Pest Control in Scarborough, Maine

Scarborough looks different from Portland and South Portland in the Census numbers. It is mostly owner-occupied, mostly detached houses, and much of it is recent. We have not yet done a job in Scarborough that we can point to, so what follows is drawn from public data and from the kinds of work we already do elsewhere in Maine.

A newer, owner-occupied town

The U.S. Census Bureau’s American Community Survey for 2020–2024 counts 11,097 housing units in Scarborough. Its figures describe a town built largely in the last few decades:

• Owners, not renters. 77.4% of the 9,972 occupied homes are owner-occupied, so the person who finds the problem is usually the person who decides what to do about it.
• Young housing. 47.2% of units were built in 1990 or later, including 419 since 2020. Only 921 units, 8.3%, date from before 1940.
• Detached houses. 69.4% of units are single-family detached homes, and another 9.3% are attached single-family homes such as townhouses.
• Some seasonal stock. Of 1,125 vacant units, 853 are held for seasonal, recreational or occasional use.

That profile points to house-and-yard work rather than building-wide scheduling. The questions are where a single house lets pests in and what the lot around it is like.

Mice in newer houses

A house built in 2005 is tighter than one built in 1925, but it is not sealed. The gaps on newer houses tend to be in the same handful of places: the bottom and side seals on the garage door, the door from the garage into the living space, the line sets for heat pumps and air conditioning, dryer vents, and the joint where siding or trim stops above the foundation. In Auburn, a whole-home inspection we did turned up several entry points, and the one that mattered was the garage door seals where the garage meets the house. On a Scarborough house with an attached garage, that is where we would start.

The work we would quote is rodent exclusion: an itemized list of the openings, what each should be closed with, and trapping inside while that is done. If a gap needs a carpenter or a garage door company rather than us, the list says so.

Seasonal homes and closed-up buildings

The 853 seasonal units in the Census count are a reminder that some Scarborough buildings sit empty for part of the year. A house with nobody in it is quiet, warm enough in a crawlspace or wall, and unwatched, which suits mice. The visit that does the most good is before the building is closed: an inspection, sealing what can be sealed, and traps placed where they will catch rather than where they are convenient. The Maine pest calendar sets out why late summer is the time to do sealing work.

Ants at the foundation

Carpenter ants need damp wood, which a newer house has less of, but they find it where water collects: under a deck ledger, around a window that has been leaking into its frame, or where mulch and soil have built up against the siding. Pavement ants are more common at slab edges and walkways. For carpenter ants, the treatment is half the job and the moisture note in the report is the other half. Carpenter ant control explains what we look for.

Townhouses and shared walls

Not every Scarborough home stands alone. The Census Bureau’s 2020–2024 survey counts 1,028 attached single-family homes in the town, the townhouse and row-style units that share a side wall with a neighbor while each owner holds their own unit. Mice and insects treat that party wall as one structure. If the unit next door has an open gap at its sill or its garage, sealing only your side narrows the problem without ending it. On an attached unit we would note which openings belong to you, which sit in common areas, and which are on the neighbor’s side, so a condominium association or the adjoining owner can see the same list.

The marsh, the yard edge and ticks

Scarborough Marsh is, according to Maine Audubon, a 3,100-acre estuary and the largest salt marsh in the state, owned and managed by the Maine Department of Inland Fisheries and Wildlife. We mention it because it is part of what defines the town, not to claim anything about what it breeds.

Tick risk in the county is measured, and it is wider than Lyme. Maine CDC’s 2024 annual report, on preliminary data, records 147 anaplasmosis cases and 39 babesiosis cases among Cumberland County residents. UMaine Cooperative Extension’s Tick Lab tested 627 blacklegged ticks from the county in 2025 and found the Babesia parasite in 71 of them, 11.3%. The same 2025 report notes that Maine’s first Asian longhorned tick, a nymph, was acquired in Cumberland County. For a Scarborough yard, the useful work is at the edges, where mowed lawn meets brush, stone walls or woodland. Tick control covers what a yard treatment involves, and mosquito control covers the other summer complaint.
