Different Rodenticides

Rodenticides, substances designed to control rodent populations, come in various formulations and classes. However, due to safety concerns for children and pets, these products are restricted from consumer markets and can only be used by licensed Pest Management Professionals (PMP). 

Types of  Rodenticides 

Rodenticides may be broadly classified into two categories: anticoagulants and non-anticoagulants. An anticoagulant is commonly referred to as a blood thinner because it is a chemical that prevents or reduces coagulation of blood, meaning that it prolongs clotting time in affected animals.

Non-anticoagulant rodenticides have distinct modes of action. Bromethalin, for instance, disrupts cellular energy production in the nervous system, requiring a single dose for effectiveness and necessitating a license for purchase. Cholecalciferol, which induces excessive vitamin D production, poses risks to humans and non-target animals if exposed. Zinc phosphide, an inorganic compound, produces phosphine gas in the animal's stomach, causing organ failure. Both cholecalciferol and zinc phosphide are classified as restricted-use products by the U.S. EPA, indicating their potential for adverse effects and requiring certification for application.

Strict adherence to labeling instructions and regulations is essential when using rodenticides. Applicators must maintain proper credentials and wear personal protective equipment as outlined on the pesticide label. All labels and Safety Data Sheets should be kept on file, and pesticides should be used in accordance with federal, state, and local regulations.
