I noticed today that our cats' food bowl had a stream of Thief Ants (Solenopsis molesta) going to it and in it. They were following around the edge of a carpet towards a tiny crack at the bottom of the baseboard on the edge of an interior wall, about 6" from the exterior wall. Not sure if they're nesting in the house or coming in from outside. However, I want to kill the stream coming in - not sure what would be best - Borax-laden food? If so, what kind? Diatomaceous Earth? Lava? Once I kill them/get rid of them, I plan on resealing the baseboards though I know that won't prevent this (as they will find just about any opening, including wall outlets). What's the best way to prevent similar in the future? I am considering some kind of raised food bowl, like: =(, where the stem '=' perhaps has Fluon on it? S. molesta doesn't appear to have difficulty climbing glass, so that won't work.
I'm hoping we know how to kill them intentionally, since we manage to kill them accidentally while raising them all the time!
