Hmmm... Now I know why Finsky got so angry off with his advice to forum members about mite treatments. I have posted several times about mite controls. I will continue to try to help. Apiguard (tymol) is a very good mite control measure. It is not chemical oriented like comouphous or fluvalonite. It works in other ways. So does formic and oxalic acid. These three chemicals are "natural", meaning, found in nature, excellent means of mite control. The mites do not build up resistance to these three assistances. But....temperature oriented.
Take some time. Do some research. Again, I will post a favourite site of mine that will give so much information about mite control methods.
http://www.mitegone.com/The author of this site will teach many good lessons, listen, read and learn, come on, take the time. To become a good beekeeper, you must be informed, you must study, take the wintertime to take this in your hand and roll with that ball.
I was the worst beekeeper during my first year of beekeeping because I was uninformed. I had taken Beekeeping Level 1 and 2, as many seminars I could get my hands on, and read many, many boods. But...I did not fully realize the magnitude of understanding the biology of the bee, how our inattentiveness affects the bees. I was not fully aware of how much damage can be done by not taking full control of the Varroa Destructor mite issues, I just thought I would let the bees be bees. I learned valuable lessons, and during that summer after my second year with the bees, I lost 8 hives due to the Varroa Destructor mite. I learned some valuable lessons during my first one and one half seasons -- I am still on that tip of that iceberg.
I get rather long-winded, and for this I apolgize, just putting my thoughts onto the screen of my laptop, hoping that some words may make some sense. Have a wonderful day, most beautiful of this life. Cindi
