There are a few things that can lead to exploding mice.
1# Thawing the prey too rapidly, for example using hot water.
2# Thawing and refreezing the prey.
I raise, euthanize and freeze my own mice and when I thaw them I do so at room temp near the snake's enclosure and they never explode.
Fuzzies (and hopefully you do not feed those to a BP) thaw at room temp very rapidly there is really no need for hot water.
