If I release them outside and they die it would be a better death than staying inside and getting “played with until they don’t move anymore” by the cats, specially Pelusa Wakako Nimué Nonna Pocacosa who has appointed herself the house guardian against all vermin.
Their lives are not long enough to make that much of difference if they are deposited outside, if they are outside they are not laying eggs inside, and the nasty “bug-filled web in the face” effect is lessened.
ISTR some cute animals (seals?) carefully and lovingly cleaned and rehabilitated after being caught in an oil spill. And upon their carefully filmed release, being devoured all but instantly by waiting sharks or orcas or something.
Nature operates in bulk. The value of a single life is near enough to zero as not to matter at all. A beach plus or minus a single grain of sand is still a beach.
I think spiders are repellent and terrifying! But that’s no reason for me to murder them. Out they go to the yard, and no doubt are back in my bathroom an hour later. If not, well…lizards gotta eat too.
The spiders I release would have to be very fast indeed to make it back in as we have a healthy lizard population around our house.
ETA: Just for kicks, I googled and found out:
"Dung beetles do not intentionally kill or hunt spiders. However, fatal encounters can still happen:
Accidental Crushing: If a spider gets caught in a dung beetle’s path as it rolls a heavy ball, the immense strength of the beetle can crush the spider.
Territorial Clashes: Dung beetles vigorously defend their burrows and dung balls from any intruder. A beetle may attack, bite, or push a spider away if it gets too close to their brood, leading to the spider’s death."
Releasing bugs outside is a natural form of recycling. It quickly returns the creature to the ecosystem, instead of relative sequestration in a human dwelling.
Of maybe better note is the fact that when mammals- say skunks- are caught by a pest control company or the homeowner - and “relocated” they almost always die. Yes, wildlife experts can do that right, they scout out an area where the mammal might thrive, away for freeways, etc. Even so, it is traumatic.
I am sure the spiders just get eaten- the circle of life!
