Treatment options and typical costs

Which rodents live around Centennial.
They can carry hantavirus, so clean up their droppings carefully. Deer mice live around Centennial too, mostly near open land and in sheds or cabins. 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 Centennial homes.
A good inspection starts outside at ground level: door thresholds, the joint between siding and foundation, and anywhere a pipe or cable enters.When they move in.
Check for gaps before then. Spring is breeding season. Small problems grow fast.
How they get into houses here.
Homes from Centennial out to Parker and Aurora share the same weak spots, so the checklist below works across the area. Window wells need covers or screens. Look at the dryer vent flap. Check where pipes and cables enter. Rodents use gaps around utility lines, dryer vents and window wells. Plenty of homes in Centennial have basements.
A year of rodents in Centennial.
- Fall: rodents look for shelter. Seal gaps before cold nights arrive. - Winter: with lows near 18°F in Centennial, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 88°F in Centennial, 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.
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. You should come away with a list of entry points. Photos help.
Rodents in the car.
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. Clear birdseed and pet food from the garage.
Bird feeders and rodents.
Spilled seed feeds mice and rats. 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.
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.)
Ways to keep the cost down.
- 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. - Compare what each quote seals, not just the price.
Rodents by the numbers.
Around Centennial, ask any provider to show you the entry points and the plan before you compare numbers. Around Centennial, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Around Centennial, 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
- Home size, stories, and roofline complexity.
- Sewer line inspection if rats are entering underground.
- Local labor rates and licensing costs.
- Whether sheds, garages or other outbuildings are included.
- Exterior bait stations and ongoing service frequency.
- Materials used for sealing: mesh, sheet metal, mortar.
- Follow-up visits included versus billed separately.
- Mice versus rats; rats take longer and cost more.

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