A safe, inexpensive fire ant killer that you'll need real soon!


As I write this, there is a crust of ice and sleet on the landscape. Birds eat anxiously, and hardly a thought is given to the regular spring happenings. Spring will be here very soon, however. It’ll bring the nice stuff like flowers and warm days. But it will also bring fire ants.

Fire ant mounds erupt in unexpected and inconvenient places each spring. So, many homeowners rush to a store and buy anything that promises to kill fire ants, not realizing that it also damages/kills pets, children and wildlife (including birds). It’s poison!!

Instead, I mix up a natural mixture - one that’s very effective, safe and inexpensive. I make a batch of the ”base” every year or so from ingredients at most hardware stores. The cost is about a tenth of the poisonous commercial stuff.

I suggest a mixture of about 40% compost tea, 30% orange oil and 30% liquid horticultural molasses (mixed thoroughly). You can mix up a batch of this “base” now and keep it ready. When the time comes to eradicate a mound I take half a cup of this mixture, mix with one gallon of water, and saturate the fire ant mound with it. Pour slowly to saturate the mound, and let it soak in – not run off. (I use a stick to quickly break through the mound’s crust.)

This doesn’t poison anything. It instantly dissolves insects’
 exoskeletons. In about 5 minutes there’s no ant activity at all. A few days later, I’ll add beneficial nematodes to the soil to control fire ants long term.

  1. Thanks for the great information. A couple of questions: There are many recipes for "compost tea". How do you make yours? And where do you buy your orange oil?
