What Happens During Chemical Treatment for Bed Bugs

Here is what to expect on treatment day and how to get your home ready.

Treatment Day

Your technician pulls furniture away from the walls, removes outlet covers and baseboards where needed, and treats every crack, seam, and void bed bugs use to hide. Beds, dressers, and upholstered furniture get the most attention since that is where most of the population lives.

Prepping Your Home

You will need to prep beforehand, including washing and bagging bedding, vacuuming mattresses and box springs, and clearing clutter so nothing blocks access to baseboards and closets. For background on bed bug biology and how EPA-registered products are regulated, the EPA’s bed bug resource page is a solid reference.

What to Expect After

Most homeowners notice fewer bites and sightings within the first week, though a few holdout bugs turning up before the second visit is normal and does not mean the treatment failed.
