Cellar spiders (Pholcidae) are common household spiders known for their extremely long, thin legs and small, round bodies. They're often called "daddy longlegs" due to their distinctive appearance. Cellar spiders have pale yellow to light brown bodies that are typically 1/4 inch in length, with legs that can span up to 2 inches. They build messy, irregular webs and are known for their characteristic behavior of hanging upside down when disturbed.
Cellar spiders are not dangerous to humans. They don't have venom strong enough to harm people and are generally non-aggressive. However, cellar spiders can become a nuisance when they build large numbers of webs in homes. Their webs can become unsightly and may trap other insects, creating additional pest problems. While they're beneficial in controlling other insect populations, their presence in large numbers can be undesirable.
Cellar spiders are attracted to dark, undisturbed areas and may enter homes seeking shelter or food. They commonly infest basements, attics, closets, and other areas that are rarely disturbed. Cellar spiders may also be drawn to areas with other insect populations, as they feed on insects and other small arthropods. They may enter homes through cracks, gaps, and other small openings.
Cellar spiders prefer dark, secluded areas and are commonly found in basements, attics, closets, storage areas, and crawl spaces. They may hide in boxes, clothing, shoes, and other items that are rarely moved. Cellar spiders are nocturnal and are most active at night. They build irregular webs in dark corners and may be found hiding in dark, undisturbed areas.
