Cellar Spider (Daddy Long-legs)

Natural Habitat

Found globally in dark, damp environments such as basements, attics, crawl spaces, and corners of ceilings in homes.

Diet & Feeding

Carnivorous; feeds on flies, gnats, mosquitoes, and even other spiders much larger than themselves.

Behavior Patterns

Known for spinning irregular tangles of webbing; if disturbed, they vibrate rapidly in their webs to blur their outline and confuse predators (whirling).

Risks & Benefits

Non-toxic and harmless to humans as their fangs are generally unable to penetrate skin; highly beneficial as natural pest control for indoor insects.
