Deer, mice, raccoons and squirrels are adept at gnawing through packs in search of food. Porcupines gnaw on shelters, outhouses, boots and anything with salt on it. Doors need to be latched and boots hung to deter these determined creatures. 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.
