Every year in April or May, like clockwork, those pesty little ants make an appearance in my kitchen, usually after a rain. They must be getting in somewhere in the tiniest crack near the foundation. TERRO is the answer to getting rid of them. BUT, the TERRO will draw more ants initially! That's what you want, as much as it bothers you to see them crawling around, you need to refrain from killing them with your hand, etc.
TERRO has the liquid in the clear plastic traps. Some of the ants crawl right into the traps and will drown, will others get in there and take the food back to the nest to the Queen. You have to be patient and let them eat and walk in the liquid so they bring it back to the Queen. Once the Queen gets the liquid and she dies, the nest/colony is finished and the other ants die without the Queen. A nest/colony will NEVER die, unless the Queen is dead.
Here's what I do. I open a few of the clear plastic Terro traps and put them in the area, usually around my kitchen sink. I take one more Terro trap and squeeze some of the liquid directly in that area as if it spilled out. Some of the (worker) ants get right to it and go directly to the area that I spilled out, while some crawl into the other traps. Spilling some out hastens them getting the liquid and bringing it quickly to the Queen. You have to give it a few days, and sometimes a little longer up to a week, but it works!
Just so you know, in additon to the liquid inside traps, there are also TERRO stakes that you can put outside the house in the ground near the foundation where you feel they're probably coming from or getting in. The main thing is to be patient (as hard as it is) and let the liquid do its thing and it does work!
One last important thing. Do NOT wipe or clean up around where you put the Terro ant traps. Ants always follow a trail back to the nest, and if you wipe down or clean up that area where they are, you break the trail for them and then they don't get back to the nest to give the Queen the poison.
