Daddy long legs (Pholcus phalangioides) are fond my bathroom. I can normally coexist with them; they don't disturb me, I don't disturb them, and they're too much of a pain to move when they're on the ceiling.

However... sometimes, one comes in bearing an egg sac.

This poses a much more significant annoyance. The last time I tried moving one of these, it exploded into about three dozen spiders. I fled. That many spiders is too much for me. One or two I can coexist with. 28 like there were last time? No way in hell.

I don't want to kill any spiders, though. I'd feel worse about that than living with them while they move out into the great beyond. So, that being said...

How do I move the egg sac without:

• breaking the egg sac, or
• harming the spiders?

Capture the spider carrying the egg sac in a clear jar or tub, like those you buy cold things in at the grocery store or a medium-sized Chinese restaurant soup takeout container (after cleaning it out). I recommend plastic instead of glass so that it won't break if you make any sudden movements etc.

Slide a paper under the container as it's against the wall/ceiling/floor, so the big spider climbs on to it with the egg sac.

Then put something stiffer (like a thin hardcover book or clipboard) under the paper to help keep it flat against the bottom of the jar, and carry the mother and her sac all together outside. Set it all down, tip over the jar and if necessary gently tap to encourage the mother to climb out.
