Ladybugs have a weird smell when you handle them. Smells a bit like earwax.
Also, from the time when I hatched flies as food animals, flies really stink but you don’t normally notice because you don’t smell it when it’s just one. Put 100 flies in a bucket and they STINK.
No idea what’s going on with the ants though. I’m still not convinced this isn’t a hoax.
