Unlike mosquitoes, which feed on humans and seek them out, spiders have no interest in biting you, and will only do so if they are being crushed or otherwise threatened. Small spiders are unable to break the skin, but even the bites of larger spiders are largely harmless. In fact, most ’spider bites’ turn out to be something other than a bite - such as a serious bacterial infection or even skin cancer!

Yes, we’re talking about those neighbors: the animals that live in our neighborhoods.
