Although Black Bears exist in Vermont, they are shy and seldom seen. Blackflies and mosquitos can make hiking unbearable. Blackflies breed in running water so are most abundant in early summer. They usually disappear by mid-July. Long-sleeved shirts and pants are the hiker's only defense.
Mosquitos are around most of the summer and like low wet areas.
Rabies is present in Vermont, as in other areas in the Northeast. It is thus very important to do everything to discourge animals from your campsite. Hang food, carry out food wastes and trash, refrain from feeding animals and stay away from any wild animal that is acting strangely. Leave dead animals alone. If you are bitten, wash your wound well with soap and water and seek medical help immediately.
