Furthermore on the subjects of how Mario characters would react to creepy crawlies in the house, I imagine Peach is the type that would lecture her friends about how nice spiders are and are beneficiaries of the ecosystem but Daisy really doesn't care and would gladly use insect spray and also remark that Waluigi's shops are probably full of them, so "if you love them so much, why doesn't you try living with them?".
Rosalina doesn't really touch insects, but there's one thing she can't stand, and that's silverfish, because silverfish love old books and I imagine Rosalina's library is full of old books.
Toadette is the type who want absolutely nothing with any creepy crawlie and would scream to Toad for help.
Wiggler absolutely freaks out over spiders and wasps even though she probably doesn't realize that wasps control the pests in the garden Wiggler always seems to tend.
I think Wario is that person who'd eat bugs or try selling them for money.
Bowser, who doesn't really care about the state of his castle, is cruel to bugs and gives magnifying glasses to Bowser Jr., Bowser Jr. is like his dad but Bowser Jr. loves playing "pretend the bug is Mario" which isn't really fair to the bug, but such is the unfairness of life, I guess. Kamek really thinks this is all petty, but he's also probably tasked cleaning the castle regularly so Kamek has to deal with a ton of spiderwebs and all, which isn't too bad because he has house-keeping magic that even Peach would be jealous of (and Kamek has nice, dainty laundry to tend to, so learning such powers is mandatory for him).
Dry Bones absolutely hates it when flies and ants try using its skull as a nesting place, but wouldn't go out of its way to kill them. Aside from that, Dry Bones actually doesn't mind bugs and all because it spent a lot of getting to know the bugs in the soil long after it was dead anyway.
