After lunch on Thursday I dropped a level to Intermediate in order to enjoy a very lively talk by Eleanor Attridge on Varroa Treatments. Eleanor is the FIBKA Bee Health Officer. Her lecture was based on treatments currently legal in Eire and so, if you’re not there, you need to check your local laws before following her advice.
Medication is a last resort and some beekeepers have reported problems with medication. With new products some beekeepers weren’t applying them correctly. Instructions must be followed exactly. 18% of beekeepers aren’t using medication.
MAQS (Mite Away Quick Strips) are a strong formic acid treatment. There must be 6 frames of brood in the hive when using. 2 pads per brood box at a temperature over 10C.
Oxalic acid is not licenced, only Apibioxal.
COLOSS returns are showing that unapproved medicines are being used.
Bayvarol – 4 strips for 4 weeks. Beekeepers forget to take the treatments out and don’t rotate the treatment with others, resulting in resistance building up.
Apiguard is a thymol gel. 1 tray for 14 days followed by a second for 4 weeks. The temperature should be at least 15C.
Apibioxal. Mix 1:1 sugar solution with the product and dribble 5cc per seam, strangely like the Oxalic acid instructions. You can also use it for vapourising.
Varroamed is a new one.
Apivar – 2 strips per brood box. Change the frames in the spring as it contaminates the wax.
It’s important to use a range of medications (or none) in rotation to prevent resistance building up in the mites.
Then it was tea break. In one of the shops I bought a feeder device that fits on a water bottle.
Then the Queen knighted me! As I bowed before her she patted me on shoulders and pate and commanded “Arise Sir Chris.”
