Gnavex Bait Blocks
Gnavex Bait Blocks provide powerful, fast-acting rodent control using bromethalin, a highly potent neurotoxicant that delivers a lethal dose to Norway rats, roof rats, house mice, and meadow voles in a single feeding. These bait blocks are engineered for tough infestations, with the first dead rodents often appearing within just two days.
Made for both livestock and poultry production as well as residential use, Gnavex is EPA-registered and built to perform in demanding environments. Each block features multiple gnawing edges that encourage feeding, while a built-in bittering agent helps reduce accidental ingestion. Weather-resistant construction allows use in wet or dry conditions, and the product may be applied in and around man-made structures (within 100 feet).
Packaged in a convenient 4-pound resealable pouch, Gnavex keeps bait fresh, easy to store, and simple to deploy in approved tamper-resistant bait stations. This product replaces CyKill All Weather Bait Blocks while delivering the same trusted performance under the Neogen brand.
