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.
Pull carpet edges back from walls. Being careful, take a pair pliers and gently grab the corners of the carpet and pull the carpet back about 1 foot. Do this one wall at time during treatment. After treatment as described below, replace the carpet and tuck under the baseboards. If you do this 1 wall at time you will not usually need to re-stretch the carpet.
While alcohol can kill bed bugs on contact, it’s not going to kill nearly enough of bed bugs to be considered effective. In lab studies, even 99 percent concentrations of alcohol only killed between 40% to 60% of the adults that were sprayed. On top of that, alcohol has no long-lasting residual effect, and doesn’t affect bed bug eggs. 60% sounds good, but a contact killer should be able to kill a lot closer to 100% of the bed bugs you see. Otherwise, a shoe or a blowtorch would be the more reliable tool for the job. (Editor’s note: please don’t use a blowtorch.)
Dessicants are substances that destroy the bugs’ protective outer coating. Without this coating, the bugs dry out and die. Two examples of dessicants are silica aerogel (Tri-Die and CimeXa) and diatomaceous earth. The advantage to dessicants is that bedbugs can’t become resistant to them, but they work slowly. These products can take a few months to kill off all the bugs.
Stripping and vacuuming the mattresses and box springs, and encasing them. Double bag your bedding and wash in hot water and dry for at least 30 minutes (discard the inner bag after putting bedding into the washer, as it could have bed bugs). After vacuuming suspected bed bugs from the bed, take your vacuum cleaner outdoors and remove and discard the bag. Purchase a good quality set of bed-bug-proof encasements for your mattresses and box springs. Bed bug-proof encasements are fabric sacks into which you slide your mattress or your box spring. The zippers on bed bug encasements are designed to be tight enough to prevent even the smallest life stages of the bed bugs from escaping. Also, good bed bug-proof encasements are woven to prevent bed bugs from biting you through the encasement. A good encasement will trap all bed bugs in the mattress and box spring inside, and will be smooth on the outside, providing few places for bed bugs to hide. Sears, Target, Walmart and other stores may sell bed bug-proof encasements, but these can also be purchased online. A good place to look for different brands and reviews of mattress encasements is Amazon.com (whether you buy there or at a local store).
