I have a raised vegetable garden and realized today that I have fire ants in a corner. I read online to use boiling water, I did that just now but I’m not sure it got them all. I was cautious not to get to the roots of the plant (young zucchini plant)

Any other remedies if this doesn’t work


Ants are in the closest left corner of the pic

Diatomaceous earth is worth a try.

Keep the garden soil at a proper humidity and the ants will go elsewhere.

Fire ants are a scourge in raised beds,I have a constant problem with them.
Diatomaceous earth doesn’t work.
I use Monterey LG6135 Garden Insect Spray with Spinosad ,order from Amazon.
Mix 2oz.concentrate in 1 gal. water and drench mound.
(Wish I knew how to do links)

Since it's a vegetable garden the 1st thing is get them out of there to use a real poison.

To make them move, place a slice of onion on the mound.

Tomorrow they will be in a different location. Keep moving them till they get in the lawn and then you can kill them with the usual fire ant poisons.

Try it, you'll be surprised.

I did this with liberally stirring baking soda in their mounds. It supposedly messes with ph enough that they head for greener pastures.

No source to link, been a while, but I think it centered around impacting their birth cycle. It worked for me but took a couple times to convince them I wasn't going to stop.

Instant grits. Not a ton of them though and do not water.

Wait until the mound less than damp, sprinkle a small amount, like tsp. Disturb the mound and get the ants to get bring the grits into their home. Wait a day or so then return to watering normally.

Used the method in my organic garden and it always worked despite everyone saying it doesn't.

boiling water works but you have to poke a deep hole into the mound as deep as you can first, then pour the water down the hole. if you can kill the queen the rest of the ants will bounce

Even simpler. Destroying/damaging the mound daily works pretty well. Long stick or a golf club. Stab mound and tear it apart with club. Of course quickly before they make it to your feet or up the stick.

The bastards will rebuild for a day or two but eventually they’ll stop and move the nest.

Hell try the onion slice or the baking soda. But each time frick up the nest. They’ll move.

Just listed to a Joe Gardener Podcast on this. He actually discussed the grits/cornmeal method with a expert in fire ant control, and the guy said NOT to do that. There is actually some kind of bait that should be applied with it that will actually kill the ants.

Otherwise, all you are doing is feeding them.

Best $4 bucks I ever spent. WalMart and Lowe's.

Works on non fire ants, too.

Yep. Have heard many experts say it won't work. Can only say that I used it as an effective method for years on my organic garden.

If you spray for other pest stir them up and spray them down at the same time. I spray with a 3 combo mix it kills everything that crawls and all vegetables safe to eat in a week at the longest.

I’ve also had good results with Amdro in and around vegetable beds. In the lawn proper, bifenthrin. When I began treating treating for lawn insects or fleas on a regular basis, fire ants issues largely disappeared.

I use Sevin Insect Killer Lawn Granules. Disturb the mound a little bit, but don't cave it in. Pour some of granules all over the mound then water it in. Enough to wash some of the poison into the cracks of the mound that you made when you disturbed it. Come back an hour later and they should all be dead.
