GardStar® is a ground drench (DO NOT USE INSIDE THE HIVE) used to control small hive beetle larvae which pupate in the ground around the hive openings. It is also effective against adult hive beetles emerging. Each 4 oz. (118.29 ml) bottle makes 23 gallons (86.94 l) and 1 gallon (3.78 l) of mixture will treat approximately 6 hives. Sprinkle 18 - 24" (45.7 cm x 61 cm) out in front of hive entrances. Treatments last 2 - 4 months, depending on rainfall. If treating in an area where hives are already present, use a watering can to avoid any over-spray from contaminating the hives.
