The answer to 'how long does fire ant treatment last' is that the effectiveness of fire ant treatment can vary, but typically lasts 3-6 months on average. Fire ant treatments work by either killing the existing fire ant colony or disrupting the colony's ability to function, which prevents the ants from rebuilding and re-infesting the treated area.
The longevity of fire ant treatment depends on several factors, including the type of treatment used, the size and maturity of the fire ant colony, environmental conditions, and how thoroughly the treatment was applied. Professional-grade fire ant treatments tend to last longer than over-the-counter DIY options. To maintain long-term fire ant control, homeowners may need to reapply treatments every few months, especially during peak fire ant season.
