Active Ingredient: 0.25% s-methoprene and 0.36% hydramethylnon (i.e. Extinguish® + Amdro)
Similar Products: Extinguish® Plus or Amdro® Pro + Extinguish® hopper blend
Application Rate per mound: 2-5 level tablespoons/mound, apply no more than 2 pounds/acre.
Speed of Control: relatively fast, 1-2 weeks, may see immediate reduced activity around mound.
Duration of Control: 2-12 months, one application per year is usually sufficient, but depends on reinvasion pressure
Approximate Cost: $8-$12 per pound or $12-$18 per acre
Best used for: Any situation where relatively fast, inexpensive control is needed
Best season for application: Any time ants are foraging for bait
Sources: Retail outlets, garden centers and agricultural suppliers
Toxicity: very low; may be toxic to animals if very large quantities are consumed
Agricultural Uses: On grounds surrounding poultry houses (excluding runs and ranges), corrals and other animal holding area. For expanded agriculture uses see the Extinguish® Plus product.
Mixing with other products: Generally unnecessary because of the speed of hydramethylnon component.
General Comments: Amdro® Firestrike® combines the speed of hydramethylnon with the longer duration of control of an IGR product (Extinguish®). It is a good product that will likely give satisfactory results with a yearly maintenance application.

This site is intended to cover only broadcast-applied fire ant control products. Literally dozens of products are available as individual mound treatments. Contact your local Extension Agent or return to http://fireant.tamu.edu for more information on individual mound treatments.
Because of the constantly changing availability of fire ant insecticides, it is virtually impossible to include every product on the market. Mention of a product on this site does not imply an endorsement by Texas Cooperative Extension, the Southern Region IPM Center or any cooperating state. Lack of mention does not imply that the product is not an effective fire ant control product.
