San Antonio at a glance

San Antonio is the seventh-largest city in the United States and the second-largest in Texas. It sprawls across Bexar County from the South Texas Plains up to the southern edge of the Hill Country, bisected by the Balcones Escarpment — the geological feature that divides the rocky hills, springs, and canyons of the Texas Hill Country in the north from the Blackland Prairie and South Texas Plains in the south. The San Antonio River rises from springs just north of downtown and flows southward through the city, eventually making its way to the Gulf.

For stinging-insect purposes, San Antonio is not one ecology — it's two. North of Loop 410, the limestone cuts and native scrub produce pest pressure that behaves more like Boerne or the Hill Country than like a typical South Texas city. South of 410, the coastal plain soils and denser urban fabric produce a different pressure profile entirely. Every experienced pest control technician in Bexar County learns to read this geography before they pull up to a job.

A quick history

The Spanish named the area "San Antonio" in 1691, when a missionary expedition arrived on the feast day of Saint Anthony of Padua. On May 1, 1718, Martín de Alarcón formally established Mission San Antonio de Valero — which would be secularized in 1793 and later become famous as the Alamo. The Presidio San Antonio de Béxar was founded four days later, on May 5, 1718, on the west side of the San Antonio River.

In 1731, 55 Canary Islanders arrived and established the Villa de San Fernando de Béxar, becoming the first chartered civil settlement in present-day Texas. Four more missions were added along the river south of the original. All five missions — Valero (the Alamo), Concepción, San José, San Juan Capistrano, and Espada — are today a UNESCO World Heritage Site, the only one in Texas.

The city passed through the Spanish Empire, then the Mexican Republic (1821–1836), then the Republic of Texas, then statehood in 1846. The Battle of the Alamo in 1836 and the subsequent Mexican-American War (1846–1848) were brutal — the city's population was reduced by nearly two-thirds, down to about 800 residents by the war's end. The city then rebuilt through a massive wave of German immigration, to the point that German speakers outnumbered both Tejanos and Anglos in San Antonio until 1877.

Tejanos lost majority status in the city in 1850 and did not regain it until 1968. Today, Bexar County is 59.3% Hispanic as of 2020, Texas's most populous majority-Hispanic county and the third-largest such in the nation.

Geography, ecology, and why it matters for stinging insects

San Antonio sits directly on the Balcones Escarpment, which explains the city's split pest personality:

North of 410 (limestone Hill Country transition):

• Cedar-oak scrub and exposed limestone
• Shallow soils with rock outcroppings
• Wooded lots in newer custom-home subdivisions
• Greenbelt corridors running through subdivisions (Edwards Aquifer recharge zone requirements)
• Higher populations of paper wasps, yellowjackets in ground nests, feral honey bees in rock cavities, carpenter bees on cedar fascia, and increasingly tarantula hawks along the northwest edge

South of 410 (coastal plains, older urban fabric):

• Deeper alluvial soils
• Denser building footprints
• Established live oak canopy in older neighborhoods
• Heavy paper wasp, red wasp, and structural honey bee pressure in historic masonry buildings
• Fire ant pressure is universal

The San Antonio River rises from springs north of downtown and runs through the heart of the city. The Riverwalk is the tourism landmark, but for pest control the river corridor matters because it generates consistent moisture, which supports mud dauber populations, paper wasps, and cicada killers throughout the summer.

San Antonio surrounds several independent enclave cities — communities that refused or predated annexation and retained independent municipal government. These include Alamo Heights, Balcones Heights, Castle Hills, Hill Country Village, Hollywood Park, Kirby, Leon Valley, Olmos Park, Shavano Park, and Terrell Hills. Pest Trappers services all of these enclaves. Each has its own code enforcement and its own quirks — Alamo Heights homeowners care especially about visible nests on historic masonry; Terrell Hills, about eave-level paper wasps on the 1920s-1940s ranch homes; Shavano Park, about aerial hornet nests in mature oak canopies.

San Antonio neighborhoods — pest pressure by area

Alamo Heights / Olmos Park / Terrell Hills — Mature live oaks, 1920s-1940s historic homes, limestone retaining walls. The architecture is exactly what every stinging-insect species prefers. Wall-void honey bee colonies in historic limestone and red wasp attic infestations are our two most common calls here.

Monte Vista / Tobin Hill / King William — Older masonry and stucco homes, Victorian and Craftsman historic architecture. Paper wasps on deep eaves and red wasps in attic voids are the signature service.

Stone Oak / 281 N corridor (78258, 78260, 78261) — Master-planned newer construction with greenbelts and drainage easements built into the subdivisions (Edwards Aquifer recharge zone requirements). The greenbelts are exactly why Stone Oak has the heaviest yellowjacket ground-nest density in the entire metro.

The Dominion / Leon Springs (78257) — Custom homes on wooded lots with TPC/La Cantera golf proximity. See separate Leon Springs town page — this area behaves ecologically more like Boerne than like central San Antonio.

Shavano Park / Hollywood Park — Established canopy, larger lots, 1960s-1980s custom homes. Carpenter bees on cedar fascia and paper wasps on high eaves.

Alamo Ranch / Far West SA (1604 W corridor) — Newer builds from the 2000s-2010s in a scrub-cedar transition zone adjacent to Government Canyon. High fire ant pressure, tarantula hawk sightings in summer, and standard paper wasp workload.

Downtown / King William / Southtown / Dignowity Hill — Limestone and masonry historic buildings with roof access challenges. Red wasps and feral honey bee cavity nesting in historic buildings are recurring.

South Side / Mission Trail area / Harlandale — Working-class neighborhoods with smaller lot sizes, heavy fire ant pressure, paper wasps on carports and fence rails, and the occasional honey bee swarm.

