Year-Round Protection Against South Texas Pests
Look, living in McAllen means dealing with pests that don’t take a vacation. While other parts of the country get a break when temperatures drop, we’re dealing with roaches, ants, and spiders 365 days a year. That’s just life in the Rio Grande Valley.
At Colco Pest and Weed Control, we’ve been protecting McAllen homes and businesses from the full lineup of South Texas pests for years. We’re a family-owned operation, which means when you call, you’re not getting shuffled through some corporate call center—you’re talking to people who live here and deal with the same pest pressures you do.
Special Offer: Free inspection for new customers. Call us at 956-777-6328 or schedule online.
Why McAllen Has Year-Round Pest Problems
Here’s the deal—our subtropical climate is basically a pest paradise:
No Winter Die-Off: Most places get a hard freeze that knocks pest populations back. McAllen? Our “winter” barely dips below 50°F. Pests just keep breeding straight through December and January.
Constant Humidity: We’re averaging 60-75% humidity most of the year. Cockroaches, especially those big American roaches (palmetto bugs), absolutely thrive in moisture. They need it to survive, and we’ve got plenty.
Agricultural Proximity: The McAllen is one of the most productive agricultural regions in Texas. All those citrus groves, vegetable farms, and crop fields create massive pest populations that eventually make their way into residential areas.
Older Housing Stock: Many McAllen homes were built in the ’70s and ’80s. Foundation cracks, gaps around pipes, worn weatherstripping—these older structures give pests dozens of entry points.
Urban Heat Islands: Concrete, asphalt, and buildings hold heat. Downtown McAllen and developed areas stay warmer longer into the evening, which keeps insects active and breeding longer each day.
Proximity to Mexico: We’re 10 miles from the border. Pest populations don’t respect international boundaries—species common in Reynosa are common here too, and vice versa.
Standing Water After Storms: Summer thunderstorms drop 2-3 inches in an afternoon. Poor drainage in older neighborhoods creates breeding grounds for mosquitoes within 48 hours.
What We Control
Cockroaches – Both the big American roaches that come in from outside and the smaller German roaches that breed inside your home. German roaches are the serious ones—if you see them during the day, you’ve got hundreds hiding in your walls and cabinets.
Ants – Fire ants in your yard, crazy ants that swarm electrical equipment, and sugar ants trailing through your kitchen. Each species needs different treatment approaches.
Spiders – Black widows love stacked firewood and storage areas. Brown recluses hide in boxes and closets. We also handle the harmless but annoying wolf spiders and jumping spiders.
Fleas & Ticks – If you’ve got pets or wildlife visiting your property, you’ve probably got fleas. Ticks are less common in urban McAllen but show up in properties near brush areas.
Mosquitoes – Standing water in birdbaths, clogged gutters, flower pot saucers—mosquitoes only need a bottle cap of water to breed. We treat the breeding sites, not just spray adults.
Silverfish – These little bugs love humidity and paper products. Bathrooms, closets, bookcases—anywhere it’s damp and dark.
Crickets – They’re loud, they attract scorpions (which eat them), and they’ll chew holes in fabrics. More of a problem in fall when they’re looking for warm spots.
How Our General Pest Control Works
We’re not just showing up and spraying baseboards. Here’s what actually happens:
Step 1: Property Inspection (15-20 minutes) We walk your property—inside and out. We’re looking for active pest activity, entry points, moisture issues, and conditions that attract pests. You’ll get honest feedback about what we find.
Step 2: Customized Treatment Plan Every property is different. A house near the resacas needs different treatment than a newer home in west Rio Grande Valley. We tailor the approach based on what you’re dealing with and what your property conditions are.
Step 3: Interior Treatment We treat cracks, crevices, baseboards, and problem areas with products that are safe for your family and pets once dry. We focus on where pests hide and travel—not just visible surfaces.
Step 4: Exterior Perimeter Barrier This is the big one. We create a barrier around your foundation, windows, doors, and other entry points. When pests cross it, they pick up product and take it back to their hiding spots. This knocks down entire populations, not just individual bugs.
Step 5: Yard and Landscape Treatment Fire ant mounds, spider webs under eaves, ant trails along fences—we treat the outdoor sources so pests don’t make it to your house in the first place.
Step 6: Follow-Up Monitoring Pest control isn’t one-and-done. We come back quarterly (or monthly if needed) to maintain protection and address any new activity.
Our Tri-Vor-Guard Protection System
We use a three-layer defense approach:
Layer 1 – Exclusion: Identifying and recommending ways to seal entry points Layer 2 – Elimination: Treating active infestations with targeted products Layer 3 – Prevention: Creating barriers and ongoing monitoring to keep pests out
This isn’t just marketing speak—it’s how we actually work. You need all three layers working together for long-term control.
Areas We Serve in Rio Grande Valley
We also serve surrounding communities throughout the Rio Grande Valley. If you’re not sure if we cover your area, just call—chances are we do.

Licensed by Texas Department of Agriculture: We’re not some guy with a pickup truck. We’re fully licensed, insured, and trained.
Honest Recommendations: If you don’t need monthly service, we’ll tell you. If quarterly is enough, we’ll say so. We’re not here to oversell you.
Teacher and Military Discounts: We take care of the people who take care of our community.

Posted on TakerJoes2025-10-07Trustindex verifies that the original source of the review is Google. I can’t say enough good things about Colco Pest and Weed Control! I had a pest issue that was driving me crazy, and they completely took care of it. From the moment they arrived, they were friendly, professional, and really knew their stuff. They inspected everything carefully, explained what was causing the problem, and treated every spot with precision. Within just a few days, I noticed a huge difference the pests were completely gone in all areas except 1, so i called back and let them know about it and they immediately took care of the issue. What impressed me most was how respectful and detail-oriented they were, making sure the job was done right and that I was satisfied before leaving. It’s rare to find a company that actually takes pride in their work they do now a days. If you’re in the McAllen to La Joya area and need reliable pest control, don’t waste time calling anyone else these are the people to go with. 100% recommend! Better yet I'm gonna call back right now so they can also treat the ugly weeds outside.Posted on Cristina Espinoza2025-09-12Trustindex verifies that the original source of the review is Google. Cody with Colco was very informative with explaining what he would need to do for the issue I had for indoor and outdoor pests - specifically for German roaches and fleas in the yard.
