Description:This image depicts a number of different grain bait formulations of cholecalciferol (Vitamin D3), which is a relatively newly created rodenticide, has been registered for use in New Mexico, and holds great promise for the control of field rodents involved in plague epizootics.
When extremely large populations of rodents are in very close proximity to humans, flea control alone may not be adequate. Flea control should be considered an emergency, or short-term action. It may alleviate or postpone the problem, but does not eliminate it. Carefully designed, and well-executed rodenticidal control programs may have longer-term effects, but like insecticidal control, must be repetitive. A more lasting effect can sometimes be brought about by altering the environment to deny the rodents harborage and food, particularly in environments already occupied by humans, which had been altered to favor rodents. Each situation must be analyzed to determine if control is feasible or necessary, and which strategies are most appropriate.
