Rats and mice cause significant damage to stored grain, equipment wiring, and buildings while contaminating feed and spreading disease. Fall is the peak season for rodent invasion as cooler temperatures drive them into barns and grain storage. A combination of exclusion, trapping, and baiting provides effective long-term control.
The most durable rodent control strategy is preventing entry in the first place. Mice can squeeze through openings as small as 1/4 inch, and rats through 1/2 inch gaps. Seal foundation cracks, gaps around doors, and openings where utilities enter buildings with steel wool, metal flashing, or concrete.
Place tamper-resistant bait stations every 50–100 feet along exterior walls of buildings, near doors, and along known travel routes. Use second-generation anticoagulant baits for persistent infestations, and always secure bait inside stations to protect non-target animals and children.
Snap traps are effective for mice and provide immediate confirmation of catches. Place traps perpendicular to walls with the trigger facing the wall. Peanut butter is a reliable and inexpensive bait.
Grain bins are prime rodent targets. Maintain a clean perimeter of at least 3 feet around each bin, free of spilled grain and vegetation. Seal all entry points including aeration duct openings, ladder access doors, and foundation joints. Install rodent guards on bin legs where applicable.
Barn cats provide supplemental control but should not be relied upon as the sole method. A well-managed integrated approach combining exclusion, sanitation, trapping, and baiting delivers the most consistent results.
