* Typically used for control of wood-destroying organisms, true fumigation of structures is occasionally performed for bed bug control. Fumigating a structure involves “tenting” it, i.e., draping and sealing it with tarps so that the fumigant, a poisonous gas, can be applied into and contained within the structure where it penetrates the contents and kills all pests within. Like whole-room heat treatments, fumigation has no lasting effect (it leaves no pesticide residue), is labor-intensive, and can damage contents. It is also more expensive, especially in northern states where fumigations are done less frequently. The advantage of fumigation over heat treatment may be that fumigation is more likely to kill all the pests within a structure.
If you live in an apartment or condominium, it’s best to alert the property manager.  A coordinated bed bug control effort using a pest control company is generally needed in such situations. Bed bugs readily move from apartment to apartment, with many people unaware that they have a problem. If one apartment is infested, adjoining units (left side, right side, above and below) should be assumed to be infested unless shown otherwise through inspection or monitoring.  Simply asking tenants whether they have bed bugs is not enough.  In one recent study only half of apartment residents whose homes were determined to have bed, bugs knew (or admitted) they had a bed bug problem.
A definitive diagnosis of health effects due to bed bugs requires a search for and finding of the insect in the sleeping environment as symptoms are not sufficiently specific.[5] Bed bugs classically form a line of bites colloquially referred to as "breakfast, lunch, and dinner" and rarely feed in the armpit or behind the knee which may help differentiate it from other biting insects.[4] If the number in a house is large a pungent sweet odor may be described.[4] There are specially trained dogs that can detect this smell.[2]

If the bed bugs are coming from someplace other than your bed, I’d sprinkle uncalcinated diatomaceous earth around cluttered areas and the walls, and bleach the crap out of surrounding furniture. What the diatomaceous earth does is basically attach to their exoskeleton, dehydrate the insect, and they’ll either die of dehydration or get shredded apart as they crawl. Unless your pet or kid would directly eat the diatomaceous earth, it is safe to be in contact with since it’s not a chemical pesticide and it’s fairly cheap.

Isolating your bed from the rest of the house.  If you don’t use a bed, purchase a frame that gets your mattress off the floor and install bed bug interceptors under all feet of the bed frame to keep bed bugs off your bed while you are sleeping. Interceptors are special platforms or cups that are purchased to prevent bed bugs from climbing on to your bed.  An interceptor can be as simple as a sticky card placed under a bed post (sticky and messy).  Better are one of the commercial pitfall traps made specifically for this purpose.  The Climbup™ Bed bug Interceptor and BlackOut BedBug Detector (Google them) are two such products sold online. Relatively inexpensive, these cups trap bed bugs attempting to climb (or exit) the bed. If you have encased your bedding, treated your bed frame thoroughly and installed interceptors, you will be instantly protected against bed bugs.  Don’t take out your clean bedding or put it back on the bed until the bed has been treated (and dried) and encasements installed. And note that for this method to be effective, beds and bedding must not touch the floor, furniture or walls.  This would provide bed bugs other ways to climb onto the bed and foil your defenses.

Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building.
