They're small, curious and breed quickly. House mice are the most common rodent in Hillsboro 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.
Small problems grow fast. Spring is breeding season. Check for gaps before then.
How they get into houses here.
Trim branches back from the roof. For roof rats, check soffit vents, gable vents and eaves. Homes from Hillsboro out to Beaverton and Tigard share the same weak spots, so the checklist below works across the area. Look for gaps where pipes and wires pass through the floor. Make sure the crawl door closes tight. Check that vent screens are intact. A lot of houses around Hillsboro have crawl spaces, and crawl vents and access doors are the usual way in.
A year of rodents in Hillsboro.
- Summer: with highs around 81°F in Hillsboro, rodents look for water. Fix drips and leaks. - Spring: breeding season. Act on any sign quickly. - Winter: with lows near 36°F in Hillsboro, check the attic, garage and pantry for droppings. - Fall: mice move indoors as nights cool. Seal gaps in September.
Mice or rats?
- Rub marks: rats leave greasy smudges along walls and beams. - Behavior: mice are curious about new traps. Rats avoid them for days. - Sounds: mice sound light and quick. Rats sound heavier. - Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized. - Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger.
Sealing small gaps yourself.
- Check your work: daylight through a gap means it isn’t sealed. - Expanding foam: fine on top of mesh, useless on its own. - Door sweeps: close the gap under garage and exterior doors. - Hardware cloth: use quarter-inch mesh over vents and larger holes. - Sealant or mortar: cover the mesh so it stays put. - Steel wool or copper mesh: pack it into small gaps first.
Cleaning up droppings safely.
- Wash your gloved hands, then your hands. - Don’t sweep or vacuum droppings dry. It stirs up dust. - Wipe up with paper towels and bag them. - Spray droppings with a bleach solution, then wait five minutes. - Wear rubber or plastic gloves. - Air the room out for 30 minutes first.
What happens at an inspection.
Photos help. You should come away with a list of entry points. They'll also check the crawl space. Inside, they check the kitchen, garage and attic. They check the foundation, vents, rooflines and utility gaps. The inspector walks the outside first. Most inspections take about an hour.
Rodents in the car.
Clear birdseed and pet food from the garage. Check the air filter box for nesting. Park in a closed garage when you can. Mice and rats nest in engine bays and chew wiring.
Bird feeders and rodents.
Store seed in a metal can with a tight lid. If rodents show up, bring feeders in at night. Use a seed tray and sweep up spills. Spilled seed feeds mice and rats.
Questions to ask before you sign.
- Will you use poison inside? (Ask them not to.) - Is cleanup included, or extra? - What happens if they come back? - How many trap visits are included? - Which gaps will you seal, and with what? - Where are they getting in?
Ways to keep the cost down.
- Compare what each quote seals, not just the price. - Act early, before rodents spread to the attic. - Store food and pet food in sealed bins. - Clear clutter so gaps are easy to reach.
Rodents by the numbers.
Around Hillsboro, 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
- Materials used for sealing: mesh, sheet metal, mortar.
- Attic access and how much insulation is contaminated.
- Local labor rates and licensing costs.
- Crawlspace or slab; crawlspaces add labor.
- Whether sheds, garages or other outbuildings are included.
- Mice versus rats; rats take longer and cost more.
- Exterior bait stations and ongoing service frequency.
- Emergency or short-notice scheduling.

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
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.
