Do marmots harm people or property?
Marmots can cause major damage to gardens and crops. When feeding, marmots tend to chew the entire plant down to the ground, leaving nothing. Ripe vegetables, herbs, and cereal grains are the most enticing temptations to hungry marmots, who will dig beneath most fences to get at desired plants.
Additionally, unchecked burrows may undermine the structural integrity of manmade dams, levees, or embankments. Marmots can also carry ticks, which transmit Rocky Mountain spotted fever and other diseases to humans.
