McKinney's sunny lawns and irrigated beds are prime ant real estate. From early spring through fall, you may see mounds in the grass, columns marching up the wall, or large black ants cruising across the kitchen at night. Treating them effectively means figuring out what you have and where it nests.
Ant species around McKinney and Collin County
- Red imported fire ants mound in open grass, along sidewalks and near irrigation boxes, and they sting aggressively.
- Pavement ants nest under driveways, walkways and slabs.
- Odorous house ants trail along baseboards after rain.
- Carpenter ants excavate moist wood in old trees, stumps and houses with leaks.
- Texas leafcutter ants strip leaves from shrubs and trees in some parts of the state, though they are more of a concern farther south and east.
- Rover ants and crazy ants are small, fast-moving ants that sometimes appear in homes during warm months.
Local conditions that fuel colonies
Expansive clay soil, hot summers and irrigation produce the steady moisture ants prefer. Newly laid sod in subdivisions like Stonebridge Ranch, Craig Ranch and Tucker Hill invites fire ants almost immediately. Mature trees around downtown and the historic districts host carpenter ants, especially if branches are decayed or if a roof leak has left wood damp. When a heavy rain saturates a lawn, colonies seek high ground, which can mean the inside of your house. In August, dry spells send them toward bathroom and kitchen water sources. Gaps between brick and slab, around garage doors and along utility lines let them in unnoticed.
When to worry
Occasional stray ants are normal. Call for help when you see a persistent trail that returns after cleaning, mounds appearing in several places, sawdust-like debris from wood, winged ants inside, or stings affecting children or pets. Fire ant mounds near play areas or pet runs deserve quick attention.
Professional treatment methods in McKinney
- Identify the species and trace trails to nests and entry points.
- For fire ants, apply broadcast bait across the lawn and treat individual mounds if needed.
- Indoors, place gel or granular bait along trails and in voids where ants forage.
- Apply non-repellent products around the foundation so ants carry them back to the colony.
- For carpenter ants, locate the nest and treat it directly, and advise on fixing the moisture source.
What McKinney homeowners can do
Keep food covered, clean spills quickly and store pet food in lidded containers. Point sprinklers away from the foundation and reduce mulch depth. Remove debris, stumps and rotted wood. Trim vegetation off the roof and walls. Seal cracks around windows, doors and pipes. Do not spray repellents over an active trail before a technician visits, because it can disrupt baiting.

Are fire ants worse after rain?
They are more visible, since flooded colonies build new mounds and move to higher ground.
What should I do for a fire ant sting?
Wash the area and apply a cold pack. Seek medical help if swelling, breathing trouble or dizziness develops.
Do ants cause structural damage?
Carpenter ants can, over time. Other species are mostly nuisances.

Many baits take days to weeks to affect the colony.
