Researchers have found that as many as 40% of live young Varroa mites simply fall to the bottom of the hive, then crawl back up looking for a honey bee to begin feeding on. Catch those mites to eliminate them and also be able to answer two important questions:

1.) Do I need to treat with chemicals?, or 
2.) Did the chemical treatment work?
