Yellow Sac Spider

Commonly found indoors on walls and ceilings, or outdoors in gardens, timber, and foliage

Strictly carnivorous; feeds on small insects such as flies, moths, and other spiders

Nocturnal hunters that do not build webs to catch prey; instead, they build small silk 'sacs' or tubes for resting during the day

Benefits the ecosystem by controlling pest insects. Their bite can be painful (similar to a bee sting) and may cause swelling or localized redness, though they are generally not considered medically significant to healthy humans
