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.  
If you know that you have the bugs. Get sealing covers the kind that encloses completely, one for the mattress and one for the box spring. That will trap those critters inside and they will eventually die in there. Next you will need to decide of what combination of treatments you wish to use. Its a job that you will have to keep up with for some time. Do your research online first.
Chances are, you or someone you know has had a run-in with bed bugs. It might have happened in a scrupulously clean bedroom. Or maybe it was a hotel room, office or college dorm. In the February issue of Scientific American entomologist Kenneth Haynes of the University of Kentucky explains how, after a lengthy absence, bed bugs are staging a comeback. The good news is scientists are intensively studying these insects, and their insights suggest novel ways of detecting the bugs and eradicating infestations. Some of those potential solutions are a long way off, however. In the meantime the best bet is to avoid bringing bed bugs home in the first place. I called Haynes to ask him how to do that and what to do if one suspects an infestation (eek!), among a bunch of other practical-minded questions.
No two people react to bites in the same way, although some reactions are similar. Because of the saliva that they leave behind, the first reaction is usually severe itching and irritation. This is often followed by a raised appearance on the contacted area. Some people, however, react by having welts and hives all over the body. Still others will have small, pinkish bumps that are concentrated in one area.
Encasing mattresses is one of many good parts of a solution, but it doesn't get rid of the infestation. There are going to be other bugs away from the mattress, hiding nearby. What mattress covers are good at is entombing the sometimes large number of bed bugs that can live on a mattress. And because the covers tend to be uniform in color and don't have a lot of seams that the bugs can hide in, it's easier to see the insects.

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.
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
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
