Droppings in the garage
- Along the walls and under shelves
- Near pet food, seed and recycling
- Fresh ones are dark and soft
Fresh droppings tell us where they travel and roughly how many there are. That's where the traps go.

How do you get rid of rodents in a Summit garage or basement?
Garage and basement rodent control in Summit, NJ works best as three steps: find every gap at the bottom of the house, remove the mice or rats already inside, and seal those gaps with materials rodents can't chew. Traps alone rarely end it, because new mice keep using the same openings under the garage door, around pipes and along the sill. Silver Bullet Pest Control serves Summit by appointment from our Garfield base; mouse service includes 90 days of coverage with unlimited free service calls. Call or text 973-510-2585.
Why Summit garages and basements get rodents first
Mice and rats rarely start in the kitchen. They come in at ground level and work their way up, so the garage and basement are usually where the first droppings show up. In Summit that pattern is easy to see:
- Older homes on hilly lots. A lot of Summit houses are decades old, with stone or block foundations, basement windows and sill plates that have settled and opened small gaps over time. A sloped lot can also leave part of the foundation more exposed on one side.
- Detached and tuck-under garages. Detached garages often have worn door seals and an open gap where the slab meets the wall. Tuck-under garages sit right under living space, so mice that get into the garage are one wall away from the house.
- Trees, gardens and wooded edges. Leaf piles, ivy, stone walls and firewood give rodents cover right up against the house.
- Things stored in boxes. Bird seed, grass seed, dog food, recycling and cardboard boxes in the garage are food and nesting material in one place.
When the nights get cold in fall, mice look for warm, quiet spaces. A basement next to a boiler or a garage full of boxes is exactly that.
Mice or rats in the garage? How to tell
What you find in the garage or basement usually tells us which rodent it is:
| What you see | House mice | Norway rats |
|---|---|---|
| Droppings | Small and pointed, about the size of a grain of rice | Larger and blunt, about raisin-sized or bigger |
| Damage | Shredded paper, chewed seed bags, nests in boxes and insulation | Gnawed wood, chewed plastic bins, bigger holes |
| Where | Shelves, storage boxes, behind the water heater, in the ceiling | Along the floor and walls, near the garage door, under stairs |
| Outside | Usually nothing obvious | Burrows by the foundation, under the deck or along the driveway |
| Gap they need | About the width of a pencil | About the width of a quarter |
Don't sweep or vacuum droppings dry. Put on gloves, spray them with a disinfectant, wait a few minutes, then wipe them up. Not sure what you found? Our mice and rat questions page covers the common ones.
Where rodents get into garages and basements
🚪
Garage door
A worn bottom seal or crushed corners leave gaps a mouse walks right under. Side doors with no sweep are just as bad.
🧱
Sill and foundation
The joint where the wood sill sits on the foundation, plus cracks and old basement windows.
🔧
Pipes and wires
Gaps around gas lines, water lines, electric and cable entries, and the AC line set.
🌬️
Vents
Dryer vents with broken flaps, old exhaust fans, and crawl space vents with torn screens.
Mice also climb. Gaps at the top of the foundation and around a garage's roof line count too. More about this in our guide on how to keep mice out of your garage.
Our garage and basement rodent control process
1
Inspect from the outside in
We walk the foundation, garage door, side doors, vents and utility lines, then the inside of the garage and basement: shelves, sill, ceiling, behind the water heater and the boiler.
2
Remove what's inside
Traps placed along the walls rodents actually travel, out of reach of kids and pets. Locked, tamper-resistant stations outside where they make sense.
3
Seal the openings
Gaps closed with materials rodents can't chew through, plus door sweeps and garage door seal fixes where needed.
4
Check back
We come back to check traps and activity and adjust. Mouse service includes 90 days of coverage with unlimited free service calls.
Sealing is the part that keeps them out. See our page on rodent proofing and exclusion for how we do it.
What we look for in a Summit garage or basement
Gaps at pipes and lines
- Gas, water and electric entries
- AC line set and cable wires
- Old holes from removed pipes
Openings where lines come through the foundation are some of the most common ways in, and they're easy to miss.
