One must also be thoughtful, not quite the same thing.
I respect spiders, even though some of them creep me out a bit as they do most people. They are such sentient creatures! I find them very responsive to telepathic contact. And when I first self-initiated as a witch, I was guided by both spontaneous mental imagery and sightings of actual, physical spiders to put myself under the protection of the Goddess in her form as Spider-Creator archetype; therefore I feel a moral obligation to treat spiders with respect.
So in my house no-one is allowed to kill them. I would make an exception in the case of a venomous spider that posed a potential threat to people and/or pets, but the Goddess knows that and keeps them away. I do, however, communicate with any spiders I see in the house, to tell them that the cats or any visiting humans might do them harm if they saw them. 'Keep out of sight for your own safety,' I tell them. And for the most part they do, or scurry to get hidden if they happen to be spotted.
So I did the usual when I saw a small Huntsman in the loo about a week ago. (No, not right IN it: on the wall near the mirror over the hand basin.) I didn't think to take a photo, but it was about half the size of the one pictured at the above link.
It had probably come inside to escape the rain; they do that. I suggested it stay behind the mirror as much as possible, and so it did, sometimes coming out just a little. I would greet it in a friendly way and then forget about it.
Once it was on the windowsill, and ran like mad to try and get out of sight, until I told it to calm down, it was only me; just not to let anyone else see it. It stopped running, and thereafterI didn't see it for a while — until the day I pulled on the end of the roll of toilet paper, to discover 'my' spider clinging to the paper further up. I did let out a small squeal at that — but bear in mind, it was a very small Huntsman, so thenI just shook it off as gently as possible.
Again it disapeared for a day or so. Then I noticed a spot of fluff or dust in a corner. An insect, perhaps? Oh no! Could it be ...? Yes it was, all dried and dead with its legs curled in. As I disposed of the body I realised that we live in a house fairly devoid of insects. We have flywire screens; I have an arrangement with the local insects, along the lines of 'Stay outside or you're fair game'; and if any that count as pests do come in, I do indeed kill them.
My poor spider must have starved to death. What was the point of my making it welcome (albeit with provisos)? I'd have done better to put it right back outside again!
