I'm a former scientist, using words and an audio recorder as my new research tools to untangle the health and food issues that matter most to consumers. I live in Brooklyn, N.Y., where I cook as much as possible. You can find me in the grocery aisle scrutinizing the fine print of every food item I put into my cart.

As mentioned earlier, applying insect repellent at bedtime will probably not deter bed bugs from biting. When working in severely infested dwellings, there may be some benefit to spraying tops and bottoms of shoes with DEET-based repellents. Those working in bed bug-infested environments may also want to hot wash or run clothing, etc. through a dryer upon returning home or to the office.
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.
Next, apply a bed bug powder into confined areas where it won’t be stirred up into the air. Places like the edges of carpeting, inside deep cracks and wall voids, and inside electrical outlets and light switches (accessed by removing the faceplate with a screwdriver) are good candidates for powders, as sprays can’t reach into these areas quite as well. We recommend using a professional powder applicator, which offers better control when applying the powder.
Traditional methods of repelling and/or killing bed bugs include the use of plants, fungi, and insects (or their extracts), such as black pepper; black cohosh (Actaea racemosa); Pseudarthria hookeri; Laggera alata (Chinese yángmáo cǎo | 羊毛草); Eucalyptus saligna oil; henna (Lawsonia inermis or camphire); "infused oil of Melolontha vulgaris" (presumably cockchafer); fly agaric (Amanita muscaria); tobacco; "heated oil of Terebinthina" (i.e. true turpentine); wild mint (Mentha arvensis); narrow-leaved pepperwort (Lepidium ruderale); Myrica spp. (e.g. bayberry); Robert geranium (Geranium robertianum); bugbane (Cimicifuga spp.); "herb and seeds of Cannabis"; "opulus" berries (possibly maple or European cranberrybush); masked hunter bugs (Reduvius personatus), "and many others".
Treat or isolate your bagged items. For washable items research shows that dry cleaning, washing in hot water for 30 minutes, or tumble drying for 30 minutes on high will kill all stages of bed bugs. Non-washables items that aren’t needed for a while can just be stored. It takes 2-5 months to kill bed bugs by isolating them in bags or heating bags by placing in direct sunlight is one of the most effective methods during the warm summer months.
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.
