How to Identify

Cellar spiders are easily recognized by their extremely long, thin legs and small, cylindrical body. They are pale yellow to light brown in color and have eight eyes arranged in two groups of three with two smaller eyes in between. Their delicate appearance belies their hunting prowess.

Signs of Infestation

Look for loose, irregular webs in dark, undisturbed areas such as basements, crawl spaces, and garages. These webs are often messy and tangled, and may contain trapped insects. You might also see the spiders themselves hanging upside down in their webs.

Health Risks

Cellar spiders are not considered dangerous to humans. They are not aggressive and their fangs are too small to easily penetrate human skin. They may be considered a nuisance pest due to their webs, which can accumulate dust and debris, particularly in humid Myrtle Beach homes.

Habitat

Cellar spiders thrive in dark, damp environments, making Myrtle Beach homes ideal habitats. They are commonly found in basements, crawl spaces, garages, and sheds. The humid subtropical climate of coastal SC provides ample moisture for these spiders to survive and reproduce.
