Black Footed Spiders
(alternately known as the yellow sac spider or black-footed spider)
The black-footed spider has a body length of between 4mm and 9mm (1/6" and 1/3"), though its leg span can reach up to 30mm (1")
across. It is a pale yellow-beige in colour, with dark markings on its palps, jaws, and feet. The black-footed spider
builds small silk nests in which it lairs and lays its eggs, but does not use a web to catch prey. Instead it is an active
hunter. Black-footed spiders are nocturnal, and typically retreat to their nests during the day. Their bites can be
painful, but they are not believed to be toxic to humans.
Control of the black-footed spider is a six step process: inspection, identification, prevention, sanitation, use of mechanical
measures (vacuuming), and treatment. In most cases, treatment is exterior, applied to the fascia, soffits, windows, door
frames, and exterior walls. However, in the case of extreme infestations, an interior treatment may be necessary. If you
are having problems with black footed spiders, York Pest Control will assess your situation and help you get rid of them.
