Made from essential oils, ApiLifeVar is a very effective treatment against Varroa mites when used appropriately. It's most effective in the fall when honey supers have been removed and daytime temperatures are still above 50°F.
Contains thymol, menthol, and camphor so it also treats tracheal mites and cleans up many bacteria and fungi.
Priced per package. You will need 1 1/2 packages per full-sized hive.
