ANTS
How we exterminate ants—the workers, the queen, and the colony.
Get a fast response and a thorough on-site inspection to determine the severity of the ant infestation. Once we know what we’re dealing with, we place bait at key points throughout your home and property where ants enter and leave.
- Evaluate the extent of the infestation.
- Deploy kid and pet-safe chemical compounds that attack the ant's central nervous system and eliminate the queen.
- Secure all entry points with repellent to prevent reentry.
Colt Pest Control technicians were here when the first waves of invasive fire ants entered the region, so we hold a little bit of a grudge and take pride in tracking, locating, and decimating these insects—because no one invited ‘em. Colt Pest will always protect your property with preventative measures that keep out ants for good.

RODENTS
How we exterminate intelligent rats and mice at a low cost.
Just because your home is relatively new doesn’t mean it’s immune to rodents. Rats and mice will enter your home through cracks, holes, vents, and gaps—they need someplace dry, cool, or warm (depending on the season), and safe. We’re fast and effective because we focus inspections on points of entry.
- Conduct an inspection to identify entry and exit points, some large and some as small as a quarter.
- Place scented bait in tamper-proof bait boxes.
- Clear rodents and mice remains quickly after death.
If you’re the type of homeowner who likes to be proactive and aggressive with D.I.Y. methods, we’ve got nothing but respect for you, but the truth is that your time is best spent on doing the work that provides for your family. Skip the trip to the home improvement store. Bring in professionals who know how to exterminate rats and mice quickly and efficiently.

TERMITES
How we exterminate termites, eliminate severe infestations, and install cost-effective solutions for long-term protection.
Texas is one of the top three states at risk for termite infestation, and delaying termite treatment and control is a recipe for structural damage to floors, walls, ceilings, and even your foundation.
- Conduct an inspection anywhere there are sources of organic fiber (wood), evaluate the damage, and locate the source of the infestation, including potential entry points in the foundation.
- Mild-to-Moderate Infestations: For moderate infestations, a combination of deterrence (laying diatomaceous earth around the home) and extermination (with liquid or foam termiticides, boric acid, vinegar, and other people and pet-safe chemicals) is going to kill the termites and keep your property safe.
- Severe Infestations: For severe, drywood infestations, direct wood treatment is necessary, ranging from heat treatment to fumigation.
Prevention and deterrence are critical to keeping your home and property termite-free. That’s why every termite extermination job ends with the placement of baiting and monitoring stations at key points beneath and around your home. Talk to your technician, and we’ll find a solution that fits your budget.
