According to the “Best Rat Poison” category on Bestcovery.com, the products that rank highest are Neogen Rodenticide, Tomcat, and D-Con. Bestcovery.com evaluates and reviews various household products, including pest control formulas.
The experts at Bestcovery consider Neogen Rodenticide Havoc Mouse and Rat Killer to be an easy and safe product to use. The poison is contained within a sealed package, so the rats must gnaw through the package to get to the granules. The formula is an anticoagulant that kills rats after a single feeding. Like Havoc, D-Con Rat & Mouse Bait Tablets are an effective anticoagulant formula. D-Con pills are not as securely hidden as Havoc, but D-Con products are found in many retail stores. Tomcat Rat Killer II is a nerve toxin encased within a blocking bait station. There is no antidote to nerve toxin, so great care must be taken when handling this product.
