I have ants too! We just started noticing it about 2-3 weeks ago!! I have these things!! I scream every time I see one!! I don't know where they are coming from...And we have tried the baits--two different kinds and they are not working!! We tried the Raid brand once before and they seem to work but that was over a year ago! My neighbors are neat freaks and they had ants too and the baits seem to work for them...After reading all this, I am debating which Terro to try? The bait or liquid formula? I have kids so I am really worried about the liquid formula. How does it work? Do you just put some on some paper and just put it in various spots?
