested areas, including carpets and mattresses, and then empty the vacuum bag into a plastic bag, seal it, and throw it in the trash outside. If you can’t get the bed bugs out of your furniture, discard items in a responsible manner. To avoid someone else from salvaging infested furniture or mattreses, rip, remove stuffing, or spray paint with the words “bed bugs.”
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
Both of these types of Hemiptera are sensitive to extreme temperatures. It may be necessary to rid the infestation by exposing the area to extreme heat or cold; they are most comfortable in temperatures around eighty degrees Fahrenheit. Raising the temperature to ninety-seven to ninety-nine degrees may kill off a significant portion of the population.
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.
Discard affected items. In some cases, infested mattresses and box springs will need to be discarded. Since bed bugs can disperse throughout a building, it also may be necessary to inspect adjoining rooms and apartments. Pay it forward: chop up and/or damage the items you discard so nobody will be tempted to take them home and spread the problem further.
How to treat and prevent chigger bites A chigger is a form of mite that feeds on human skin cells. Although they are so small that the naked eye cannot see them, chiggers can inflict extremely itchy bites that can last up to a week without treatment. Here we look at how to avoid getting bitten as well as how to recognize and treat any existing bites. Read now
Bed bug bites: What you need to know Bed bugs are small, parasitic insects that feed on human blood. They often bite humans during the night or early morning when people are asleep. While they don't carry disease, they can cause irritation, sores, and itchiness that might prevent a good night's sleep. Learn how to identify, control, and prevent bed bugs. Read now
Discourage bed bug infestation by keeping clutter picked up, washing bedding and upholstery routinely and not buying used furniture. When you’re traveling, lower your risk of bringing bed bugs back home by opening your suitcase on a hotel desk or luggage rack instead of on the bed; keeping your belongings in your suitcase, not unpacked in dresser drawers; sealing dirty laundry in plastic bags that can be taken straight to the laundry room at home; and inspecting your luggage for bed bug activity before you bring it into your bedroom.
Unlike cockroaches and flies that feed on filth, there is often no relationship between bed bugs and cleanliness. Since the bugs feed solely on blood, pristine dwellings can be as vulnerable to infestation as are places of squalor. That said, poverty and privation can lead to increased risk of bed bug problems, as can the inability to hire a professional exterminator.
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.
Bed bugs have been pestering humanity for thousands of years, but in the 1950s they finally met their match: the pesticide DDT. Then DDT was banned, but for most of the 40 years since, bed bugs have not been a major problem. Now, however, these blood-sucking vermin are back with a vengeance. That’s the bad news. The good news is that, unlike mosquitoes and ticks, bed bugs don’t spread disease, and there are practical steps you can take to prevent an infestation. And if you do get bed bugs, you can get rid of them yourself. We’ll show you what to look for, how do you get rid of bed bugs if you find them, and how to keep them out!
If all other options have been exhausted, you may need to seek a professional PMP (Pest Management Professional). There are pesticides that are approved for professionals to use during a infestation. These pesticides, however, are not always effective, and typically not as effective as steam cleaning, excessive heat, or excessive cold. The exterminator may opt to treat the area with carbon dioxide.
According to the Texas A&M University, there are no “magic” insecticide sprays for bed bugs. However, both natural and chemical sprays have a measure of effectiveness against bed bugs. One of the benefits of chemical sprays is that they are stronger and will kill off bed bugs quicker. However, the drawback is that many populations of bedbugs have become resistant to pyrethrins and pyrethroids – the 2 main chemicals in many chemical bed bug sprays. Therefore, they may not be effective in reducing many bed bug populations.5
It often seems that bed bugs arise from nowhere. The bugs are efficient hitchhikers and are usually transported into dwellings on luggage, clothing, beds, furniture, and other items. This is a particular risk for hotels and apartments, where turnover of occupants is constant. Bed bugs are small and agile, escaping detection after crawling into suitcases, backpacks and belongings. Acquiring secondhand beds, couches and furniture is another way that the bugs are transported into buildings. Bed bugs also can be carried in on one’s clothing, shoes or wheelchair. Once bed bugs are introduced, they can crawl from room to room or floor to floor. They can also be transported throughout buildings on people and their belongings.
"In the past, bedbugs have repeatedly shown the ability to develop resistance to products overly relied upon for their control. The findings of the current study also show similar trends in regard to chlorfenapyr and bifenthrin resistance development in bedbugs," study researcher Ameya Gondhalekar, research assistant professor at Purdue's Center for Urban and Industrial Pest Management, said in the Entomology Today statement. "With these findings in mind and from an insecticide resistance management perspective, both bifenthrin and chlorfenapyr should be integrated with other methods used for bed bug elimination in order to preserve their efficacy in the long term."
These nocturnal creatures can hide in beds, floors, furniture, wood, and paper trash during the day. We humans usually become their dinner during the night, with peak biting activity just before dawn.They can obtain their meal in as little as three minutes, after which they are engorged and drop off the host, then crawl into a hiding place to digest their meal. Bedbugs can live for 10 months, and can go weeks without feeding.
The life cycle stages of a bed bug are egg, nymph, and adult. The reason they are called bed bugs is that they readily infest mattresses, bed frames and box springs. Eggs are laid along the edges of or around buttons on the mattresses. Eggs can also be glued to rough surfaces. Bed bug females lay about 200 eggs, usually at the rate of three or four a day. Eggs are placed in cracks, crevices and other isolated and protected shelters. Females lay eggs after a blood meal. Eggs will hatch in one or two weeks into Nymphs. Newly hatched bugs (Nymphs) begin feeding immediately. At room temperature, and with an available food supply, the nymphal period will last 14 to 30 days. They shed their skin (Instar) five times before becoming adults. Bed bugs will mate soon after becoming mature, so the time from egg hatch to egg laying is 4 to 9 weeks, under favorable conditions. The average life span of the bed bug is 6-12 months and they feed every 10 days or so during this time. Bed bugs can survive many months without a blood meal and their reproduction is high.
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.
Because bed bugs have become so prevalent in the past few years, many fear they’ll be their next victim. They became so anxious and paranoid of the possible bed bug presence. If you eliminate the pests though, you could have a certain sense of peace knowing that you would not be bothered or bitten them. However, you wouldn’t be able to sleep well for long if you would not kill bed bugs right and continuously do the bed bug preventive steps.
Treat other areas in your home. This is perhaps the most challenging part of do-it-yourself bed bug control. If you catch an infestation early you may not need to do anything more than treat and isolate your bed as described above. But if an infestation has spread to other parts of the home, bed isolation may not be good enough. Here is where professional help may be needed, especially if you’re not up to moving furniture. Still determined? Here are some tips that may improve your chances of success:
