My wife and I rent a really nice house but there's one glaring problem....ROACHES!!!! The tenants that be here before us be absolutely repulsive. Anyway, we had an exterminator come out a few weeks vertebrae and spray. We've seen a noticable difference, but they're still around. The exterminator cant' come out for another two weeks but this problem is disguisting and wants to be solved now. Any over the counter products I can use BESIDES BOMBS (I hold 2 cats and 2 dogs) that will effectively get rid of these things???
Is the cold dampen from the bathroom sink...
Answers:    No foods, hose down indoor for 2 weeks.
Make nests of old towers outdoor near fat+borax baits inside bottles to lure them adjectives out.
Compact Fluorescents (CFL) Mercury within the house?
the exterminator should have tlod you it would pocket several treatments he should placed bait out and then come hindmost and reapply once a month for a few months might take 6 months to capture rid of all depending on how discouraging they were
