DISCLAIMER

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 https://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 A&M AgriLife Extension Service, 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.
