The influence of attractants and repellents on the feeding behaviour of Rattus norvegicus


Poison baits are extensively used for commensal rodent control; considerable folklore exists regarding the use of additives to induce rodents to come to and eat poison baits. This paper describes a rational evaluation of attractants and the influence of different odours in inducing Rattus norvegicus to feed at given locations. The influence of certain repellents was also examined. Tests consisted of attempts to induce rats to feed at non-preferred sites or to repel them from preferred sites. Place preference was the dominant factor in feeding by rats, and odours failed to Influence feeding activity significantly.
