Q. Can earthworms survive freezing?
A. If frozen, they will die. Earthworms fall into the category of freeze-avoiding invertebrates. Some adults survive freezing temperatures by going below the frost line in winter to "sleep." Earthworm cocoons, however, are much more tolerant to freezing and worm eggs within a cocoon survive deep in the soil over winter to hatch in the spring when conditions are right.
Q. What do earthworms do when it gets too cold, too hot, or too dry?
Q. What do earthworms do when it gets too cold, too hot, or too dry?
A. Earthworms escape by either burrowing deeply into the soil (up to about 6 feet or 2 meters), or entering a reduced metabolic state known as estivation. Estivation is a form of hibernation that takes place when temperatures get too hot or too dry for earthworms. When conditions are favorable, the worms will emerge and resume normal activities.
