if it is a problem animal you can kill when ever needed that comes from the dnr and for snares I called the DNR and as long as it is on private land it is game on. this is from the trapping regs in regards to snares in the lower part of the state
General Restrictions for Snares
• Bears cannot
be taken
with snares.
• In the farmland Furbearer Zone no person may set, place, or operate
any snare except as a waterset, other than from Dec. 1 to March 31
when snares are allowed on land except on public lands, road rightsof-
way or in fence lines along road rights of way. A waterset is any
snare set so that the snare loop is at least half submerged.

wholly or partly lift from the ground an animal
caught in the snare.
• No snare may be set in such a way that the top of the loop is
more than 16 inches above the ground or, when the ground is
snow-covered, more than 16 inches above the bottom of a person’s
footprint made in the snow beneath the snare with the full
body weight on the foot.
• All snares not capable of drowning the captured animal must be
tended at least once each calendar day.

the applicable trapping season has closed.
if you call the DNR hotline they will tell you that as long as they are killing live stock you can shoot them trap them kill them but you cannot transport them alive.
As for the dens they live on a tree huggers farm and she is feeding them she told me I could go and look at the dens in a brush pile but no shooting or traping just looking.
