In putting the hives in order for winter, Ive found a hive beetle infestation, in all the hives that I checked. Does coumaphos work in the hive.  What about outside of the hive on the ground, any known chemicals that can be sprayed.  I put all my hives on boards, trying to stop the trip to the ground, surrounding each one of my hive with at least 3 feet of wooden ground barrier.  If I was to move all of the hives out of a particualr area.  Will all the beetles be dead by spring, or do they just keep recycling.  We have very mild winters in South Carolina.  I never saw any beetles until now, and only in the one yard.  Any help will be greatly appreciated.  Walt in Sunny SC
