Fire Ant Treatment: Individual Mounds with Contact Insecticides

Last Updated: March 11, 2010

In addition to baits, mound treatment insecticides are formulated as dusts, liquids, granules and aerosols. Their effectiveness depends on proper application. Contact insecticides must contact ants to work and should be applied during times of the year (and times of the day) when ants are close to the mound surface. It is also important not to disturb the mound during treatment if the product label so directs. Individual mound treatments selectively eliminate only the ant colonies treated to help preserve desirable native and competitor ant species. However, repeated treatments may be necessary for persistent mounds or nests that are not initially visible.
