B402 (also known as Certan) is a preventative treatment that controls wax moths. It is a safe and environmentally friendly product based on a concentrated solution of Bacillus thuringiensis, a micro-organism. This product is sold as B402 (Certan) in the USA and B401 (Certan) in the rest of world (where available)

B402 is used after the honey harvest, when the frames are stored and kills young wax moth larvae. It must therefore be used before a wax moth infestation. A single application will provide very high efficacy against wax moth right up through to the following season. 

Applicators and mixers should wear long sleeve shirt, long pants, socks, shoe, protective eye wear and a NIOSH approved particle filtering respirator. Mix one part of B402 to 19 parts water (5% solution). Apply after frames have been extracted. Apply to both sides of frame, 1 ounce of fluid for deep frame, 2/3 ounce of fluid for medium frame and 1/2 ounce of fluid for shallow frame. Allow to dry before placing in storage. In warm conditions, once dry, supers should be protected from reinfestation by being wrapped or stored in an enclosed space.
