Getting rid of ants

[Sarah in SC]

I have used Revolution, might try it again (going to drop a few hundred at the vet this afternoon on supplies). We don't seem to have them in the house (I guess they are all on the dogs, but not so much on the cats).

The yard spray might be a good idea, at least under the house (up on pilings 19 feet) and around the shed they like to get under to stay coo. The yard sn't irrigated but our relative humidity might qualify as irrigation this time of year! I've had house infestations in past years, and used Nylin (sp?) to prevent the eggs from hatching.
Thanks for the ideas....I'm up for trying all of them at this point!

Scientific American must have run out of ideas for their August issue because I think they've been reading these threads.

"Alternatives to organophosphate pesticides (like Dichlorvos) exist, notably pyrethrins, which are used in insect sprays, flea treatments, and shampoos for head lice. These compounds, originally derived from chrysanthemum flowers, alter nerve cell function but in a different way from organophosphates. They are not entirely safe either.
"One better alternative is boric acid, especially when used in bait traps, which draw bugs and keep the chemical contained.
"Fortunately the best ways to control insects in the home do not require any pesticides, just good housekeeping: washing dishes and emptying the garbage daily, sealing food containers, repairing screens, caulking cracks and gaps, and keeping bathrooms and kitchens as dry as possible."

One useless information but interesting anyway. If you draw a line on the concrete using a piece of Chaulk the ants will not cross it.
