Targeted nest treatment
Best when the nest has been found, for example in a wall void or under a sill plate. Product goes into the cavity itself. This is the most direct approach and is usually paired with an exterior treatment.

Carpenter Ants
Carpenter Ant Control: what it covers
Quick answer
Carpenter ants nest in damp or decayed wood and excavate galleries without eating it. In Plano the usual clues are large black ants indoors at night, fine sawdust piles called frass and rustling in a wall. A technician traces trails to the nest, treats it and points out the moisture source. Plano Pest Control serves Collin County.
Carpenter ants are the big ones. Workers range in size and can be a half inch long or more, usually black or dark brown, and they walk with a deliberate pace rather than a hurry. Unlike termites, they do not eat wood. They chew it out to make smooth galleries, push the shavings out of a small hole and leave a neat pile beneath it.
That pile, called frass, is the best clue. It looks like coarse sawdust mixed with bits of dead insect, and it tends to show up under a window sill, at the base of a wall or under a porch beam. A single ant crossing the kitchen at night means little. A steady stream of big ants, or frass on the floor, means there is a colony close by, and usually moisture damage that made the wood soft enough to nest in.
This is different from the small trailing ants in the kitchen, which are covered under odorous house and rover ant control. Carpenter ant work is about locating a nest, which can be in a tree outside or inside a wall, and about fixing whatever is keeping the wood damp. Where termites are the worry instead, see termite inspection.

