New Musca-Cide Fly Bait Spray offers adaptable delivery options, including spray-on, paint-on and spot treatments. The spray goes where traditional granular scatter baits cannot, including hard-to-reach areas and vertical surfaces. Just 2 oz. of the water-dilutable formulation provides up to 250 sq. ft. of coverage. The active ingredients, dinotefuran and (Z)-9-tricosene, both attract and kill house flies, offering fast-acting knockdown and results.
