I've been trying to poison some ants. They are actually in my kitchen, but they come from the garden, so I hope I'm on topic here.
In the past I used Grant's stakes. After a few days of feeding on the poison the ants would be gone for about a year. This year the ants refused to eat the Grant's bait. I even tried removing some from the pod and mixing some water with it. The ants just were not interested. These ants want MEAT. I live in the Silicon Valley, and we have very very tiny ants. People say they are Argentinean ants.
When the Grant's failed I bought Raid and Combat bait stations. The ants took no interest in either product. I then tried Terro ant poison. The ants loved the stuff. They took their fill out the six poison units that came in a pack. Unfortunately, the ants just kept coming in a large column until the bait was gone. They now stream into my garbage disposal, where I dumped some uneaten dog food.
The Grant's I had used had been on the shelf for a few years, so I bought new stakes at Wal-Mart today. Occasionally, an ant will go check out the bait, but they are not interested.
Can someone suggest a brand that is likely to work?
