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!

They’re reporting garbage strewn across the lawn, noise at all hours of the night, and even uninvited visitors making themselves at home in the attic! Yes, we’re talking about those neighbors: the animals that live in our neighborhoods.
