Moths are considered pests because they can eat your clothes. Though personally ive never run into this because I've never had moths living in my house.

Moths are the one harmless thing I have an irrational fear of. A couple of times when I was very young a biggish moth got into my room a terrorized me (I'm guessing because of the way the light played off of my clothes).

I don't go out of my way to exterminate them, but if one follows me inside and resists my first couple of attempts to catch and release it, I'm going to smash the hell out of it.

I'm mostly over the visceral fear at this point, but if a big bastard is flying around a porch light I'm not sticking around.

Edit to add: I would probably smack a butterfly out of the air if it got in my face the way moths do. Equal opportunity irrationality.

I couldn't say why, but many of them freak me out. I don't tend to demand that someone kill it, but I feel the "ew."

I like moths. I think they are neat, and I really wish them the best.

Until they get in my room, and fly into my face when I'm looking at my phone in bed. Then its time for them to die, because they never follow light out of my room or respond to being shooed out.
