Maxforce Gel (a.i. Fipronil) (previously contained Hydramethylnon): This is the finest roach bait on the market, is used in homes and businesses, and is labeled for restaurants and commercial food handling areas. Maxforce Gel will kill German Roaches, Brown Banded Roaches, Smoky Brown Roaches, Oriental Roaches and American Roaches. The unique action of Fipronil (the active ingredient in Maxforce Gel) makes it an ideal active ingredient for killing roaches. After consuming a lethal dose of bait, cockroaches return to their harborage where they excrete feces containing Fipronil. As other cockroaches consume the contaminated feces, they too receive a lethal dose. When the roaches die, other roaches may consume their carcass and die as well. Tests have documented that this can result in one cockroach causing the death of up to 44 other cockroaches. Our customers have reported seeing thousands of roaches die from one application of Maxforce Gel. This professional roach bait is practically non-toxic to humans and domestic animals by ingestion. For example, a 35 pound dog would have to consume the contents of 14 syringes of Maxforce to receive a lethal dose. When ordering, remember that one syringe of Maxforce Gel will yield about 200 bait placements, or enough to thoroughly treat an average kitchen and two bathrooms. Tip: To increase the appetite of the roaches, spray the areas to be baited with Flea Fix IGR. This drives the roaches to "pig out" on your roach bait, killing more roaches faster!
