Frequently Asked Questions

Q: How much does carpenter ant control cost in Markham?

Nest treatment runs $250 to $600 in Markham, with the inspection from $100 to $250. The cost depends on how many nests and how much wall or attic work is involved.

Q: Are carpenter ants the same as termites?

No. Carpenter ants nest in damp wood but do not eat it, while termites eat the wood. The two need different treatments, which is why the inspection matters.

Q: Why do carpenter ants choose my house?

Carpenter ants need moisture. A leaking roof, a damp crawl space, or wood in contact with the soil gives them the conditions to start a nest.

Q: How do you find the nest?

The inspection follows the trails and the frass to the activity, and we check the common nest sites: the attic, the crawl space, and the wall voids near water.

Q: Will they come back after treatment?

Not if the moisture problem is fixed. The treatment removes the colony, and the moisture correction keeps the conditions from returning.
