I have the little black bastages,,, I live in a two story wood frame wood siding house,,, plenty of places for them to enter,,,, I've used raid and whether it kills them or not I don't know but they disappear or die and it's several months before I see them again.
What's worse is this year with all the rain we've had in south Alabama I had fire ants invade my house,,,, how would you like to be in your jammies watching tv in the your den and one of them little red devils bites you on your sack.. I had to treat the whole down stairs with raid fire ant killer and that fixed those little red savages....
If your house goes black you may never get it back...
