We sprayed a lot in our kitchen but nothing ever worked for more than a few days. Just cut the end, tip to allow a little liquid to go into the two wells, put ONE of these down on a counter or wherever you see the little buggers and there is a tremendous ant party within hours. It is quite shocking to see at first. Apparently they love this stuff - take it back to the nest and everyone dies. There is a Youtube video claiming that one of these can kill 40,000 ants. I think its true we have not seen an ant for over a week.
