Neogen Corporation CyKill Rat and Mouse Poison

No, you do not need to unwrap them. The blocks come in pouches designed for rodents to chew through directly, which keeps the bait fresh and prevents you from having to handle the poison.

CyKill is a fast-acting formulation that uses a potent neurotoxicant. Because it is designed to deliver a lethal dose in a single feeding, you should see results much faster than with traditional anticoagulant baits.

No, this product is not safe for pets or children. It contains Bromethalin, a toxic ingredient, so it must be placed in areas that are strictly inaccessible to non-target animals and children, preferably inside tamper-resistant bait stations.

Yes, these blocks are suitable for both indoor and outdoor use. However, when using them outdoors, it is best practice to place them inside a secure bait station to protect the bait from weather and prevent accidental consumption by wildlife or pets.

Unlike some older rodenticides, there is no known resistance to the active ingredient in CyKill. Its neurotoxicant formulation remains effective even against rodent populations that may have become immune to other common poisons.

Rodents are naturally inclined to gnaw on edges. The block's shape encourages them to start feeding immediately, which helps ensure they consume a lethal dose quickly rather than nibbling at the bait without finishing it.
