Anyone in Henderson dealing with mice or rats, or hoping to keep them out.
What to look for
A mouse fits through a gap the size of a dime. Seeing one in daylight usually means there are more. Rodents are mostly unseen. You hear them at night and find droppings by morning.

- 2Shredded paper, fabric, or insulation gathered into a nest.

- 4Scratching or scurrying sounds in walls or ceilings at night.
- 5Bait or pet food vanishing from bowls overnight.
- 6Food scattered or hollowed-out fruit and nuts.
Why it’s worth acting soon
- Mice breed fast, every few weeks.
- Droppings and urine contaminate food and insulation.
- Gnawed wiring can be a fire risk.

Treatment options and typical costs
Inspection and Entry-Point Mapping
$75–$250
An inspection starts outside. The pro checks the foundation, roofline and utility gaps. Inside, they check attics, crawlspaces, and appliances for droppings and gnawing.

- Every job; nothing else works without it
Tamper-Resistant Exterior Bait Stations
$100–$300 setup, $40–$80 per service visit

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 Henderson.
House mice are the most common rodent in Henderson homes. They're small, curious and breed quickly. Norway rats are the other usual suspect. They burrow along foundations and enter low.
When they move in.
Check for gaps before then. Spring is breeding season. Small problems grow fast.
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.
A lot of houses around Henderson have crawl spaces, and crawl vents and access doors are the usual way in. Check that vent screens are intact. Make sure the crawl door closes tight. Look for gaps where pipes and wires pass through the floor. Homes from Henderson out to Owensboro share the same weak spots, so the checklist below works across the area.
A year of rodents in Henderson.
- Fall: rodents look for shelter. Seal gaps before cold nights arrive. - Winter: with lows near 26°F in Henderson, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 89°F in Henderson, 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. They'll also check the crawl space. 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.)
Rodents by the numbers.
National surveys set rough expectations but cannot diagnose one house. In Henderson, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. In Henderson, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. In Henderson, ask any provider to show you the entry points and the plan before you compare numbers.
What affects the price
- Follow-up visits included versus billed separately.
- Local labor rates and licensing costs.
- Whether sheds, garages or other outbuildings are included.
- Age of the home and condition of the foundation.
- Number of entry points found during inspection.
- Attic access and how much insulation is contaminated.

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.

Questions people ask
What should be in a rodent control quote?
Entry points, sealing materials and the number of trap visits. It should say what happens if they return. Cleanup should be listed separately.
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.
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 rodents leave on their own?
Rarely. Once they've found food, water and a warm nest, they stay.
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.
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. In Henderson, the next step is usually an inspection that finds where the rodents are getting in.
How many homes have a full rodent infestation?
