Turns out, C. lectularius is also forming a resistance to other insecticides, according to a study published online April 10, 2017, in the Journal of Economic Entomology. The researchers, from Purdue University, found that three out of 10 bedbug populations collected in the field showed much less susceptibility to chlorfenapyr, and five of the 10 populations showed reduced susceptibility to bifenthrin, according to a post on Entomology Today. The scientists defined "reduced susceptibility" as a population in which more than 25 percent of the begbugs survived after seven days of exposure to the particular insecticide.
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.
Bed bug sprays usually act as an insecticide and repellent. The best kind of bed bug sprays should kill bed bugs on contact and need to be used repeatedly to help eliminate your bug problem. According to the Texas A&M University, bed bug sprays are best used in combination with other bug control methods like natural bed bug powders. This is because bed bugs don’t build up resistance to natural bug powders and products like diatomaceous earth which kills bed bugs as long as the powder is dry.5
Ticks are known transmitters of disease to humans and animals. Tick-borne diseases include Lyme disease, Rocky Mountain spotted fever, Q fever, tularemia, babesiosis, and Southern tick-associated rash illness. Infected ticks spread disease once they've bitten a host, allowing the pathogens in their saliva and mouth get into the host's skin and blood. Tick bites are typically painless, but the site of the bite may later itch, burn, turn red, and feel painful. Individuals allergic to tick bites may develop a rash, swelling, shortness of breath, numbness, or paralysis. Tick bite treatment involves cleaning and applying antibiotic cream.
As bed bugs grow they molt, shedding their skin five times before reaching maturity. A blood meal is needed between each successive molt. Adult females also must feed in order to lay eggs. Under favorable conditions (70-80°F), the bugs can mature fully in as little as a month, producing multiple generations per year. Cooler temperatures or limited access to blood prolong the development time. 

You can also try spraying an insecticide yourself. Just make sure the product you use is intended to kill bedbugs and is made for the type of space you are using it in (some are intended only for outdoor or garage use, rather than for indoor use in areas where you may be sleeping, cooking, and eating, among other things). And know that insecticides available to professionals are usually stronger and more effective than those that are available to consumers. (6)
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.
Bed bug eradication is challenging and it’s prudent to hire a professional when resources allow. However treatment can be expensive, often costing hundreds or thousands of dollars. Those who cannot afford this often must cope with the problem themselves. A useful step that anyone can take to combat bed bugs is to install bed encasements. Covering the mattress and box spring can help eliminate a substantial portion of the bed bug population -- especially if discovered early while most of the bugs are still confined to the bed area. Extra care should be taken when installing budget encasements since these can tear easily, especially on metal bed frames. Ideally both the mattress and box spring should be encased. If only one encasement is possible it’s often best to cover the box spring which is harder to subsequently inspect.
As soon as you determine you have bedbugs, isolate clothing, and start putting them into clean plastic bags. Accuracy is very important, so pinpoint the areas and rooms that need treatment and act swiftly. While some people think over-the-counter sprays are a solution, pyrethroid-based pesticides may kill or repel some of the insects, but can be dangerous if misused, and it's doubtful you'll be successful on your own.
Consider using insecticides. Residual insecticides (usually pyrethroids) are applied as spot treatments to cracks and crevices where bed bugs are hiding. Increased penetration of the insecticide into cracks and crevices can be achieved if accumulated dirt and debris are first removed using a vacuum cleaner. Many readily available aerosol pesticide sprays will cause bed bugs to scatter making eradication more difficult. Dust formulations may be used to treat wall voids and attics.[16]
A number of other symptoms may occur from either the bite of the bed bugs or from their exposure. Anaphylaxis from the injection of serum and other nonspecific proteins has been rarely documented.[5][10] Due to each bite taking a tiny amount of blood, chronic or severe infestation may lead to anemia.[5] Bacterial skin infection may occur due to skin break down from scratching.[5][11] Systemic poisoning may occur if the bites are numerous.[12] Exposure to bed bugs may trigger an asthma attack via the effects of airborne allergens although evidence of this association is limited.[5] There is no evidence that bed bugs transmit infectious diseases[5][7] even though they appear physically capable of carrying pathogens and this possibility has been investigated.[5][3] The bite itself may be painful thus resulting in poor sleep and worse work performance.[5]

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.

