Many types of spiders do go through a kind of hibernation during colder months, but it isn’t exactly the same as the deep, prolonged sleep that some mammals experience.

Spiders, being cold-blooded creatures, slow down in the cold, and their metabolic rate decreases. This state, often referred to as “overwintering,” involves a period of reduced activity rather than a deep sleep. During this time, some spiders seek out shelter in places like leaf piles, under rocks, or even inside homes. Some species of spiders even produce a type of “antifreeze” in their body to help them survive in freezing temperatures.

However, not all spiders follow this pattern. Some species remain active all year, while others lay eggs in the fall that hatch in the spring, with the adult spiders dying off in the winter. The exact behavior can vary quite a bit depending on the specific type of spider and its environment.
