  • Inexpensive

Active Ingredient: 0.25% s-methoprene and 0.36% hydramethylnon (i.e. Extinguish® Professional + ProBait®)

Similar Products: Amdro® Pro + Extinguish® Professional hopper blend

Application Rate, Broadcast: 1.5 lbs. per acre

Speed of Control: relatively fast, 2 – 4 weeks

Duration of Control: 2 – 12 months, one application per year is usually sufficient, but depends on reinvasion pressure

Approximate product cost: $10 – $15 per pound or $15 – $20 per acre ($3.50 – $5.00/10,000 sq. ft.)

Best used for: Any situation where relatively fast, inexpensive control is needed

Best season for application: Any time ants are foraging for bait

Sources: Garden centers and agricultural suppliers

Toxicity: very low; may be toxic to animals if very large quantities are consumed

Agricultural Uses: Extinguish® Plus may be applied to grass forage (pastures and rangeland) for the control of fire ants in Texas and other (refer to label) southern states. Use on grass forage (pastures and rangeland) in states other than those listed is unlawful.  See Outdoor Use table on container label for application directions. Do not bale and cut treated pastures and rangelands for 7 days following application. These cutting and baling hay restrictions for pasture and rangeland do not apply when the treated pasture and rangeland is used solely to support COMPANION ANIMALS (e.g., horses, llamas, etc.). Companion animals grazed on treated areas cannot be used for food or feed. Extinguish® Plus may be used on uncultivated, agricultural, non-food crop and non-agricultural land.

Mixing with other products: Generally unnecessary because of the speed of hydramethylnon component.

General Comments: Extinguish® Plus combines the speed of hydramethylnon with the longer duration of control of an IGR product (Extinguish® Professional). It is a good product that will likely give satisfactory results with a yearly maintenance application.
