Instead of wax strips you can use paint sticks from Home Depot, or cut your own. Just glue it to the top bar with food grade glue. No hot wax or chemicals. In 10 frame box , at the ends install drown frames, and 8 foundationless frames in between. When bees start drawing wax, remove those end frames, and let bees make 8 fat frames of comb honey. Tested it this year on one hive. Heavenly taste. Select strong hives in the strong nectar flow.
