Bioveta promotes BioKill in Pet Shops against fleas:
Their approach is to sell it as a duo packet with a one drop product. The idea is to explain that the treatment on the animal resolves only 20% of the problem and needs to be reinforced by applying BioKill around and on the area where the pet is sleeping. Like this the problem is not only better under control but also has a preventive character.
