President's Message - October

Fall is here again, it happens every year so it shouldn't surprise me. This summer just seemed to pass so quickly and with these warmer temperatures continuing as I write this, fall still seems a ways off. The calendar however does not lie and the days are noticeably shorter. The cooler weather that surely must be coming soon means less forage and less flight time for our bees. Because of this we need to monitor the weight of our colonies and feed if needed. A simple way to check is the two finger test, if you can lift one end of a double super colony then it's time to feed.

Hopefully everyone got varroa mite levels under control in August, but even if we have, we must continue monitor them. We want healthy colonies with plenty of food going into winter, this along with winter management will help insure they survive into next spring. If you have any questions about monitoring weight, feeding or varroa mites please ask at the next meeting.

Our elections for officers is held at the November meeting and nominations at the upcoming October meeting. If you'd like to consider yourself for a position please let one of the board members know at the next meeting.

Bee Bits - October

Wow, we got the first rainfall in September in five years!  It was stunning to go from summer heat to feeling like cold, dark, wet winter overnight.  But that bit of moisture was sure good for the vegetation.  Today I watched bees actively gathering nectar and pollen from Yellow Star Thistle, as well as some other plants.  
We just finished collecting final data on this summer’s trial of extended-release oxalic acid on shop towels.

Note: this method is not yet registered, and I am not suggesting that you use it.  I have a Pesticide Research Authorization from the State of California, and am merely giving a report on my research.

2019 Extended-Release Oxalic Acid Research Summary

We applied two half shop towels across the top bars, between the brood chambers, of double-deep hives in California, 1:1 ratio (w:w) of oxalic acid:glycerin,  total of 18 g OA per hive.  Trial ran from early July through early September, for roughly 60 days for each test yard.

In The Yard - October

I got a text this morning (September 28th) from a friend that I keep bees on her property, and said she had a swarm in a tree. She had sent a picture and it looked pretty small but I went out and hived it anyway. It was about 2 frames worth of bees, and I’ll be able to combine them with a small colony or maybe I’ll find a queenless one in the next few weeks.  Always seems mystifying why a colony would throw a swarm this time of year as its a pretty certain death wish if no beekeeper finds it.

I was camping near Ebbetts Pass in August, and saw honeybees foraging on this pennyroyal plant at about 9000 ft elevation. Pennyroyal was used since ancient times to rid the body of fleas. More recently it is claimed to be helpful as an insecticide and pest repellent and is used in some flea collars for animals. The concentrated oil of pennyroyal can be toxic to humans and animals.  Some people use it as an emmenagogue (your word of the day).
