Yeah I kill black widows. Not because of me, but because if one bites my kid, he's likely to get seriously ill, and be in danger.
Daddy long legs I put outside and on my house because they nest and keep bugs away. Nice.
My son currently saves frogs and snails and has a habitat in the backyard he dug himself. Hundreds of them live in there and it's crazy gross, but he likes it. So he does it.
