Fipronil, the newest active ingredient on the US market, is now available in Maxforce FC bait stations. Fipronil offers the pest control industry a new chemistry with a unique mode of action. Maxforce used this new chemistry to create bait stations that offer both long-term control and faster results than demonstrated by other ant and cockroach bait products. Fipronil is a highly active, broad-spectrum insecticide from the phenyl pyrazole family. Scientists discovered fipronil and identified its insecticidal properties in 1987. Used at low doses, the active ingredient is highly effective against a broad range of insect pests, including ants and roaches. Fipronil's mode of action sets it apart from most commercial insecticides currently on the market. Fipronil disrupts the insect's central nervous system by blocking the passage of chloride ions through the GABA receptor, an inhibitor of the central nervous system. This causes hyperexcitation of contaminated insects' nerves and muscles. While many classes of insecticides affect the central nervous system, no other class has this specific effect. Like hydramethylnon, there is no known resistance to fipronil. Faster Speed of Kill Field test results of Maxforce FC show significantly faster control of German cockroaches, American cockroaches, and Ants. Secondary kill still achieves population elimination, only faster. How Fipronil Works - The Domino EffectTM, Only Faster Fipronil controls target insects with a single feeding. It is effective in the control of roaches and ants because both insects serve as carriers of the active ingredient to harborages and colonies. This new active ingredient-Fipronil- provides a unique mode of action. It works through both ingestion and contact knocking down ants and roaches* that eat or simply touch the bait. Either way, one contaminated roach kills many others where they live or breed. The Domino EffectTM still achieves colony elimination, but with faster visible results. * Contact data based on American Roach Tests. Bait Acceptance The Maxforce FC formulations are simply irresistible to target roaches and ants. Each bait is formulated with a unique blend of inert food ingredients designed to maximize attractiveness for the diverse feeding habits of target ants and cockroaches. Fipronil is non-repellent as well. Roaches and ants have been observed standing on deposits of technical fipronil, with no signs of being repelled. Stability of Maxforce Bait Formulations Maxforce FC bait stations have a shelf life of approximately 2 years in an unopened container. Once they are applied, they will last at least one year or until the bait is consumed. Low Toxicity to Mammals While fipronil is very effective against target insects, it has low toxicity to non-target animals. A summary of toxicological information follows: A summary of toxicological information:

Species	Condition	Effect Level
Rat	Acute oral LD50	97 mg/kg
Rat	Acute dermal LD50	>2000 mg/kg
Rat	Acute inhalation LC50	0.39 - 0.68 mg/l
Rabbit	Acute dermal LD50	354 mg/kg
Rabbit	Skin and eye irritation	Non-irritant
Mouse	Acute oral LD50	95 mg/kg
Guinea Pig	Skin sensitization	Non-sensitizer

Fipronil is not volatile, therefore there are not airborne active ingredients released when using Maxforce FC Bait Stations.
This reduces chemical exposure to applicators, customers and the environment in general.
