Ant Control, Including Carpenter Ants
Which ant it is changes everything. Carpenter ants excavate structural timber; pavement ants are a nuisance. The same spray does not deal with both.
Frass means the galleries are already inside the wood
Carpenter ants do not eat timber, they excavate it to nest. Coarse sawdust-like frass on a sill means active galleries inside the member, not ants passing over it.

Ant Control
Which ant it is changes everything. Carpenter ants excavate structural timber; pavement ants are a nuisance. The same spray does not deal with both.
The first question is always the species. Carpenter ants nest inside wood, preferring timber that has been damp at some point, and over time they hollow out galleries that weaken it. Pavement ants nest outdoors under slabs and paths and come inside to forage. Odorous house ants do much the same and are often mistaken for something worse. The damage potential, and therefore the treatment, is completely different.
A visible trail is useful information rather than the problem itself. Ants follow chemical trails to a resource, so the line of ants across a worktop is a route to something, and following it back is how the nest gets located. Spraying the trail removes the visible ants and leaves the nest producing more, which is why the same trail reappears in the same place days later.
For carpenter ants the inspection also looks for the moisture that made the timber attractive in the first place: a leaking gutter line, a failed flashing, a deck ledger board, a window sill that has been wet for years. Treating the ants without addressing that tends to buy a season rather than a solution.
Who it is for
Anyone seeing a persistent trail indoors, or large black ants around window frames and roof lines..
What you get
- Species identified before treatment, because carpenter ants and pavement ants need different work
- Trails followed back toward the nest rather than sprayed where they are seen
- Moisture sources checked where carpenter ants are involved
- Exterior treated as well as interior, since most nests are outside the wall

Questions, answered
How do I know if they are carpenter ants?
Carpenter ants are large, usually black, and often seen individually rather than in dense trails. The clearer sign is coarse shavings that look like sawdust below a small opening in timber or trim, sometimes mixed with insect fragments. If you are finding that, it is worth an inspection because they nest in wood rather than just walking across it.
Why do the ants come back to the same spot?
Because the nest was never the thing that was treated. Ants follow a chemical trail to a food or moisture source, so removing the visible ants leaves both the trail and the colony intact. Treatment that works targets the colony, which means locating it first.
Are ants a sign of a damp problem?
They can be, particularly carpenter ants, which favour timber that has been wet. Finding them around a window frame, a roof edge or a deck ledger is often the first sign of a leak that has been going on quietly. The inspection covers that as well as the ants.
