I just really hate mosquitoes. I get like they're a food source for other animals but they just suck so much. And gnats too. I live in a kind of hot/humid area and there are so many for most of the year and I get bug bit so bad. Plus mosquitoes spread diseases. I skin pick and I have so many scars from mosquito bites.
American cockroaches specifically, I think some types of roaches are pretty cool but those are the kinds that get in my house sometimes, and thier just to many of them
