Members of PSBA educating on bees at the West Seattle Sustainability Fest, June 5, 2010.
Yesterday I spent the afternoon at the West Seattle Sustainability Festival, in the Puget Sound Beekeepers booth. Our club was there selling our club's honey and educating folks on bees. We had a couple of observation hives there, which seem to mesmerize all ages of people. (see pic above). When I signed up for the booth, I was actually kind of dreading giving up 2 hrs of my time on a sunny day in seattle...but, once there, I was immersed in telling everyone about bees! I ended up staying for 4 hours without even noticing the time pass. I guess I love talkin' about bees.
In the process, I think I unintentionally recruited at least 3 new beekeepers- all women- just by spending a few minutes answering their questions. (while eyes were glued to the observation hive- the bees were working their charm!) Each woman was extremely interested in bees. One even had previous exposure to bee research from her college days... but they all were hesitant to start into beekeeping, mainly because they didn't have enough info or support to begin as an urban beekeeper in Seattle. They thought it took alot of space or they didn't know where to start. I explained how I live in a condo and that I've leveraged my garden-rich friends to offer up space for my hives. I told them about our club meetings and beekeeping mentors. There were no more excuses...they each said they were going to be at our next club meeting to learn more- and to get started as beekeepers. how exciting!
While at the festival, the Frequently asked question I was asked, was what's killing the bees? quickly followed by, How can I help save the bees? (especially if I don't want to/can't be a beekeeper).
While I offered some good general answers to those questions, such as: support local beekeepers, avoid pesticides and plant friendly plants.... I wanted to be able to provide specifics. Hoping that, with specifics, people will more easily take action.
Thus, I'm pursuing a path of research and planning- to educate (myself) and others on possible causes for bee decline and how we can help- specifically. As a start to gathering such info: I used my break at the festival to check in at the Master Gardener booth. The gardener there seemed excited to help support me. I walked away with lists of bee friendly plants and a contact for collaboration in creating some educational materials for future booth events and beyond.
My initial research is below, for specific answers to "what's killing the bees?" and "how can I help save the bees?" (future blog posts will address additional ways we can help bees, as I continue to compile info):
In General- Avoid Pesticides:
Specifically- avoid neonicotinoids: Even more specifically, avoid Imidacloprid. I've read that pesticides of the class "neonicotinoids" are lethal to bees. Symptoms of this class of pesticides in bees includes death, and if not death- disorientation- i.e., not being able to get to food sources and back to hive- the very life of a bee. ( Of note: these symptoms are strikingly similar to the hallmark symptoms of "colony collapse disorder", or CCD. However, neonicotinoids have not been identified -as of yet-as the sole cause of CCD).
Neonicotinoids have been banned or limited from use in Germany, France and Italy, given concern over the lethal effect on bees, and health effects on humans. In those locales, bee populations have improved. See link #4 at bottom. However, the U.S. still allows neonicotinoids to be used (and plentifully) in agriculture (e.g., beets, corn), in termite control in your home, as well as in common lawn/plant care products - which you can buy in any hardware or lawn care store. (Imidacloprid is the specific neonicotinoid found in these products). Imidacloprid has even been found (and allowed by the EPA) as a contaminate in sugar, since imidacloprid is regularly used in beet production, ultimately ending up in beet sugar.(see health effects to humans in link #1 at bottom). This fact is important to you as a consumer of sugar and to beekeepers. (Beet Sugar comprises 55% of refined sugar consumption in the U.S., and Beekeepers regularly feed 1:1 sugar syrup to bees during times of low nectar flow).
Neonicotinoids are absorbed into the plant structure and soil (depending on the method of application). See link #3 and #4 at bottom. The pesticide will live there and be effective at killing insects over a long duration- meaning: treating a crop, tree, lawn, or plant with this stuff will cause pesticide to remain IN the plant or soil- and if bee comes in contact with it (or the pollen produced from the plant)...it means a likely death for the bee (and other beneficial insects- butterflies, ants, spiders, the like). This also means, even if YOU don't apply the neonicotinoid pesticide, you could unknowingly purchase a plant at the store which HAS been treated, and plant it in your yard. Perhaps unknowingly, you are wreaking havoc on insects such as bees. Scary. Even more scary are the effects of imidacloprid on humans- read content from link #1 at bottom of post.
