Artiste Apis Mellifera = Crazy Comb Patterns!

One thing that new beekeepers should learn is to expect the unexpected. And while I'm not a new beekeeper anymore, there are still things that I discover inside the hive that baffles me from time to time. One is the crazy comb patterns that bees will create on frames. Like this frame for example. As you can tell by the color, this is a drone frame that I use for varroa mite control. But the ladies decided to use it for another purpose. It has become their artiste's palette.

This frame is in a one year old colony. I believe in being proactive to eliminate pest problems, so weeks ago, I placed the drone frame in the hive so the bees could draw it out. Then after the frame is drawn and the eggs are capped, you take it out and freeze it, then put it back into the hive. The hygienic bees remove the dead brood and the varroa mites too by throwing them outside the hive. But when I checked to make sure they were doing what they are supposed to be doing, this is what I found. I also found a similar pattern on the end of another frame. As you can see, the ladies even started making honey in the comb. And when I pulled the frame out and broke the wax bridge going to the next frame, the ladies took advantage of the situation and had a tasty lunch.

While I really don't want to quash their artistic side, I really wish they would use the frame for its intended purpose. Oh well. I'll just add the wax to my waste wax collection and use it later.

My new goodies arrived from Brushy Mountain Bee Farm!

So I went to eat lunch on Thursday and by the time I got home, I found two packages on my front porch. I was happy to see that my goodies arrived from Brushy Mountain Bee Farm which is located two hours from me in Moravian Falls, North Carolina. As I mentioned in a previous post, I wanted a spare hive in case I find a swarm somewhere, and now I have a fully complete set-up for when the moment arrives. As you can see, the only thing it needs is a fresh coat of paint -- and I've already picked out the color. Bright orange! The orange color like the breakfast drink, Tang. So between my lemon yellow hive, the upcoming lime green hive -- and the spare orange hive, I should have all the citrus colors in my apiary. It should look like a taste of Florida right here in North Carolina!

Thank goodness the pest eliminators I ordered arrived too including the ten pack of ApiLife-Var (for varroa mites) and the disposable Beetle Blasters. Brushy Mountain includes their own instructions with the ApiLife-Var, and when I opened the plastic package to read them, you can really smell the ingredients even though each one is sealed in heavy foil. Each wafer includes the active ingredients of Thymol, Eucalytol, Menthol and Camphor. It is all-natural, and the active ingredient is the Thymol..a more purified form of oil of thyme. You open one foil package (you cut the two wafers into eight pieces) and put it over the brood nest for 7 to 10 days for a total of three treatments (21 to 30 days). The only problem I've read about the pieces is that unless you staple them to the frames or enclose them in screen wire, the bees will try to carry it out as trash. So I plan to take an old window screen and enclose the wafers inside to they can't move it around. You also have to block the screened bottom board and reduce the entrance so the vapors will permeate the entire hive. I'm planning to put the AprLife-Var in the hive for the first treatment this Saturday. And I plan to post just what kind of reaction my colony has to it and what observations I see too. The Beetle Blasters are self explanatory, but in case you've never heard of them, you put mineral oil inside them and put them on top of the frames in the five. When the small hive beetles scurry through the hive, they try to take cover in the traps -- and they meet their demise by drowning in the oil. All I can say is, good riddance! Back to the ApiLife-Var, Brushy Mountain says that used correctly, it will kill 95% of the varroa mites in your hive and won't harm the bees.

Here is the new inner cover I ordered from Brushy Mountain called a Goble cover.  I like it much better than the ones I have from Dadant. This inner cover is a piece of 3/8" plywood which is glued and nailed into the outer rim. And as you can see, it has a hole in the front which acts as an upper entrance. Its a lot more solid than the Masonite inner covers from Dadant which buckle really easily from hive moisture (and I speak from experience). I plan to order two more of these inner covers this week for all my hives. I'll never go back to using the Masonite inner covers anymore. Plus you get a better deal with the Goble covers because they're cheaper in price than the Masonite ones.


