Rhododendrons and Honey Bees

We just had 20 rhododendrons planted in our yard. We have been keeping bees and harvesting their honey for 3 years and love it. Now we heard that rhodies are toxic to bees and can contaminate honey. Should we replace these plants with other native species? The bees are very important to us.

Fogging varroa with oxalic acid

The most popular formula for fogging verroa seems to be 25g. to 35g. oxalic dissolved in 100 ml. of 90% to 95% alcohol. Shooting an open flame at 180 proof alcohol mist seems to me to be highly explosive. Since the alcohol is merely a carrier for the oxalic, I would like to substitute distilled water at 100 ml./25g. My
questions are: would this be a safe substitution, and what would the optimum oxalic concentration be?
I will be using a Burgess propane fogger, appx. $60.00 at Rural King.

Every time anyone uses our wooden swingset, they get stung by bees. We have looked everywhere and cannot find a hive. The bees seem to be on the offensive and come after the kids, following them across the yard and on one occasion into the house. It isn't a swarm, per se, no more than 8-10 bees in any one instance. I don't want to just spray insecticide, but we can't find a hive to relocate. Suggestions?

Can they survive outside of nest/cocoon?

Sorry if some feel these are silly questions but I don't know much about larvae or the stages they go through, except that they eventually turn into an adult of the insect that laid the eggs. I have a mason bee house with a few grass carrying wasps nesting in it. There is another grass carrying wasp that has a nest in the split of a fence post located right by the bee house. I noticed it a couple of weeks ago when I was doing yard work because I saw pieces of grass sticking out of the split and I saw the adult wasp going in and out of that area. Today while I was raking up some grass clippings, I noticed a yellow looking worm/grub laying on the board below the split post. I walked over to get a closer look and saw another one laying right by it, along with some grass pieces and other material that looked like a nest. I scooped up the larvae and the material around it with a small garden shovel and upon doing that, I saw more larvae that had come out of their cocoons. I didn't know if they were suppose to be out of the cocoon this early or if it was the fall from the post that broke them open? Should I have put them back on the board where I found them laying or put them and the nesting material back inside the little cubby hole area where the nest was from the beginning? Are they suppose to be out of their cocoon this early and live like this until they're an adult wasp or are they suppose to stay inside cocoons until next year and then break out? Can they survive outside of the cocoon at this stage? Sorry for all the questions but I'm really interested in learning the answers. Thank you for doing what you do!

Toxic honey caused by bees foraging on English or Cherry Laurel

Dear Sirs or Madame, On the suggestion of the Oregon Bee Keeper's Association, I am forwarding the following question to you: "Can locating a bee box near a hedge of English or Cherry Laurel lead to the honey being toxic? I want to move a bee box so that the back of the box is near a hedge of English Laurel, a plant I have heard is poisonous. Could this result in the honey taken from that bee box being toxic?" I would appreciate any insight you might be able to share. Ted Job

Giant hornets

I am a beekeeper in western New York. I currently have 9 hives. I am 69 years old and have been working with honey bees for many years. I opened one of my hives today and found what I believe to be a Giant Japanese hornet. The hornet was dead and laying on the inner cover. I do have an ant problem so the cover had a lot of cinnamon powder on it. Therefore the true colors of the hornet is difficult to see. My question is if this truly is a giant hornet and if so, I'm sure there's more than one in the area and what can I do about it. I do have hornet traps out as I have had yellow jacket problems in the past.
