Rat infestations can be prevented by any of three methods: food source removal, rat shelter removal, rat proofing.
Food Source Removal:
Rats are capable of eating almost anything. It is important to remove all possible food items such as garbage, empty food containers, spilled grain or feed. Keep pet food secure and clean up uneaten food. Keep domestic garbage in containers until disposed of. Properly maintain any garbage pit or compost pile you may have. Do not give rats a chance. Remove any and all possible food sources.
Remove Rat Shelters:
Rats can and will make any object their temporary or permanent home as long as they can crawl underneath. Until a rat can seek out permanent cover, it will use any flat object lying on the ground including tires, planks, square bales, junk, etc. Keep your property clean and tidy.
Buildings with cement foundations and floors, as well as metal siding, help eliminate rat habitat. By elevating farm out-buildings, protecting doorways and windows, using cement floors for sheds, granaries, warehouses and industrial structures, rats can be successfully turned away from potential shelter. Efficient rotation of stored grain or forage bales will also discourage rat activity.
