The answer to 'why is my spider health risk' is that most spiders found in homes are not dangerous to human health. While some spiders can deliver a painful bite, the vast majority of common house spiders in North America are not venomous enough to pose a serious health threat. However, it's still important to be cautious and avoid handling spiders, as a small percentage may have venom that can cause mild reactions in some people.
The main health risk from spiders is the potential for allergic reactions or skin irritation from their bites. Symptoms may include redness, swelling, and itching at the bite site. In rare cases, a person may have a more severe allergic response. If you experience concerning symptoms after a spider bite, it's best to seek medical attention.
