Fipronil is a broad-spectrum insecticide used in various products (sprays, granules, baits) to control pests like termites, ants, cockroaches, fleas, and ticks by disrupting their central nervous system. It works as a slow-acting, non-repellent poison, allowing affected insects to spread it throughout their colony, leading to effective elimination. While generally safe for humans and pets when used as directed, fipronil is highly toxic to aquatic life and should be kept away from water sources. Applications vary from structural treatments for termites and ants to turf applications and flea/tick pet products.
How Fipronil Works
Targeted Action:
Fipronil binds to insect nerve endings, blocking a specific chloride channel in the nervous system.
Systemic Effect:
This blockage causes hyperexcitation of the nerves, paralyzing the insect and preventing it from performing basic functions.
Slow-Acting & Non-Repellent:
Unlike fast-acting contact poisons, fipronil is slow-acting, allowing infected insects to return to their colonies and spread the poison through physical contact and bait sharing, a process known as the cascading effect.
Common Uses
Termite and Ant Control:
Injected into the soil around foundations or applied as sprays and baits for effective colony elimination.
Cockroach and Flea Control:
Used in baits, sprays, and pet-specific products for residual long-term control.
Other Pests:
Kills spiders, mosquitoes, and wasps by contact with treated surfaces.
Turfgrass:
Applied to lawns, golf courses, and other recreational areas to control pests.
Application Methods
Sprays: Applied to surfaces and perimeter areas to create residual barriers.
Baits: Incorporated into gels and bait stations, which insects ingest or contact.
Granules: Used for turf applications.
Dusts: Injected into wood voids or termite nests.
