I'm wondering...how bad are they?
They are bad, BAD. They are taking over the gulf coast and moving like a wild fire into north LA. And then they are just as hard or harder to get rid of as the fire ants. I'm not even sure it's possible to get rid of them. They compare to the Kudzo vine...
Here is a link regarding fire ants that provide you some help. I put fire ants in the same category as Chinese Tallow Trees. And if you don't have them yet, don't ask. You do not want them either. lol