I have no clue what kind of bush this is, but I know my bees love it! It sits in my neighbor's yard, just across her fence and directly behind my bee hive. I noticed a flurry of bees on it all afternoon. Not only was it popular with my honey bees, but it was full of bumblebees too and they all seemed to be getting along just fine. I went to get my camera and waited patiently to snap some pictures of them gathering goodies from the flowers but every time I would get poised, they would move around. Finally in frustration, I decided to snap a picture of the entire bush. But take a look at the top left of the picture (where I circled in yellow). There you can see a bee as she's flying away from the bush. Hey, it wasn't a picturesque as I hoped for, but I think you get the idea.

I didn't mention that I bought 20 Pierco one-piece frames for the brood nest of my new hive. I've read lot of good things about the one-piece frames, they seem to be the rave of commercial beeks, so I decided to give them a try myself. They're coated in beeswax, and as soon as I opened the box, you could really smell it. Let's hope they work.

Pictures coming of the new lime green hive which goes into service just as soon as I split my current hive!

Bee good, everybody!

I found my first cases of DWV or Deformed Wing Virus!

So for the first time in two years, I found my first bee with deformed wings. Not just one bee, I actually found a couple. Its just one more thing I'm seeing for the first time in the beekeeping world.

I found them during an inspection Friday morning to see how they fared after last week's hive box rotation. I just happened to catch something out of the corner of my eye that didn't seem right, and when I looked at the frame I was holding, I saw something slowly crawling across it. Unlike the other bees who were busy scurrying around, this one bee was moving at a snails pace. She wasn't like the other bees -- she had two small stumps for wings and was obviously having problems walking. I took my hive tool and flicked her into the hive top, which was laying upside down, because I wanted to take a really good look at her. Then I found a second one, she obviously fell off one of the frames and into the hive top too -- so I had both of them isolated. Sure enough, both had stumps for wings, and they were both very slow moving. I knew then that my colony has the beginning signs of DWV or deformed wing virus. It really was a pitiful sight to see and being the soft hearted soul I am, I felt sorry for them.

I knew that DWV comes from varroa, but that's about all I really knew. So I went online and also read some of my beekeeping books to learn more about it. To be honest, I always thought that a colony suffering from deformed wings was because the hive was slammed packed with varroa. Not so. Experts say that hives with low varroa counts (like mine have been) can still have problems with DWV. And in many cases, the colony will expel bees with deformities like those with DWV in order to keep the hive hygienic. Obviously they missed these two -- and I'm kind of glad they did. Otherwise I would have never known about the problem. 

Knowing I have to do something, but keeping it natural and not putting chemicals in my hive, I read up on a remedy for varroa called ApiLife-Var. You can find a lot of material about ApiLife online and in Ross Conrad's book on natural beekeeping too. ApiLife is a remedy that studies show to be 95% effective..and it contains all natural ingredients like thymol, menthol, and eucalyptus oil. Three treatments (7 days apart) are all that's needed. Ross Conrad recommends that ApiLife be used in the fall instead of the spring, but the product literature says it's okay to use it during the spring and fall -- and i'm not waiting until the fall to treat this colony.

In the meantime, I did a really heavy powdered sugar dusting, and I called Brushy Mountain Bee Farm and ordered a package of ApiLife. It should arrive this coming week or week after. I plan to put it in the hive as soon as the daytime temperature stabilizes in the 60s. I'll also treat the second hive once the new queen is placed there and she settles in...and now that time frame looks like early May.

Just a reminder to check your hives and make sure you examine your bees carefully. Just because your mite numbers are low doesn't mean you can't have bees with deformed wing virus. Hopefully things will be back to normal very soon and all of my bee creatures will be healthy and whole again.

Critters in my hive! My new book arrives in the nick of time!

When I attended the Certified Natural Grown workshop this past Saturday, January 9th, I thought they would devote more time to dealing with bee colony pests in a more all-natural way. And I was disappointed when they didn't. They spent more time dealing with the rules for the organization than anything else. I still haven't reviewed the meeting, but I plan to soon. You can probably tell that I'm not all that enthusiastic about the program as of yet...but keep in mind that its the infancy stage and has a lot of growing to do yet. But more on that later.

The temperatures here are finally climbing back up to the moderate level. Over the next few days the daytime temperatures are expected to climb back into the 50s, so I decided to remove the corrugated plastic from under the screened bottom board so the air can circulate again. The plastic sheet had been in place since December 31st, and I decided that it wouldn't be necessary anymore with the warmer day and night temps on the way. 

