I used this before I knew about Exzolt. It was hard work clearing everything out the coop and then applying and the. Repeating the whole 3/4 hour process 5 days later. The mite kept creeping out of the perch joints and so it wasn’t so effective if killing any eggs or mite that were hidden. It did reduce them but so did the hot soapy water and disinfectant remove many and so did the DE both of which we do regularly. However by the time I knew about Exzolt and managed to locate some they had all gone with the combination of Dergall, cleaning out and washing in hot soapy water and The DE. They may just be hiding now in the joints - I’ve checked at night and no sig of them and no signs of blood on the perches either so have to assume they are either dormant or gone. However the effort vs the Exzolt is high and I would go straight to Exzolt next time - which I now have in the cupboard with a 3 years shelf life unopened.
