Disclaimer
A booking line
detroitdeadanimalremoval.com passes calls and job details to an independent wildlife-removal operator working the Detroit metro. No trucks, technicians, office or dispatch center in Detroit. Whoever comes out is self-employed and works under their own name.
Not the city
This is not a City of Detroit service. The city's own dead-animal collection is described on its site and is limited to dogs and cats at residential curbs and in city streets.
The operator sets terms
Price, timing, scope, and whether a job is taken. Nothing on this site quotes or books anything.
No credentials claimed
Nothing on this site states any operator's licensing, insurance, bonding, permits or certification. Ask them directly.
Walls
Finished drywall, plaster and ceilings are not opened to retrieve a small mouse or rat from an inaccessible cavity. If getting to it means opening the structure, the smell is left to run its course. No timeline is promised.
Agencies and law
Statements about DPW, MDOT and Michigan law describe what those sources said when written. Not advice on your property. Confirm with the agency.
Outcome
A search does not always find a carcass. You are told what was found. Nothing is promised about the result before someone has looked.
