How do you clean the honey after the pest control has removed the bees and hive from inside the ceiling?

If they used chemicals to remove the bees, the honey is going to be contaminated with them and should not be eaten.

If they used physical means to remove the bees and hive, then place the comb in a large pan, MASH the comb up to insure that all the cells are open and GENTLY heat it up, slowly.

The wax will melt. Cool the whole pan down and you should be able to lift out a single block of bee's wax. Strain the honey to remove the rest of the sediment and enjoy.
