Are you having a problem with ant piles in your lawn? If you live here in Florida, it is likely that the nuisance ants are fire ants. These can be more than a nuisance. Fire ants will bite if you disturb the pile and if you have children playing in your yard, you will want to get rid of those piles.
Fire ants are nocturnal. You generally won’t see them unless you repeatedly disturb a pile which you don’t want to do. You won’t get rid of the ants that way and many ideas you may find online won’t take care of the problem either. Pouring boiling water over a pile may kill some of the ants but the rest will move on and may create numerous new ant piles.
The best way to kill ant piles is with a combination of dusts and baits. Ants like to eat protein based or sweet substances so choose baits with a sugary or protein base. Put the baits on the pile. When the ants come out at night, they will take it back to the other ants.
The worker ants will feed the bait to the larvae. The larvae actually work as the food factory for the adult and queen ants so when you use baits, you will be targeting all of the ants.
Your second approach to killing the whole ant pile will be to use a dust. There are many safe yet effective dusts on the market. EcoSMART has a dust that is so safe, it is exempt from EPA regulation. Another safe dust option is something that is Boric Acid based.
Use the dust to cover the ant pile and surrounding areas. When the ants come out at night to take from the bait, they will also be walking through this dust. When the ants groom themselves, they will ingest the dust and die.
By using this two -step approach you will be able to effectively kill the entire ant pile and be sure you have not left any ants behind to start a new colony in your yard.
