Pet Food

Storing pet food in your garage is basically like inviting pests into your home for a delicious snack. But if you must keep pet food in the garage (or even when it’s inside your house), be sure that it is inside a tightly sealed plastic or metal container. Rodents can easily chew through paper or cardboard packaging.

You want to save your favourite books from childhood to give to your kids or grandkids someday, but storing them in the garage isn’t the best solution.

While firewood may be an important year-round staple in your home or backyard, it’s also a magnet for pests that will happily make the jump into the house. Be sure to store firewood at least 6 metres (20 feet) away from the house—that includes the garage—and only bring in as much as is necessary.

Sleeping Bags

It’s tempting to stash sleeping bags with other camping supplies in the garage, but you’ll regret it. Fluctuating temperatures and humidity are not ideal conditions for storing fabric. It can get moldy, and makes an ideal nest for rodents. Instead, store sleeping bags and other fabric items inside your house.

In addition, food attracts pests, which you don’t want anywhere near your home!
