Once you’ve vacuumed and chemically treated your mattress and box spring, enclose them in encasement bags. If the bed bugs found a way inside the mattress, the odds are that the spray chemicals did not kill them. Encasement bags have special zippers that trap the bed bugs and prevent them from escaping. Keep these bags on for at least a year because a fully fed bed bug can live more than 10 months between meals.
Some pest control firms also employ commercial steamers or spot-freezing equipment to treat areas where bed bugs are found or suspected. Used correctly, they kill bugs and eggs on contact. Neither method, however, affords residual protection against bed bugs which may have been missed. Steaming and spot-freezing equipment also have limited ability to penetrate fabric, wood, and other materials where bed bugs often reside.
A hair dryer might seem like a safer way to kill bed bugs with heat. Unfortunately, their maximum temperature is rarely more than 150 degrees. That heat level can kill bed bugs, but only if you maintain the heat over them for several minutes. So unless you want to follow each bug you see around with a hair dryer until they eventually die, you’d probably be better off just hitting them with the thing.
As for traps, these capture methods may not be full-proof for all bedbug species. Researchers have found that while both the common and tropical bedbug species have hairy feet, C. hemipterushas denser foot hairs, making this tropical insect an expert climber on slick surfaces. In the study, detailed on March 15, 2017, in the Journal of Economic Entomology, the researchers found that adult tropical bedbugs were much better at escaping traditional pitfall traps, which held onto most of the common bedbugs in the study.
To know it's bedbugs, it's important to find the bugs themselves. Look at bedsheets and mattresses for little spots of blood, rusty-looking stains (crushed bugs), or black dots (bugs' poop). You might see live bugs around the seams or tags of mattresses and box springs, or in cracks of bed frames and other furniture. They can even hide in books, carpet edges, and electrical outlets.
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). Go to http://www.amazon.com and search for “bed bug mattress protectors”.
You’ll likely only see them in their hiding spots or crawling across the floor since, unlike other insects, bedbugs cannot fly or jump. Durham says to check along the edges of your mattress. You may see the exoskeletons that bedbugs have shed as they matured, or you may notice a musty smell, both of which indicate there could be bedbugs in the area. It can also be helpful to check your bed with a flashlight during the middle of the night (since these crawlers tend to be more active at night.)