What can you do to help bees (and other beneficial insects)? Avoid use of neonicotinoids, and buy plants which have not been treated with them. If you don't know, ask the producer of them. Rose bushes, Fruit trees, beets, & certain ground covers are commonly treated with imidacloprid as they are grown. (I'm working on a list of these plants). You should also know the common lawn and plant care products which contain neonicotinoid class pesticides. Once you do, you can avoid them and educate your neighbors about them. Here's a petition, urging for the ban of neonicotinoids.
The Sierra Club has a campaign to save the bees and recommends a documentary called "nicotine bees" to understand the impacts from neonicotinoids on bee populations.
In a quick jaunt to my neighborhood home depot and true value today, I documented the following products containing Imidacloprid. Please avoid them, for the sake of bees and other beneficial insects- as well as human health:
- Bayer Advanced, 12 month Tree & Shrub Protect & Feed
- Bayer Advanced, All -in-one Rose & Flower Care
- Bayer Advanced, Fruit, Citrus,& Vegetable Insect Control "Season Long Protection"
- Bayer Advanced, Complete Insect Killer for Soil & Turf ready to spread granules (comes in bag) "Kills insects up to 3 Months"
- Scotts GrubEx Season long Grub Control. Comes in bag, for spreading on lawn
- Ortho Flower, Fruit & Vegetable Insect Killer. "Kills 100+ insects on contact"
- Ortho Max Tree & Shrub Insect Control. "One application protects for 12 months"
Naively, before my trip to Home Depot, I'd hoped that most people had figured out ways around using insect killers (especially here in the ecofriendly and eco-conscious seattle). I'd hoped there'd be a sign saying- "we don't offer these products because....". If that didn't exist, I thought there wouldnt be that many imidacloprid containing products available -and there'd be dust on the products on the shelf.
Insead, to my dismay, there was an entire aisle devoted to these types of products- lots of stock, no dust. Curiously, I noticed none of the packages included a picture of a dead honeybee. They did have pictures of scary looking aphids and caterpillars - portrayed as the intended evil targets, though. I guess those marketing folks think putting a dead honeybee on the packaging would deter a consumers choice in buying, especially given all the publicity about bee decline and importance of bees on our food supply. No, I guess they wouldn't go that far in marketing all the possible impacts from using their products.
This was my first day on the task of documenting specific answers to "what's killing the bees?" and "how can I help save the bees?". I am no expert, but will continue to compose more specifics for your consideration, in future blog posts. In the meantime, I encourage you to do your own homework. Think through your day to day choices, and consider more bee-friendly (and human friendly) options, for all our sake.
Some resources I used to write this-are below in the links. Most of these are captured in my twitter feed (to the right) too. (I usually send them there first, when I run across them.) So , be sure to follow me on twitter, for regular updates on source info I discover. Over time- I'll recap what I find in blog posts, such as this one.
Follow me on twitter: @seattlebeeworks
From articles I've researched:
Link #1: great overall article on neonicotinoides, impacts and usage. Quote from Link: Sierra Club statement on Imidacloprid: "It has been shown to cause acute health effects, including spasms and thyroid lesions," the Sierra Club stated. "No chronic toxicity tests have been made available to the public, but we do know that it has effects on mammalian reproduction. The reproductive health of birds is also affected, with reduced egg production and egg thinning. It affects a multitude of beneficial insects, as well as earthworms."
Linke #2: Imidocloprid contamination in beet sugar. Quotes from link:
- "Imidacloprid is a powerful neurotoxin, lethal to bees in doses as small as five parts per billion, and has serious sub-lethal effects - including disorientation - at much lower doses. To put that in context, if you took ONE THOUSAND METRIC TONNES of 1:1 syrup made with beet sugar, and stirred in just ONE TEASPOONFUL of Imidacloprid, you would have a mixture capable of killing bees. Please read that last sentence again and think about it."
- "The US 'Environmental Protection Agency' has approved permitted levels of Imidacloprid in sugar beet of 0.05 parts per million - that is at least TEN TIMES the lethal dose for bees."
