My neighbor is infested with roaches. I started seeing some here and there nothing crazy. I bought gel bait to prevent it from getting out of hand. My place is clean as for my neighbor they have a lot of clutter. I told my landlord and he had both of our places sprayed. A few days after I still saw some but now going to 3 weeks I feel like spraying made it worse. My landlord is going to have our places sprayed again. What can I use in between spraying? Something that I can use without having to unplug my refrigerator or remove everything from cupboards. TIA.
