Ants do well on the high plains, even if they are not the first insect most people associate with Wyoming. Cheyenne's dry grassland soils are home to native mound-building ants, its irrigated lawns attract pavement ants, and its older trees and fences occasionally host carpenter ants. When the spring sun warms the pavement, the colonies come alive, and by June many residents are fighting a line on the patio or a swarm in a flower bed.
PestMinistry is a referral service. We connect callers with independent, licensed ant control providers serving Cheyenne. We do not treat homes ourselves.
What kinds of ants?
- Pavement ants are small and dark and live under slabs, driveways and walkways. They are the most common household ant on the plains.
- Thatching ants build conspicuous domed mounds of grass and twigs in lawns and prairie edges, and bite if disturbed.
- Harvester ants keep bare, circular patches on open ground and sting, mostly in undeveloped lots and rangeland on the city's fringe.
- Carpenter ants are present where trees and damp wood exist, though less widespread than in forested regions.
- Odorous house ants invade kitchens in search of sweets and can be hard to dislodge.
Water in a dry place draws ants
Sprinklers, drip lines, leaking faucets and areas where snow melts against foundations create moist pockets in an otherwise arid setting. Ants move toward them. Homes with lawns along the older streets near Holliday Park and in newer subdivisions with green yards can see steady ant traffic from May through September. Flat roofs and old window wells that collect water also appeal to carpenter ants.
What a Cheyenne provider will do
- Identify the species. A mound in the grass calls for a different response than a trail inside.
- For kitchen invaders, place baits near trails and avoid wiping away the scent trail that leads workers to the bait.
- Apply targeted exterior products to nests, edges of slabs and along foundations.
- Advise on moisture, mulch depth and sprinkler positions.
- Check back to confirm the activity has ceased.
Simple prevention around Cheyenne yards
- Adjust sprinkler heads away from foundations and siding.
- Keep stored firewood and lumber off the ground and away from the wall.
- Seal cracks where ants line up, particularly at doors and window sills.
- Wipe up juice, honey and pet food residue promptly.
- Cut back vegetation touching the house.
- Rinse recyclables and keep trash lids tight.
Calendar
Expect first trails in April or May, then winged ants after a warm rain in summer. By August, ants forage heavily on sweet foods, which can overlap with wasp season. As nights cool in September, some ants head indoors. In winter, any indoor trail suggests a nest somewhere in the building, rather than outside.

Frequently asked questions
Are the mounds in my lawn dangerous?
Thatching ant mounds are not harmful to the house but their bites can be painful. A provider can treat them if they are in play areas.
Why are ants all over my patio?
Pavement ants nest beneath the slab and forage along cracks. Baiting usually solves it.
Will freezing temperatures kill the colony?
Outdoor colonies go deep and survive. Indoor ones are not affected.
Do ants hurt my house?
Most do not. Carpenter ants in damp wood are the exception, so look for frass and softened trim.
