I spied half a dozen ants around my kitchen sink early this afternoon, so I put a couple of drops of Terro ant killer on this cardboard and placed it on the window sill over the sink. Now I have many more ants than I started with. The few close enough to smell it went and told their friends. Which is good because they’ll carry it back to the nest and kill the entire colony.
I’ve been using Terro in a hidden area to get rid of ants elsewhere around the house. This is the first time I’ve used it where I could see the feeding frenzy. I’ve already added more Terro because the ants were down to bare cardboard.
