Wyoming particulars
Ten of the places on this site are in Kent County, and Wyoming is the second largest. The county health department does mosquito and tick surveillance from April through September, a description we have only at second hand, so confirm it with the county. MDHHS counts four human West Nile cases and 22 positive mosquito pools there as of October 16, 2026. Wyoming's median home value is $203,900 and 65.1 percent of its homes were built before 1980, among 76,865 residents (Census ACS 2023).
MDHHS says blacklegged ticks, the ones that carry Lyme disease, are established in the western Lower Peninsula and active whenever outdoor temperatures are above 40 degrees Fahrenheit. That is a reason to check yourself and your pets after yard work in March as much as in July. The timing advice is ours, and the temperature rule is MDHHS's. For a bat in the house, DNR calls any contact where a bite cannot be ruled out a potential rabies exposure to report to the local health department. Nearby are Grandville, 2.4 miles away, Cutlerville, Grand Rapids, Kentwood and Jenison. MDARD licenses applicators here, and the city does not.
Rodents in Wyoming: what to know
Wyoming's own profile is 76,865 residents, 65.1 percent of homes built before 1980 and a median home value of $203,900 (Census ACS 2023), and its site offered no rodent page we could cite. Grand Rapids, 5.5 miles away, says in its Neighborhood Living Guide that property owners are responsible for preventing conditions that provide a home or food source for rats, which is a useful statement of principle even though it is not Wyoming's rule.
Before hiring, ask which category the applicator holds, since MDARD does not say in one sentence if a mouse job needs 7D or 7A. At each application, get the product label, the target pest and the active ingredients.
Permits for rodents in Wyoming
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 Wyoming 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: remove food and water sources outdoors, such as pet food and standing water, before the visit.
- 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 Wyoming 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.
