They’re one of the few bugs that gets to live if it happens into my home. They don’t bite, they don’t fly around and get in your face or buzz around lights, they’re little and kind of cute. No reason to kill them, really.
Flies don’t have a cute factor. They get killed. Scorpions don’t get a cute factor. They get killed, and often tortured to death. Spiders, no cute factor: they get killed, except for people from countries where they’re seen as beneficial to human health because they kill mosquitos which transmit deadly diseases. Bees and wasps pose a problem: on one hand they are kind’a cute, on the other teaching kids (and stupid, uninformed grown-ups) how to tell them apart and that it’s a Bad Idea to try and smoosh one because that is when they bite has been known to cause some serious fights.
Ladybugs and escarabajos de san antonio (I don’t know what are they called in English, they’re the multi-segmented black ones that form a ball when poked) are cute and don’t bite, so it’s as if they have a Do Not Kill sign.
Note to anybody googling: I find images for “vaquitas de san antonio” which are ladybugs, the bugs I know as escarabajos de san antonio are completely different - but still cute. Heck, they’re used as a jewelry motif!
Those are the worst - the first few summers they showed up, I would be so happy, because Ladybugs are great!!1!
Then I got bit by one, and now I am death on Ladybugs. You can’t swat them because of the hard shells and the bite factor, and if you smash them, they stink in an Old-Lady, dead flower sort of way. Can’t vacuum them either, because your vacuum will then send that stink all over. We scoop them in toilet paper and flush them.
For the record, I don’t kill spiders unless they’re on my face or something. If I get one on my arm, I’ll flick it off, but never smash.
I don’t know how wide-spread this is, but when I were a lad we were told that very tiny spiders were “money spiders” and that if you could keep one on your hand for [some period of time that I’ve forgotten– probably a minute] it brought good luck and you would soon come into some money. And, of course, there was “Incey Wincey (or Itsy Bitsy) Spider”.
So small spiders, good – large spiders, bad, apparently.
I mentioned that on the superstitions thread the other day too - let the money spider run across your palm and you’ll get money. Spiders are much cuter or at least less creepy the smaller they are, when you can’t see those eyes and pincers.
They significantly reduce the aphid population, among others. Most nurseries sell bags of ladybugs to release among your plants. It’s quite a sight to see them swarm up a tree from where you’ve released them; it must be like what the Mongol hordes looked like to the rest of Asia.
