Pest Control in Montgomery County, PA: 51 Towns From Pottstown to Narberth
Pest control in Montgomery County, PA covers Norristown rowhouses, Pottstown's old borough blocks, King of Prussia homes on the Valley Forge edge and new subdivisions in Upper Providence Township and Limerick Township. C.R. Davis III & Sons Pest Control, a family-owned company based just across the Schuylkill River in East Pikeland Township, serves 51 Montgomery County towns year-round.

Who serves your part of Montgomery County
Pest control in Montgomery County is split between our two service areas. Our Phoenixville base sits a short distance across the Schuylkill River and serves 49 Montgomery County towns: the US-422 corridor, the Perkiomen Valley, the North Penn area and east to Conshohocken, Whitemarsh and Ambler. Lower Merion Township and Narberth Borough belong to the West Chester service area, which is scheduled from Phoenixville until the West Chester location opens.
C.R. Davis III & Sons is family owned and operated, a Pennsylvania family corporation since 2003, licensed by the Pennsylvania Department of Agriculture in the Household and Health Related and Wood Destroying Pests categories, and insured. Every visit follows The Davis Inspection Standard: identify the species, name the conditions letting it in, treat where it lives per the label, and set a follow-up.
Montgomery County pest and vector facts
The PA Department of Environmental Protection recorded 133 West Nile virus positive mosquito samples and 4 human cases in Montgomery County during the 2025 season. CDC county counts show 714 Lyme disease cases in 2023, about 83.4 per 100,000 residents based on the 2020 Census, lower than the Chester County rate but still a reason to check for ticks after time along wooded trails.
All of Montgomery County has been inside the Pennsylvania spotted lanternfly quarantine since November 2017. Our spotted lanternfly guidance explains egg mass removal and the quarantine rules. Brown marmorated stink bugs move into homes in September and October, and Penn State Extension notes homes next to woods see more of them, which is the idea behind our stink bug and fall invader service.
Valley Forge, Evansburg and the Schuylkill: homes on wooded edges
Valley Forge National Historical Park reaches into Upper Merion, Lower Providence and West Norriton. The National Park Service reports that deer density there rose from 31 to 35 per square mile in 1983 to 241 by 2009, and management since then targets 20 to 25. Homes on the park edge in King of Prussia and Audubon back onto a lot of woodland.
Evansburg State Park covers 3,349 acres across Lower Providence, Skippack, Worcester, Lower Salford and Towamencin, and the Perkiomen Creek joins the Schuylkill River at Oaks. Wooded and creekside lots draw carpenter ants to damp framing and give stink bugs and cluster flies a short trip to the siding each fall. Our carpenter ant control starts with finding the wet wood.
Norristown rowhouses and Upper Providence Township subdivisions
Montgomery County has some of the oldest attached housing in our service area and some of the newest subdivisions. In Norristown, 55.4% of homes were built before 1960 and 47.1% are twins or rows; the West Norristown Historic District alone counts about 1,700 buildings, mostly rowhouses and semi-detached homes from 1885 to 1925. Old Pottstown's historic district has 956 contributing buildings. Shared walls and old foundations there call for mouse and rat control that seals entry points, and apartments call for cockroach control.
Upper Providence Township, Limerick Township, Skippack Township and New Hanover Township went the other way, with 37% to 47% of homes built since 2000. Penn State Extension notes termite damage typically shows 10 or more years after construction, so termite inspection and treatment matters there too.
| Municipality | Median year built | Built before 1940 | Single-family attached | Built 2000 or later |
|---|---|---|---|---|
| Narberth Borough | 1938 | 70.2% | 18.2% | 3.1% |
| Pottstown Borough | 1951 | 38.9% | 32.3% | 5.8% |

Services for Montgomery County homes and businesses
Buyers and sellers across the county use our real estate WDI inspections. Apartment owners and restaurants from Norristown to Lansdale can set up commercial pest control, and homeowners can put the house on a home pest control plan. Every service is listed on the services page. Call (610) 935-9130 to schedule.
Some services are best booked by season. Penn State Extension says termite swarmers usually emerge between February and June, paper wasp queens start nests in May, and yellow jackets get more defensive late in summer as food runs short. That makes spring the time to book termite work and early summer the time for wasp, hornet and yellow jacket nest removal, before a nest by a Lansdale or Blue Bell back door reaches full size. Bed bugs and German cockroaches ignore the calendar, and bed bug treatment runs year-round.

Pest control in Montgomery County: common questions
Do you provide pest control in Montgomery County, PA?
Yes. C.R. Davis III & Sons serves 51 Montgomery County municipalities. Forty-nine, including Norristown, King of Prussia, Pottstown, Collegeville, Lansdale and Ambler, are scheduled from our Phoenixville base. Lower Merion Township and Narberth are part of the West Chester service area. The phone number for every town is (610) 935-9130.
Which office serves Lower Merion and Narberth?
Lower Merion Township and Narberth Borough are part of the West Chester service area. The West Chester location is coming soon, so until it opens those appointments, including Ardmore, Bryn Mawr and Bala Cynwyd, are scheduled from our Phoenixville base at 153 Silver Springs Rd using (610) 935-9130.
How many West Nile virus cases did Montgomery County have in 2025?
Montgomery County had 4 human West Nile virus cases and 133 positive mosquito samples in the 2025 season, according to the PA Department of Environmental Protection. The department runs mosquito surveillance with the county each year and publishes the results in its seasonal summary for Pennsylvania.
Why do Norristown rowhouses have mouse problems?
Norristown rowhouses share walls, basements and roof lines, and mice travel through those connections. In Norristown Borough 47.1% of homes are twins or rows and 55.4% were built before 1960. We trap, find and seal entry points on your side, and tell you when the evidence suggests mice are coming from next door.
Are deer and ticks a concern near Valley Forge Park?
Valley Forge National Historical Park reached 241 deer per square mile in 2009 before the Park Service began reducing the herd toward 20 to 25. Homes along the park edge in King of Prussia, Audubon and West Norriton back onto large wooded areas, so tick checks after yard work and trail walks make sense.
Is Montgomery County in the spotted lanternfly quarantine?
Yes. All of Montgomery County has been inside the Pennsylvania spotted lanternfly quarantine since November 2017. Penn State Extension recommends scraping egg masses and checking vehicles and outdoor items before moving them out of the quarantine area. Lanternflies rarely become an indoor pest, but stink bugs and cluster flies do.
What will pest treatment not fix in a Montgomery County home?
Pest treatment does not fix moisture, wood-to-soil contact or open gaps in the building. A leaking gutter on a Pottstown twin or firewood against a Skippack deck keeps drawing carpenter ants and termites back. We write those conditions down so the homeowner or a contractor can repair them alongside treatment.
