These didn't kill the colony

After trying our usual brand of baits/traps, and still having so many big ants, I told my husband to buy the powder, but he brought these home instead. They just sat there on our kitchen floor, not collecting ants. I never saw one ant near them, they were all crawling on my counters & in cupboards. So no, these didn't kill the aggressive colony this year. I ended up using a foam that worked.

I used these baits a few years, and sometimes they work, sometimes they don't. A few years ago they worked just fine, and a few weeks after I put them out I didn't see any ants around. This year the ants just avoided the thing - they just walked around, seemingly not attracted to the bait inside. I do have to mention that these need to be out for a while, don't expect results overnight.
