The Texas State something-or-other (department of agriculture?) used to give us five pound bags of fire ant bait. It seemed to work ok. So did soaking the ant bed with kerosene and lighting it up...
Lately I just use a quart sprayer bottle with a couple of "glugs" of Diazinone in it. That seems to disagree with them too...
Well said.
It's time to introduce aardvarks to Europe.
Good Gal. A problem in Europe always needs an American solution! :-)
