Hi Steve
1) buy 500g of thymol put it in a large plastic feeder add 1 ltr that's 2x 500ml bottles of surgical spirit and stir.
2) decant the solution back into the bottles you will need an extra empty bottle because the amount of solution will be around 1.3 ltr
3) go to Lidl buy packs of 5 thin flat washing up sponges and cut each one into 4 pieces
4) put 2 pieces of sponge under the crown board at the back of the hive and using a syringe add 20ml of solution to each sponge.
5) wait around 3 days check varroa drop. If it is high then continue checks till daily drop is slowing at around 2 weeks repeat with another 20ml
6) the bees buzz a bit but are unharmed don't wait too late before application some bees wont come up to be fed while the treatment is on.
7) hopefully this will get you nice healthy winter bees and if you follow up with evaporated oxalic treatment in the winter no more deformed wings
