Abstract
In the time that the Pesticides Division of Agriculture Canada has been evaluating rodenticides, it has become apparent that the formulated product's efficacy is dependent on the character of the inert ingredients as well as on the actual active toxicant. The type of food, its level of manufacture, the adhesive-binder, the attractants and preservatives can each affect the efficiency of the active ingredient. Currently, very serious problems have arisen because of the anticoagulant resistance and bait shyness that rodents have developed towards existing products.
