Here are tips for identifying and getting rid of woodchucks or groundhogs.
What Are Woodchucks or Groundhogs?
If every day is Groundhog Day in your garden, you’ll probably agree with those who call that gluttonous rodent their least favorite backyard creature. Even skunks get more respect. Speaking of Groundhog Day, find out the origins of that funny holiday and some folklore surrounding groundhogs and weather.
The problem is that groundhogs or woodchucks are binge eaters who can wipe out your vegetable garden in a matter of minutes. They climb, they burrow, they swim, and they eat—an adult consumes about a pound to a pound-and-a-half of vegetation daily. Between spring and fall, they double their body weight.
Do Groundhogs Hibernate?
Yes they do! Soon after they emerge from a winter’s hibernation, they mate, giving birth in mid-spring—at a time when the picking are at their slimmest. Neat rows of seedlings must look like manna from heaven to hungry woodchucks, who sometimes perch on garden fence posts as if they are looking over the salad bar.
When hibernating, woodchucks, who are never speedy, really slow down, drawing a breath only about every five minutes. Hibernation is curious behavior: Barely breathing, these mammals cool off to just a few degrees above the ambient temperature, sometimes as low as 39º to 40ºF. Their metabolic rate drops, and they sleep profoundly in their winter dens, neither eating nor drinking for four-and-a-half to five-and-a-half months, drawing all their nourishment from the body fat they accumulated during the summer. No wonder they eat so much!
