Does anyone know how to get rid of ants with boric acid?
I ask because we're having a continuing ant problem in the kitchen and the bathrooms. Usually they're the itty-bitty ants I've heard called water ants, but on occasion I've seen larger models too. When we had an apparent nest inside a potted plant, it was easy to wipe them out with some dish detergent in water, but I can scarcely do that here.
I used the boric acid to great effect with a flea problem we were having earlier this summer, but my attempts at ant control weren't as successful. (I was told to mix it with sugar, get it wet, and soak cotton balls in the mixture. The ant would be drawn to the sugar and killed by the boric acid.) Ant traps also have been ineffective.
Raid and other sprays work on ants where we can see them, but I'm after something the ants can take back to the nests with them and kill the queen, so the whole colony will die. I'd also rather not spray poison around the kitchen.
So, any suggestions?