Nests in insulation
- Insulation pulled out between joists
- Shredded paper or fabric
- Smell in one corner
Mice nest in the basement ceiling above the sill. If it spreads up the walls, it can reach the attic too.
Chewed car wires and stored items
One of the most expensive signs of rodents in a garage isn't in the house at all. Mice and rats sometimes nest in the engine bay of a car that sits for a while, and they can chew wiring and stuff the air filter box with nesting material. A car you only drive on weekends, or one parked in the garage all winter, is most at risk.
If you see nesting material under the hood, a warning light after the car has been sitting, or droppings on top of the tires, mention it when you call. Your mechanic fixes the car; our job is to get the rodents out of the garage and stop new ones from coming in.
Stored items get hit too: patio cushions, holiday boxes, sleeping bags, the lawn mower bag and anything made of cardboard. Moving storage up off the floor and into sealed plastic bins makes a big difference.
Simple things Summit homeowners can do today
🥫
Close up the food
Put bird seed, grass seed, pet food and charcoal in metal or thick plastic bins with tight lids.
📦
Get boxes off the floor
Use shelves and sealed bins. Cardboard on a garage floor is a mouse's favorite place to nest.
🍂
Clear the edges
Pull leaves, ivy and firewood away from the foundation and the garage walls.
🚗
Keep the door down
Don't leave the garage door open for hours, especially at dusk in the fall.
These help, but they don't close the gaps rodents are already using. If you still see fresh droppings after a week or two, it's time for a professional look. Wondering about home remedies? Read does Irish Spring soap keep mice away.

Garage & Basement Rodent Questions from Summit
Why do I only see mice in the garage and not the house?
Usually because the garage is where they get in and find food. Garages have worn door seals, gaps at the slab and stored seed or pet food. Many homeowners find that the mice later move into the basement or walls once it gets colder, so it's best to deal with the garage before that happens.
How do mice get into a basement?
Most come in through gaps where the wood sill meets the foundation, around pipes and wires, through old basement windows and broken dryer vents. A mouse only needs a gap about the width of a pencil. That's why sealing those spots matters more than how many traps you set.
How long does garage and basement rodent control take?
Most homes see activity drop a lot within the first week or two once traps are set and gaps are sealed. Bigger problems, or rats, can take longer and need more follow-up visits. We check back and adjust, and mouse service includes 90 days of coverage with unlimited free service calls.
Is it safe to use poison in my garage?
We don't recommend loose poison in a garage. Pets, kids and other animals can get into it, and rodents that eat it can die inside walls and leave a smell. We use traps inside, out of reach, and locked tamper-resistant stations outside only where they make sense for the property.
Can mice damage my car if it's parked in the garage?
Yes. Mice and rats sometimes nest under the hood of a car that sits for days or weeks and can chew wiring and fill the air filter box with nesting material. Have your mechanic check the car, and get the rodents out of the garage so it doesn't keep happening.
Do you serve Summit, NJ?
Yes. We serve Summit and other Union County towns. We're based in Garfield, so Summit visits are usually scheduled ahead of time; same-day service is sometimes possible depending on the day. Call or text 973-510-2585 and we'll find the earliest time that works.
Will steel wool keep mice out of my basement?
Steel wool can help for a short time, but it rusts in damp basements and mice can pull it out. For lasting results, gaps should be closed with materials made for rodent exclusion and sealed in place. Our rodent proofing service does this as part of the job.
What should I do with droppings in the garage?
Don't sweep or vacuum them dry, because that can stir up dust. Wear gloves, spray the droppings with a disinfectant, wait a few minutes, then wipe them up and throw the towels away in a sealed bag. Wash your hands after, even with gloves on.
How much does rodent control for a garage and basement cost?
It depends on whether it's mice or rats, how long it's been going on, how many entry points there are and the size of the house. We give a free quote after we understand the property. Sending photos of the droppings and the garage door helps us give a better estimate.
