Now there is a non-repellent termiticide that provides excellent control of termites yet has minimal impact on the environment. The team of scientists at DuPont has developed another new class of chemistry with this latest innovation, providing high-performing termite control and soil residual for ongoing structural protection. DuPont Altriset, the first soil-applied liquid termiticide launched in almost a decade, is in a class of chemistry with a mode of action like no other termite control product. Laboratory and field study results prove Altriset halts termite feeding within hours while providing termite elimination for critical long-term structural protection. Plus, Altriset offers an excellent toxicological and environmental profile. In addition to requiring no signal word on the label, DuPont Altriset is the first and only liquid termiticide to be classified as reduced-risk under the U.S. EPA reduced-risk program.

Studies have proven that DuPont Altriset is highly effective against termites, and even halts feeding in hours. Laboratory tests have shown as termites tunnel through the treated zone, they quickly acquire a lethal dose of Altriset. However, these termites will continue to crawl, groom and clean for extended periods after exposure.

Once affected by Altriset, termites will begin to exhibit increased aggregation, enhanced grooming and contact with other colony members for hours. Affected termites will become more lethargic and show signs of muscle paralysis; decreased coordination and mortality will ultimately occur within several days. The delayed mortality and increased colony interaction are key reasons why Altriset is so effective.

Altriset is the first termiticide product featuring an active ingredient from the anthranilic diamide class of chemistry. This class was inspired by research into the insecticidal properties of a natural substance found in the bark of trees and shrubs of the genus Ryania. Calteryx, the active ingredient in Altriset, is a synthetic compound that affects the ryanodine receptors in the insect muscle fiber. These receptors regulate the flow of calcium into the cell cytoplasm to control muscle contraction. Altriset binds to the ryanodine receptor and causes it to remain open, resulting in a depletion of calcium ions that disrupts muscle contraction. Altriset was designed to target the ryanodine receptors of specific insects such as termites.
