fire ant mound |
For now, I
control fire ants by soaking their mounds with a non-poisonous liquid compost
solution. I don’t claim to be an etymologist, but this safe, homemade solution
works for me – and costs less than 10% of what I’d pay for an advertised
poison. And, if you get the queen, fire ants won't return.
I recommend a
mixture of 40% compost tea, 40% orange oil and 20% liquid horticultural
molasses (mixed thoroughly). Then I mix a half-cup of this mixture with one gallon
of water, and saturate the fire ant mound with it. Pour slowly, making sure it
soaks into the mound, and doesn’t just run off. (I use a stick to quickly break
through the mound’s crust)
This natural solution
doesn’t poison the fire ants (or children or wildlife or pets), it instantly
dissolves the insects’ exoskeletons so they can’t walk, dig or eat. In about
five minutes, there’s no ant activity. A few days later I’ll add beneficial nematodes
to the soil to control fire ants long term.
