Stashing items in the garage feels like a smart space-saving hack, but unchecked temperature swings, humidity, and pest access can turn that storage into a liability. Home experts pinpoint 11 everyday things that belong elsewhere—immediately—to prevent fire risks, irreversible damage, and infestations.
Garages are the go-to catchall for everything from holiday decor to tools. Yet unlike the climate-controlled spaces inside your home, garages endure freezing winters and scorching summers without mitigation. That variability, combined with often-inadequate sealing against pests, creates a perfect storm for degraded possessions and serious safety hazards. According to the Good Housekeeping Institute’s Home Improvement and Outdoor Lab, these conditions make the garage unsuitable for a wide range of household items[1].
The 11 Items to Move Out of Your Garage Now
Paint
Even if your paint can is sealed tightly, garage temperature swings can ruin its consistency. Cold may cause separation, while heat can dry it out completely. “Paint shouldn’t go there, because temperature swings can degrade it,” says Dan DiClerico, director of the Home Improvement and Outdoor Lab at the Good Housekeeping Institute[2]. Store leftover paint in a basement or utility closet with stable, moderate temperatures.
Firewood
While a garage shields firewood from rain, it introduces other risks. Insects and rodents often hitchhike inside on logs, and without proper airflow, mold and mildew can develop. Always stack firewood outside, elevated off the ground and covered only on top.
Gasoline and Propane Tanks
These flammables are a major fire hazard in garages. “Gasoline is best kept in an outdoor shed,” DiClerico advises. “Garages often have equipment with pilot lights, like a water heater. Vapors from stored fuel could react with the open flame and cause an explosion.” Never store gasoline inside your home either; a detached, ventilated shed is safest.
Electronics
From old laptops to televisions, electronics are vulnerable to condensation and extreme temperatures. Cold can crack screens and damage batteries, while heat shortens component lifespans. Keep all electronics in a dry, temperature-stable indoor space.
Garbage
Keeping trash bins in the garage attracts rodents and insects. “Mice are known to nest under car hoods, especially in colder months, when the engine keeps them warm,” DiClerico warns. Store garbage outside in sealed containers, and bring bins to the curb frequently.
Books, Documents, and Paper
Paper readily absorbs moisture, leading to warped pages, ink bleed, and mold growth. Important records, photos, and books should live indoors in a dry area, preferably in archival-safe storage.
Pet Food
Open bags of pet food are an open invitation for rodents and insects. Even unopened bags can be compromised by humidity. Store all pet food inside the house in airtight containers, ideally in a pantry.
Clothing and Linens
Garages are a haven for moths and carpet beetles that will eat through natural fibers. Humidity also promotes mold and musty odors that transfer to fabrics. Keep off-season clothing and bedding in sealed containers inside your home.
Photos and Artwork
Physical photos and original art are irreplaceable. They are highly susceptible to pests, moisture, and temperature damage, which can cause fading, warping, and mold. Store these items in a climate-controlled indoor environment, preferably in acid-free sleeves or frames.
All Food (Including Canned Goods)
Beyond pet food, human food attracts pests. Canned goods are not immune; extreme cold can cause seals to break, while heat may accelerate spoilage. Keep all food in your kitchen or pantry, where temperatures are consistent and pest access is controlled.
Oily Rags
After a car tune-up or staining project, never leave oily rags piled in the garage. “The oxidation process can result in temperatures that are high enough for the oil to spontaneously combust, causing the risk of serious fire,” DiClerico explains. Hang oily rags flat to dry outdoors or dispose of them in a metal container with a tight lid.
By removing these 11 items from your garage, you eliminate preventable fire hazards, stop pest infestations at the source, and protect your belongings from environmental damage. The garage remains a useful space for tools, vehicles, and durable storage—when you keep the wrong items out of it.
