Anyone in White Plains dealing with mice or rats, or hoping to keep them out.
What to look for
Rodents are mostly unseen. You hear them at night and find droppings by morning. A mouse fits through a gap the size of a dime. Seeing one in daylight usually means there are more.
- 1Burrow holes along the foundation, deck, or shed.
- 2Pipe gaps stuffed with debris or looking chewed wider.
- 3Scratching or scurrying sounds in walls or ceilings at night.
- 4A musky or ammonia-like smell in closed rooms.
- 5Shredded paper, fabric, or insulation gathered into a nest.
- 6Small dark droppings on top of the water heater.
Why it’s worth acting soon

House mice are the most common rodent in White Plains homes. They're small, curious and breed quickly. Norway rats are the other usual suspect. They burrow along foundations and enter low.
When they move in.
Small problems grow fast. Spring is breeding season. Check for gaps before then.
Fall is when rodents head indoors. Leaf piles against the foundation hide burrows and gaps, so clear them and walk the wall before the first cold snap.How they get into houses here.
Plenty of homes in White Plains have basements. Rodents use gaps around utility lines, dryer vents and window wells. Check where pipes and cables enter. Look at the dryer vent flap.

Mice or rats?
- Rub marks: rats leave greasy smudges along walls and beams. - Behavior: mice are curious about new traps. Rats avoid them for days. - Sounds: mice sound light and quick. Rats sound heavier. - Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized. - Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger.
Sealing small gaps yourself.
- Check your work: daylight through a gap means it isn’t sealed. - Expanding foam: fine on top of mesh, useless on its own. - Door sweeps: close the gap under garage and exterior doors. - Hardware cloth: use quarter-inch mesh over vents and larger holes. - Sealant or mortar: cover the mesh so it stays put. - Steel wool or copper mesh: pack it into small gaps first.
Cleaning up droppings safely.
- Wash your gloved hands, then your hands. - Don’t sweep or vacuum droppings dry. It stirs up dust. - Wipe up with paper towels and bag them. - Spray droppings with a bleach solution, then wait five minutes. - Wear rubber or plastic gloves. - Air the room out for 30 minutes first.
What happens at an inspection.
Photos help. You should come away with a list of entry points. Inside, they check the kitchen, garage and attic. They check the foundation, vents, rooflines and utility gaps. The inspector walks the outside first. Most inspections take about an hour.
Rodents in the car.
Clear birdseed and pet food from the garage. Check the air filter box for nesting. Park in a closed garage when you can. Mice and rats nest in engine bays and chew wiring.
Bird feeders and rodents.
Store seed in a metal can with a tight lid. If rodents show up, bring feeders in at night. Use a seed tray and sweep up spills. Spilled seed feeds mice and rats.
Questions to ask before you sign.
- Will you use poison inside? (Ask them not to.) - Is cleanup included, or extra? - What happens if they come back? - How many trap visits are included? - Which gaps will you seal, and with what? - Where are they getting in?
Rodents by the numbers.
National surveys set rough expectations but cannot diagnose one house. In White Plains, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. In White Plains, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. In White Plains, ask any provider to show you the entry points and the plan before you compare numbers.
What affects the price
- Number of entry points found during inspection.
- Sewer line inspection if rats are entering underground.
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Crawlspace or slab; crawlspaces add labor.
- Home size, stories, and roofline complexity.
- Attic access and how much insulation is contaminated.

What's your biggest concern about rodents?
When to call for help
Attic cleanup is hard to do safely without training. They take a longer, more careful approach. Call right away if you see rats. So is a dead-rodent smell. Droppings in several rooms are another sign. Call if you hear them in the attic or walls.
What you can do yourself
Start tonight with snap traps along the walls. Bait them with peanut butter. Store food in sealed bins. Seal small gaps with steel wool and sealant. Rooflines, vents and attics are harder. That's where a pro's sealing work pays off.