To check for signs of a bedbug infestation, Dr. DerSarkissian says that you may notice rusty-colored spots on bed linen and mattresses. These spots could be either blood stains or bedbug excrement. You may also find shed skins around bed frames, mattresses, and other hiding places. Also, a musty smell is usually present where a large number of bed bugs are living.4


Although bedbugs are generally nocturnal, they're like humans—if they're hungry, they'll get up and get something to eat. "If you go away to visit a friend for a week and you come back and sit down on the couch, even though it's daytime the bedbugs will come looking for you," Schal says. Keeping a light on, then, unfortunately does not keep these tiny vampires away.

Systematically treat the room–all cracks and crevices around windows, outlets, blinds, pictures, posters and clocks on walls, baseboards, under edges of carpets and any other crevices or void areas in the room. Remember that immature bed bugs are very tiny. Dozens of bed bugs can hide in a recessed screw hole in a bed frame or dresser. Therefore it’s important that no hiding place be overlooked. Treatment can include vacuuming, but should not be limited to vacuuming only. Vacuums do not remove eggs, and will likely not remove all bed bugs from deeply infested cracks and crevices. Vacuums can remove many bed bugs from mattresses and the exterior of box springs (remember to immediately double-bag the vacuum bag after cleaning and dispose of outside in a trash can or dumpster). Sticky tape is another method of picking up bed bugs from furniture, walls, etc.
You’ll likely only see them in their hiding spots or crawling across the floor since, unlike other insects, bedbugs cannot fly or jump. Durham says to check along the edges of your mattress. You may see the exoskeletons that bedbugs have shed as they matured, or you may notice a musty smell, both of which indicate there could be bedbugs in the area. It can also be helpful to check your bed with a flashlight during the middle of the night (since these crawlers tend to be more active at night.)
Bed bugs are an increasing cause for litigation.[69] Courts have, in some cases, exacted large punitive damage judgments on some hotels.[70][71][72] Many of New York City's Upper East Side home owners have been afflicted, but they tend to be silent publicly in order not to ruin their property values and be seen as suffering a blight typically associated with the lower classes.[73]
Inspection for bed bug infestations must be very thorough. Your primary tool is a flashlight. Since bed bugs are cryptic insects and spend most of their time hiding, you will need a flashlight to find them. You must move and/or disassemble some items while searching including beds, dressers, carpets and rugs. While you inspect, be alert for a bed bug smell which has been described as an obnoxious sweetness or fresh, red raspberries. You should also look for accumulations of cast nymphal skins and for stains of blood spots on sheets and linens. A common location for bed bug infestations is a box spring. The framework is often made of wood and contains cracks can crevices suitable for harborage. Other common areas include wall voids, behind switch plates, interior corners of bedside tables, under the edges of wall to wall carpeting, couches and stuffed chairs.
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]

Bed bug incidents in schools are best handled by knowledgeable pest control firms. Widespread insecticide treatment of classrooms, hallways, buses, etc. is unnecessary, ineffective and imprudent. Effort instead should be spent checking chairs, desks, lockers, coat rooms, etc. in the vicinity of where the bugs were found, and treatment should be focused on those specific areas. Canine inspections can also be useful in finding small numbers of bed bugs in schools and other establishments where there are no beds.      

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.
Itchy swollen bites may be the first sign of a bed bug problem. However, these itchy bites can take as long as 14 days to develop in some people, so it's important to look for other clues if you are concerned about an infestation. Bed bugs typically infest mattresses, box springs, bed frames, and couches. You may be able to find them hiding within the cracks and crevices of beds, furniture, floors, and walls. Bed bugs often leave evidence of small dark stains (fecal droppings) and rusty red spots (bloodstains) on bedding sheets, mattresses, and other areas they hide in or travel along. Heavy bed bug infestations can cause a sweet, musty smell.
