The answer to 'how did spider get in my house' is that spiders can enter your home through a variety of ways, such as cracks, gaps, and open windows or doors. Spiders are common indoor pests that often seek shelter, food, and warmth inside homes. They may come in through small openings in the foundation, walls, or around windows and doors.
Some common causes of spiders getting into homes include gaps or cracks in the home's exterior, open windows or doors, and clutter or storage areas that provide hiding spots. Symptoms of a spider problem may include seeing spiders crawling around, finding spider webs, or noticing egg sacs. To prevent spiders from entering, seal up any cracks or openings, install tight-fitting screens, and keep the home clean and clutter-free. If the problem persists, it's best to call a professional pest control technician who can properly identify the spider species and apply targeted treatments.
