The answer to 'what attracts spider' is that spiders are attracted to areas with an abundance of insects, their primary food source. Spiders are also drawn to dark, quiet, and undisturbed spaces like corners, cracks, and crevices where they can build their webs and hide. Moisture and clutter can also make a home more appealing to spiders.
Spiders are generally not a major health concern, but their presence can be unsettling for many homeowners. While you can try DIY methods like sealing entry points, removing clutter, and using natural repellents, it's best to call a professional pest control technician if you have a significant spider problem or are dealing with venomous species.
