Bed bug bites: reactions and what to expect

Bite reactions can appear up to two weeks after exposure and continue for 2–3 weeks after treatment. That's a skin response — not a failed job.

One of the most common questions after a treatment is: I'm still getting bites — did it work? Almost always the answer is yes. Bite reactions are a delayed skin response to the anticoagulant in bed bug saliva, and can surface up to two weeks after the actual bite.

It's normal to keep seeing new bite marks appear for 2–3 weeks after a successful heat treatment, even with zero live bugs left.

We include a follow-up inspection window and a 6-month guarantee for genuine live activity, so you're never in doubt.
