The answer to 'why is my spider damage' is that spider damage is typically caused by the webs, nests, and egg sacs that spiders build around your home. Common symptoms include seeing spider webs, egg sacs, or actual spiders, as well as finding small holes or damage to surfaces where they've built their nests. The best solutions depend on the extent of the damage, but typically involve removing the webs and nests, sealing any entry points, and using targeted pest control treatments if necessary.
For minor spider issues, you may be able to handle the problem yourself with DIY pest control methods. However, for more extensive spider infestations or damage, it's best to call in a professional pest control technician who can properly identify the spider species and recommend the most effective treatment plan.
