I’ve never seen these things. They’re regular fire-ant length, but have fat black butts with a little stinger on the end which they carry high. They’re slow and go single-file and not too organized.
My neighbor is a Vietnamese electrical engineer mega-gardener who imports lots of exotics so these ants probably ain’t from around here......
I don’t think I’ve ever seen anything like that here. I also use Ortho fire ant powder in the yard. Kills them in less than one hour, but stinks like heck. We’ve had hardly any wood ants the past two years.
One other thing while on the subject of pest critters. This place sells professional pest control products and will ship most products to most states. I have done business with them for years. It’s a good site to bookmark for future reference.
Aren’t those just regular red ants? Are they on the big side?
