'There is a great danger in using only one treatment of thymol - or
anything. In areas where there is beehives of many beekeepers ( or feral)
within flying distance, bees quite often collect mites after the early fall
treatment while robbing the colonies that are dying to mites. Oxalic in late
fall takes out these unwanted latecomers, which easily kill the hive early
next year.'
My original strategy was to use thymol in august and then use oxalic (as a
drip - for my safety!) in late autumn to clean up mites from re-invasion.
However, I have found this to be unnecessary and Stephen Martin in his
lecture stated the that re-invasion problem has been greatly exagerrated.
Whilst this seems to be true at least for this area of the UK, others will
have to make decisions based on the local conditions.
