Fire ants thrive in the warm, humid climate of Katy, TX, building mounds in lawns, flower beds, and along sidewalks. Unlike many household pests, fire ants are an outdoor threat that can turn a yard, playground, or patio into a hazard — their sting is painful, and for some people, dangerous.
Because fire ant colonies can quickly spread across a property and rebuild after a disturbed mound, getting rid of them usually takes more than a single store-bought treatment.
Signs that fire ants have moved into your Katy yard include:
- Dome-shaped dirt mounds in the lawn, often near sidewalks, patios, or the base of trees
- Mounds that appear suddenly after rain, when ants move closer to the surface
- Aggressive swarming when a mound is disturbed
- Painful, burning stings that leave small white blisters
- Reddish-brown ants about 1/8 to 1/4 inch long, smaller than most other ant species
If you notice mounds appearing in multiple areas of the yard, it's a sign of an established colony rather than a single isolated nest.
Fire ants attack in groups, often stinging multiple times within seconds of a mound being disturbed. For most people, this means painful welts that itch and burn for several days. For children, pets, and anyone with a sting allergy, fire ant encounters can be far more serious, sometimes requiring medical attention.
This is one of the main reasons fire ant control isn't something to put off — especially in yards where kids or pets spend time outdoors.
How Professional Fire Ant Control Works
Katy Pest Pros treats fire ant infestations in Katy using a two-part approach:
- Broadcast bait treatment across the lawn, which worker ants carry back to the colony and queen, eliminating the nest from the inside out
- Direct mound treatment for active or visible mounds, for faster knockdown of aggressive colonies
This combination controls existing mounds while also preventing new colonies from establishing elsewhere on the property — something DIY mound-by-mound treatments usually miss.

Mound-killer powders and home remedies can knock down a single visible mound, but fire ant colonies often have satellite nests connected underground that never get treated. Disturbing a mound without eliminating the queen can even cause the colony to split and spread further across the yard.
Professional treatments are formulated to reach the entire colony, including nests that aren't visible above ground, which is why professional fire ant control tends to last far longer than DIY options.
Most Katy properties benefit from fire ant treatments every 60 to 90 days, since new colonies can move in from neighboring yards or undeveloped land at any time. Pairing fire ant control with a broader perimeter pest control plan helps keep both the yard and the home itself protected year-round.
Katy Pest Pros provides fast, effective fire ant control throughout Katy, TX, knocking down active mounds and treating colonies at the source so they don't come back. Call (281) 888-8888 today to schedule a free yard inspection.
