An organic fire ant killer is a non-toxic substance or method utilized to eradicate fire ants. Organic pesticides include hot water and diatomaceous earth. Hot water poured onto the mounds helps to eliminate the ants and prevent future nesting. Diatomaceous earth kills bugs and is non-toxic to humans and animals.
One of the most effective organic methods of eliminating fire ants is to bucket the entire colony. Bucketing consists of shoveling the ant mounds into moderately sized buckets and sprinkling the soil with baby powder or cornstarch. Fire ants tend to be repelled by powdery substances, and this helps to prevent them from traveling and building additional nests.
