Welcome

Start reading the technical brief regarding the 2026 Formosan termite surge in South Texas. This document provides data for homeowners in Pearsall, Dilley, Cotulla, and Devine. Review the following five critical points to understand the current threat level and available mitigation strategies.

1. Identify the Formosan Swarmer Specimen

Identify the specific biological characteristics of the Coptotermes formosanus. Formosan termites are subterranean. They are aggressive. They differ from native subterranean species found in Medina and Frio counties.

Visual Characteristics

Observe the color. Formosan swarmers are tan or yellowish-brown. Native subterranean termites are typically black or dark brown. Examine the wings. Formosan swarmers have wings with two heavy veins on the leading edge. They are covered in fine hairs.

Swarming Behavior

Monitor light sources. Formosan termites swarm at night. They are highly attracted to artificial light. Native species typically swarm during daylight hours. Check window sills and porch lights. Collect discarded wings for identification.

2. Analyze the 2026 Surge Timeline

Track the seasonal data. The 2026 surge follows a specific pattern. The "Mother’s Day" window is the peak activity period. This occurs from April through June.

Environmental Triggers

Monitor local weather stations. Swarms occur on warm, humid evenings. Activity increases after significant rainfall. The humidity levels in South Texas during June 2026 are optimal for colony expansion.

Geographic Spread

Verify the location data. Formosan termites are established in Bexar County. They are moving south along the I-35 corridor. Homeowners in Devine and Pearsall must increase surveillance. The movement into La Salle County (Cotulla) and further into Dilley is documented via transport of infested materials.

3. Assess Local Risk Factors in South Texas

Evaluate the proximity to high-risk zones. Pearsall, Dilley, Cotulla, and Devine are within the expansion radius.

Material Transport

Inspect landscape materials. Formosan termites often spread through recycled railroad ties. They inhabit shoring timbers. If you recently purchased lumber or mulch, conduct a visual inspection.

Structural Vulnerability

Review foundation types. Slab-on-grade homes are susceptible. Mud tubes are the primary indicators. These tubes allow termites to travel while maintaining moisture. Inspect the exterior slab line every 30 days.

4. Understand the Speed of Destruction

Quantify the damage potential. Formosan colonies are larger than native colonies. A single colony can contain several million individuals.

Consumption Rate

A mature Formosan colony can consume significant amounts of wood in a short period. They damage structural timbers, flooring, and even wallpaper. Do not ignore signs of "blistering" paint. This often indicates termite activity beneath the surface.

Professional Intervention

Contact Salinas and Sons Pest Control for a technical assessment. We are a family-owned operation. We understand the South Texas landscape. We provide Specialized Termite Treatments designed for high-density colonies.

5. Implement Prevention and Treatment Protocols

Apply the following preventive measures immediately.

Moisture Control

Eliminate standing water. Check air conditioning drain lines. Ensure they discharge away from the foundation. Fix leaking outdoor faucets. Formosan termites require constant moisture sources to survive.

Yard Maintenance

Clear debris. Remove dead trees and stumps. Keep mulch at least six inches away from the foundation. Maintain a clear "inspection zone" around the perimeter of the structure.
