Harris Bedbug Killer 32 Oz. kills bedbugs and lice and comes with a trigger spray for easy application. We recommend using this product in combination with our bed bug aerosol egg kill on mattresses, box springs, walls, floors and carpets and following up with diatomaceous earth bed bug powder behind electrical outlets around switches where bed bugs tend to congregate. The odorless, non-staining formula kills bed bugs after the spray dries.
