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.

Oily rags

Never store oil-soaked rags in your garage. Spontaneous combustion (and a devastating fire) can occur when oily rags are stored where the internal heat that is generated isn’t allowed to escape. Tossing these dirty rags is one of the 10 ways you can make your home safer.

You want to save your favorite books from childhood to give to your kids or grandkids someday, but storing them in the garage isn't the best solution. Silverfish are insects that thrive in dark, damp environments such as garages, basements, and crawl spaces and the bugs love to feast on starchy substances, such as the glue that binds books.

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. So store firewood at least 20 feet away from the house—that includes the garage—and only bring in as much as is necessary.

Sleeping bags


Fluctuating temperatures and humidity are not ideal conditions for storing fabric. It can get moldy, and rodents love to chew it. It’s tempting to stash sleeping bags with other non-fabric camping supplies in the garage, but don’t do it! Store sleeping bags, clothes, and other fabric items inside your house.

Extreme heat and extreme cold can alter paint formulas. So if the temperature in your garage is a rollercoaster throughout the year, it’s not an ideal place for storing your leftover paint. Check the paint can label for recommended storage temperatures. But if your paint happens to freeze during the winter, it’s not necessarily ruined. Make sure that you store it upside down, too. Rethink how you keep these household items—you're probably better off storing them upside down

Your child's favorite toys—especially stuffed animals and other plush toys—should be stored in an area other than the garage. Dust mites, other insects and even mice may have their way with the toys if given the chance. If you must store toys in the garage, make sure they are secured in airtight containers. Check out these 12 awesome ideas for storing toys.
