Ant control in lawns.
Controlling fire ants is a two step process.
You can pick up either option the next time you go grocery shopping.
First use a mound treatment like ortho orthene fire ant killer 1 or a fire ant bait like ortho fire ant killer mound bait to kill the nuisance mounds you see in your lawn and landscape beds.
The workers are most active outside the nest scavenging for food in the cooler morning and evening hours.
Killing ants in your lawn with chemicals.
Spot control is the best method for killing ants.
Ant baits are used to eradicate entire ant colonies and are very effective.
Homeowners can get rid of ants in their lawn by sprinkling baby powder where ants are present to eliminate them.
If you do not have baby powder baking soda can work as well.
For larger infestation treat the lawn with liquid insecticides or ant baits.
