Treatment Options

Inspection and Species Identification

Typical published range: $75–$200

A pro in Ann Arbor starts by tracing trails to entry points and the likely nest, then identifies the species. The wrong bait for the species simply gets ignored.

45–90 minutesBest: Every job; the species decides the method

Sealing Gaps, Cleanup and Follow-Up

Typical published range: $100–$300 per visit

A follow-up visit two to four weeks later confirms trails have stopped in Ann Arbor kitchens and bathrooms and re-baits if needed. Most plans include at least one return trip.

30–60 minutesBest: Sealing gaps and confirming the colony is gone

Gel and Granular Baiting for the Colony

Typical published range: $150–$400

Gel placements go where ants travel, not where people see them, so an Ann Arbor pro will bait behind appliances, under sinks and along foundation seams. Placements are small and kept out of reach.

45–90 minutesBest: Odorous house, pavement, Argentine and Pharaoh ants

Carpenter Ant Nest Treatment

Typical published range: $250–$600

Where a nest sits in an Ann Arbor roofline, deck or damp sill, treatment may pair with a recommendation to replace rotten wood. That repair is usually a separate contractor's job.
