Odorous house ants and rover ants are small trailing ants that enter Plano homes after rain or heat in search of moisture and sweets. A technician finds the trail and the nest, uses slow-acting baits instead of repellent spray, and treats the exterior. Plano Pest Control serves Collin County, and the price is approved before work begins.
The ants that bother most Plano kitchens are not the ones that bite. They are tiny, dark and quick, they travel in tidy lines along a countertop edge, and they seem to arrive overnight. Two species account for much of it: the odorous house ant, which gives off a rotten-coconut smell when crushed, and the rover ant, a very small, uniformly dark ant that wanders in loose, irregular paths rather than a single file.
Both are mainly a nuisance. They do not damage structural wood the way termites do, and they are not the stinging mound builders you see in a lawn. If the mounds are what you are dealing with, that is a different job and a different product, covered under fire ant control. If the ants are big and coming out of wood, see carpenter ant control. This page is for the small trailing ants in the kitchen, the bath and along the baseboard.
Tight-lot subdivisions make the problem easy to start. When houses sit close together, mulch beds, irrigated turf and shared fence lines put several colonies within a few feet of every wall. A technician from the licensed local company who answers a call to Plano Pest Control starts by working out where the trail comes from, because spraying the line you can see rarely touches the nest.
Do not spray repellent aerosols or pour household cleaners near bait stations, and do not mix products you bought yourself with what the technician applied. Keep children and pets away from baits and treated surfaces, and ask the technician about precautions for your home.
The technician asks where and when you see the ants, then follows the trail to the entry point, checking window frames, plumbing penetrations, weep holes in the brick and the garage door seal.
Odorous house ants, rover ants and a few others look alike to most of us but eat and nest differently. A quick identification decides which bait goes down and how often it needs to be checked.
Slow-acting gel or liquid baits go along trails, not on top of them, so foragers carry the active ingredient back to the colony. Wiping away trails and spraying repellent over bait stations defeats the purpose.
A labeled residual product goes around the foundation, door thresholds and window frames. Mulch, ground cover and any nest sites in turf or under pavers get attention too.
You get a written report and plain advice about moisture, food storage and shrubs touching the siding. Ant activity often rises for a few days as baits are taken, then drops.
Ant work does not have one flat price, and any number quoted before someone looks at the house is a guess. These are the things that move the quote.
| Job | Typical range | What it includes |
|---|---|---|
| Home size and number of entry points | Set after the inspection | a larger house or a long fence line takes more time and product |
| Interior baiting plus exterior treatment | Quoted as one visit or a plan | single visit for a flare-up, recurring visits if ants return each season |
| Species and number of colonies | Explained on site | a persistent supercolony-type problem may need follow-up checks |
No price is fixed until the technician has looked at the house, and nothing is applied until you have heard the price and approved it.
Heavy rain floods nests in turf and mulch, and colonies move toward drier, protected spaces such as wall voids behind a kitchen. Dry, hot spells do the opposite, sending ants toward the moisture in sinks and dishwashers. Either swing can start a trail, which is why ants often appear within days of a weather change.
North Texas swings between the two. Annual rainfall runs roughly 35 to 38 inches, and the Dallas-Fort Worth area averages about 17 days a year at or above 100 degrees, on records kept at DFW Airport. A colony can be flooded out one week and dried out the next, and the house is the one steady, sheltered, watered place nearby.
That is also why a single treatment does not always end it. If the weather pushes new ants toward the house every few weeks, the exterior needs a fresh barrier and the baits need a second look.
Repellent sprays kill the foragers you see but scatter the rest. Odorous house ants in particular can split a colony into several smaller ones when disturbed, and a sprayed trail simply moves. Baits work the other way: the ants carry the active ingredient home slowly, so the nest is reached before the trail disappears.
For the first few days after baits go down, you may see more ants, not fewer. That means they are feeding. Resist the urge to wipe the bait away or spray the line. If activity is still heavy after about two weeks, call back so a technician can check whether the bait is the right match or whether another colony is feeding nearby.
A good habit during treatment: wipe up sweets and crumbs, store pet food in a sealed container and fix drips, but leave the bait stations alone.
Odorous house ants are dark brown to black, about an eighth of an inch long, and follow clear trails to sweets; crushed, they smell like rotten coconut. Rover ants are even smaller, uniformly dark and wander erratically. Both nest in soil, mulch and wall voids, but they favor different foods, so the bait choice matters.
Both feed on honeydew, the sugary waste of aphids and similar insects on shrubs and trees, which is one reason a thick bed of ornamental plants beside the wall helps them. Rover ants are often found around leaky plumbing and in damp mulch, and they can be slow to take certain baits.
A technician may place two different baits at once to find out which one the colony prefers. That is normal, and it is faster than guessing one at a time.
Keep mulch pulled back from the foundation, trim shrubs and tree limbs so they do not touch the house, and fix leaks around hose bibs and sprinkler heads. Ants use branches and fences as bridges. Fewer bridges and less standing moisture near the slab means fewer trails reaching the walls.
Many Plano subdivisions have homeowner association landscaping rules, so check the guidelines before changing beds along a shared fence line. The HOA, irrigation and pests guide explains how sprinkler schedules and mulch depth affect ants, fire ants and mosquitoes.
Best when ants are in the kitchen, bath or laundry room. Baits go along the trail and near the entry point. This is the slowest method to show results and the most thorough, because the colony is reached rather than the foragers.
Best when ants keep coming back from the yard. A residual product around the foundation and treatment of nest sites in beds and turf reduces how many ants reach the walls. It is most useful alongside baits, not instead of them.
Best if ants return every spring or after every heavy rain. The exterior work is repeated on a schedule, which suits a house surrounded by irrigated beds. Ask what a general pest control plan includes before assuming ants are covered.
Many Plano homes are brick-veneer houses in homeowner-association subdivisions, typically on concrete slabs with attached garages and irrigated turf. That pattern puts moist beds, mulch and foundation plantings right against the wall, and brick veneer has weep holes near the base that small ants can use as a doorway. A technician checks those weep holes, the garage door seal and the gap around plumbing where it enters the slab.
Neighborhoods near creeks and greenbelts, such as the area around Rowlett Creek and Oak Point Park and Nature Preserve, tend to have more leaf litter, damp ground and tree cover next door. That gives colonies room to spread and then reach your wall from several directions. Homes around Legacy West and Willow Bend mix newer townhomes and apartments with landscaped common areas, where a shared bed can feed ants into several units at once.
Spring is the common start, as warm rain triggers activity, and a second push often follows when summer heat dries the beds. The Plano pest calendar lists which pests tend to show up in which months.

They do not bite in a way that matters and they do not damage wood. The concern is contamination: they walk across food and crumbs in the kitchen. They are a nuisance pest, and the goal of treatment is to end the trail, not to fear the ant.
Spray kills foragers but usually leaves the nest, which sends out new workers. Odorous house ants may also split into more colonies when disturbed. A bait-first approach, together with sealing the entry point, is more likely to stop the return.
Small black trailing ants are not termites. Winged termites and winged ants can look alike, though. If you find wings near a window, keep a few and ask a technician to look. See termite inspection if there is any doubt.
Sometimes. A small, recent trail can end after one round of baits and an exterior treatment. If ants return with each rain or heat swing, expect a follow-up check or a recurring plan. The technician explains which applies before you approve anything.
Usually yes. Baits are small and placed out of the way, and exterior treatment happens outside. The technician tells you if anything needs to dry first and where children and pets should stay out until it does.