When I removed the plastic, I noticed a dark dot the size of a really small garden pea. Making sure not to drop it, I went inside the garage and grabbed my magnifying glass to get a closer look. You guessed it..it was a small hive beetle. Honestly I didn't know what it was at first, but the more I examined it (and looked at pictures on the Internet) I realized I found my first. The beetle was dead, possibly dying from the freezing cold we've had lately. I've always heard the beetles could be found inside the hive itself..but this one was between the screened bottom board and the plastic corrugated sheet I installed. That leads me to believe that it may have hatched on the underside of the stand where it is dark and out of the way of the colony itself. But its possible that it was inside the hive. The Florida Department of Agriculture and Consumer Services website says, "They have been shown to attack bumblebee nests in the laboratory, and have been observed to survive winters in the hive inside the bee cluster." So now I'm going to have to keep a closer eye on this situation. The last thing I want is a major invasion of these beetles in my hives. They're disgusting looking and obviously not good for the colony.   

Now remember, I put the plastic corrugated sheet in place on December 31st. So it had been in place for 13-days altogether. While I was examining the plastic sheet, I also found some dead varroa mites. How many? 67. So if the sheet had been in place for 13-days, and a total of 67 varroa mites were on the plastic, then I consider the count as rather low. I realize that some may say that my method of arriving at that conclusion may not be very scientific, that a 3-day count would be more accurate. But when you add the extra days to my count, I think a count of 67 is a low count. Still though, it looks like the first thing I will do after I split this hive in a few months is give them time to settle down, then do a thorough powdered sugar dusting.

In light of these developments, the book I ordered over the weekend, "Natural Beekeeping: Organic Approaches to Modern Apiculture" arrived from Amazon on Tuesday, and just in the nick of time it seems. Ross Conrad, the author, looks at holistic methods to keep our hives healthy and handle pests without chemicals. It is obvious that many people, like myself, prefer to steer clear of chemicals when it comes to hive health. I've heard nothing but good things about the book, and now I plan to delve into it and read some each night. I think I'll hit the small hive beetle and varroa sections first.

Enjoy your day and bee safe!

Inspection in a word: FRENZIED!

Thursday was the perfect day for an inspection here. It was sunny, the temperature was 71 degrees, and no wind. It seemed more like spring than fall, and I figured I would do an inspection and a powdered sugar dusting in case any new varroa mites have sprung up. So I suited up, lit the smoker, and went down to the hive. Things were just fine while I dismantled the hive components; I took off the hive top feeder, then lugged the honey chamber off, and got down into the brood chamber to see what is happening there. And here is what I found.

Pardon the slightly off-center angle of the picture above, but as you can see, and like I've said before, this colony is booming. If I didn't know that fall was coming and that a lot of them will die out before winter, I would swear this hive is a candidate for swarming. Is seemed that most of them were packed in the brood nest (above) and not all that many in the honey chamber. And shortly after I snapped this picture, there were so many on the tops of the frames, I would have to smoke them to run them down into the box. Believe me, after what I started out with, I'm not complaining at all. Just my observation that a lot of bees inhabit this hive.
It had been awhile since I'd done a full-fledged inspection, and it was obvious the girls had been busy in both chambers, but they were making their fair share of burr comb too. When I pulled the honey box off, I pulled apart some of the comb that was full of honey attacked to the bottoms of the frames -- and of course the dripping honey went all across the top bars. So I had to scrape it off and into a bucket, then I had to scrape it off the bottoms of the frames in the top chamber which is packed with honey. There you see the majority of it in the bottom of the bucket (which I use for yard work). You can see the bees at the bottom that just didn't want to give it up.


Here is where it gets interesting. As I said before, I decided to do a powdered sugar dusting to catch any mites, so after I scraped off all the burr comb, I started my task with the honey chamber. I put the powdered sugar in the sifter and dusted it, and it was like someone sounded an air raid siren. They went ballistic! Ahhh, but the best is yet to come -- I had to do the brood chamber next -- and I just knew it was going to be one wild ride. And I didn't disappoint myself -- it was! Look carefully at the picture (to the left of the hive body) and you'll see a bee butting my camera. See her?


