I tried a rototiller.I'll have to try some of that I'm tired of constantly being stung up by these little devils
Poured hot grease from a frying pan on them.
Caused them to move a little ways away and start another mound is all.
Mounds for fire ants here can get three or more feet across and a foot or more high. Or not be noticeable till you stand on them. Which I've done bare legged in moccasins.
With a stake and tether so something doesn't carry it away , fire ant hills are good for cleaning skulls on. So the rumor goes.
