The other day I noticed a big swarm of them around my porch eaves. I looked and they had found a chink in the trim and crawling in and out. I waited until night and risked putting a screw in to close up the gap. I first sprayed a good dose of ant and roach killer in it. The last several days they are still swarming around it. I have managed to kill some off, but more keep coming. Beside the ant and roach killer, I have tried malithion, soapy water, and windshield deicer. Today I tried the shop vac. It sucks them up pretty good. After I have a bunch of them, I shut it off and dump in a little lacquer thinner. Yes, I am being careful to clear it out before turnign the vac back on.
What will kill them and keep on killing any new ones?
