Re: Bill's on fire ants and killing the queen

Thanks to Bill/Janet.  My original post probably contained a question perhaps out the scope here.  But I will ask it anyway: fire ant colonies have propagated since my gardens have been planted.  Maybe a dumb ? but are there herbs / vegetables / flowers that might *deter* said propagation?  It's the worst I've ever seen, even in this part of the country.

Incidently, I poured bleach on top of a couple of mounds; One did not return, one was built back up and running by end of (ant) business day.

Thanks
Camille

Fire ants are relatively easy to kill, but unless the queen is destroyed,
certain of her attendants bury her deep in the earth or whisk her away to
start a new hive when she's threatened.  My employer, USDA's Animal and
Plant Health Inspection Service, has been doing fire-ant research for
decades now, and the silver bullet has not been found.  This is the first
I've heard about the melting scenario.  The most successful toxicants are
impregnated into baits, which the ants nibble on and carry back to the
colony, where more ants can be exposed and die.

Cornmeal is said to kill them by ingestion and explosion when the meal hits
the damp gut of the insect.

About 5 years ago, while I was doing a book with our big fire ant guy Homer
Collins (Gulfport, MS), he told me of a then-new phenomenon that had him
plenty worried.  Fire ant colonies began having *two* queens instead of just
one.  Life insurance for the entomological sector.  Bad news for the Mammalia.

Fire ants have migrated northward and are now often found in the
Norfolk/Virginia Beach area.  A few colonies have been spotted in Maryland,
but the winters are too cold for them to get established (so far, knock on
wood).
