Anyone tried ladybugs indoors?

I've been thinking ahead to this winter and wanted to ask if anyone's ever tried ladybugs indoors (garage, greenhouse) for the control of both aphids and spider mites?

I don't like using all the sprays in the garage, plus they rarely seem to be very effective for me. I've tried Neem and Soaps, it's just hard to fully cover the plants adequatly bc of their large size. I have a lot of palms I bring in for the winter and the spider mites always seem to feast on them. The aphids always attack my softer tissue plants like the bananas and such. I also have had a lot of problems with mealy bugs lately.

I have been reading and I think I may give the ladybugs a shot. I know they won't eliminate insets, but figured they might keep them in check. Just curious if anyone's tried them. I was thinking of ordering 500-1500 and releasing them about a handful a week at night when the halides were off. Hoping maybe they'll feast on the aphids/mealy bugs/spider mites and finally give my plants some relief.

Up here people spray around the foundation of the house to keep them out. They will fill up the house if given a chance. Crawl all over the walls & mess the paint with their little secretions. Yuk!
Don't eat a single thing because they are trying to hibernate.

I hadn't thought about them trying to hibernate since it would be the winter time. Usually it stays about 70F in the garage all winter though, so hopefully they wouldn't try and go to sleep on me.
