In the rush for complex solutions, traditional ideas are often overlooked...
Plain beehive bases work very well. Especially in dryer, colder climates not subject to large infestations of Small Hive Beetles.
This base consists of:
1" riser wax dipped and painted
masonite base board
Cypress pine cleats
Fully assembled and ready to use. This base is a cheaper option for those with large hive numbers, or on a budget.
Add beetle traps if Small Hive Beetles are an issue.
