Ouch! Sorry to read that. As above, if you're a member of your local BKA, chances are they've a swarm collection officer. If so, have a word. One of my strongest colonies came to me last June as a 3000 bee cast from a colony that's been in a nearby chimney for years. As luck would have it, the virgin queen had 5 good days to get well mated & she laid late & started again early. They're lovely bees. Good luck.
