Frequently asked questions
Is it safe to spray bed bug killer directly on my mattress?
Yes, if you choose a spray labeled for mattress use. Look for non-staining, low-odor formulas that are EPA-registered for indoor use. Always allow the mattress to dry completely before sleeping on it.
How long does bed bug spray last on a mattress?
Residual protection varies from a few days to several weeks, depending on the active ingredient. Synthetic pyrethroids like permethrin can last up to 6 weeks, while natural sprays may need reapplication every few days.
Will bed bug spray stain my mattress?
Most sprays formulated for mattresses are non-staining, but always test on an inconspicuous area first. Avoid over-wetting the mattress to prevent potential damage.
Can I use bed bug spray on my mattress if I have pets or children?
Yes, but choose a non-toxic, natural spray if concerned. Even synthetic sprays are safe once dry, but keep pets and children away until the mattress is completely dry.
How often should I reapply bed bug spray?
Follow the product label instructions. For ongoing infestations, reapply every 1-2 weeks for chemical sprays, or more often for natural sprays. Combine with other treatments like encasements and steam cleaning.
