We have a real fire ant issue in my house. We don't use poisons due to 1, hating poisoning things, and 2, we have lots of other animals (including my ants).
Does anyone know a good barrier to put on the sides of formicariums that these girls don't cross? Oil doesn't work, they just say yummy!
I need something that is hopefully easy to obtain and will stop them from attacking/foraging in the other ants nests in here.
Even if just foraging, once they get in they happily go for the throat with the other species.
