Yates Home Pest Cockroach Killer Gel is a professional grade formulation, specifically designed to kill cockroaches without having any impact on non-target organisms, like mammals. There is a delay in the cockroach dying to allow for transfer to other cockroaches increasing the overall death rate. Yates Home Pest Cockroach Killer Gel comes in an easy-to-use syringe for precise bait placement, with each syringe containing up to 100 baits.
