Rats can travel plumbing, so a sink or floor drain with a missing strainer is worth fixing; a tight strainer or grate keeps them out.Which rodents live around Blacksburg.
They climb and come in high, through attics and rooflines. Roof rats turn up in parts of Virginia. 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 Blacksburg homes.
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.
Trim branches back from the roof. For roof rats, check soffit vents, gable vents and eaves. Homes from Blacksburg out to Roanoke share the same weak spots, so the checklist below works across the area. Look for gaps where pipes and wires pass through the floor. Make sure the crawl door closes tight. Check that vent screens are intact. A lot of houses around Blacksburg have crawl spaces, and crawl vents and access doors are the usual way in.
A year of rodents in Blacksburg.
- Summer: with highs around 83°F in Blacksburg, rodents look for water. Fix drips and leaks. - Spring: breeding season. Act on any sign quickly. - Winter: with lows near 24°F in Blacksburg, check the attic, garage and pantry for droppings. - Fall: rodents look for shelter. Seal gaps before cold nights arrive.
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. They'll also check the crawl space. 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.
Around Blacksburg, ask any provider to show you the entry points and the plan before you compare numbers. Around Blacksburg, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Around Blacksburg, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. National surveys set rough expectations but cannot diagnose one house.
What affects the price
- Materials used for sealing: mesh, sheet metal, mortar.
- Number of entry points found during inspection.
- Crawlspace or slab; crawlspaces add labor.
- Mice versus rats; rats take longer and cost more.
- Home size, stories, and roofline complexity.
- Emergency or short-notice scheduling.

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
That's where a pro's sealing work pays off. Rooflines, vents and attics are harder. Seal small gaps with steel wool and sealant. Store food in sealed bins. Bait them with peanut butter. Start tonight with snap traps along the walls.

Simple ways to keep rodents away
- Declutter garages and attics to remove nesting cover.
- Install brush or rubber door sweeps on exterior doors.
- Walk the exterior each season looking for fresh gnawing.
- Fill gaps around pipes, cables, and AC lines with copper mesh.
- Keep ivy, shrubs, and firewood away from the foundation.
- Trim tree branches at least six feet from the roof.

Questions people ask
Are snap traps better than poison?
Indoors, usually yes. Traps let you confirm the catch and remove it. Poisoned rodents can die inside walls and smell for weeks. Bait belongs in locked stations outside.
Do ultrasonic repellers work?
Not reliably. Rodents get used to the sound within days. It doesn't pass through walls either. Sealing and trapping work better.
Will rodent control harm my pets?
It shouldn't. Traps go where pets can't reach. Bait stations are locked. Tell the company about your pets before they start.
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.
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.
How many homes have a full rodent infestation?
Fourteen percent of U.S. homeowners told a September 2022 Harris Poll for the National Pest Management Association (NPMA) that they had dealt with an infestation of multiple rodents at some point. Before any work starts in Blacksburg, ask how many visits the price covers and what happens if rodents return.
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.
Are rodents a problem in Blacksburg?
