Siesta® Insecticide Fire Ant Bait    

Fast, effective, and affordable

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.

  • Best applied at first sign of fire ant activity
  • Best applied in temperatures above 60°F, when ants are actively foraging
  • Best applied in early morning (no dew) or late in the afternoon
  • DO NOT water in granules after application
  • DO NOT apply when the ground is saturated with water or when heavy rains are expected within 12 hours of treatment
  • If treated areas need to be irrigated, then wait at least 12 hours following treatment

Always read and follow label directions.
