A female Black House Spider wraps her eggs in a flat white silk egg sac. She hides the sac in her web or near a nearby crevice. The mother guards the sac until the spiderlings hatch. Each spiderling produces milk thread's, which are caught by the wind and carry the young spiders away. The venom of the Black House Spider is poisonous but not lethal, it can cause much harm to humans.
