I've never had to remove any type of arboreal Lizard/Gecko to clean its enclosure. If your giving them what they need, they'll retreat to wherever they feel secure and you go about your business. Once your done they'll eventually come back out and resume theirs. I did this for years when I kept Day Geckos. I never had an escapee and these things were 50X faster than an Anole. Some of them would sit and watch what I was doing, though I couldn't get all of them to take crickets out of my hand.
