Wow, what a great invention!! After treating my hives with the Mighty Mite Thermal heater, I have seen nothing but great results. The brood hives have exploded with new bees because the queen is now laying in all the frame cells and the Mighty Mite Thermal heater has killed all the small hive beetles in my hives. It is very easy to use and one thing that is very important to me, is I am now killing all the mites in my hives without using chemicals. With the Mighty Mite Thermal heater and the Beetle Buster Bottom Board, life in the bee apiary is great. I am going a save up my money and definitely purchase another Might Mite Thermal heater. Please feel free to come and visit any time you are in Missouri.
