Ant Control in San Antonio
From fire ant mounds in the yard to trails marching across the kitchen counter, ants are one of San Antonio's most persistent pests. Mosquito Guard Pro, a division of Bob Jenkins Pest Control Inc., goes after the colony, not just the trail.
Ant Control built for San Antonio homes
Quick answer
How do I get rid of ants in my San Antonio home for good?
You have to reach the colony, not just the ants you see. Spraying a trail kills the visible workers but leaves the queen and nest producing more, which is why the line is back the next day. Mosquito Guard Pro treats in a way that goes after the colony itself, so the source is eliminated and the trail doesn't just return.

The ants San Antonio homeowners call about
South-Central Texas has a deep bench of ants. Red imported fire ants build mounds across yards and deliver a painful sting, odorous house ants and tiny sugar ants stream indoors after sweets and moisture, and tawny crazy ants swarm in erratic, fast-moving masses that can overwhelm a property.
Our long warm season keeps colonies active most of the year, and many local ants nest outdoors and forage inside, so the problem on your counter usually traces back to a colony in the yard or wall void.
Why spraying the trail doesn't work
When you spray a trail of ants, you kill the workers you can see, but the colony, with its queen and brood, is somewhere else entirely. Worse, some ant species respond to being sprayed by budding, splitting into multiple colonies, which makes the problem bigger.
Real ant control reaches the colony at the source so the whole nest is dealt with, which is why a trail keeps coming back after store-bought sprays but stops after a proper treatment.
How our ant control works
A technician identifies the ant species, because the right approach for fire ants in the yard is different from the right approach for sugar ants in the kitchen, then traces the activity back to where the colony is nesting.
From there we treat to reach the colony and put a barrier in place around the home, so the source is addressed and new trails are kept from forming. We'll also point out the moisture and entry points drawing them in.
Because ants are relentless in this climate, most homes do best with ongoing protection. We'll recommend the right cadence for your property, no flat-rate pressure.
