My kitchen has tiled walls & I noticed little black ants coming out from between the tiles near my sink, going down into the sink and trying to clean the dirty plates from lunch.
Some ants like sugar, and some like grease. So I used a little peanut butter and breadcrumbs mixed with boric acid and rolled into a ball and put that in one place, and put a little boric acid in some pancake syrup, made a thick paste and put that on a small piece of plastic lid on the other side of the counter.
Got two different sets of ants taking the two different baits, one set a little bigger than the other! (The big ones are going after the sugar bait, the smaller to the PB)
It is seriously grossing me out to see them there, but I know that will soon cease as they feed this stuff to their queen & the larvae. Killing them at this point would be counter active for me, although my instinct is to beat the daylights out of 'em.
Shudder. If that doesn't work, I'll see what that Terro stuff y'all are talking about might do for us!
If I had ants all over the house in everything including my chair, I'd seriously suspect termites.
