Treatment options and typical costs
Inspection and Entry-Point Mapping
$75–$250
The inspection identifies the species and how bad it is. Droppings, grease trails, and nest material in Modesto attics and crawlspaces show how long they have been there.
- Time
- 60–90 minutes
- Best for
- Every job; nothing else works without it
Sealing and Rodent-Proofing
$200–$1,500, more for large or complex homes
Sealing the gaps is what separates a fix from a subscription. Once Modesto homes are properly sealed, trapping wraps up quickly and bait stations become optional rather than essential.
- Time
- 2–6 hours, sometimes a full day
- Best for
- Stopping re-entry for good; the lasting fix
Follow-Up Monitoring
$50–$150 per visit, or included in a plan
Fresh droppings look dark and soft; old ones look gray. That tells a pro whether activity is current.
- Time
- 20–40 minutes per visit
- Best for
- Confirming the house stays clear after treatment
Tamper-Resistant Exterior Bait Stations
$100–$300 setup, $40–$80 per service visit
This is a maintenance tool, not a one-time fix. In Modesto neighborhoods with steady rat pressure from alleys, creeks, or restaurants, stations are checked and refilled on a schedule.

Which rodents live around Modesto.
They can carry hantavirus, so clean up their droppings carefully. Deer mice live around Modesto too, mostly near open land and in sheds or cabins. They climb, and come in high through attic vents and branches. Roof rats are common around Modesto too. 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 Modesto homes.
A metal vent cover with a working flap keeps mice out all winter. Plastic flaps crack in the cold and get chewed open.When they move in.
Check for gaps before then. Roof rats are active all year. Listen for them in the attic after dark. Spring is breeding season. Small problems grow fast.
How they get into houses here.
Trim branches back from the roof. For roof rats, check soffit vents, gable vents and eaves. Homes from Modesto out to Stockton 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 Modesto have basements.
A year of rodents in Modesto.
- Fall: rodents look for shelter. Seal gaps before cold nights arrive. - Winter: with lows near 38°F in Modesto, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 94°F in Modesto, 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. - Act early, before rodents spread to the attic. - Compare what each quote seals, not just the price.
Rodents by the numbers.
Around Modesto, ask any provider to show you the entry points and the plan before you compare numbers. Around Modesto, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Around Modesto, 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
- Mice versus rats; rats take longer and cost more.
- Whether insulation must be removed and replaced.
- Number of entry points found during inspection.
- Emergency or short-notice scheduling.
- Exterior bait stations and ongoing service frequency.
- Whether sheds, garages or other outbuildings are included.
- Follow-up visits included versus billed separately.
- Outdoor pressure from creeks, alleys, or restaurants nearby.

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