Our Story

Built on Honest Work

Andre Castillo started Alamo Pest Defense after 8 years as a route tech for a national pest brand. Frustrated by the upsell-heavy playbook and the rotation of unfamiliar techs at every visit, he built Alamo around three principles: a licensed applicator on every job, real exclusion work over endless re-baiting, and a re-treat policy customers can actually use without a fight. Fifteen years and 170+ five-star reviews later, the playbook holds.

Our Values

What We Stand For

Exclusion, Not Just Spray

We seal entry points and remove conducive conditions. Spraying alone is a treadmill — fixing the access is what keeps pests gone.

Pet & Child-Safe Products

Onslaught and Termidor applied per label, dry within 30 minutes. We use bait gel inside, not fogging. Safe and effective.

Real Re-Treat Policy

See activity between visits? We come back free, no questions, no fee. That's the deal — and we honor it.

Licensed Applicator On Every Job

Every tech holds a Texas TDA Commercial Applicator license. No rotating subcontractors, no untrained helpers sent alone.

Certifications & Credentials

Every credential required to service your home safely and legally.
