Ideally yes. However advice we have been given that if you have a wasp issue then you can reduce the entrance but open up the varroa board so you ventilate the hive that way.
on the packet (bought from Thornes) it says "1 strip every 7 days for each beehive. complete treatment 4 strips for each beehive." this is twice the dose and different from your video. the ones I got are Lot 080323 exp 04/2025. Can you comment on this discrepancy. I dont like deviating from instructions on the packet, but 4 strips per hive effectively makes it twice the cost that you indicate on website and on this video
@@conallflickr I agree, the video could be clearer on dosage. It didn't say put the second block on after a week. Seems strange to have 2 blocks in a pack when the dosage is 4 blocks
