The answer to 'spider season' is that spider activity and populations typically peak in the fall months, from September through November. This is known as 'spider season' because that's when spiders are most active and visible around homes and buildings.
Spiders are seeking mates and looking for warm, sheltered places to build nests and lay eggs before winter. This increased activity leads to more spider sightings indoors and outdoors. While it may seem like there are more spiders, this is a natural seasonal pattern and not a sign of an infestation. Taking some simple steps can help reduce spider encounters during this time.
