Siesta Insecticide Fire Ant Bait

Keep fire ants off your turf.

Fast, effective and affordable.

Product Overview

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.

Siesta is the only sodium blocker insecticide (SCBI) that does not require metabolism for bioactivation. It acts in 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.

The direct effects are that Siesta Insecticide Fire Ant Bait causes the cessation of feeding, increasing levels of immobility, and ultimately, ant death.

Performance Data

Fast Control in Broadcast Applications

Study: J. Cook, Sam Houston State, TX

This study demonstrates the speed of control. It compares the mean number of foraging workers over time (8 hours, 24 hours, 3 days, 7 days, 14 days) for Untreated Control, Siesta™ (0.063% bait at 1.5 lb./A), and Advion® Fire Ant Bait (0.045% bait at 1.5 lb./A). Siesta™ showed a rapid reduction in foraging workers, reaching very low levels by 24 hours and maintaining this control. Advion® also reduced foraging workers but at a slower rate than Siesta™.

Effective Control in Broadcast Applications

Study: L. Greenberg, Univ. of CA, Davis

This study evaluates long-term effectiveness. It compares the mean number of foraging ants over time (Pre-treatment, 7 days, 70 days, 105 days) for Untreated Control, Siesta™ (0.063% bait at 1.5 lb./A), and Amdro® Pro Fire Ant Bait (0.75% bait at 1.5 lb./A). Siesta™ provided significant reduction in ant populations from pre-treatment levels and maintained control throughout the 105-day observation period, performing comparably to Amdro® Pro.

Behavior in Ants

Siesta Insecticide Fire Ant Bait acts primarily through ant ingestion with limited contact activity. Feeding cessation begins quickly, within 15 minutes to 12 hours of ant recruitment of the bait. Insect death normally occurs within 72 hours.

Use Rates

Broadcast: 1.0-1.5 lb./A applied broadcast to the area.

Mound Treatments: 1.0-2.0 oz. (2-4 level tablespoons) around the mound.

Do not apply more than 6.0 lb. of product per acre per year or four applications.

Signal Word

CAUTION

Re-Entry Interval (REI)

None for non-WPS uses. 12 hr. for agricultural uses such as nurseries and sod farms.

Personal Protective Equipment (PPE)

Long-sleeved shirt and long pants, waterproof gloves, shoes plus socks.

General Care and Storage

Keys to Success

Siesta Insecticide Fire Ant Bait is best applied as a broadcast treatment to cover foraging ants and mounds that may remain hidden or unnoticed. Broadcast treatments can be applied using a hand spreader, backpack, or push-type spreader. For larger areas, spreaders can be attached to an ATV, truck, or tractor for even coverage. Calibrate the spreader prior to use to ensure an application rate of 1.0-1.5 lb./A.

Mound Treatments

Retreatment and Rainfall Considerations

Retreatment with Siesta Insecticide Fire Ant Bait is on an as-needed basis and is influenced by environmental conditions and ant/mound populations. Always read and follow all label directions when making reapplication.

If heavy rainfall occurs within 12 hours of application, the bait treatment can be affected. Check ant mounds and foraging ant activity within seven days to determine if the bait resulted in good ant control. If needed, apply a contact insecticide such as Prescription Treatment® brand Cy-Kick® CS to the mounds.
