I'm having a really hard time getting rid of little black ants that are everywhere. I'm not too sure on what kind of ant it is, but they're not red like fire ants nor brown like sugar ants. Back home in Louisiana the mounds are built above ground so it's easier to relocate/erradicate them. Here in Arizona, the mound is below ground and it's not always easy to locate. They just started making their way closer to my doors and windows. Any advice on how to repel them or perhaps a natural insecticide I could lay down in the yard would be great! I don't want to spray any harsh pesticides or chemicals because my dogs lay outside in the grass for a few hours a day. Thanks for any advice and help in advance!
