North Olympic Peninsula Beekeeper’s Association (NOPBA) minutes

DATE March 9, 2025

TIME Noon

MEETING CALLED TO ORDER BY MARK URNES AND GREG BUTLER

IN ATTENDANCE – 36 PEOPLE

REPORTS – BUSINESS MEETING:

• Mark Urnes opened the meeting at noon. He welcomed 7 new people to the meeting and started the business meeting and introduction to the board.

• President – Greg Butler:

Bees are coming out. Check on their food now. You can put dry sugar on a piece of paper inside their hive. Be careful not to overfeed as the colony may grow too quickly and swarm.

• Vice President – Geoff McClain: Notify Geoff if you would like to be on the swarm list. The swarm list can be found on the website, NOPBA.org.

• Treasurer – Cathy Martineau –

1. Beginning balance $8,529.97, deposits $250.00 (dues), expenses - old fair expense,PayPal/Bank fees $424.98, Ending balance $8,354.99. We also have $75.00 in the cash box. Dues ($15/year for individuals, $25 for family, $150 for lifetime) can be sent to Cathy through our website (nopba.org) or in person by check or cash. Cathy will add members to the NOPBA email list. Check for an email once dues are paid. There are currently 140 people on the email list, which is being updated to remove those no longer club members.

2. Club members receive discounts such as 30% off the Cornell master beekeeper program and $5.00 off bees from Apex Apiary 360-460-7221 or website http://apex-apiary.com or on Facebook.

3. Mark Urnes purchased two hives for the prison program at $220 each. The club voted to approve the expense.

• Community Outreach – Megan D’Amore – No new report.

• Education Trustee – Rex Roberton:

1. Rex passed around sign-up sheets for those who want to mentor and those who want to be mentored (mentee) as well as a handout on the mentorship program.

2. Cornell University offers a one and ½ year online program for those interested in becoming a master beekeeper. Required prerequisite is 3 years beekeeping experience. This program is different from WASBA which people work their way up from beginner to apprentice to journeyman then to master beekeeper.

3. Next month (April) Rex will be doing a presentation on bee-lining which is capturing around 10 wild bees and then tracking their movement back and forth to their colony. This is in preparation for a youth program he will be leading in August. He is looking for volunteers who are interested in helping with the youth program. Good books on the topic are “Following the Wild Bees – The Craft and Science of Bee Hunting” by Thomas D. Seeley, and “The Bee Hunter” by George Harold Edgell.

• Social media – Rami Grunbaum: Rami posts sources to buy honeybees on our website nopba.org under “Resources”. Rami also posts the minutes submitted by the secretary under the “Home” page. He is no longer putting the minutes on Facebook due to member consensus.

• Secretary – Jamie Kenyon: Please sign the sign-up sheet and put an asterisk next to your name if you would like the minutes emailed to you directly. Jamie forwards the minutes to Rami, who posts them on the nopba.org home page and she brings a few hard copies to the meeting if you are interested.

PRESENTATION – GREG BUTLER – VARROA MITES, WHAT ARE THEY, HOW DO THEY DAMAGE THE HIVE, MONITORING AND MANAGING :

I. What is the varroa mite? Also known as Varroa Destructor, this is a parasitoid arthropod (8-legged spider) that kills its host (the honeybee). It is native to Asia and has traveled around the world on the backs of bees. It was first spotted in the United States in 1987 in Minnesota and has spread across the nation since then. The mite is visible to the naked eye, from 0.70 to 0.98 mm reddish brown to dark brown. They have a flat, spherical shape with eight legs and no eyes. They use their bulbous feet to stick to the honeybee. They cling between the bees’ protective plates to access the fat bodies of the bee.

II. How they damage the honeybee hive:

1. The mites feed on the bees’ fat bodies. The fat bodies of the bee help them to store and use nutrients in the form of fat, glycogen, and protein; especially important during larval growth; helps them metabolize carbohydrates, lipids, endocrine signaling and pathways; detoxification of plant defenses; and helps them survive the winter’s long periods of confinement. The mite carries diseases and 35 viruses, primarily deformed wing virus, which affects the pupa and causes them to be unable to fly, bring food, or pollinate, and unable to control the temperature in the hive. They weaken the bee’s immunity and shorten its lifespan. It also interferes with the bee’s memory and cognition. Once a hive is weakened by mite infestation, they are unable to defend their hive against predators such as wasps.

2. Female mites enter brood cells and lay eggs. Once the eggs hatch, they begin to feed on the larvae and reproduce. Once the mite reaches maturity, it will leave the brood cell and attach to nurse bees moving from cell to cell infecting other bees and brood.

