Extinguish Extinguish® Plus Fire Ant Bait 1.5 lb - Dry Dual-Action IGR + Adulticide for Lawns & Pastures

Extinguish® Plus Fire Ant Bait is a dual-action dry bait that combines an adulticide and an insect growth regulator to reduce fire ant colonies and stop new ones from forming.

Fire ants damage turf, injure people and animals, and undermine landscapes and agricultural operations. Extinguish Plus blends two complimentary modes of action — a fast-acting ingredient that reduces foraging workers and an IGR that prevents larvae from maturing — so you get both immediate reduction and longer-term suppression. The dry formulation is easy to apply as a broadcast or spot treatment across a variety of sites, from lawns and parks to pastures and commercial turf areas.

How quickly will I see results after applying Extinguish Plus?

Expect visible reduction in ant activity soon after workers ingest the bait; full colony suppression takes longer because the product also stops immature ants from developing. Initial worker mortality helps reduce stings and visible mounds while the IGR prevents the colony from replenishing its population.

• Worker reduction often begins within 24–72 hours after feeding.
• Colony decline and fewer new mounds typically develop over several weeks.
• Repeated or follow-up applications may be needed in heavy infestations per label directions.

Where can I use this bait safely and effectively?

Extinguish Plus is labeled for many outdoor and some indoor settings and is suitable for use around livestock grazing areas, turf, ornamental plantings, and non-fruit-bearing trees. Follow the product label for site-specific instructions and any restrictions to protect sensitive areas.

• Approved on residential turf, sports fields, parks, and sod farms.
• Can be used where cattle and horses graze with no withdrawal period required.
• Suitable for commercial nurseries and non-fruit-bearing trees and saplings.

How should I apply Extinguish Plus for best performance?

The dry bait can be broadcast evenly over an infested area or applied directly to individual mounds as a spot treatment. Proper application rate, timing, and bait placement increase attractiveness to ants and improve transfer through the colony — always consult the label for precise mixing and application directions.

• Broadcast for area-wide coverage on lawns and pastures.
• Spot-treat individual mounds for targeted control and faster mound reduction.
• Apply when ants are actively foraging and weather is dry for best uptake.

What are the active ingredients and how do they work together?

Extinguish Plus combines an adulticide (hydramethylnon) with an insect growth regulator (S)-methoprene to attack both adult foragers and immature stages. This two-pronged approach reduces current foragers quickly while preventing larvae from maturing into new workers, helping to collapse colonies over time.

• Hydramethylnon targets foraging adults to quickly reduce visible activity.
• (S)-Methoprene interferes with development, stopping new workers from emerging.
• Together they reduce existing colonies and limit future colony growth.

Who is this for: Extinguish Plus is intended for homeowners, grounds managers, turf professionals, ranchers, and nursery operators who need a reliable fire ant bait for residential lawns, commercial turf, pastures, and other managed landscapes. If you need a dry, easy-to-handle product that offers both immediate reduction and longer-term suppression, this bait is designed to fit into integrated pest management programs — always read and follow the product label for safe, effective use.
