ClariFly Larvicide


Four Central Life Sciences pending applications have been registered with EPA, leading the way for the expansion of the ClariFly Larvicide line. Previously only available in dry feeds, liquid supplements, premixes and custom blends, ClariFly Larvicide now will be available in blocks and tubs. The company’s feed manufacturing partners will introduce the products under their own brands in coming months. The recent EPA registrations also marks the first time the products have been registered as multi-species products that can be offered to cattle and horses.

The four new ClariFly Larvicide end-use registrations for use in blocks and tubs contain the active ingredient diflubenzuron at concentrations between 0.01 percent and 0.08 percent with the concentration dependent on how much the animal is expected to consume daily – whether that is 2 ounces or 1½ pounds. ClariFly Larvicide is a feed supplement that prevents adult house flies, stable flies, face flies and horn flies from developing in and emerging from the manure of treated cattle and prevents adult house flies and stable flies from developing in and emerging from the manure of treated horses. ClariFly works by interrupting the fly’s life cycle, rather than through direct toxicity, and it does so with no impact on the animal consuming it, Central Life Sciences says.
