Yes, I drop both mice in front of his hide (about 3-4 inches away), he will sniff both out, choose one, pick them up (and any, if not all, of the substrate comes off), and he will drag it into his hide, and then eat it.

You could also switch to paper towels, but I've never had any issues with aspen, and I prefer it over most other substrates.