Northeast / Windcrest / Kirby / Converse / Schertz corridor — Suburban edges, more consistent fire ant pressure, and yellowjacket issues in greenbelt areas of newer developments.

Seasonal pattern

San Antonio's stinging-insect cycle runs nearly year-round because winters are mild enough that structural honey bee colonies and indoor yellowjacket populations stay active:

• Feb–Mar: Paper wasp queens emerge from overwintering sites. Honey bee colonies begin brood expansion. First prevention window of the year.
• Apr–Jun: Honey bee swarm season peaks. Paper wasp nest construction peaks. Carpenter bees drilling. CPS Energy meter-box bee swarm calls spike.
• Jul–Sep: Yellowjacket ground-nest season in greenbelts. Cicada killer season in sandy soils. The highest sting-incident window of the year — most ER visits for stings happen here.
• Oct–Nov: Yellowjackets still dangerous (colonies peak in late September–early October). Paper wasp queens begin seeking overwintering sites in attics, siding gaps, and shutter cavities.
• Dec–Jan: The only true slow period — but structural honey bee colonies remain active year-round inside walls, and fire ants still forage during warm afternoons.

Why Pest Trappers for stinging insects in San Antonio

Pest Trappers is a family-owned and operated San Antonio pest control company, headquartered at 7319 Brandyridge in San Antonio (78250). Owner-operator Travis Lambert runs the company himself — when you call 210-281-1064, you're calling the person who runs the business, not a call center. The company has been serving San Antonio and the surrounding area for nearly a decade.

For stinging insects specifically, San Antonio is not a service area where you can apply a one-size-fits-all treatment. Paper wasp calls in Alamo Heights limestone look nothing like yellowjacket calls in Stone Oak greenbelts, which in turn look nothing like feral honey bee swarm calls on a CPS meter box in King William. Pest Trappers services all of it — residential, commercial, emergency response, and scheduled prevention — across the entire 412-square-mile city and all the surrounding enclave cities.

The company is licensed, insured, and Latinx-owned. We're not on a national route — San Antonio isn't a stop between Austin and Houston for us. It's home.

Odd, funny, and genuinely true about San Antonio

• The Alamo's original Spanish name was Mission San Antonio de Valero. The "Alamo" nickname came later — alamo is Spanish for cottonwood, a reference to the cottonwood trees that grew around the mission, not the battle. It was officially secularized in 1793 and became a military post decades before its 1836 fame.
• San Antonio was the largest town in Texas — ahead of Galveston — in 1860, with a population of 8,235. This is often a surprise to anyone who assumes Houston or Dallas always held the top spot.
• German speakers outnumbered both Tejanos and Anglos in San Antonio until after 1877. The city has a genuine German heritage that mostly got absorbed into Texas-German culture before most modern residents ever noticed it.
• Tejanos lost majority population status in 1850 and did not regain it until 1968 — a span of 118 years. Juan Seguín, Alamo defender and mayor of San Antonio, was the last Tejano mayor for almost 150 years after being forced out of office by political opponents in 1842.
• San Antonio is the first chartered civil settlement in present-day Texas (1731, when the 55 Canary Islanders arrived and founded Villa de San Fernando de Béxar). Before that, the area held military and mission settlements, but not a chartered civil municipality.
• The five Spanish Missions (Valero, Concepción, San José, San Juan Capistrano, Espada) are collectively a UNESCO World Heritage Site — the only UNESCO World Heritage Site in Texas. Added to the list in 2015.
• Bexar is pronounced "BAIR" or "BAY-er," never "BEKS-ar." The name comes from San Antonio de Béjar, the original Spanish name for the settlement, which in turn came from the family name of the Duke of Béjar (a town in Spain). Non-Texans guessing at the pronunciation for the first time get it wrong almost universally.
• The population was reduced by almost two-thirds during the Mexican-American War, to just 800 residents by its end. The city then rebuilt entirely through immigration, primarily German.
• San Antonio hosts over 100,000 college students across 31 higher-education institutions, including UTSA, UT Health San Antonio, Texas A&M-San Antonio, Trinity University, St. Mary's University, Our Lady of the Lake, University of the Incarnate Word, Palo Alto College, Northwest Vista, San Antonio College, and others.
• Fort Sam Houston (1879) has been inside the city since before most of the modern city existed. It's the headquarters of the U.S. Fifth Army and home to the Army's Academy of Health Sciences, the basic school for military medical personnel.
• The San Antonio River rises from springs north of downtown — the same springs that the Payaya Indians called "Yanaguana" long before the Spanish arrived. The Payaya encampment at the springs is what the 1691 Spanish expedition first encountered when they arrived on the feast day of Saint Anthony and gave the area its current name.
• The city surrounds several enclave cities — Alamo Heights, Castle Hills, Hill Country Village, Hollywood Park, Kirby, Leon Valley, Olmos Park, Shavano Park, Terrell Hills, and Balcones Heights. These communities either incorporated before San Antonio annexed the surrounding land, or successfully resisted annexation afterward. Driving through San Antonio, you regularly cross city lines without realizing it.
• The Balcones Escarpment runs directly through the city. You can literally stand at one spot on the north side of town and look south across what amounts to two different ecoregions — Hill Country to the north, Coastal Plain to the south. This has real consequences for plant life, insect populations, and even weather patterns.
• San Antonio is roughly 150 miles from the Mexican border. The city's culture has always been a blend of Mexican and Texan, and about three-fifths of the population is of Hispanic descent as of the most recent census.
• On September 14, 2013, Bexar County opened BiblioTech — the nation's first fully bookless public library. Every book is digital.
