A can is not the treatment
Best bed bug sprays
The best bed bug spray is a labeled contact product for cracks you have opened and can see. It is a weak plan if it is the only thing you buy. Bed bug eggs and harborages in a box spring, an outlet, and a suitcase survive a mist across the sheets. Buy the encasement and the interceptor first. Add spray only where the label allows, and do not fog the bedroom.

Which one to buy
Labeled product
Harris bed bug killer spray
Best consumer spray — Harris-type bed bug spray. Follow the label for mattresses. Many labels restrict how you treat a surface people sleep on. Keep it off skin. It will not reach a closed box spring.
Hardware
Protect-A-Bed mattress encasement
Best money first — Encase instead of soaking the bed in spray. You still have to treat or heat the rest of the room.
Labeled product
Hot Shot indoor insect fogger
The can to skip — Total-release foggers are a known poor match for bed bugs. They do not penetrate harborages and they add fire and exposure risk. Do not buy one for this pest.
What to buy around the spray
Hot dryer cycles for clothes, a zippered encasement, interceptors, and a flashlight for seams. In an apartment, the adjacent unit matters. Over-the-counter spray has not replaced heat and professional programs for heavy infestations. If you are being bitten after a careful two-week attempt, hire someone who will inspect, not fog.
Common questions
What is the best spray to kill bed bugs and eggs?
No consumer mist reliably reaches eggs inside a mattress seam you did not open. Encasements, heat, and a label-directed crack treatment beat another can.
Is it safe to spray the mattress?
Only if that product’s label allows that surface, at that rate, with the dry time and the covering rules it prints. Many people over-treat the place they sleep. When the label is unclear, do not improvise.
Will a fogger work if the spray did not?
No. Foggers are a worse match for bed bugs than a crack-and-crevice approach. Stop and change the plan.
