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.
- 1Small dark droppings on top of the water heater.
- 2Pipe gaps stuffed with debris or looking chewed wider.
- 3Rodent hair or droppings inside HVAC ducts.
- 4Tracks or tail drag marks in dust or flour.
- 5Bait or pet food vanishing from bowls overnight.

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.

They burrow along foundations and enter low. Roof rats turn up in parts of Virginia. They climb and come in high, through attics and rooflines. House mice are the most common rodent in Leesburg homes. They're small, curious and breed quickly. Norway rats are the other usual suspect.
When they move in.
Spring is breeding season. Small problems grow fast. 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.

Mice or rats?
- Holes: mice chew dime-sized holes. 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. - Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger.
Sealing small gaps yourself.
- 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. - Steel wool or copper mesh: pack it into small gaps first.
Cleaning up droppings safely.
- 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. - Air the room out for 30 minutes first.
What happens at an inspection.

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

What affects the price
- Follow-up visits included versus billed separately.
- Emergency or short-notice scheduling.
- Age of the home and condition of the foundation.
- Sewer line inspection if rats are entering underground.
- Whether insulation must be removed and replaced.

What's your biggest concern about rodents?
When to call for help
Call if you hear them in the attic or walls. Droppings in several rooms are another sign. So is a dead-rodent smell. Call right away if you see rats. They take a longer, more careful approach. Attic cleanup is hard to do safely without training.
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.

Questions people ask
Why do rodents keep coming back every year?
Usually because the entry points were never sealed. Traps remove the rodents inside. New ones follow the same path in.
Are rats a bigger problem than mice?
Usually. Rats are bigger, chew more, and avoid new traps for days. Around Leesburg, roof rats often nest in attics, so check the roofline too.
What is rodent-proofing and why does it cost so much?
It means sealing every gap with metal mesh and sealant. A mouse fits through a dime-sized gap, so it's slow work. It's also the part that keeps them out.
Will rodents leave on their own?
Rarely. Once they've found food, water and a warm nest, they stay.
How do I choose a rodent control company?
Make sure they're licensed in Virginia. Ask how they seal gaps and what materials they use. Ask what happens if rodents come back. A good company talks about sealing, not just traps.
Do wealthier homes get fewer mice and rats?
Not according to homeowner surveys. For Leesburg homes, rodents do not check tax returns: 52% of U.S. homeowners earning $100,000 or more reported a lifetime rodent encounter in the 2022 NPMA/Harris Poll, no lower than homeowners overall.
How common are rodent problems in U.S. homes?
Very common. In a Harris Poll conducted for the National Pest Management Association (NPMA) in September 2022, covering more than 1,300 U.S. homeowners, 49% said they had ever dealt with rodents.
