Throughout Michigan's Lower Peninsula, baiting is prohibited on private property and public land alike. The Upper Peninsula permits it under tight restrictions. The Michigan DNR attributes that boundary to bovine tuberculosis along with chronic wasting disease in the Lower Peninsula. Lawmakers are challenging the prohibition: the state House approved legislation in February 2026 that would remove it, and Senate action remains pending. Bait brings deer together, spreading both diseases that Michigan is already battling (Working Paper 11). Disease locations guide the rules.
KEY FINDINGS
- On private property and public land alike, baiting is prohibited throughout the Lower Peninsula. A limited exception covers eligible hunters with disabilities taking part in Liberty and Independence hunts.
- Hunters in the Upper Peninsula may bait under restrictions. Each site is capped at 2 gallons, distributed across an area measuring at least 10-foot by 10-foot. The permitted period begins Sept. 15 and ends Jan. 1.
- Disease locations explain the boundary. The Lower Peninsula contains the core area of endemic TB as well as CWD detections. The Upper Peninsula has a restricted baiting allowance, and the DNR has imposed no baiting ban there.
IThe split
Two peninsulas follow two sets of rules
Michigan sharply separates its peninsulas when regulating deer bait. Throughout the Lower Peninsula, baiting is prohibited, apart from a limited exception for hunters with disabilities participating in Liberty and Independence hunts. In the Upper Peninsula, restrictions apply, but baiting is legal. A hunter traveling over the Mackinac Bridge reaches a different set of baiting rules. Disease locations are the explanation given by the Michigan DNR.
IIWhy bait and disease collide
Crowded deer face greater transmission risk
Close contact spreads both diseases Michigan is fighting. Deer pass bovine TB to one another through shared feed and saliva. CWD is caused by infectious proteins called prions, which collect in places where infected deer gather and release them. A bait pile is designed to bring many deer nose to nose in one location, day after day. That repeated crowding makes it an ideal engine for spreading these particular pathogens. This reasoning reaches beyond Michigan. Feeding historically sustained Michigan's TB core, and that core was the first basis for the case against baiting.
By gathering deer together, bait piles raise the risk of disease spreading. That risk helps shape Michigan's restrictions on baiting.
IIIThe Lower ban and the UP allowance
Shared reasoning, differing risks
Michigan's counties with endemic bovine TB lie in the Lower Peninsula, which also contains the state's CWD detections. Those disease locations explain the DNR's baiting prohibition there. The DNR has imposed no baiting ban in the Upper Peninsula. Its allowance caps each site at two gallons, distributed across an area measuring at least 10-foot by 10-foot. Baiting may begin Sept. 15 and must end Jan. 1.
IVWhat it means
An example of rules shaped by disease
Michigan's division over baiting deserves examination outside the state. It offers an honest example of regulation based on disease: differing risks bring differing rules. The state illustrates one way a rule can track disease risk, while lawmakers challenge its Lower Peninsula prohibition. Michigan has tested this approach for years; the division between peninsulas is its clearest outcome. Working Paper 11 links deer gathering together with disease risk. Hunters should look up the baiting requirements that apply in their hunting peninsula.
NOTES AND SOURCES
- Michigan rules for feeding and baiting: baiting is prohibited throughout the Lower Peninsula on private property and public land alike, with an exception covering disabled hunters participating in Liberty and Independence hunts. The Upper Peninsula permits baiting, capped at 2 gallons at each site and distributed across an area measuring at least 10-foot by 10-foot. The permitted period begins Sept. 15 and ends Jan. 1.

- The Michigan DNR identifies disease as the basis for its baiting restrictions: bait gathers deer together and speeds transmission of CWD and TB. Working Paper 11 describes where those diseases occur.
