If the colony died of mites or a virus from the mites, the bees are dead and so are the mites. Take the hive apart down to the bottom board. Have a cardboard box with you. Brush any dead bees and debris into the box with a bee brush. Lightly brush off any bees off the frames. Don't dump the bees in the beeyard. The dead bees contain nitrogen and are very good fertilizer. The dead bees will spur grass to grow in the beeyard and you will be mowing the grass more.

The hive will be safe to use for bees again. Re-use all the frames and honey.
