A Manchester winter is a rodent recruiter. When temperatures fall and snow covers the ground, mice and rats search for warmth, and the city's brick mills, old basements and tightly packed apartment blocks are full of openings. If you hear scratching or find droppings, call (844) 725-1661. We will connect you with an independent, licensed rodent control provider in Hillsborough County. PestMinistry is a referral service only; the provider handles trapping and exclusion.
The rodents of the Merrimack Valley
- House mice: the most frequent invaders, using small gaps to reach kitchens, pantries and wall voids.
- White-footed and deer mice: woodland species that move into garages, sheds and homes near woods in Bedford, Goffstown and the city's outer neighborhoods.
- Norway rats: burrowing rats in downtown alleys, along river banks, and near restaurants and dumpsters.
- Red squirrels and gray squirrels: not rats or mice, but frequent attic occupants that gnaw wiring.
Why the city's architecture helps rodents
The Amoskeag Millyard and nearby brick buildings contain miles of pipes, conduit and old floor penetrations. Loading docks, freight doors and basement tunnels are hard to seal completely. West Side and North End triple-deckers sit close together with shared walls and stairwells, so a rodent can move from house to house without leaving cover. Granite foundations and old mortar crumble, and snow banks pile against walls and hide gaps until spring. Restaurants on Elm Street and the downtown core generate waste that supports Norway rats, while the river corridors provide natural travel routes.
Spotting trouble
Droppings, gnawed boxes, shredded insulation and greasy marks along baseboards are the main clues. In snow, footprints and tunnels around the foundation can show where rodents travel. Scratching noises in the ceiling at night often indicate mice or squirrels. A musty odor in a closed pantry or closet suggests a nest. Outdoors, burrow holes next to the foundation or under steps indicate rats.
What the professional does
- Inspects exterior walls, basement, attic and shared areas, looking for gaps as small as a dime.
- Traps rodents with snap traps and secure bait stations placed along their routes.
- Seals gaps using steel mesh, concrete and metal flashing, and installs door sweeps and vent screens.
- Cleans droppings and nesting materials, sanitizing affected areas.
- Follows up to confirm there is no new activity.
In older buildings, exclusion can take several visits because gaps are numerous. Providers often prioritize the lowest levels and utility penetrations first.
Before the next freeze
- Clear snow away from vents, dryer exhausts and foundation edges.
- Store firewood on a rack at a distance from the house.
- Keep pet food and birdseed in metal bins.
- Seal around pipes, wires and cables in basements and utility rooms.
- Take trash out regularly and keep bins closed.
Timing in Manchester
Calls in Manchester climb sharply after the first hard frost, and again at the end of winter when stored food runs low outdoors. A pre-winter inspection is the cheapest moment to find gaps, and Manchester landlords with several buildings often schedule one every fall.
Health and safety
Rodent droppings and urine can spread illness and trigger allergies, and gnawed electrical wires are a fire hazard. If you find droppings, wet them with disinfectant and wipe up with gloves on. Larger infestations in a Manchester building should be handled by professionals.
Why do mice come into my house after the first snow?
Cold and snow cover reduce food and shelter outdoors, so they look for heated spaces.
How do I keep mice out of the garage?
Replace worn door seals, keep stored items off the floor, and remove food and bird seed.
Are glue traps recommended?
Many professionals avoid them due to animal welfare concerns and limited effectiveness. Snap traps are common.
Can mice chew through steel wool?
Not easily, especially when it is packed with sealant. Steel mesh and metal flashing are even better.
