Bayer Environmental Science has introduced Maxforce FC Select Roach Killer Bait Gel. The new roach gel formulation attracts and kills finicky, aberrant feeding cockroaches, as well as normal, non-bait-averse strains, the company reports. With the active ingredient fipronil, Maxforce FC Select kills cockroaches by ingestion, contact and the Domino Effect, a delayed killing action that enables one contaminated roach to kill many others where they live and breed. Available through authorized distributors nationwide, Maxforce FC Select comes in 30-gram reservoirs designed for use with the Maxforce Bait Injector. The product comes with four reservoirs per box and five boxes per case.
