3 Reasons Mice in Your Outbuilding Is Not Good

Let’s be honest – mice can be kind of cute. When it comes to your property, even the most adorable mouse can cause big trouble, even just in your outbuilding.

If you have spotted a furry rodent tenant or two scurrying around your garage, shed, or outbuilding, it might be tempting to let them stay. After all, it’s not like they’re inside your house, right? Unfortunately, outbuildings are the perfect segue to bigger rodent problems. Here are a few reasons to give those whiskered squatters the old heave-ho.

Problem 1: Mice Don’t Respect Property Lines

You might think you’re doing a good deed to a mouse in need by letting them bunk on your property. Even if your garage is detached or your outbuilding doesn’t seem to be an issue – walls are only minor mouse inconveniences. Once they find warmth and food inside your outbuilding, they’ll start exploring their upgrade options.

Storage sheds, garages, and the like are often just the cozy first stop for rodents packing it in from the cooling temperatures. It’s only a short crawl through a gap to reach your indoor living spaces. What begins as a few mice in the barn can become a full-blown infestation inside your pantry.

Problem 2: They Chew - Everything

Mice have teeth that never stop growing. Like those of elephants, horses, and crocodiles, mice hypsodont teeth are built for chewing – and chew they do! Their gnawing is indiscriminate. They emphatically chew on cardboard boxes, wires, insulation, furniture, stored keepsakes – absolutely everything! So yes, their sweet faces can do some serious destruction with those tiny teeth.

Problem 3: Mice Bring Uninvited Friends and Odors

Even if you never see them, you will eventually smell them. Mice leave droppings, urine trails, and an unmistakable musty odor that clings to everything. It’s not uncommon for homeowners with an unknown mouse infestation to think the odor is coming from other sources, like elevated moisture, mold, or mildew.

But that’s not all! They can also carry fleas, ticks, and other mites that might migrate into your yard or home. Rodents are a big culprit of transmitting these unwanted bugs onto your property in St. Louis Metro East. What seems like a small wildlife issue in your shed can easily turn into a pest problem across your entire property!
