This is the most important development in beekeeping equipment today that everyone should be using! The screened bottom increases brood production, reduces Varrora mite counts, allows you to better monitor your Varroa infestation levels, and enables bees to excel over winter! The included Corex sheet is printed with a numbered and lettered grid to ease the job of counting mites. Close them up with the enclosed Corrugated (Corex) Sheet when re-queening or starting a nuc or package. The rest of the year leave it open!
