Update: went with bait stations over a perimeter spray for roaches in my Grant Park rental
I had a light German roach thing in the kitchen of my Grant Park duplex, maybe 5 or 6 sightings in a week, mostly under the sink at night. I told myself I could just spray the baseboards myself, but a neighbor who works at a property management office told me that only kills the ones that walk through it. So I paid $180 for a guy to put down gel bait and a few stations near the fridge and sink instead. Two weeks in and I have found one dead one and zero live ones. Did the bait thing actually work for you, or did it just push them somewhere else in the house?
