Wash infested bedding in hot water, between a temperature of 97° and 99°F. Infested furniture can be set outside during cold weather to kill all stages of bed bugs. At 0° F, two days is sufficient to kill bed bugs while four to five days is required when the temperature is about 20° F.

Often, exterminators will spray a “contact kill” spray on bedbugs seen in the apartment (such as a mixture of cyfluthrin, pyrethrins, and piperonyl butoxide), and then spray lambda-cyhalothrin on baseboards and other areas of the apartment. Lambda-cyhalothrin acts as a “slow kill” barrier which kills bedbugs after they cross it, and is usually microencapsulated, making it safe to pets and humans after it dries. Often, deltamethrin is also injected into various cracks and crevices of the apartment. The lambda-cyhalothrin and the deltamethrin are at their strongest for the first two weeks following their application, but in total usually last for 60 days.
