Do House Spiders Bite?

Many homeowners ask whether house spiders are likely to bite. Do house spiders bite? The answer is that most common house spiders are uninterested in biting humans. Spiders only bite humans during life-threatening defence measures or when they feel attacked, although their jaw muscles probably cannot puncture human flesh. An actual spider bite usually produces no more than temporary redness, swelling, and mild irritation resembling a mosquito bite response.

Severe reactions rarely affect the black widow and brown recluse spiders, though these two types are not usually found in homes. Typically, skin irritations that people suspect as spider bites actually stem from either insects or unrelated skin issues. The Wolf Spider, giant house spider, wood spider, jumping spider, flying spider, and other common house spiders are likelier to run and hide than to bite.

Conclusion

Although ordinary house spiders, such as the Wolf spider, jumping spiders, giant house spider, wood spider, and the flying spider may look terrifying, most are not harmful and are the best fighters in the anti-revolting war against household pests. Case reports of people being bitten by these spiders are rare and usually not serious.
