Spiders are cold-blooded creatures, so where do they wriggle off to when the snow flies? Read on to find out, and to see whether this year’s harsh weather means you’ll be seeing fewer arachnids in your neighborhood.
The Short Answer: It All Depends on the Species
The U.S. and Canada are host to at least 4,000 known species of spider, and each one has its own strategy for surviving the cold season. There are 3 basic strategies that common North American spiders use, and they are:
Option One: Stay Outside
Many spiders adapt to staying outside throughout the winter, even in the coldest areas. Some species, such as the orbweaver Araneus saevus, spend the winter in egg form and hatch during warmer weather.
Others, such as the male hackledmesh weaver (Amaurobius and Callobius sp.), overwinter as immature spiders. Still others, such as the female hackledmesh weaver, overwinter as adults.
Hackledmesh weavers seek shelter in damp, dark areas such as leaf litter… or your basement.
Option Two: Come Inside
Some spiders have learned to lean on us humans for shelter during the colder months. The hackledmesh weaver, above, will look for shelter outdoors sometimes, and sneak indoors other times.
Females commonly nest in basements, especially in the fall. The parson spider (Herpyllus ecclesiasticus) seeks out structures such as barns, garages or homes to hibernate for the winter.
Adult female wolf spiders (Hogna aspersa) seek shelter to make their winter homes, and they’re known to sneak into homes and garages to stay warm.
Option Three: Stay Inside
Some spider species have adapted to living alongside us humans for so long, they never really leave our sides. Spiders such as the common house spider spend their entire life cycle in or around human-built structures, and reproduce year-round.
“Not MY House, Mr. Spider!”
Some spiders sneak into your warm home during the cold weather, while others that spend winter as eggs or immature spiders may wander inside when the temperature rises and they’re on the prowl for a mate.

So… Does the Tough Winter Mean Fewer Spiders this Year?
For most of us, probably not. Spider species that live in places like the Northeast and Midwest have adapted to pretty harsh temperatures, and the extra dose of snow cover that a lot of us got this year actually serves as added insulation for spider eggs.
The only folks who at least have a chance of a slightly reduced bug population this year are those who live in areas in the South that got hit with sub-freezing temperatures where they don’t usually occur.
Some species in those areas may not have been as well prepared for the conditions, and may lose some of their numbers. For more information on the different species of spiders that may be in your home check out our article here.