How do I tell carpenter ants from termites?
Carpenter ants have a narrow, pinched waist, elbowed antennae and, if winged, a larger front wing pair. Termites have a thick, straight waist, straight antennae and four wings of equal length. Carpenter ant galleries are smooth and clean, while termite tunnels hold mud and soil, and termites do eat the wood.
If you are unsure, catch a few in a jar or tape and show them to the technician. Treating the wrong insect wastes money, and a termite problem is more urgent than an ant problem because the damage is done by eating the wood.
A termite inspection is a reasonable step whenever you find wings or frass and cannot name the insect.
Why do carpenter ants nest in wood that is not rotten?
They prefer wood softened by moisture, but they will also tunnel through sound lumber that sits next to a damp spot. A colony often starts in a hollow limb or a rotting stump and then sends satellite groups into house framing near a leak. Moisture, not the age of the house, is the common thread.
Common spots include window frames where caulk has failed, the wood under a leaking tub or dishwasher, fascia boards under a clogged gutter and roof sheathing below an old leak. Spring storms with large hail have been reported in the Plano area, and damaged shingles or flashing can let water into the roof deck, so roof repairs after a storm are a reasonable moment to ask for an attic check.
None of this means your house has a problem, only that wet wood is where to look.
Do trees near my house matter?
Yes. Mature oaks and pecans can host a parent colony in a dead limb or a hollow trunk, and branches that touch the roof work as ant highways. Trimming limbs back from the house, removing stumps and keeping firewood and landscape timbers off the ground near the wall all reduce the chance of a nest next door.
Always check homeowner association rules and ask a licensed tree service before removing a large tree. A technician can tell you whether the tree or the house is the source, which helps you decide where to spend money first.
Will the ants damage my house structurally?
Damage is usually slow and limited to the area around the nest, but it grows if the colony stays and the wood stays wet. Carpenter ants remove wood to make galleries rather than eating it, so the damage is less rapid than termite feeding. Early treatment and fixing the moisture source keep it small.
If a floor feels springy or a sill plate is soft to a screwdriver, ask a contractor to assess the framing. A pest technician identifies the insect and treats; a contractor repairs the wood.
Warning signs
Signs you need carpenter ant control
Do not tear open a wall or ceiling hunting for the nest, and do not spray a foaming insecticide into cavities near wiring. Probing damaged wood gently with a screwdriver is fine, but leave nest treatment, and any repair of damaged framing, to qualified people.
- Large black or dark brown ants walking indoors at night, especially near the kitchen or a bathroom
- Small piles of coarse sawdust, often mixed with insect parts, under a wall, sill or beam
- A faint rustling or crackling sound inside a wall or ceiling on a quiet evening
- Winged ants inside the house in spring, rather than outside near a light
- Ant trails running along a fence, a power line or a branch that touches the roof
- Soft or blistered wood around a window frame, a deck post or a leaking pipe
- Smooth, clean-edged tunnels in wood when you probe a damaged area with a screwdriver
- Large ants in the attic, particularly near the roof sheathing after a leak
Our process
How our carpenter ant control visit works
Look for frass and trails
The technician inspects inside and out, checking window frames, door casings, attic edges and the crawl of ants along trees, fences and utility lines. Frass piles and the time of day the ants appear point toward the nest.
Locate the parent nest and satellites
Parent colonies are often outdoors, in a tree stump, a hollow limb or landscape timbers. Satellite colonies, with workers and brood, can sit in damp wood inside the house. Both need treating or the problem returns.
Find the moisture
A leaking roof, a dripping pipe, a clogged gutter or a poorly sealed window usually made the wood soft. The technician points to it so a roofer, plumber or handyman can fix it, because this work is outside pest control.
Treat the nest and the trails
Baits and labeled dust or foam products go into the nest area where it can be reached. Exterior treatment at the foundation and around trees reduces how many ants approach the house.
Follow up
Carpenter ant activity should drop in the days and weeks after treatment. A written report records what was found, what was applied and what repair is still needed. If activity continues, a technician checks for a second nest.
Options
Types and options for carpenter ant control
Bait and perimeter treatment
Best when the nest cannot be reached, such as a limb high in a tree or a hollow behind a masonry wall. Workers carry bait back to the colony, and an exterior barrier cuts down the foragers reaching the house.
Inspection with a repair referral
Best when damage is suspected but no ants are active. The technician looks for moisture, decay and entry points and tells you whether pest treatment is needed or a repair comes first.
Job stories
Typical jobs for carpenter ant control
Typical call: carpenter ants near a mature oak in Richardson
- What homeowners notice
- In an older brick ranch with a large oak near the roofline, the homeowner sees large black ants in the kitchen at night and a little fine sawdust under a window frame. A damp spot where a gutter overflows has been there for some time.
- What we do
- The technician follows the ant trail to likely nesting spots, checks the damp wood near the gutter, the window frame and the attic edge, and applies a treatment to the nesting areas according to the label. Trimming limbs that touch the roof and fixing the moisture source are explained.
- What to expect
- Ant sightings typically drop after the nest is treated and the moisture is dealt with, and the written report lists what was found and what the homeowner should fix.
Cost
How much does carpenter ant control cost in Plano?
Carpenter ant pricing depends mostly on how hard the nest is to find and reach. A short list of what shapes it:
| Job | Typical range | What it includes |
|---|---|---|
| Whether the nest is outdoors or inside the structure | Explained after inspection | a nest in a wall void takes more time than a treatable stump |
| Number of colonies and trails | Quoted per visit or per plan | satellite colonies mean more spots to treat and another visit to check |
| Home size and tree cover around it | Set on site | more trees and fence lines means more places to inspect and treat |
| Repairs to wet or damaged wood | Not part of pest work | a contractor quotes carpentry or roof repair separately |
The technician explains the price and the plan after the inspection, and nothing is applied until you approve it.
One call and it gets handled.
Most carpenter ant control calls are scheduled the same day when a technician is free, and you approve the price before any work starts.
Collin County
Why carpenter ant control is different in North Texas
The older neighborhoods in central Plano and nearby Richardson, with 1960s and 1970s brick ranches and large mature oaks and pecans, are where carpenter ants are most worth watching for. Big trees give a parent colony a place to settle, and older roofs, windows and fascia boards have had more years to take on water. Homes in newer subdivisions have younger trees, but landscape timbers and fence posts can serve the same purpose.
North Texas weather does the rest. The Blackland Prairie clay across much of the area swells and shrinks with moisture, and sprinklers run through the summer, so soil and mulch beside a wall can stay damp even in a dry August. Wet wood on the outside of a house is an easy place to start. The HOA, irrigation and pests guide looks at how sprinkler settings affect this.
Spring is when winged carpenter ants are most likely to be noticed. If you see them inside, rather than outside by a porch light, they are probably coming from a nest in the house. Call for an inspection rather than waiting to see whether it happens again.

FAQ
Carpenter Ant Control FAQs
Do carpenter ants eat wood like termites?
No. They tunnel through wood to make nest galleries and push the shavings out, but they feed on sugary foods, honeydew and other insects. The damage looks like clean, smooth tunnels. Termites eat the wood and leave mud-lined galleries.
Is seeing one big ant a sign of an infestation?
Not necessarily. A single foraging worker can wander in from a tree or fence. Several big ants a night, frass piles, or winged ants inside the house suggest a nearby colony and are worth an inspection.
Can I just spray the ants I see?
Spraying visible workers does not reach the nest, where the queen and most of the colony live. It can also scatter foragers and make the nest harder to find. Baits and targeted nest treatment are the more reliable route.
Does a new roof or a repaired leak end the problem?
It removes what attracts the colony, which helps. But an established nest does not leave on its own, so treatment is still needed. Fixing the moisture is the long-term step that keeps a new colony from settling.
Will you repair the wood they damaged?
Pest control treats and identifies. Replacing damaged framing, trim or sheathing is carpentry, which a licensed contractor of your choice handles. The technician's written report can help you describe what was found.
Do I need a termite inspection too?
If you cannot tell which insect is in the wood, yes. Carpenter ant frass looks like sawdust and termite damage looks like soil-lined tunnels. A technician can tell them apart quickly. See termite inspection for what is checked.
