The principle behind heat treatment is simple:
120⁰F is the magic temperature: Bed bugs begin to die when the ambient temperature reaches 113 ⁰F, and die within minutes at 120⁰F.
Kills all life stages: All life stages of bed bugs from eggs to nymphs to adults, will die with heat.
Safe: These temperatures are low enough to be safe for almost all of your belongings, including electronics.
Guaranteed to kill all bed bugs.
Heat treatment has several benefits over treating bed bugs with chemicals like pesticides. Most pesticides require repeated treatments and residual sprays that stay in your house for weeks. With heat treatment there’s no danger of chemical misapplication (and possibly resulting injuries), or even just the inconvenience of repeated servicing and furniture that reeks of pesticides. Unfortunately, there’s also the fact that bed bugs are very adept at quickly evolving resistance to pesticides. In the last couple decades the pesticides that were the most effective at killing them, DDT and pyrethroids, have become near useless against bed bug populations. While new pesticides are constantly being developed their use will always be an uphill battle; an arms race against a pest that has nature on its side. Using heat treatment for bed bugs has no risk of developed resistance, and can also be used alongside conventional pesticide treatments; for example, many pest control professionals treat items like mattresses, bedding, clothes, children’s toys etc., with heat while spraying residuals over the dwelling itself.
