I myself try to avoid squashing little bugs...but...now I have lovely 'Shaver Hens' and their very protective 'Rooster' and they just love to eat a tasty 'cockroach/spider/worm and all other plentiful bugs or two. I now leave them to feast on 'bugs' that I would have rescued/avoided in the past.
What we try to avoid squishing will be consumed by other 'bug' eating creatures.
