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

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 Salisbury.
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 Salisbury homes.
When they move in.
Small problems grow fast. Spring is breeding season. Check for gaps before then.
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.How they get into houses here.
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 Salisbury have basements.
A year of rodents in Salisbury.
- Summer: with highs around 87°F in Salisbury, rodents look for water. Fix drips and leaks. - Spring: breeding season. Act on any sign quickly. - Winter: with lows near 28°F in Salisbury, check the attic, garage and pantry for droppings. - Fall: rodents look for shelter. Seal gaps before cold nights arrive.
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. 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?
Rodents by the numbers.
Around Salisbury, ask any provider to show you the entry points and the plan before you compare numbers. Around Salisbury, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Around Salisbury, 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
- Emergency or short-notice scheduling.
- Number of entry points found during inspection.
- Attic access and how much insulation is contaminated.
- Materials used for sealing: mesh, sheet metal, mortar.
- Whether insulation must be removed and replaced.
- Local labor rates and licensing costs.

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
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.

Questions people ask
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 rats a bigger problem than mice?

What does a rodent inspection involve?
The inspector checks the outside walls, roofline, vents and utility gaps. Inside, they look at the kitchen, attic, garage and under sinks. You should get a list of entry points.
How long does rodent control take?
Most jobs take two to four weeks. That covers inspection, sealing and a few trap checks.
Why do rodents keep coming back every year?
