Sounds interesting and I will give it a try. Making ant bait is too much like cooking—work.
Now if I could find a way to stop the mosquitos from eating me alive. It gets worse as I get older and the bites are more irritating as well.
After you pour a stream all around, use the hose to get it in the ground. If there is still a few around repeat a little further away from the edges and do it extra good around their holes. As you will notice the soap kills the ants. Eventually they will all be gone to somewhere else. I guess they don’t like something in the soap. Dawn or Palmolive in what I use.
What type ants are plaguing you ?
For Argentine ants, the easiest way I’ve found is to just use Terro. It’s a slow kill, but their whole nest is killed in a week.
A faster way, that kills the whole colony & works with most types of ants, is to take a garden hose & squirt the ground by your foundation, patio slabs & side walks. Do this just enough to soak the ground. A minute or so at high volume should do. Then check those areas a few minutes after their flooding. If there’s a nest there, they’ll be evacuating it & carrying their eggs to higher ground. When most of the colony to get out, hit-em with your favorite EPA approved instant kill pesticide (chlordane, DDT, what-ever).
