I believe Steve Taber claims that young larvae and eggs are not very temperature sensitive. As I recall, he said that if wrapped in damp towel, a frame containing both can be placed in a refrigerator overnight and still be viable in the morning. His contention was that only a few moments of UV exposure (direct sunlight), or dehydration (wind) will kill them, and we call it 'chilling'. FWIW.
