To ensure that all bed bugs are killed, reapply the contact and residual sprays two weeks after the initial treatment, then again two weeks after that, for a total of three applications. These reapplications make sure that any eggs that have hatched will be killed off so that they can’t create a new infestation.

The study concluded that using these essential oils in a bug spray can be an effective way to reduce bed bug populations without putting humans at risk of exposure to chemicals.8
