Many sources say Diatomaceous Earth works on fire ants especially if you can dust it on them, or on their pathways. But, if you are trying to eliminate “ant colonies within treated mounds”… you should use Diatomaceous Earth ALONG WITH other methods or ingredients. For example, D.E. is used with pyrethrins to possibly help enhance penetration of this botanical insecticide into the insect’s bodies.
“A few active ingredients used in fire ant control products are commonly referred to as “organic” (e.g. boric acid, pyrethrins, rotenone and diatomaceous earth). Diatomaceous earth, a natural silica-based dust, will kill some ants, but is not very effective when the soil is moist and it rarely eliminates ant colonies when used alone.
You can use boiling water (about 3 gallons per mound)… will eliminate about 60% of the mounds treated…Surviving mounds will need to be treated again. Care must be taken not to pour boiling water on grass or other plants.”
“There are not many effective organic treatments. Possibly the best one is to pour 2 to 3 gallons of boiling water on the mound. This can be about 60 percent effective if it is done after a rain and the mound has been freshly re-built…
Another organic treatment method that has fair success is to apply diatomaceous earth to the mound.”
This article (from the U. of Georgia Agricultural & Environmental Sciences) states that Diatomaceous Earth, combined with other ingredients, has been registered for treating ants in vegetable gardens.
“Diatomaceous Earth products are usually applied to ant trails indoors.
D.E. abrades the waxy layer from the insect exoskeleton, causing the insect to dessicate.
However, D.E. does not eliminate the colonies within treated mounds. When D.E. is used as a carrier in formulations of pyrethrins, it may enhance penetration of this botanical insecticide into insect bodies.”
It will help to provide a favorable environment for organisms that kill newly mated fire ant queens, such as: birds, lizards, toads, & dragonflies:
Good Luck! Hope this is helpful.
