I'm about to purchase a rental property. During the inspection, the inspector found bees coming out of the block wall where some conduit enters. I'm guessing they are honey bees. I've read that the honey combs should be removed, so the bees will not come back. I will not be able to do that in this case without destroying the wall. How can I get rid of the bees? Should I try exterminating them or call a local bee farmer/club to see if they want to remove them with traps?
