The answer to 'why is my spider damage' is that you likely have an infestation of spiders in your home. Spiders can cause damage by building webs, leaving behind egg sacs, and even biting humans or pets. Common signs of spider damage include cobwebs, egg sacs, and holes or discoloration in fabrics or wood. To address spider damage, you'll need to identify and eliminate the source of the infestation, which may require the help of a professional pest control technician.
Spiders are attracted to dark, undisturbed areas of the home, such as attics, basements, and behind furniture. They build webs to catch prey, and their egg sacs can hatch hundreds of baby spiders. If the infestation is widespread or you have concerns about dangerous spider species, it's best to call in a professional pest control expert who can properly identify the spiders and use the appropriate treatment methods to get rid of them.
