Testimonials
“Roaches had taken over our kitchen after the neighbor's renovation. Andre's tech did the initial knock-down treatment and a follow-up at no charge two weeks later. Haven't seen a single one in six months. Quarterly plan is worth every penny.”
Jennifer R.
Alamo Heights, TX
“Scorpion problem in the garage and under the deck. Alamo did a full perimeter treatment and sealed entry points along the foundation. Counted zero scorpions this season — first summer in three years we can let the dog out at night.”
Mark & Lisa T.
Stone Oak, TX
“On quarterly service for two years. Same tech every visit, in and out in 30 minutes, gives me a real inspection report. They caught early termite activity on the back fence before it got near the house. Honest crew — no upsells.”

The Person Behind the Company
Owner & Licensed Applicator · License #TX-TDA-0782115
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.
"Get pests out and keep them out — with products that are safe for the people living there."

The questions clients ask before they pick up the phone.
Standard home (1,500-2,500 sqft) on quarterly: $89-119 per visit, no setup fee, cancel anytime. Larger homes and acreage are quoted individually.
Yes. Our standard products (Onslaught FastCap, Termidor SC) are pyrethroid-based and dry within 30 minutes. Once dry, they're safe for pets and kids. We use bait gel inside cabinets — also safe, sealed in the gel.
You call us, we come back free. The residual takes 7-14 days to fully cycle through a colony. If you see activity after 14 days, that's on us — free re-treat, every time.
