It is not a fast-acting insecticide, but a reduction in live mounds should be seen in about three weeks. The broadcast treatment rate is 1.0 -1.5 pounds of product per acre. It also can be applied as an individual mound treatment. It can only be used for mound treatments, however, since it is not labeled for broadcast application. Control with this toxicant bait is rapid, and mounds should die out in about a week.
Producers can expect about two months of long-term control following treatment.
It is applied as a mound drench. Producers should mix according to label instructions and apply two gallons of solution per mound or at least one quart per six inches of mound diameter. Mounds can be retreated with Sevin in seven days if fire ant activity persists. For additional information about fire ant control, contact an Extension agent in your parish LSU AgCenter office.
