Spiders don’t go around killing people.
Spiders simply defend themselves when they think they’re being attacked by a human.
They don’t deserve to die simply because they have a good defense mechanism.
Consider learning to catch them and release them far away from your house if you’re worried about them.
I hate to see the focus shifted to insects when we’re still trying to get people to stop torturing, murdering and consuming animals, but, honestly, if you don’t need to kill the insect just don’t.
In almost all case, you just need to take a little extra time to relocate it.
We both know you have the power to easily kill an intruding insect, but you also have the power to grant one continued life instead.
