Keene, Texas is a small city in Johnson County, known for being home to Southwestern Adventist University, which gives the city a vibrant academic atmosphere. The city features the Keene City Park and is surrounded by gently rolling prairie, with the Nolan River flowing nearby. Keene’s history is closely tied to the development of the Seventh-day Adventist community in Texas, dating back to its founding in the late 19th century.
Keene sits on the Cross Timbers ecological region, characterized by sandy loam soils and gently undulating terrain at an elevation of about 860 feet. The area is interspersed with patches of post oak woodland and native prairie, providing habitat for both native and invasive pests. The proximity to the Nolan River, as well as seasonal creeks, creates moist microclimates that can increase mosquito and termite populations.

What our licensed technicians see on the ground in Johnson County.
Subterranean termites are the dominant species targeting homes throughout Keene and Johnson County. Older properties in Old Town Keene 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 Southwestern Adventist University, 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: Schedule an annual professional termite inspection; WDO damage in Keene typically goes undetected for 3–5 years before visible signs appear.
Asian tiger mosquitoes (Aedes albopictus) are the most aggressive biters in Keene, and unlike native species they are day-active. Properties within a mile of Keene City Park see elevated pressure due to tree cover and nearby drainage. In neighborhoods like North Keene, the yard-to-yard flight range means a single neglected container can re-infest the whole block within a week. Our integrated mosquito program combines source reduction (we identify and eliminate breeding sites during the initial inspection) with a 30-day residual spray on foliage below eight feet, the resting zone for adult females.
Prevention tip: Use a dunk-style larvicide (Bti) in any decorative pond, rain barrel, or low spot that can't be drained within a week.
Ant diversity is high in Keene: we routinely identify fire ants, sugar ants (odorous house ants), rover ants, acrobat ants, and carpenter ants on a single property. Old Town Keene is a textbook case — mature trees and aging structures attract carpenter ants, termites, and rodents. Near Southwestern Adventist University, 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.
Oriental cockroaches ("black beetles") thrive in the cool, damp spaces under Johnson County homes — crawl spaces, storm drains, and garage corners. Old Town Keene 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: Eliminate moisture around the foundation: fix splash blocks, grade soil away from the house, and repair any dripping outdoor faucets.

Keene experiences a humid subtropical climate with hot summers (average highs in the low to mid-90s °F) and mild winters (average lows in the 30s-40s °F). Annual rainfall averages around 36 inches, with higher humidity in spring and early summer. This climate supports high insect activity, especially mosquitoes, ants, and cockroaches, which thrive in the warmth and moisture.
Keene’s blend of prairie, woodland, and nearby water bodies creates habitats for a wide variety of pests. Sandy soils and mature trees support termites and carpenter ants, while the proximity to agricultural land increases the risk of grasshoppers and field mice. The seasonal presence of the Nolan River and local creeks also encourages mosquito breeding, especially following spring rains.
With rising temperatures and increased rainfall, termites begin to swarm and mosquitoes emerge near the Nolan River and city parks. Ants and crickets invade homes as outdoor activity increases.
Warm, humid conditions drive up mosquito and wasp populations, especially in irrigated areas like the university and parks. Field mice can be seen in neighborhoods bordering open fields.
Cooler weather pushes rodents and spiders indoors, particularly in older parts of Keene. Ants may also seek food and shelter inside as outdoor resources dwindle.
Rodents remain active indoors, especially in neighborhoods near fields and wooded areas. Cockroaches seek warmth in homes and businesses throughout Keene.
Pro Tip: Keene homeowners save up to 40% with year-round protection plans that proactively treat for seasonal pests before they become infestations.
In 2018, Keene’s city parks introduced native wildflower plantings to attract pollinators, but these efforts also led to a noted uptick in local bee and wasp activity, prompting new pest management strategies around playgrounds and picnic areas.
