That is a good question. Maybe Amdro for ants. I know it works on fire ants. That would suck having that stuff all over your deck.
Here is a true story. Years ago, I took my nephew to the movies and it started raining very, very hard and we had to take all kinds of side roads to get home without getting my mustang stuck in the standing water.
I found out a week later that he had some candy and left it in the car and I could not smell it but one day I had a lot of ants in my car. I got the raid and and roach spray and killed a lot of them but there were like millions of them.
I could not figure out what to do so I got some of the Amdro and killer and put it in the car and left the windows up for a couple days. That stuff killed the ants but I had to drive with the windows down for like a week, that stuff is strong.
