Let's be honest, if you've never straight-up teleported over your furniture in a desperate attempt to get away from a cockroach then you're either the bravest human who has ever lived or you're a goddamn liar.
The general repulsion of cockroaches is shared among millions of people, and it's not for naught. Roaches are usually associated with uncleanliness, and whether or not that's entirely true, you know that you'll find these disease-carrying hellbeasts eating garbage and fucking up your day by scuttling out from under your bed with a speed so ferocious, it probably breaks the sound barrier.
Honestly, the site of the spawns of Satan is literally offensive - even KILLING them feels like a terrible option because fuck those squishy yellow guts that explode everywhere. It's better to just burn down your house and start over.
And, if that isn't enough, these Kafkaesque fuckers can withstand 2,000 times the radiation level than humans and will probably, definitely outlive us all.
