Anyone in Boulder City dealing with mice or rats, or hoping to keep them out.
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.

Roof rats and mice love attic insulation. Tunnels through the fluff, flattened runways and droppings along the eaves are the signs to look for.Which rodents live around Boulder City.
They're small, curious and breed quickly. Norway rats are the other usual suspect. They burrow along foundations and enter low. Roof rats turn up in parts of Nevada. They climb and come in high, through attics and rooflines. Deer mice live around Boulder City too, mostly near open land and in sheds or cabins. They can carry hantavirus, so clean up their droppings carefully. Pack rats, also called woodrats, are common around Boulder City. They nest under decks and in vehicles, and chew engine wiring. House mice are the most common rodent in Boulder City homes.
When they move in.
Check for gaps before then. Spring is breeding season. Small problems grow fast.
Dense shrubs against the house and a dripping hose bib give rodents cover and water. Trimming back and fixing drips makes the yard less inviting.How they get into houses here.
Garage seals, brick weep holes and pipe gaps are typical entries. Check the bottom corners of the garage door. Look behind the washer and under sinks. Daylight under a door means a gap. Homes from Boulder City out to Henderson and North Las Vegas share the same weak spots, so the checklist below works across the area. For roof rats, check soffit vents, gable vents and eaves. Trim branches back from the roof. Many homes in Boulder City sit on slabs.
A year of rodents in Boulder City.
- Fall: rodents look for shelter. Seal gaps before cold nights arrive. - Winter: with lows near 38°F in Boulder City, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 104°F in Boulder City, rodents look for water. Fix drips and leaks.
Mice or rats?
- Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger. - 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.
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.
You should come away with a list of entry points. Photos help. Most inspections take about an hour. The inspector walks the outside first. They check the foundation, vents, rooflines and utility gaps. Inside, they check the kitchen, garage and attic.
Rodents in the car.
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. Check the air filter box for nesting.
Bird feeders and rodents.
Store seed in a metal can with a tight lid. Spilled seed feeds mice and rats. Use a seed tray and sweep up spills. If rodents show up, bring feeders in at night.
Questions to ask before you sign.
- 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.)
Rodents by the numbers.
Across Boulder City, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. Across Boulder City, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Across Boulder City, ask any provider to show you the entry points and the plan before you compare numbers. National surveys set rough expectations but cannot diagnose one house.
What affects the price
- Emergency or short-notice scheduling.
- Whether insulation must be removed and replaced.
- Number of trapping visits needed to reach zero.
- Exterior bait stations and ongoing service frequency.
- Local labor rates and licensing costs.
- Crawlspace or slab; crawlspaces add labor.

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
- Move compost bins away from the house and use closed models.
- Trim tree branches at least six feet from the roof.
- Seal the gap where the garage slab meets the wall.
- Inspect vehicle engine bays if parked near fields or woods.
- Seal every gap larger than a quarter inch with metal mesh.
- Install brush or rubber door sweeps on exterior doors.

A house mouse can jump about a foot straight up.

Questions people ask
Do ultrasonic repellers work?
It doesn't pass through walls either. Sealing and trapping work better. Not reliably. Rodents get used to the sound within days.
What is rodent-proofing and why does it cost so much?
A mouse fits through a dime-sized gap, so it's slow work. It's also the part that keeps them out. It means sealing every gap with metal mesh and sealant.
Do I need to replace attic insulation?
Light activity can often be cleaned up. Ask the inspector to show you before you agree to replacement. Only if it's heavily soiled or flattened by nesting.
Are snap traps better than poison?
Poisoned rodents can die inside walls and smell for weeks. Bait belongs in locked stations outside. Indoors, usually yes. Traps let you confirm the catch and remove it.
How long does rodent control take?
Most jobs take two to four weeks. That covers inspection, sealing and a few trap checks.
How many homes in the U.S. have mice or rats?
The U.S. Census Bureau's 2019 American Housing Survey (AHS) found that 11.9% of occupied homes had seen rodents or evidence of them in the preceding year. About one in eight report them.
Are rodent problems in U.S. homes getting worse?
homes reported signs in the previous year, calculated from the U.S. Census Bureau's 2023 American Housing Survey (AHS) rounded counts, almost identical to 2019. Not noticeably, on the national numbers. Rodent contact has stayed steady: roughly 11.8% of occupied U.S.
