I mentioned earlier about finding plastic strips in a hive with a shallow super above. I was advised not to use it, and feed it to the bees. I have had the shallow hive body in place all summer, and am now feeding a 1/1 syrup to help them draw out the foundation. What do i need to do to get them to use it, it is full? I've also read to remove the shallow before treating for mites, which i need to do now.
