"Daddy-longlegs" (meaningless term for any long-legged arthropod) do not have super-powerful venom, but no (or very weak) venom.
House spiders pose no significant danger to you, your children or your pets. Especially compared to your fellow humans!
No, those big, hairy, fast-moving spiders you see indoors are not wolf spiders (well, hardly ever). Most likely male house spiders.
Spiders in sinks and bathtubs come down the walls, attracted by water. They cannot come up through the drains!
If you put a house spider out in the yard, you aren't doing it any favor; it probably won't survive there.
Outdoor spiders are not drawn to indoor habitats where they can't survive. Indoor spiders are different species, called house spiders.
