Siesta Insecticide Fire Ant Bait, with the active ingredient metaflumizone, delivers fast and long-lasting control of native and imported fire ants.
Metaflumizone belongs to the IRAC (Insecticide Resistance Action Committee) Mode of Action Chemical Group, 22B.
This fast-acting insecticide works through ant ingestion with limited contact activity. Feeding cessation begins quickly—within 15 minutes to 12 hours of ant recruitment. Insects die within 72 hours.
Siesta Insecticide Fire Ant Bait is the only sodium blocker insecticide (SCBI) that does not require metabolism for bioactivation. It acts on the insect’s nervous system, where it blocks the voltage-dependent sodium neuron channel. As a result, these neurons are inactivated, causing the ant to enter a state described as “relaxed paralysis,” or a siesta.
Keys to Success
Siesta Insecticide Fire Ant Bait is best applied as a broadcast treatment where foraging ants and mounds that remain hidden or unnoticed receive coverage. Broadcast treatments can be applied to the area using a hand spreader, backpack or push-type spreader. For larger acreage, spreaders can be attached to an ATV, truck or tractor to allow for even coverage. Calibrate spreader prior to use to apply a rate of 1.0–1.5 lb./A.
Always read and follow label directions.
