Are your DAs those little tiny black ants? I usually get them when it's dry and that's a lot here in MS. My exterminator said they were very hard to get rid of! UGH! What do I pay you for...I wanted to say!! I've tried those little bait strips where you put the liquid on top and yes they treat it as a spa. I put out borax around the places where they come in and they just track it everywhere. Pesty little buggers!!
BUT, I haven't seen the first one this summer in my kitchen. Maybe they did die off after ingesting all the stuff I put out. Maybe it was just a slow release killer.
Now watch me wake up to a black mob of DAs in my kitchen!
