Since they breathe through their exoskeleton, yes they suffocate fairly quickly.

or.... do they await their revenge and tell their young-lings to avenge them? Hmmmmm.... the answer is do you feel lucky?- well.... do you?

Probably—the suction injures them and they’re buried in a ton of crap that they suffocate them. :(

Some do, but some survive.

I once had lots of baby spiders in my bedroom and I sucked them up and then took the bag out and put it in the freezer (tied up in another bag) to make sure they didn't survive.

Spiders are both dead and alive when they're inside a vacuum cleaner

I hope so.

depends on how australian the spider is m8

probably not immediately, but I don't know how livable the inside of the dust trap part is for them

I guess they will not survive for long.
