HK Pest Control Services covers Lewisville from Edge Creek Path in north Carrollton, which sits right against the Castle Hills edge of the city — for a good part of Lewisville we are closer than most firms with a Lewisville address. Texas structural pest licence TPCL #13923, working here since 2004.

Lewisville is mostly water and floodplain, and it shows up in the call log

About 14% of the city is water. Lewisville Lake covers 29,592 acres along the north boundary, the Elm Fork of the Trinity River runs through the middle, and five named creeks — Timber, Prairie, Denton, Midway Branch and Indian — feed into it. The city’s own flood-protection material confirms central Lewisville is largely floodplain, and Central Park and Leonard L. Woods Park sit inside creek floodways by design.

Mosquitoes. The city runs nine core trap sites through the season, has used the same vector control contractor for eleven consecutive years, ground-sprays within a half-mile of any West Nile-positive trap, and hands out free mosquito dunks. In 2026 positives were reported near the 200 block of Highland Drive, the 900 block of Rachels Court and the 800 block of College Street. If you live inside one of those half-mile circles you get one municipal pass over the public right-of-way. Nothing in that programme touches the water holding in your own yard, which is where the mosquitoes biting you are actually being produced.

Wildlife in attics and soffits — the one we would lead with here. Lewisville Animal Services lists what residents genuinely run into: bats, armadillos, beavers, bobcats, coyotes, foxes, gophers, moles, opossums, rabbits, raccoons, skunks and squirrels. That is not padding. LLELA holds 2,600 acres of bottomland forest and tallgrass prairie with 360-plus vertebrate species at the north-east edge, and the Timber Creek, Prairie Creek and Indian Creek greenbelts are kept permanently undeveloped for flood control — wooded corridors running directly behind residential streets. Coyotes have been reported on Rockbrook Drive. Over 25 to 50-year-old rooflines with Eastern Cross Timbers oak canopy overhanging them, you get the standard entry set: lifted ridge vents, aging soffit returns, limbs touching the roof.

Two rodent environments. Homes backing the creek floodways have permanent cover and water at the property line — that will never be cleared, because the floodway is the flood plan. Old Town is the other one entirely: roughly fifteen dining and entertainment venues packed into two rows of century-old brick and timber on Main Street, including the Feed Mill from 1886 and Main Street Cafe and the Playhouse from 1885. Buildings that age have wall voids, unsealed penetrations and shared party walls, and the DCTA A-train and freight corridor runs through Old Town Station at 617 E. Main Street, which is a classic harborage line.

Termites, two ways. Median year built in Lewisville is 1997, so the biggest cohort — the 1970s to 1990s slab-on-grade wave — is now 30 to 50 years old. At that age the grade has settled below the slab edge, beds are built up against the foundation, and decades of irrigation have kept perimeter soil damp. Add the Elm Fork floodplain through the centre of town and slab-penetration and expansion-joint entry is the pattern. Old Town is the opposite exposure: 1880s to 1920s pier-and-beam and masonry with wood in ground contact. Same city, two genuinely different inspections.

Fire ants. Denton County sits inside the federal imported fire ant quarantine. What makes Lewisville worse than average is irrigated turf volume — Railroad Park alone has 16 sports fields and three irrigation lakes on one site, and the city holds over 3,000 acres of parks and open space. Mounds move from park turf into adjoining lawns after rain, and active construction at The Realm and Castle Hills Marketplace keeps turning fresh soil.

Castle Hills

Castle Hills was annexed into Lewisville on 15 November 2021 — about 2,568 acres and 18,000-plus residents. People still call it Castle Hills and so do we, but it is inside Lewisville city limits now, and it is the part of the city physically nearest our base. Worth knowing if you live there: the core sections date from 1998 through the 2000s, which puts a large share of those 4,300-plus homes at 20 to 28 years old — past the point where a builder’s original termite barrier can be assumed intact. Northpointe is still building 400-plus lots, and active construction pushes rodents and fire ants into finished streets nearby. The Lakes at Castle Hills golf course is built around lakes and water features, and The Realm and Crown Centre bring restaurant density that drives German cockroach pressure. Postal addresses out there split between 75056 and 75010, which confuses plenty of service companies but does not change who covers it.

How pests get into a slab house here

Most of Lewisville is slab-on-grade — no basement, no crawl space, so entry comes down to weep holes, slab expansion and control joints, garage-door corner seals, soffit and fascia gaps, the A/C line-set penetration and plumbing entries. Old Town is the exception and needs a different look entirely: pier-and-beam, ground contact, masonry voids.

Questions we get from Lewisville

The city sprayed my street for mosquitoes. Why am I still being bitten?

Municipal spraying is an adulticide pass over the public right-of-way after a trap tests positive. It kills flying adults in that window and does nothing to the breeding sites on your lot. If you are still being bitten a few days later, the source is almost certainly standing water in your own yard.

Something is in my attic and I back onto a creek greenbelt. What now?

Get it identified before anything else — bats are handled differently from squirrels and there are seasonal restrictions. Then trap and remove, then seal the entry. On a greenbelt-backing Lewisville home, skipping the exclusion step means the space is reoccupied fast.

Is Castle Hills in Lewisville or Carrollton?

Lewisville, since the November 2021 annexation, though many Castle Hills addresses still carry 75056 or 75010 mailing ZIPs. We cover all of it either way.

My Old Town building is over a hundred years old. Is that different?

Yes. Pier-and-beam construction with wood in ground contact, masonry wall voids and shared party walls is a different inspection and a different treatment plan from a 1990s slab in the suburbs.
