Bringing orchids inside -- pests?

Also, a few of my catts don' look good - leaves loor brown and somewhat transparent, like half of a plant is rotting top-to-bottom. They are in a pretty big pots - should I repot in October?! What could it be?...

Always a good idea to post a photo with a question like this so that you get the best advice for your particular situation. So, if you can, post up a photo. I would also suggest for a new question like this to start a new thread.
