The Q&A Archives: Controlling Red Ants in Garden

Question: We have red ants in our garden, and we wondered if there is a way to get rid, or discourage them in any way without harmfull chemials.

You have a very interesting web-site. All the best from Canada. Keith. :-)))

Answer: Are the ants causing harm in your garden, by protecting aphids on crops? Ants can be helpful in controling some garden pests, but if they're so numerous you get bitten every time you enter the garden, you'll need to take action.
The lowest-impact method of control is to pour gallons of boiling water into the nest itself. Repeat as necessary until the critters are gone.

Probably your surest way to control the red ants is with a boric acid bait. Boric acid is poisonous to all insects, animals and people, but if you follow the label directions carefully, you can easily target the ants and everyone else should be fine! Many garden centers sell boric acid baits, or you can make your own by mixing 1 tablespoon of boric acid with 1/4c of jelly. Put bait inside a paper cup covered by an inverted paper cup, and make a few holes to admit the ants. Place the bait station(s) in the path of the ants; they should take the bait back to the nest, where it will do in the whole colony.
