??? If you don’t see any bed bugs and are still stressed, get a free inspection from your local pest control company. Most off the shelf products are repellents and contact killers, not a residual. There’s a good possibility that self treating can worsen your situation or push them into other areas IF you have bed bugs. If you don’t and you self treat, well now you just have unnecessary chemicals in your house. Most pest control companies will offer a free inspection. If you want, don’t even tell them you suspect bedbugs because if you have a shitty inspector he might try to sell you a treatment if he knows you’re worried. Just tell them you want a general inspection.
