Why Do Garages and Sheds Attract Pests?


By Melissa Hoy

Garages and sheds often check off all the things pests look for: shelter, food, and water. Here’s why these areas are such common pest hot spots:

1. Clutter Creates Hiding Spots
Rodents and insects are shy by nature. They look for places where they can stay hidden and feel safe. Piles of boxes, stacks of firewood, unused furniture, or bags of clothing give them the perfect cover to move in and stay out of sight.

2. Limited Human Activity
Unlike kitchens or bedrooms, garages and sheds don’t get used as often. That means pests can build nests, lay eggs, and spread without being disturbed. The less you go in there, the more pests can settle in.

3. Stored Food or Pet Supplies
If you keep birdseed, pet food, or snacks in your garage, it’s like ringing the dinner bell for pests. Mice, ants, and cockroaches can chew through cardboard or plastic to get to food. Even a few crumbs can attract them.

4. Moisture Problems
Garages and sheds aren’t always sealed tightly, which means water can sneak in through cracks, under doors, or from leaky tools and containers. Damp spots are like magnets for pests like silverfish, cockroaches, and termites.

5. Easy Entry Points
Rodents only need a hole the size of a dime to get in. Most garages and sheds have small gaps under doors, between boards, or around vents that go unnoticed—until pests find them.


Common Pests Found in Garages and Sheds

Here are some of the pests you’re most likely to find in these storage areas:

  • Mice and rats: They chew through wires, insulation, and boxes, and they leave behind droppings that can spread disease.
  • Spiders: Most are harmless, but some, like black widows, are venomous and love dark corners.
  • Cockroaches: They hide in tight spaces and are drawn to any food or moisture available.
  • Ants: Especially during warmer months, ants can build nests in walls or under stored items.
  • Silverfish and earwigs: These creepy-crawlies love damp, dark places and can destroy paper, books, and cardboard.
  • Termites: If you’re storing wood, termites might see your shed as a buffet.

How to Keep Pests Out of Your Garage or Shed

While pests love these storage spaces, there are plenty of steps you can take to make them less inviting.

1. Declutter and Organize

Start by going through your storage area. Toss out things you no longer use and organize what’s left in sealed plastic bins instead of cardboard boxes. Keep items off the ground using shelves or hooks to reduce hiding spots.

2. Seal Entry Points

Inspect walls, floors, windows, and doors for cracks or gaps. Use caulk or weather stripping to seal them up. Make sure garage doors close tightly and that there are no gaps underneath.

3. Store Food Properly

Don’t store pet food, birdseed, or pantry items in your garage or shed—especially not in bags or cardboard boxes. If you must store food, use airtight containers made of heavy plastic or metal.

4. Keep It Dry

Fix any leaks, and make sure the space is well-ventilated. Use a dehumidifier or moisture absorber if the area tends to stay damp. Elevate items off the floor to avoid moisture buildup under boxes or furniture.

5. Clean Regularly

Even if you don’t use the space daily, try to sweep, vacuum, or wipe down surfaces at least once a month. This helps you catch signs of pests early—like droppings, nests, or chewed materials.

6. Be Cautious with Firewood and Cardboard

Don’t stack firewood inside your garage or shed for long periods. If you must store it, keep it elevated and away from the walls. Avoid using cardboard boxes for long-term storage since pests love to nest in or chew them.
