Though my brothers (now previous cat) didn't destroy things during the
night, she was a pest. So she, along with her food, litter box and toys was
confined to the laundry room each night. She would protest a bit in the
beginning, but eventually realized that all of the whining in the world
wasn't going to change the fact that at night - she had to stay in her room.

I don't know whether or not doing this would be an option for you, but it
did work for my brother.

If possible, you can confine them to a special room. Put in plenty of toys,
and beds
but nothing else. Maybe even a large cage, failing the room idea. Maybe
another
cat is roaming around outside at night and stressing them out, or maybe they
just want to play.
Cats are usually most active at night, so it is not unusual for them to have
a 'mad half-hour' and rush around like lunatics
at this time. Also, locking your cat inside some nights and not others is
not fair on the cat. Cats need routine.
Either lock them in every night - or leave them out.

How long are their claws?
Are they spayed yet?
Often, that helps considerably in calming them down.
They most likely want out at night because they're in heat, and want a
mate. Spaying them would eliminate this problem.