After I smoked them down into the brood chamber, I powdered them as well. And while I was doing it, the roar of the buzzing was quite loud and it looked like I was in the middle of a swarm. Some flying around were white, some their natural yellow -- and all were totally irritated. The head butting was turned up a couple of notches..and I looked down to see my overall pants all dotted with bees. They were on my gloves, on my smoker, inside my tool box -- everywhere I looked, there they were. Although I've never received a sting wound on my skin from this colony whatsoever, I found one on my glove and spinning around -- she stung my glove and her stinger was still partially inside her and lodged in my glove so I pulled her off and scraped the stinger out of the leather. They were not happy.


Although I wasn't scared (actually I was fascinated) -- I decided that this was the time to close up shop. I put the hive back together again in the midst of this cyclone of bees, and as soon as I got it together, they started hanging to the front of the hive. As you can see if you click on the picture, they're all on the front of the hive, covering the front of the screened hive stand, and a few clumps were on the ground in front of the stand. Some were returning foragers with pollen on their legs, probably wondering just what the heck was going on, but I think its safe to say that 95% were the ones that just got a dusting.


Take a look at this one. Yeah, that's a lot of ticked off bees. I know why they're so many there -- as soon as the sugar dusting began they took to the air and were now returning. They were hanging everywhere, but the ones that really bothered me were the ones that hung onto the underside of the hive stand and the ones that clumped on the ground. What scared me, and I know it probably didn't happen, but it scared me nonetheless -- was that maybe the queen was under that mass. Could she have dropped off during my inspection? Did she flee when the sugar dusting started? But then I thought it out and realized that I never examine my frames over the grass, I always hold the frames over the hive bodies in case she drops, so chances are her lying in the front of the hive and in the grass seemed really remote.


Take a look at the girls festooning under the hive stand. I watched the bees on the front of the hive slowly make their way back into the hive through the hole in the mouse guard, but then I noticed this clump under the stand. As you can see, it almost looks like a tiny swarm of bees that you might find under the eve of a house or something. While I was being dive-bombed by other bees flying around, these bees didn't do anything other than hang on to each other and wait it out. I guess they were waiting their turn to get back into the hive...in a less crowded space.


Meanwhile, three bees followed me inside my house. I was able to get one of them back outside, but the other two I had to eliminate...which bothered me a lot. One reason I eliminated it is because of my significant other, who is just fine as long as the bees are outside. And the other is because I have a 13-year-old Dachshund who is almost totally blind -- so I just couldn't take a chance of him getting stung. Oh, and that didn't include the ones that flew around the back door for awhile -- almost like, "You invaded our space, so now its your turn, buddy!" 


In the end it took a couple of hours...but the majority finally made their way back into the hive. By nightfall, only a few guard bees were on the entrance going back and forth. And then today, things seemed pretty normal, a lot of flying around in the front of the hive and crawling up the front, but otherwise it seemed fine.


Truthfully, I don't know if my experience yesterday is normal or not. Since I don't have the luxury of a mentor, I don't have anyone to readily ask...so I have to depend on asking other beekeepers online for their advice. I can say that I've never seen my bees become this aggressive before...it was even worse than the time I accidentally banged the hive during an inspection. And I realize they're protecting their honey store and usually become a little testy in the fall -- so maybe it isn't that unusual after all. So maybe my first-time experience just seemed a little more ominous than it really was.

ADDENDUM: A few other beekeepers on the BeeSource.com forum tell me that they're running into the very same situation when doing their inspections now. It seems to be that "its our honey and our home...leave us alone" mentality (right word?) that the bees have this time of year. It usually disappears in the spring. So it may not be that unusual after all.


Comments and ideas, good or bad, I'll readily accept. Anyone have a simular experience? Please share your thoughts.


I'll BEE anxious to hear from you all!

To medicate or not to medicate: that is the question.

It has been a gloomy week here in the Piedmont-Triad. It has rained, rained...and then rained some more. I can only imagine how bad it is in Georgia where they're getting flooded by heavy rains. And since it has been so rainy, it has given me some time to think about my colony and whether I should take preventative measures and medicate it before winter. The question that keeps playing over and over again in my mind is...should I or shouldn't I? 

