Homeowners, renters and landlords in Dickinson who are hearing, seeing or smelling signs of rodents.
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.
- 1Scratching or scurrying sounds in walls or ceilings at night.
- 2Live sighting, especially during the day.
- 3Food scattered or hollowed-out fruit and nuts.
- 4Pipe gaps stuffed with debris or looking chewed wider.
- 5Rodent hair or droppings inside HVAC ducts.
- 6Tracks or tail drag marks in dust or flour.
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.
- Nests and odor get harder to clean the longer they stay.
- Deer mice can carry hantavirus.
Treatment options and typical costs
Inspection and Entry-Point Mapping

Snap-Trap Program
$150–$400 per visit

Attic and Crawlspace Cleanup and Sanitation
$500–$3,000, higher if insulation is replaced

- Half day to two days
- Best for
- Heavy contamination; odor, urine-soaked insulation, nesting
Follow-Up Monitoring
$50–$150 per visit, or included in a plan

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 Dickinson.
They burrow along foundations and enter low. Deer mice live around Dickinson 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 Dickinson homes. They're small, curious and breed quickly. Norway rats are the other usual suspect.
When they move in.
Spring is breeding season. Small problems grow fast. Check for gaps before then.
A good inspection starts outside at ground level: door thresholds, the joint between siding and foundation, and anywhere a pipe or cable enters.How they get into houses here.
Check where pipes and cables enter. Look at the dryer vent flap. Window wells need covers or screens. Plenty of homes in Dickinson have basements. Rodents use gaps around utility lines, dryer vents and window wells.
A year of rodents in Dickinson.
- Winter: with lows near 4°F in Dickinson, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 84°F in Dickinson, rodents look for water. Fix drips and leaks. - Fall: mice move indoors as nights cool. Seal gaps in September.
Mice or rats?
- 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. - Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger.
Sealing small gaps yourself.
- 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. - Steel wool or copper mesh: pack it into small gaps first.
Cleaning up droppings safely.
- 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. - Air the room out for 30 minutes first.
What happens at an inspection.
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. The inspector walks the outside first. They check the foundation, vents, rooflines and utility gaps.
Rodents in the car.
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. Park in a closed garage when you can.
Bird feeders and rodents.
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. Use a seed tray and sweep up spills.
Questions to ask before you sign.
- 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.) - Where are they getting in?
Rodents by the numbers.
For Dickinson homes, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. For Dickinson homes, 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. For Dickinson homes, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is.
What affects the price
- Whether sheds, garages or other outbuildings are included.
- Materials used for sealing: mesh, sheet metal, mortar.
- Exterior bait stations and ongoing service frequency.
- Crawlspace or slab; crawlspaces add labor.
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Follow-up visits included versus billed separately.

What's your biggest concern about rodents?
When to call for help
Call right away if you see rats. They take a longer, more careful approach. Attic cleanup is hard to do safely without training. Call if you hear them in the attic or walls. Droppings in several rooms are another sign. So is a dead-rodent smell.
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.
Rodents in Dickinson

Questions people ask
How do I choose a rodent control company?
Make sure they're licensed in North Dakota. 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.
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.
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.
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.
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. Expect a good pro in Dickinson to connect their plan to what they actually found at your home.
How many homes in the U.S. have mice or rats?
About one in eight report them. Eleven point nine percent of occupied U.S. homes reported seeing rodents or signs of them in the previous 12 months, according to the U.S. Census Bureau's 2019 American Housing Survey (AHS). As you collect quotes in Dickinson, ask each company what they usually run into in your neighborhood.
