No One Likes Spiders

Fact.

If you ever see one of these arachnid abominations, it's your civil duty to see to its demise. They're by far the most hated animals on the planet, and it's easy to see why. They have eight terrible legs, four pairs of revolting eyes, big intimidating backs, and feel wrong when they crawl on your skin. In short, spiders are all-around unpleasant creatures who are miserable and must be annihilated at all costs.

Spiders have the proper representation in fiction: terrible creatures whose existences are unwelcome wherever they go. If someone moves an old log in their yard and find an absolute army of spiders hanging out under it, what do you think the first thing they'll do is? It certainly wouldn't be say, "Aww, look at all the cute spiders!" because no one in their right mind would dare say, or even think, that. They'd yell, run off to grab their friendly neighborhood flamethrower, and roast those fuckers alive. That is, of course, if they don't bomb the hell spawns instead. Either way, both completely rational and understandable choices.
