The answer to 'spider health risk' is that most spiders found in homes are not a significant health risk to humans. Common house spiders are generally not aggressive and their venom is not potent enough to cause serious harm. However, some spider species can be dangerous and should be handled with caution.
The main health risks from spiders are potential bites, which may cause mild reactions like redness, swelling, and itching. In rare cases, some people may have a severe allergic reaction. It's important to avoid startling or provoking spiders, and seek medical attention if bitten by an unfamiliar spider or experiencing concerning symptoms.
