Although it might seem counterintuitive, spiders often find their way into showers and bathroom crevices. Bathrooms provide moisture and attract other small insects, making them a prime feeding ground. Spiders tend to hide in corners, behind shampoo bottles, or near drains where they can stay undisturbed.
To keep spiders out, wipe down shower walls and corners regularly, and use a bathroom-safe insect repellent if necessary. Sealing any small cracks in tiles or around pipes can also help prevent them from taking up residence in your bathroom.
