Having noticed some Varroa at the inspection with Stuart, I returned the following week to check the mite drop count. To my dismay, there were approximately 100 mites dropped in a week. This was a high count and required action immediately. Fortunately, I had already purchased the relevant medication so I applied it that day, along with a 2:1 sugar solution in a rapid feeder above the top brood box.
The medication is administered via strips of plastic impregnated with a chemical which slow releases over a 42 day period, killing several successive generations of Varroa mites. Two strips are suspended, per brood box, between the frames in the heart of the brood. By adding the feed, it encourages the bees to be active in the hive, thus distributing the medication quicker.
Now the season is coming to an end, I’m trying not to open the hive too many times and have been enjoying observing the bees flying to and from the hive. I went down on Monday this week and what a stunning day it was! The hive is in such a beautiful spot. The bees were flying in with pollen and those who looked slightly drunk, fluffing their landing, must have been full of nectar! I noticed the ivy was beginning to flower and although the bramble bushes were no longer flowering, the brambles near the hive have had an exceptional bumper year, possibly thanks to the close proximity to the hive. My apple and bramble crumble was delicious.
The purpose of this visit was to check the Varroa mite drop and again, there was a high count but I’m assuming this was due to the medication kicking in! There was also quite a high count of chalk brood so the hive must still be stressed. Hopefully now the treatment is in place, the bees will recover.
The treatment is due to be removed no later than the 28th of October. This is to avoid encouraging the development of resistance. If the medication is over used, the effectiveness diminishes. However, between then and now, I’m hoping to open the hive a few more times to say hello before we part company for the winter.
