Troy particulars
Troy's Code Enforcement office publishes a Pest Prevention page covering rats, mice and feral animals. It says not to feed them, to seal openings and to remove woodpiles and brush, and it argues against rodenticides because of secondary poisoning. That is the city's position, not state law. The city also has a Wildlife page, a Multiple Family Rental Inspection Program and a rule that food waste goes in rodent-proof containers.
The Oakland County Health Division serves Troy, and its site has moved to oaklandcountymi.gov. Per the county, West Nile risk peaks from late July through September. As of October 2, 2026, it counted no positive mosquito pools, three animal cases and six human cases in Oakland County, and it describes a reimbursement program for participating local units that the page does not fully explain. We cannot point you to a Troy city spraying program, so ask the city.
The county's tick page says ticks are found in nearly every Michigan county. Troy counts 87,307 residents, a median home value of $396,800 and 60.5 percent of homes dating from before 1980 (Census ACS 2023). Licensing of applicators sits with MDARD and not the city. The closest places are Clawson, 3.3 miles, Birmingham, Royal Oak, Rochester Hills and Madison Heights.
Rodents in Troy: what to know
Troy's Code Enforcement office publishes a Pest Prevention page for rats, mice and feral animals: do not feed them, seal openings, remove woodpiles and brush, and keep food waste in rodent-proof containers. It argues against rodenticides because of secondary poisoning. That is the city's position, not state law, and a licensed company may lawfully use registered products under their labels.
Troy's 87,307 residents live in a housing stock that is 60.5 percent pre-1980, with a median home value of $396,800 (Census ACS 2023). If a company proposes bait, ask where it will go, how it will be secured and when it will be checked, and what it will do about the entry points, which the page and the EPA both stress.
Permits for rodents in Troy
MDARD's category 7D covers using pesticides against vertebrate pests such as birds, rats and mice, and 7A covers pests in and around dwellings.
Many cities run their own building department, so start by asking the City of Troy building department who issues pest control permits.
Rodents: urgent or not
- Droppings or chewed packaging in a space where you prepare or store food: clean up, seal the food, and book the same week.
- A single mouse sighting with no droppings in food areas.
- Noises in a wall or ceiling that stop in daylight.
What to try before you call
Try this first: read the city's Pest Prevention page, then ask how the company's plan fits it.
- Put food in sealed containers and clean up spills and standing water.
- Find holes by looking along the walls and floors for droppings and chewing.
- Seal what you can reach with steel wool or a patch.
- Note where you see the signs and photograph them.
- Ask the company to show you every entry point it found.
What rodents cost
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Troy in particular. The same table is on the rodents page. How we estimate costs. Prices as of Oct 19, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $125 to $680 per job | Built from one national published range, adjusted by the Michigan pest control worker median wage ratio (0.98). No Michigan pest control company price is shown, because none of the companies we looked at published a regular price. |
| Pest control worker wage, Michigan median | $21.38 an hour | What pest control workers are paid (O*NET republishing BLS, May 2025), not what you are charged. Percentile data, not re-checked against the BLS table. |
| State fee, certified commercial applicator | $75 | Paid by the person, not added to your bill as a line. Michigan statute and MDARD agree. |
| State fee, pesticide application business license | $100 a year, expires every December 31 | Every company that applies pesticides for hire needs one, in addition to its applicators' credentials. |
How we estimate costs: the Estimated range row is a model, not a quote. It takes one published national range for this job (a cost guide from a third-party site that we have not verified and do not cite) and multiplies it by Michigan's pest control worker median wage ratio to the US (0.98, BLS May 2025 data read through O*NET OnLine). The wage and state fee rows in the table are what pest control workers are paid and what the state charges to license them, and neither is a price. We have not collected quotes, and we found no Michigan pest control company that publishes a regular price. Full method.
Questions about rodents
How do I keep rodents away in Michigan?
Remove food, water and shelter, and seal the holes, using steel wool or a patch, according to the EPA. DNR suggests metal flashing or hardware cloth and a capped, screened chimney for small wild rodents, with the caveat that its page covers wild species.
What qualifies as a rodent infestation?
The EPA does not set a count; it lists signs: droppings near food, nesting material, and chewed holes in walls and floors. If you see those, act on the entry points and ask a company to inspect.
Is it worth getting an exterminator for mice?
It is when you cannot find or reach the entry points, or when you want bait handled by a licensed applicator. Sealing is the part that lasts, so ask the company what it will do about the holes.
