If you decide to treat fire ants yourself, you should:

survey your property or worksite and determine the level of infestation—not all fire ant nests are visible above the ground
report the fire ants by lodging a suspect ant report online or phone 13 25 23
review the list of APVMA-approved baits and choose the one best suited to your situation.

It's important to note baits need to be consumed by fire ants to be effective. To increase the chances of success you should:

always read the product label and/or permit, and follow the directions
apply
- during fire ant treatment season—September to June, and during the coolest time of the day. Fire ants forage less during winter months and in high summer temperatures
- to dry ground and more than 24 hours before forecast rain
- multiple treatments, and within the time period stipulated on the product label
keep children, pets and water away from the treated area for up to 48 hours to give the treatment a chance to work.
