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.

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 Leawood.
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 Leawood 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 Leawood homes.
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.
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 Leawood out to Overland Park and Shawnee share the same weak spots, so the checklist below works across the area. Plenty of homes in Leawood have basements.
A year of rodents in Leawood.
- Summer: with highs around 89°F in Leawood, rodents look for water. Fix drips and leaks. - Fall: rodents look for shelter. Seal gaps before cold nights arrive. - Winter: with lows near 22°F in Leawood, 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?
Rodents by the numbers.
Across Leawood, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. Across Leawood, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Across Leawood, 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
- Crawlspace or slab; crawlspaces add labor.
- Emergency or short-notice scheduling.
- Number of trapping visits needed to reach zero.
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Age of the home and condition of the foundation.
- Exterior bait stations and ongoing service frequency.

What's your biggest concern about rodents?
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
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.

Hantavirus infections occur year-round but peak spring–summer with increased rodent exposure.
K-State's house mouse guide: one pair can produce more than 100,000 offspring in a year; control starts with sanitation and sealing openings larger than 1/4 inch.

Simple ways to keep rodents away
- Cap chimneys and repair damaged roof vents.
- Store pantry staples in glass or hard plastic.
- Keep grass short and remove tall weeds along fences.
- Trim tree branches at least six feet from the roof.
- Stack firewood off the ground and away from the house.
- Take bird feeders down or use catch trays for spilled seed.
In a multi-unit building, mice move between apartments through shared walls and pipe chases, so treating one unit rarely solves it. Ask for a building-wide plan.Did you know?
Across Leawood, a rodent's front teeth never stop growing, so it gnaws constantly to keep them worn down.
Across Leawood, rats are strong swimmers and can tread water for a long time, which is why they sometimes travel sewer lines.
Questions people ask
Can I just seal the holes myself?
Small gaps, yes. Use steel wool or copper mesh, then seal over it. Foam alone won't stop them. Rooflines and vents are harder, and that's where a pro helps.
Are rats a bigger problem than mice?
Usually. Rats are bigger, chew more, and avoid new traps for days. They also tend to need more sealing work outside.
How long does rodent control take?
Most jobs take two to four weeks. That covers inspection, sealing and a few trap checks.
How do I choose a rodent control company?
Make sure they're licensed in Kansas. 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.
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 common are rodent problems in U.S. homes?
Very common. If you have found a mouse in the house, you are in a large club: 49% of U.S. homeowners in a 2022 NPMA/Harris Poll reported a rodent encounter at some point in their lives.
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.
Are rodents a problem in Leawood?
They're common here, as almost everywhere. House mice cause most problems.
