B401 (also known as Certan) is a preventative treatment that controls wax moth. It is a safe and environmentally friendly product based on a concentrated solution of Bacillus thuringiensis, a micro-organism. B401 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
B401 is made of spores from Bacillus thuringiensis and must be diluted in water to 5% (ie 1 volume of B401 for 19 volumes of water).
Shake the bottle of B401 vigorously before adding the required amount to the corresponding water volume and mixing.
Once diluted, the solution must be used the same day. Before mixing, calculate the amount of product required to treat the desired number of frames.
Shake the bottle before use.
Apply evenly with a sprayer over both sides of the frame.
Allow the frames to dry in an aired room before storing.
Safety of B401
Unlike paradichlorobenzene, which is a toxic product and forbidden in some countries for any agricultural use, B401 does not leave any residue in the wax or the honey.
B401 is harmless to bee larvae and adult bees.
Aizawai serotype 7 (present in B401) is the sole variety of Bacillus thuringiensis to give excellent results against wax moth. Some other types of Bacillus thuringiensis are toxic to humans & bees.
B401 is stored in a cool place (10 - 20 ° C) or in a refrigerator in its original original labeled package.