As I've mentioned before, I want to keep my colony as natural as possible, and I prefer to use all-natural methods to treat my bees. When the state apiary inspector came to inspect my bees, I spoke to him about medicating a healthy colony. In some books, like Beekeeping for Dummies, it recommends that you medicate hives in the fall and the spring, and it is best to treat your bees much like you would treat your pets...you should use preventative methods to keep your hives from becoming ill. Kind of like you would treat your dog to keep them from getting heartworms or rabies. The books recommend you be a proactive beekeeper, not a reactive beekeeper.  

But Don Hopkins, the apiary inspector, didn't seem to be too quick to recommend proactive colony treatments. While he didn't rush to tell me yes or no, he did give me a clear indication that if a hive is healthy, you should keep a watchful eye, otherwise leave it alone. And my hive is doing really well and I want to keep it that way, especially with winter on the horizon. But should I put chemicals in a healthy hive? Some sources say yes, others say no. It truly is mind boggling and confusing for me as a new beekeeper.

I read conflicting information about Honey B Healthy. Some swear that it is a miracle potion that bees go nuts over and makes them thrive in the hive. Others say it is a total waste of money, or to be more blunt, that it is a form of "snake oil" for honey bees. It runs in the neighborhood of around $20 bucks for the smallest container, and for that price, I would hope it would do something miraculous. I found the recipe for Honey B Healthy online, and when I called the vitamin store to price the key ingredients to make it at home, I discovered it would cost me more to do it that way and it would be cheaper to buy it ready made. Since I didn't speak to a single soul that's used it and found great success, I decided to forget about it. Maybe I'll try it in the future, but for now, no.

Apiguard. The one thing I don't have is a problem with varroa mites. I did a three-day test using a sticky piece of corrugated cardboard, and I couldn't find enough mites to do a decent count. I've already done a powdered sugar dusting in the hive and after I finished...it looked like whirling snow storm of honey bees. While I'm sure that Apiguard does a fine job for hives with a varroa mite problem, I don't think mine would benefit in the least from a treatment. And besides, many sources say that mites develop a resistance to varroa treatments over time, and the last thing I want to do is run out of options before there was a problem to begin with. So for now, I'm saying no to Apiguard.

One thing I would consider using in my hive is menthol crystals which is used to treat tracheal mites. I know a guy who lost his colony to these invisible mites. They basically get in the breathing tubes of the bees and suffocate them. The most recommended treatment for tracheal mites seems to be bags of menthol crystals (which comes from oil of peppermint). It is recommended that you put a bag in the hive when the daytime temperature is over 70 degrees. The crystals slowly evaporate and give off a gas which the bees breathe in and cause a decline in the mites. While it won't eliminate the mites, it will cause their numbers to drop. I am still mulling this one over since it is a natural way to treat the bees.

I don't think I need Fumagilin-B. It is an antibiotic used for the treatment of Nosema, an intestinal disorder of the honey bee. Usually if a hive is infected, it will have yellow or brown streaks on the front of the hive or the bottom board which comes from a form of bee diarrea. Nosema usually infects adult female workers. And sources say it rarely infects drones or the queen. It is recommended to use Fumagilin-B in the fall and spring and with with all newly installed bee packages. Since I haven't noticed any outward signs that my bees have a tummy disorder, it doesn't seem sensible to treat them for something they don't have. I will keep it in mind though. Beekeeping sources say that Nosema is more prevalent in overwintered colonies, so who knows what this coming spring will hold. Thank goodness I'm one hour away from the Chatham, Virginia, branch of Dadant & Sons in case I need a bottle.

I could go on and on, but the more I think about it, I really believe that I should leave my colony alone medication-wise and just keep an eye out for any possible problems. While I'm fairly confident that I'll leave my girls alone, I've also learned to never say never. I plan to continue my research to see if I'm making the right decision, but since we're already in autumn by the calendar (and the weather on some days too) I have to hurry. But I think I'm going to ride it out.

I would love to hear your ideas on medicating colonies and whether you do it or not. Please feel free to share!

Bee-have yourselves!
