After seeing a post about ant bait, I ordered the Terro Liquid Ant Baits as we seem to have a yearly influx of ants every spring and just like clockwork they returned a few days ago, this time in both the kitchen and bathroom. I put a few down in both rooms and the kitchen ants were gone within 48 hours, they went crazy for the bait. The bathroom is taking a bit longer, but there doesn't seem to be as many in there, I am hopeful though.
Hoping this gets rid of them for good, but am grateful for the recommendation!
