Rain or shine, hot or cold, it’s possible you can encounter spiders in your home year round. It may feel like spider season every season, but that’s not exactly the case. Different spider varieties can survive and thrive differently throughout different weather conditions! Here is a guide to spider activity throughout the seasons.


Although temperatures are dropping, some spiders aren’t going into hibernation. Instead of seeking warmth, some spiders can produce a glycol compound that acts similarly to antifreeze in cars! 

Spider eggs cannot survive the freezing temperatures in winter, so, when spiders lay eggs in the fall, they choose to nest in well insulated, warm places. Spiders will also add an extra thick layer of webbing to insulate an egg sac… but the best way to keep spider eggs warm is to lay them inside your warm home. In cold months, check basements, attic corners, behind pipes, and under sinks for spider eggs.


Spiders that may have hidden during the winter will emerge in the warmth of spring. Female spiders of many species will lay eggs during the first few months of warmer weather. Spiders can lay anywhere between 100 and 2,500 eggs.

In the spring, make sure to inspect your home for any possible entry points for spiders. Check for cracks and gaps in the foundation, holes in screens, space between your doorframe and door, etc.


Critters of all sorts are active in summertime. Spiders are likely to enjoy the comforts of your home in summer in search of food. Spiders feed on other insects like flies, mosquitoes, and even other spiders. To prevent spiders in your home, practice routine pest control. While different spiders are active all year, it’s more likely that you will see them moving and hunting during warmer months.


Springtime eggs are adult spiders by the fall, so they seem to be everywhere by this time of year and are often larger. Fall is also mating season, so spiders will be out and about in search of a mate. Spiders are also looking for a warm shelter for winter during the fall, and the spiders who didn’t lay eggs in the spring will look for a cozy place to lay their eggs around this time, too.

Spiders are possible home invaders during any season, so it’s important to keep diligent with your pest control and maintain a routine with inspections. They can also live for up to 25 years, depending on the species, so a spider problem can stick around for years to come.
