The key for controlling the domestic house spider is to look for webs and remove them, making sure a treatment
is applied into any crack associated with a web to be sure the spider has been killed.
Steps that should be taken to prevent new spiders from entering include:
Removing or limiting heavy, ground-covering vegetation near the building.
Sealing cracks and holes in the building s exterior.
Installing tight-fitting screens on all attic and foundation vents.
Sealing holes around pipes indoors to prevent spiders from entering the living spaces of the home by following
plumbing lines in basements and crawl spaces.
Where numerous spiders are seen, a professional should be consulted to conduct a thorough inspection and
recommend possible treatments.
