Killeen, Texas, is a dynamic city in central Texas, best known as the home of Fort Cavazos (formerly Fort Hood), one of the largest military installations in the world. The city features a range of parks such as Lions Club Park, and its proximity to Stillhouse Hollow Lake offers residents and visitors access to boating and fishing. Killeen’s growth and diversity are closely tied to its military heritage and vibrant local economy.
Killeen lies within the Cross Timbers ecoregion, featuring gently rolling prairie with areas of Blackland Prairie soils. The city sits at an elevation of about 850 feet and is bordered to the south by Stillhouse Hollow Lake, a reservoir on the Lampasas River. These features provide varied habitats for both native and invasive pests, especially where water sources and open grasslands meet residential zones.

What our licensed technicians see on the ground in Bell County.
Termite pressure in Killeen reflects the region's humid subtropical climate and long warm season. Homes built on concrete slabs — particularly in neighborhoods like Harker Heights — provide subterranean colonies hidden access through plumbing penetrations and expansion joints. Mature tree canopies near Fort Cavazos (formerly Fort Hood) contribute to elevated soil moisture that accelerates colony growth. Romex certified applicators conduct annual monitoring with non-invasive bait stations and thermal imaging, catching active tubes before structural damage reaches the sills or sub-floor. Warranty-backed liquid treatments from Termidor or Taurus SC seal the perimeter for up to ten years.
Prevention tip: Keep mulch, firewood, and landscaping timbers at least 12 inches away from foundation walls and never stack firewood against the house.
Bell County ranks among the most mosquito-pressured areas in the region, thanks to the humid subtropical climate and dense tree canopy that blocks drying airflow after storms. Residents in Downtown Killeen frequently cite mosquito bites when they request service, especially during morning and evening hours. Vector-borne disease surveillance has confirmed West Nile and rarely EEE in Texas counties, making residual barrier treatments more than a comfort issue. Romex technicians map breeding sites with a property walk before any application.
Prevention tip: Walk your property weekly and dump any standing water — a discarded bottle cap can breed 300 mosquitoes in seven days.
Ant diversity is high in Killeen: we routinely identify fire ants, sugar ants (odorous house ants), rover ants, acrobat ants, and carpenter ants on a single property. Harker Heights is a textbook case — mosquitoes thrive near stillhouse hollow lake and wooded areas, while ants and termites are common in new construction. Near Fort Cavazos (formerly Fort Hood), 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: Never spray a visible ant trail indoors — it scatters the colony. Instead, call a professional to use targeted non-repellent products.
Killeen cockroach populations break into two groups: large outdoor-origin species (American, Smokybrown, Oriental) that wander in during temperature swings, and the German cockroach, an indoor-only pest spread by infested packaging and secondhand appliances. We see Smokybrown activity most often in wooded areas of Harker Heights, particularly in attics where they enter through roof vents and soffits. Commercial accounts near Fort Cavazos (formerly Fort Hood) occasionally deal with chronic German cockroach issues from high-volume food waste. Romex uses a two-phase protocol: Demand CS perimeter spray outdoors and Maxforce FC Magnum gel indoors.
Prevention tip: Inspect any secondhand appliance (especially microwaves, toaster ovens, mini fridges) before bringing it indoors — German cockroaches hitchhike inside.

Killeen experiences a humid subtropical climate, with average highs of 94°F in July and lows around 36°F in January. The city receives about 34 inches of rainfall annually, with spring and early summer being the wettest periods. The warm, humid environment accelerates the breeding cycles of mosquitoes, termites, and other pests.
Killeen’s proximity to Stillhouse Hollow Lake, open grasslands, and periodic flooding creates ideal conditions for mosquitoes and other water-loving pests. The mix of prairie and wooded areas supports a variety of rodents and wildlife that can encroach on homes, especially near the city’s edges. Sandy and clay soils are conducive to fire ant and termite activity.
Termite swarms are common after spring rains, especially in older neighborhoods. Mosquito populations rise near Stillhouse Hollow Lake and local creeks.
Warm, humid conditions drive up mosquito and fire ant activity. Scorpions and cockroaches are often found indoors as they seek cooler environments.
Rodents and spiders start moving indoors as temperatures cool. Fire ant activity persists, especially after rain.
Rodents seek shelter in homes and garages, while cockroaches remain active indoors. Pest pressure is lower but not absent in Killeen’s mild winters.
Pro Tip: Killeen homeowners save up to 40% with year-round protection plans that proactively treat for seasonal pests before they become infestations.
During World War II, pest management at Fort Hood (now Fort Cavazos) was a major logistical challenge, with military entomologists pioneering techniques to control mosquitoes and other vectors in Central Texas’ unique environment.
