Brown house spiders are very common in man-made structures and are also found outdoors in sheltered places including in tree bark, wood piles, under rocks, on low-growing foliage and in outdoor storage buildings. When found indoors, they usually build their webs near the ground-level floors, but also may build inside cupboards and cabinets and can be found more or less throughout the year.
Brown house spiders mate in the spring with females producing 2 or 3 egg cases every few months. Each sac contains 10-250 eggs. After hatching, spider lings go through two molts and then leave the egg sac.
Signs of an infestation:
The presence of the spiders, their egg sacs, webs and the appearance of dead prey are evidence of brown house spiders living inside the home.
Prevention & Control:
Sealing all cracks, gaps and crevices that provide access inside the home is an important way to prevent spiders from wandering into the structure. Another preventive method is to use a vacuum or broom to remove spiders, webs and egg cases. Finally, make sure the insects that serve as the brown house spider’s food source are kept to a minimum and harborage sites are removed and cleaned up.
