Description:
Heptafluthrin 95% TC is a high-performance synthetic pyrethroid insecticide developed primarily for soil and household pest control. It exhibits exceptional vapor activity, which makes it effective even in small doses for controlling a wide range of soil-dwelling and crawling insects. Unlike most pyrethroids, Heptafluthrin has a strong fumigant effect and is designed to act quickly against target pests through both contact and vapor phase.
Heptafluthrin is particularly used in granular insecticide formulations applied to soil for the control of wireworms, root maggots, and other subterranean pests in crops such as corn and sugarcane. Additionally, it has potential for use in household insecticides and pest control for industrial and storage areas due to its volatility and broad-spectrum efficacy.

Applications:
Heptafluthrin 95% TC is used in the manufacture of formulations such as:
-
Granular insecticides (GR) for soil treatment
-
Emulsifiable concentrates (EC)
-
Ready-to-use baits and vaporizing systems
-
Household insecticides and pest repellents
Target Pests:

Household pests: cockroaches, ants, termites, silverfish
-
Storage pests: beetles, weevils
Major Use Areas:
Mode of Action:
Heptafluthrin acts by interfering with the sodium channels in the nerve cells of insects. It prolongs the opening of sodium channels, leading to hyperexcitation, paralysis, and death. Its significant vapor activity allows for knockdown of insects even in enclosed spaces or soil, making it effective through both contact and inhalation.
