Treatment options and typical costs
Inspection and Entry-Point Mapping
$75–$250
Many credit the fee if you go ahead. Ask. Ask whether the report lists every entry point, because in Arvada that list is the real product.
- Time
- 60–90 minutes
- Best for
- Every job; nothing else works without it
Tamper-Resistant Exterior Bait Stations
$100–$300 setup, $40–$80 per service visit
Stations should be numbered and logged to show activity trends. A good pro shows you which stations get hit. Placement changes over time.
- Time
- 30–45 minutes per visit, ongoing
- Best for
- Outdoor rat pressure; ongoing perimeter protection
Attic and Crawlspace Cleanup and Sanitation
$500–$3,000, higher if insulation is replaced
Scent trails attract new rodents. Cleanup helps the sealing hold. Deodorizing and sealing an Arvada attic makes it less inviting to the mice outside looking for a way in.
- Time
- Half day to two days
- Best for
- Heavy contamination; odor, urine-soaked insulation, nesting
Sealing and Rodent-Proofing
$200–$1,500, more for large or complex homes
Price depends on how many openings the Arvada inspection found and how hard they are to reach. An Arvada ranch on a slab is cheaper to seal than a two-story home with a crawlspace and complex rooflines.
- Time
- 2–6 hours, sometimes a full day
- Best for
- Stopping re-entry for good; the lasting fix

Which rodents live around Arvada.
They're small, curious and breed quickly. Norway rats are the other usual suspect. They burrow along foundations and enter low. Deer mice live around Arvada too, mostly near open land and in sheds or cabins. They can carry hantavirus, so clean up their droppings carefully. House mice are the most common rodent in Arvada homes.
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.When they move in.
Spring is breeding season. Small problems grow fast. Check for gaps before then.
How they get into houses here.
Rodents use gaps around utility lines, dryer vents and window wells. Check where pipes and cables enter. Look at the dryer vent flap. Window wells need covers or screens. Homes from Arvada out to Westminster and Lakewood share the same weak spots, so the checklist below works across the area. Plenty of homes in Arvada have basements.
A year of rodents in Arvada.
- Summer: with highs around 89°F in Arvada, rodents look for water. Fix drips and leaks. - Fall: rodents look for shelter. Seal gaps before cold nights arrive. - Winter: with lows near 19°F in Arvada, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly.
Mice or rats?
- Rub marks: rats leave greasy smudges along walls and beams. - 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.
Sealing small gaps yourself.
- Check your work: daylight through a gap means it isn’t sealed. - 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.
Cleaning up droppings safely.
- Wash your gloved hands, then your hands. - 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.
What happens at an inspection.
The inspector walks the outside first. They check the foundation, vents, rooflines and utility gaps. Inside, they check the kitchen, garage and attic. You should come away with a list of entry points. Photos help. Most inspections take about an hour.
Rodents in the car.
Park in a closed garage when you can. 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.
Bird feeders and rodents.
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. Spilled seed feeds mice and rats.
Questions to ask before you sign.
- Will you use poison inside? (Ask them not to.) - 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?
Ways to keep the cost down.
- Compare what each quote seals, not just the price. - Clear clutter so gaps are easy to reach. - Store food and pet food in sealed bins. - Trim branches back from the roof. - Act early, before rodents spread to the attic.
Rodents by the numbers.
Across Arvada, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. Across Arvada, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Across Arvada, 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
- Whether sheds, garages or other outbuildings are included.
- Emergency or short-notice scheduling.
- Whether insulation must be removed and replaced.
- Sewer line inspection if rats are entering underground.
- Crawlspace or slab; crawlspaces add labor.
- Home size, stories, and roofline complexity.
- Local labor rates and licensing costs.
- Mice versus rats; rats take longer and cost more.

What's your biggest concern about rodent control costs?
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.

Across Arvada, rodents make up about 40 percent of all mammal species on Earth.
Questions people ask
Can I lower the cost by doing some work myself?
Yes. Clear garage clutter. Trim branches off the roof. That makes the sealing faster.
What do exterior bait stations cost?
Usually a setup fee plus a monthly or quarterly service charge. Ask how many stations they'll use and how often they're checked.
Does home size change the price?
Yes. Bigger houses have more walls and roofline to seal. Attics and crawl spaces add time too.
How much does attic cleanup cost?
It depends on the size and how much insulation is affected. Light cleanup can be a few hundred dollars. Full insulation replacement costs much more. Get it itemized.
Is it safe to clean up droppings myself?
For small amounts, yes, with care. Wear gloves and spray the droppings with a bleach solution. Wait five minutes, then wipe up with paper towels. Never sweep or vacuum them dry. Deer mice here can carry hantavirus. Take extra care in sheds.
How do I choose a rodent control company?
Make sure they're licensed in Colorado. 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.
How do I know if I have mice or rats?
Check the droppings. Mouse droppings are about the size of a rice grain. Rats also chew larger holes and sound heavier at night.
Are rodent problems in U.S. homes getting worse?
Not noticeably, on the national numbers. About 11.8% of occupied U.S. homes reported rodent signs in the preceding year, based on the U.S. Census Bureau's 2023 American Housing Survey (AHS) counts of 15.7 million out of 133.2 million. A good Arvada pro will walk you through how the plan matches what they found at your place.
Do wealthier homes get fewer mice and rats?
Not according to homeowner surveys. Across Arvada, in the National Pest Management Association's (NPMA) September 2022 Harris Poll of more than 1,300 U.S. homeowners, 52% of those earning $100,000 or more said they had ever had a rodent problem, slightly above the 49% for homeowners overall.
