Garages collect things: bags of seed, boxes of holiday decorations, old paint, bikes, a spare refrigerator. To a mouse, that clutter is a maze with a pantry attached. We cannot say that clutter causes infestations at any one address, but we do see the pattern: food and cover in a quiet room make a good home.
Food first.
Remove or contain anything edible. That includes pet food, bird seed, grass seed, fertilizer with organic content and even bags of charcoal that have been spilled. Metal cans and thick plastic bins with snap lids make good storage.
- Store kibble and birdseed in tight metal tins or rigid tubs.
- Store recycling in a closed bin after rinsing.
- Wipe up any spills right away.
- Take trash out regularly, and use bins with tight lids.
- Do not leave open food in a spare refrigerator or freezer.
Shelves, bins and floors.
Raise stored items off the floor, ideally on open metal shelving, and leave a gap against the wall. Replace cardboard with lidded plastic bins. Hang bikes and ladders on wall hooks. A clear floor lets you see droppings early.
| Item. | Better storage. | Why. |
|---|---|---|
| Holiday decorations. | Lidded plastic bins. | Cardboard is nesting material. |
| Bird seed. | Metal can with lid. | Plastic alone can be chewed. |
| Old rags and blankets. | Sealed bins or discard. | Soft bedding. |
| Firewood. | Rack outside, away from walls. | Cover for burrowing animals. |
| Paper and magazines. | Recycle promptly. | Easy to shred. |
The building itself.
Check the garage door seal and the bottom corners for daylight. A gap of a quarter inch is enough for a mouse. Look at pipe and wire openings, the seam where the slab meets the wall and any vents. Seal small gaps with metal mesh and sealant, not foam alone. The garage page explains the work.
A quarterly routine.
Four times a year, clear a section of the garage and look. Check corners, under shelves and behind appliances. Look for droppings, gnawing or nesting. A flashlight and ten minutes tell you more than guessing.
- Spring: check for winter damage and reopen vents.
- Summer: clear clutter and keep doors closed in the evening.
- Autumn: seal gaps before cold nights.
- Winter: look for fresh signs after storms.
One more habit pays off: rotate stock. Old bags of seed, forgotten cans and expired pantry overflow sit untouched for months, and an untouched pile is exactly where a mouse can feed unseen. Write purchase dates on lids with a marker, use the oldest first and discard anything stale, so every shelf stays clear of long-term hiding spots and unnoticed food.
If it is the middle of the night, call anyway.
(888) 686-4821Doors, lights and habits.
A door that stays open invites animals. Close it at dusk, and consider a motion light, since rodents avoid exposure. Sweep the floor, keep a lid on the trash and avoid piling boxes against walls.
If you already see droppings, do the wet cleanup first and then call. Photograph the area before and after, and write down the date, because a fresh pile reappearing within a week tells the technician that an entrance is still open and in regular use. Seal and clear after a technician confirms the animal is gone. See our mouse page for the process.
Before you call: a safer way to tidy droppings.
Come back to this list whenever pellets, urine stains or torn bedding appear indoors.
- Even a dust mop kicks old pellets airborne, so no dry implement should begin the work.
- Fresh air does a share of the work, so let the space breathe with nobody in it.
- Rubber, latex or vinyl gloves go on before you touch anything stained, and hand washing finishes the job.
- Contact time matters, so the CDC wants the spray to soak for several minutes before anyone wipes.
- Knot the bag before you carry it, and walk it directly to the outdoor trash.
- Mention the rodent contact to your doctor if illness appears within a few weeks.
Look up the official wording.
