How to Keep Rodents Out of Your Shed and Garage This Winter

Trim Vegetation

Weeds or vegetation popping up around your shed? Right there's your problem. "Rodents like to hide in overgrown plants or piles of wood and debris," cautions Dillard. "To avoid this, trim back vegetation around the shed and eliminate any clutter that could serve as shelter."

Install Barriers

Install door sweeps on outdoor buildings to prevent rodents from sneaking under the door. "Metal thresholds can also deter them from gnawing through," recommends Dillard. "Additionally, a gravel or concrete base under the shed can make it harder for rodents to dig under the structure."

Set Bait Traps or Install Deterrents

"Placing traps or bait stations near entry points or where rodent activity is suspected is a surefire way to keep them out," notes Dillard. Traps like Tomcat Press 'N Set Mouse Trap or even a trap of bait poison like Tomcat® Rat & Mouse Killer are a form of control designed to stop them at the source. If using traps, ensure you also monitor them frequently to dispose of captured rodents or reset traps to restart the cycle.

Rodents are also deterred by products containing essential oils such as peppermint oil, garlic, and cinnamon oil such as Tomcat Rodent Repellent Ready to use. "It’s great to use around the shed's perimeter or near potential entry points," notes Dillard.

She adds, "While not typical for pest control, some homeowners use products that contain predator urine (like fox or coyote)." The strong smell can also help deter these pests.

How can you tell if there are rodents living in your shed?

Whether it's a pair of mice, chipmunks, or an army of rats, look for several signs:

• Check for droppings, which are usually small, dark, and pellet-shaped, indicating recent rodent or mice activity.
• You may also notice gnaw marks on wooden or plastic surfaces, as unwanted visitors have a tendency to chew through materials to create nests or find food.
• Look for chewed wires. If you notice that your ceiling light no longer works, or your lawn mower won't start, nesting animals might be to blame. These animals have sharp teeth and while they might not intend to chew electronics, they're willing to do a lot of damage in order to survive.
• Additionally, look for rodent nests. Ideal nesting materials include shredded paper, fabric, or insulation, which rodents often use to build their homes. You might find them nestled into storage boxes,
• Unusual noises, especially at night, can also be a strong indicator of rodent presence; listen for scratching or scurrying sounds.
• Finally, check for burrows around the shed's foundation or entry points where rodents may have gained access, as these are clear signs of their habitation.
