Cellar Spider (Pholcus phalangioides)

Appearance & Features:

Cellar Spiders are also known as 'Daddy Long Legs' due to their extremely long legs and small body of only 6-9mm which makes them look much bigger than they actually are.  They range in colour from pale yellow to light brown and grey.


Cellar Spiders prefer dark and damp spaces in which to weave their webs which are loose and iregular in shape and are usually located in corners.  The webs can get quite extensive as they are continually added on to rather than removed by the spider which hang upside down on the underside of the webs.

Threats to humans:

There is no threat to humans from Cellar Spiders.  They do not bit and genreally tend to remain in one location.


A vacuum cleaner or brush can be used to remove cellar spider webs which then restricts their activity.  Good ventilation and using a de-humidifier in basements and crawl spaces can discourage spiders. Any exterior cracks around doors and windows shoudl be sealed up.  Yellow bulbs in exterior lighting may reduce the number of spiders and other insects as they are more attracted to bighter white light.
