I am a new beekeeping person..... so please forgive the question ...but... if the bees are hanging outside the hive and it happens to be due to medication for tracheal mites and or varroa mites how is the medication able to impact those mites ????????? Doesn't this greatly limit bee exposure to the medicine and therefore negate the impact that the treatment actually has???