Link #3: Sunset Magazine Fresh Dirt: Quote from link: "Imidacloprid is a nerve toxin. It is highly toxic to insects, including beneficial ones such as bees. It persists in the soil and is taken up by plant roots and spreads to all parts of the plant, including the pollen"
Link#4: Bee populations restored with neonicotinoids ban Quote from link: "Nicotinyl pesticides, containing clothianidin, thiametoxam and imidacloprid, used to coat plant seeds, are released into the lymph as a permanent insecticide inside the plant. But after just sucking dew from maize leaves that absorbed neonicotinoids, disoriented bees can't find their way to the apiary. Massive numbers of bees get lost and die"
I'm still assessing the cause of the hive deaths: The 2 dead hives, on queen ann, still had some (small amounts) of honey in them along with some random bees, which were there to rob it (I perceive). There was No big cluster of bees dead inside and no evidence of a swarm cell. What I saw: Some honey, Some capped brood (dead) , robbers present (bumble bees, random honey bees (from nearby active hive).
Some possible causes, which I need to assess further/get advice:
- new queens I introduced in April Failed- not sure how to discern if this was the failpoint- need to ask mentors
- Starvation (there was evidence of bees w/ butts in air in search of food so this is a contributor, no doubt)
- Pesticides (I put this on the list because of no big cluster of bees in hive- despite big population in April)
If you have ideas, feel free to comment.

The Puget Sound Beekeeping Association is going strong and I've been elected to Vice President, so am looking forward to supporting the non-profit's efforts in educating the community and other fun beekeeping/honey events and mentoring of new beekeepers.
This year was a bad year for honey harvests, for most beekeepers. My mentor, with 8 hives, declared no honey harvest due to drought and weak hives. I was lucky to claim ~60 lbs from 4 hives, mostly medium to dark honey. (to compare: three yrs ago I had 100lbs from 1 hive!)
I'm currently in the process of bottling and supplying holiday orders, as well as preparing my usual supplies to Husky Deli in West Seattle. (Their holiday tasting event is Dec 4th 5-9pm)
Learnings this year:
- I suffered only one queen death this year, even before she was released in the hive- thus, I claim no fault, but learned I could get a queen "on warranty"- who wouldda thunk?
- One of my hives was pretty arnory-stinging me thru my gloves and very active/aggressive guard bees. I didn't do much to support this hive during this season, figuring they had it under control if they didn't want me visiting- so bee it. :-) (this obviously was the "lazy beekeeper" approach.) Next year, to remedy, I will likely requeen in the spring- that is, if the hives make it through the winter.
- I also learned that it isn't good to have a mixture of equipment sizes- especially when your hives aren't in the same locale. I prepared alot of shallow hive bodies, for honey supers this year... but found it frustrating to end up not having a western size when I needed, or the wrong equipment in the wrong locale, or mismatched frame sizes prepared. I may sell those shallows for westerns, to make it easier on myself.
- Honey Labels- design matters. I took a letterpress course this year to both foster a curiosity I had about this lost art, and to establish a new honey label design. My letterpress label turned out really cool, but more asian looking than I'd expected/intended. I learned west seattle buyers don't go for honey that appears is from Asia- my sales reduced as a result. (Read about china tainted honey imports to figure out why). Back to the drawing board on my labels- a good winter project.
I still love beekeeping, but I do think I am at my limit of hive count,given the lack of my own beeyard. I seem to get many offers from folks for hosting more hives in their yards...which surprises me, but am glad to see the support for bees.
If you are looking for a neat gift this year, don't forget you can always give bees!

Anyway on april 19th, I hived the 4 new packages and left the queens in their little cages so the bees could get acquainted with them, and improve acceptance. A week later it was time to release the queens. My friend who hosts the Admiral hive discovered my queen, dead in her cage :-( The other three hives were just fine, so not sure what happened there...
I got a replacement queen- under "warranty" as a result of this death, so early after receipt.
I will go back and let her out this weekend, and check the other hives to make sure the queens that did live are laying eggs.

I scheduled the extractor rental for the last weekend in october. I need to go by my hives this weekend and pull off honey supers..which should have been done a few weeks ago.
Now, I need to recruit helpers and a place for extracting. Now that my mentor lives in the boonies, I need a place to do the extraction. I am halfway tempted to go rent one of those storage units 1) to place all my beekeeping gear in it year round, as well as 2) to perform the extraction there. hmmmm. another thing for my to do list.
