I can see it now, someone is walking on a sidewalk or some other place and they stomp on a bug for no reason what so ever. Why do they do that? Did the bug hurt them? Insult them? Scream at them? Kick them? Call them a name? No they didn't, so why do some people do it at all? It's plain being mean is how I see it. I have asked people in the past why they stomped on the bug and they shrug there shoulders at me and move on.
I can see killing a roach or even a house fly, as they carry germs, but butterflies and caterpillars, grasshoppers and lizards, they can do no harm nor do they carry germs, so the ones reading this that have squashed, mashed, and killed bugs for no reason at all, think to yourself, what are you going to say to God when he asks you why you killed one of his creations for no reason? If you don't believe in God, that's your own decision, but that doesn't give you the right to kill for the simple reason of killing. It's wrong!
Most house spiders are not harmful. The little spiders living in the corners of your room are your friends as they kill the little insects that get in and help keep your room clean. When you kill them, it's like killing the maid in a round about way. The larger spiders around your house, most are not harmful but they can be if they feel threatened, and so I can see ridding them from your house, but not killing them.
Ants are good and bad depending on the color of them. Larger Red and Black ants you don't want around as most will attack you first, so yes, getting rid of them is best. Bee's and other such stingers, they are pests and that's all, as most won't harm you if you leave them alone. Yellow Jackets, they are moody and some attack while others don't, but don't kill them for no reason. Don't piss them off when trying to kill them, as they have many friends who stand by them. Some will travel for miles to get revenge.
All the other insects, most are harmless. Please don't kill them as they are my friends just as all the animals in nature are. There are many mean and nasty animals in the wild, but that doesn't give anyone a reason to just kill them for the heck of it. Treat bugs and insects the same. They have a job here on the planet just as we do.
