Union Park is a master-planned community located in Little Elm, within Denton County, Texas. The city is known for its 30-acre central park, extensive walking trails, and proximity to Lewisville Lake. Union Park is part of the Denton Independent School District and features modern amenities alongside preserved green spaces.
Union Park sits on the gently rolling terrain of the North Texas Blackland Prairie, with clay-rich soils that retain moisture and promote robust vegetation. The elevation is around 600 feet, and the community is situated just east of Lewisville Lake, influencing local humidity and pest habitats. Nearby wooded areas and open grasslands provide ideal environments for a range of insect and rodent species.
An active adult neighborhood within Union Park offering age-restricted homes and resort-style amenities.
Common issues include mosquitoes from nearby water features and occasional ant infestations due to lush landscaping.
Residential area bordering open fields and walking trails.
Increased sightings of rodents and snakes, especially near undeveloped lots and tall grasses.
The heart of the community, featuring the main park and playgrounds.
Frequent problems with stinging insects like wasps and bees near picnic areas and playgrounds.
Homes closest to the community's entry and bordering greenbelt areas.
Higher prevalence of termites and carpenter ants due to mature trees and mulch beds.
What our licensed technicians see on the ground in Denton.
Subterranean termites are the dominant species targeting homes throughout Union Park and Denton County. Older properties in Del Webb at Union Park are especially vulnerable, where soil moisture and wood-to-ground contact create ideal conditions for Eastern subterranean colonies. Romex inspectors have identified active infestations within a few miles of Union Park Central Park, typically in homes built before 2000 with untreated crawl spaces or slab cracks. Swarmer flights in March through May provide the clearest early warning. We use Termidor HE liquid treatments and Sentricon bait stations to protect the entire structure rather than spot-treating visible damage.
Prevention tip: Keep mulch, firewood, and landscaping timbers at least 12 inches away from foundation walls and never stack firewood against the house.
Mosquito populations in Union Park surge from April through October, driven by standing water that collects in gutters, bird baths, bromeliad pockets, and drainage ditches. North Union Park sees particularly high pressure because increased sightings of rodents and snakes, especially near undeveloped lots and tall grasses.. Our service crews have documented heavy activity within 500 feet of Lewisville Lake, where untreated vegetation provides daytime harborage for Aedes albopictus and Culex quinquefasciatus. We apply In2Care stations and barrier treatments with Talstar P that last up to 30 days per application.
Prevention tip: Clean gutters at least twice per year; clogged gutters are the #1 overlooked breeding site we find in Union Park yards.
Ant diversity is high in Union Park: we routinely identify fire ants, sugar ants (odorous house ants), rover ants, acrobat ants, and carpenter ants on a single property. Del Webb at Union Park is a textbook case — common issues include mosquitoes from nearby water features and occasional ant infestations due to lush landscaping. Near Union Park Central Park, crazy ants have been documented on a few properties, requiring specialized bait protocols. Romex applicators never recommend over-the-counter aerosols for trails because they scatter satellite colonies and make the problem worse.
Prevention tip: Seal gaps around exterior pipe penetrations and weather-stripping; most indoor ant trails originate at these entry points.
Oriental cockroaches ("black beetles") thrive in the cool, damp spaces under Denton County homes — crawl spaces, storm drains, and garage corners. Del Webb at Union Park homeowners call about them most often in early fall, when roaches seek warmer harborage. Our inspection covers the foundation perimeter for harborage (leaf litter, mulch depth, downspout splash zones) before any product goes down. We follow up with crack-and-crevice Premise 0.05 applications in areas of high moisture.
Prevention tip: Keep a screen or mesh cover on floor drains in garages and utility rooms; American roaches routinely enter through these.

Union Park experiences a humid subtropical climate, with average summer highs in the mid-90s°F and winter lows in the 30s°F. Annual rainfall averages 38 inches, and high humidity supports mosquito and termite activity. Warm, wet springs and summers accelerate pest breeding cycles.
Union Park's proximity to Lewisville Lake and several greenbelt areas creates abundant habitats for mosquitoes, ants, and rodents. The clay-based soils allow for moisture retention, supporting termite populations and lush vegetation that attracts additional pests. Dense housing and shared amenities can also contribute to rapid pest spread.
Warming temperatures and increased rainfall near Union Park's parks and lakes trigger mosquito and termite swarms. Ants and wasps become more active in yards and community spaces.
Hot, humid weather supports high mosquito and fly populations, especially near Lewisville Lake and shaded trails. Fire ant mounds are common in lawns and parks.
Rodents seek shelter indoors as nighttime temperatures drop. Spider and cockroach sightings increase in homes and community buildings.
