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.
Bed bug bites usually do not pose a serious medical threat. The best way to treat a bite is to avoid scratching the area and apply antiseptic creams or lotions and take an antihistamine. Bed bug infestations are commonly treated by insecticide spraying. If you suspect that you have an infestation, contact your landlord or professional pest control company that is experienced with treating bed bugs. The best way to prevent bed bugs is regular inspection for the signs of an infestation.
Bedbugs are most often found in hotels, hostels, shelters, and apartment complexes where lots of people come and go. Because bedbugs hide in small crevices, they can hitch a ride into your home on luggage, pets, furniture, clothing, boxes, and other objects. Bedbugs are found worldwide, but are most common in developing countries. Once rare in North America, they may be on the rise due, in part, to increases in international travel.

I can definitely understand. This is has been going on with us for almost a year. My hands and arms look like I have leprocy or something. Horrible blisters, rash, scabs, and bunches of “bumps” especially in my right hand. I wind up with painful blood blisters some times. I am living on benedryl and calamine lotion. I hate going out because of what I look like. I have taken to using cover up and foundation on my hands to make the mess less noticable. i have a long-sleeved summer weight sweater that I wear whenever I do have to go out.
The effective use of pesticides for bed bug control typically involves a thorough inspection during which the technician will kill any bed bugs he/she discovers, applying contact or residual pesticides directly on the bugs. This is followed by residual application to all cracks, crevices and voids, likely to harbor bed bugs. The pesticide used should be one that remains active for weeks, allowing bed bugs that were missed on the initial inspection to contact treated surfaces long enough to receive a lethal dose.
One of the easiest ways to identify a bed bug infestation is by the tell-tale bite marks on the face, neck, arms, hands, or any other body parts while sleeping. However, these bite marks may take as long as 14 days to develop in some people so it is important to look for other clues when determining if bed bugs have infested an area. These signs include:

After treating a mattress or box spring for bed bugs, we recommend encasing each in a bed bug proof cover. This will prevent re-infestation and will make future inspections and treatments easier. Be sure any product that has been sprayed or applied to your mattress is dry before you cover the mattress with a bed bug proof cover. You can make the bed with your freshly laundered linens over a bed bug proof mattress cover.


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]


This question is answered by the condition of the mattress and the size of infestation. If there are holes or tears in the gauze fabric or fabric of the mattress, bed bugs and eggs may be inside, as well as outside. There are restrictions on how beds can be treated with insecticides. We carry both Mattress Safe Bed Bug Encasements and ActiveGuard Mattress Liners.
CrossFire Bed Bug Concentrate has two different active ingredients for dual modes of action (both a quick kill and residual activity). Mix 3 oz of CrossFire Insecticide with one gallon of water or 0.75 oz per quart (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. 

Conventional insect repellents, like those used to deter ticks and mosquitoes, do not appear to be as effective against bed bugs. Therefore, attempting to avoid being bitten by applying insect repellent at bedtime is not recommended. Sleeping with the lights on is also not likely to deter hungry bed bugs, as they will adjust their feeding cycle to the host’s sleeping patterns. 

Bed bugs were mentioned in ancient Greece as early as 400 BC, and were later mentioned by Aristotle. Pliny's Natural History, first published circa AD 77 in Rome, claimed bed bugs had medicinal value in treating ailments such as snake bites and ear infections. (Belief in the medicinal use of bed bugs persisted until at least the 18th century, when Guettard recommended their use in the treatment of hysteria.[51])
