Local Service Coverage In Bexar County

Roger and Keri Vasquez serve homeowners across Bexar County with 8+ years of hands-on experience treating rodents, cockroaches, ants, scorpions, and other pests common to our region. San Antonio’s warm, humid climate means pests stay active year-round, making local pest control expertise and fast response times important for protecting your home.
We’re born and raised in San Antonio, so we understand how clay soil foundation settling creates pest entry points, why fire ants thrive after summer rains, and which neighborhoods face unique pest pressure from nearby greenbelts or older construction. Over 70 five-star Google reviews from your neighbors across these communities.
San Antonio
Our primary service area covers all of San Antonio and Bexar County. The cities served by Rat King Pest Control range from historic neighborhoods with 1920s construction to brand-new master-planned communities. We’ve treated pest issues in every type of housing stock across the city. San Antonio’s subtropical climate supports year-round pest activity, unlike northern states where insects go dormant in winter.
Clay soil common throughout Bexar County causes foundation settling that creates new cracks and gaps where pests enter. We seal these entry points as part of rodent control and quarterly pest prevention service. Same-day appointments available for urgent situations.
Leon Valley
Leon Valley properties often experience moisture-related pest issues due to the area’s terrain and older housing stock. Silverfish, centipedes, and American cockroaches thrive in humid environments like bathrooms and crawl spaces. We treat moisture pests at the source while recommending humidity control solutions.
Rodent activity increases in Leon Valley during fall and winter as rats and mice seek indoor shelter. Foundation gaps and utility line openings provide easy access. Our rodent exclusion service seals these entry points using materials rodents can’t chew through.
Converse
Converse homes near Randolph Air Force Base and surrounding areas face consistent pest pressure from nearby undeveloped land. Fire ants establish mounds quickly in yards and landscaping. Broadcast treatment prevents new colonies while individual mound injections eliminate existing nests.
German cockroach infestations spread rapidly in Converse apartments and multi-family housing. These fast-breeding roaches hide in kitchen and bathroom cracks, requiring targeted baiting instead of surface spraying. We eliminate entire colonies including eggs with growth regulators and follow-up treatments.
Live Oak
Live Oak properties backing to greenbelts and natural areas experience higher rodent and wildlife pressure. Roof rats access attics through tree branches and power lines. We inspect roof vents, eaves, and soffit areas for entry points, then trap active rats and seal access routes..
Scorpions are common in Live Oak, especially near rocky or brushy areas. Striped bark scorpions hide in shoes, storage boxes, and behind furniture. Our scorpion prevention includes exterior barrier treatment, dust application in wall voids, and sealing gaps around doors and windows.
Universal City
Universal City homeowners near Randolph Air Force Base deal with ants, roaches, and seasonal cricket invasions. Fire ant mounds rebuild quickly in San Antonio’s warm soil, requiring consistent quarterly treatment to prevent new colonies from establishing in yards and play areas.
Cricket activity peaks in fall as field crickets migrate indoors seeking moisture. Perimeter treatment stops them before entry, reducing the constant chirping noise in garages and utility rooms. Treatment lasts approximately 90 days between quarterly service visits.
Alamo Heights
Alamo Heights historic homes date back to the 1920s and 1930s, creating more pest entry points through foundation cracks, old plumbing penetrations, and settling gaps. We specialize in treating older construction where mice can squeeze through dime-sized openings and rats exploit quarter-inch gaps around utilities.
German cockroaches thrive in Alamo Heights multi-family properties and older apartment buildings. These roaches survive on minimal food sources like cardboard glue and grease residue. Baiting reaches hidden harbors in wall voids and cabinet cracks where spraying can’t access.
Terrell Hills
Terrell Hills properties face similar pest challenges as Alamo Heights due to older housing stock and mature tree canopy. Roof rats climb oak and pecan trees to access attic spaces. We trim tree branches away from rooflines and seal roof vents, soffit gaps, and eave openings used for entry.
Spider populations increase in Terrell Hills garages and storage areas, including brown recluse and black widow species. Exterior perimeter treatment eliminates webs and egg sacs before spiders move indoors. We target harbors in rarely disturbed areas like crawl spaces and attic corners.
Olmos Park
Olmos Park homes near Olmos Basin and the creek area experience higher moisture levels that attract silverfish, centipedes, and American cockroaches. These moisture pests damage books, wallpaper, and stored fabrics. We treat bathrooms, closets, and basements while identifying humidity sources feeding the problem.
Mosquito activity peaks during summer months near water features and shaded yard areas. Yard treatment targets breeding sites in standing water. We also treat entry points around doors and windows to stop mosquitoes from accessing interior spaces.
Monte Vista
Monte Vista historic district homes feature beautiful 1920s architecture with equally old foundations, plumbing, and utility penetrations. Foundation settling from Bexar County’s clay soil creates new pest entry points yearly. Our rodent exclusion service uses steel wool, caulk, and metal screening to seal gaps around pipes, vents, and foundation cracks.
Termite pressure is higher in Monte Vista due to older wood framing and foundation structures. While we don’t treat termites, we can identify signs of activity during pest inspections and recommend specialized termite services if needed.
Stone Oak
Stone Oak properties include newer master-planned communities with homes backing to greenbelts and natural preserves. This proximity to undeveloped land increases rodent and wildlife encounters. Roof rats nest in attics, while raccoons and squirrels seek shelter in attic spaces.
Fire ant mounds establish quickly in Stone Oak yards, particularly after summer rains. Children’s play areas, sidewalks, and landscaping beds require consistent quarterly treatment. Safe for kids and pets once the application dries completely.
