What to look for
Seeing one in daylight usually means there are more. A mouse fits through a gap the size of a dime. You hear them at night and find droppings by morning. Rodents are mostly unseen.
- 1Small dark droppings on top of the water heater.
- 2Chewed holes in the bottom of cabinets or drawers.
- 3Greasy rub marks along baseboards, beams, and pipe runs.
- 4Dead-animal odor that appears and slowly fades.
- 5Shredded paper, fabric, or insulation gathered into a nest.
- 6Burrow holes along the foundation, deck, or shed.
Why it’s worth acting soon
- Mice breed fast, every few weeks.
- Droppings and urine contaminate food and insulation.
- Gnawed wiring can be a fire risk.
- Nests and odor get harder to clean the longer they stay.

Cardboard boxes make easy nests and the gap under an overhead door makes an easy entrance. Plastic bins and a fresh door seal fix both.Which rodents live around Niagara Falls.
They burrow along foundations and enter low. Norway rats are the other usual suspect. They're small, curious and breed quickly. House mice are the most common rodent in Niagara Falls homes.
When they move in.
Check for gaps before then. Spring is breeding season. Small problems grow fast.
This is what a proper seal looks like: metal mesh fastened with screws and sealed at the edges. Foam or caulk on its own gets chewed through.How they get into houses here.

Act on any sign quickly. - Summer: with highs around 82°F in Niagara Falls, rodents look for water. Fix drips and leaks.
Mice or rats?

Rats chew holes closer to quarter-sized. - Sounds: mice sound light and quick. Rats sound heavier. - Behavior: mice are curious about new traps. Rats avoid them for days. - Rub marks: rats leave greasy smudges along walls and beams.
Sealing small gaps yourself.
- Steel wool or copper mesh: pack it into small gaps first. - Sealant or mortar: cover the mesh so it stays put. - Hardware cloth: use quarter-inch mesh over vents and larger holes. - Door sweeps: close the gap under garage and exterior doors. - Expanding foam: fine on top of mesh, useless on its own. - Check your work: daylight through a gap means it isn’t sealed.
Cleaning up droppings safely.
- Air the room out for 30 minutes first. - Wear rubber or plastic gloves. - Spray droppings with a bleach solution, then wait five minutes. - Wipe up with paper towels and bag them. - Don’t sweep or vacuum droppings dry. It stirs up dust. - Wash your gloved hands, then your hands.
What happens at an inspection.

Rodents in the car.
Mice and rats nest in engine bays and chew wiring. Park in a closed garage when you can. Check the air filter box for nesting. Clear birdseed and pet food from the garage.
Bird feeders and rodents.
Spilled seed feeds mice and rats. Use a seed tray and sweep up spills. If rodents show up, bring feeders in at night. Store seed in a metal can with a tight lid.

- Where are they getting in? - Which gaps will you seal, and with what? - How many trap visits are included? - What happens if they come back? - Is cleanup included, or extra? - Will you use poison inside? (Ask them not to.)

Questions people ask
How long does rodent control take?
Most jobs take two to four weeks. That covers inspection, sealing and a few trap checks.
Are snap traps better than poison?
Bait belongs in locked stations outside. Poisoned rodents can die inside walls and smell for weeks. Traps let you confirm the catch and remove it. Indoors, usually yes.
Do I need to replace attic insulation?
Ask the inspector to show you before you agree to replacement. Light activity can often be cleaned up. Only if it's heavily soiled or flattened by nesting.
Are rats a bigger problem than mice?
They also tend to need more sealing work outside. Rats are bigger, chew more, and avoid new traps for days. Usually.
Will rodents leave on their own?
Rarely. Once they've found food, water and a warm nest, they stay.
Does a house with structural problems attract more rodents?
Census Bureau's 2019 American Housing Survey (AHS) found that occupied homes with sloping, leaning or buckling exterior walls were 5.6 times as likely to report rodent sightings as other homes, an association among resident reports, not proof the walls caused the rodents. The U.S. The two go together, at least in the data.
Are rodent problems in U.S. homes getting worse?
