Although its still winter you should be prepared to do a mite check this coming spring. A "powdered sugar roll" is a simple and easy way to check mite levels. The equipment to perform a powdered sugar roll is relatively inexpensive or you can make your own. (A 11/11/2016 post in this blog showed how to make a mite checker.) For instruction on conducting a mite check see the following link. Remember a mite treatment of some form is recommended if you detect a mite level of more than 3 percent.