III. Monitoring your hive for mites: Even though you may not be able to see mites, they are often hidden in between the protective plates and on the abdomen of the bee. Here are a few ways to monitor for them:

1. Use a screened bottom board to monitor mites that have fallen off bees. This method is not completely accurate, because it only shows the mites that have died and not how many are living among your bees.

2. Sugar shake method – does not kill your bees and allows you to estimate percentage of mites per bees.

a. Sequester the queen bee.

b. Shake at least 3 different frames of your bees into a plastic tub. Scoop up ½ cup of live bees = 300 bees.

c. Put the bees in a mason jar with a screened lid (#8 hardware cloth from Swain’s).

d. Add 1-2 tablespoons of powdered sugar and gently shake the jar to coat all bees.

e. Shake powdered sugar into an empty white plastic tub. Mites will be visible. You can add water to dissolve the sugar to make mites more visible. Count the mites.

f. Divide the number of mites by 3 to obtain the number of Varroa for every 100 bees.

g. For example, 11 mites will calculate to 3.6 Varroa/100 bees or 3.6%.

h. Release the bees covered in sugar back to the hive.

4. Soap wash or alcohol method – Allows you to estimate percentage of mites per bees but kills the ½-cup sample of bees. It may be worth the sacrifice to accurately assess your hive and protect them from infestation.

a. Obtain or make a Varroa mite Test Kit.

b. Sequester the queen bee.

c. Shake at least 3 different frames of your bees into a plastic tub. Scoop up ½ cup of live bees = 300 bees.

d. Put the bees in the test kit and put the lid on.

e. Pour over bees to completely cover either rubbing alcohol or solution of 2 tablespoons Dawn Dish Soap to 1 gallon of water. Gently shake the container for 60 seconds to allow the fluid to separate mites from the bees.

f. Remove the basket holding the bees and count the number of Varroa mites collected in the bottom of the bowel.

g. Divide the number of mites by 3 to obtain the number of Varroa for every 100 bees.

k. For example, 11 mites will calculate to 3.6 Varroa/100 bees or 3.6%.

5. When to monitor/check for mites: It’s very important to be in tune with how your hive is doing so regular observation is crucial. Here are some general guidelines of when to test for mites but you may do more or less depending on your observations.

a. During hive buildup March – April

b. During honey flow – June – September

c. During last brood – September – November

d. Broodless – December

IV. Managing Varroa Mites: 1% - 2% mite infestation is not an immediate threat to your hive.

If mite infestation is above 2%, then your hive may be in danger, and you should treat. It is crucial to get the mites under control by mid-July to August.

Treatment options:

a. Husbandry techniques – This is very effective but very difficult and labor intensive.

Rex is an expert in summer interruption of brood.

b. Bio-controls – techniques such as small cell foundation, powdered sugar dusting, hive scorpions, letting them swarm, resistant hygienic bees, and fungi have not been proven effective.

c. Essential oils – Thymol used in Api-Life Var and ApiGuard have been shown to be effective for 6 weeks when following the instructions on the label. It cannot be used during the honey flow.

d. Synthetics – Many synthetics are no longer recommended because the mites have built a resistance to them, and they contaminate the honey. Amitraz (trade name ApiVar) is still being used by some but will contaminate the honey and carries the risk of the mites becoming resistant.

e. Organic Acids – Oxalic acid (OA) is found naturally in many dark green vegetables, some nuts, grains, and legumes, in fruits, cocoa, tea and sweet potatoes. OA will not harm the bees and can be applied when honey supers are on the hive.

1. The most effective application seems to be the extended-release strips, which are not yet approved by the EPA. These strips are effective for up to 70 days and are made using vegetable glycerin, oxalic acid and Swedish sponges, all of which can be found online and are inexpensive. Some group members are willing to make these with members who have never made them before.

2. Dribble formula approved by EPA – must not apply too much or you can hurt the bees. Will last for about a week. Combine 4 tablespoons oxalic acid, 1 cup vegetable glycerin and 1 ½ cup hot water. Use a 50 ml syringe to dribble down each seam (between two frames). Must be applied at room temperature or a little warmer. This mixture will treat 10 hives. This does not penetrate wax cappings.

3. OA vaporization approved by EPA – Vaporizers can be purchased for $40 - $90.

YOU MUST WEAR A RESPIRATOR AND PROTECTIVE GEAR WHEN USING THE VAPORIZER. Effective but only last 3-4 days, so treatment must be repeated frequently. It does not penetrate wax cappings.

V. CONCLUSION – “Bee” ahead and stay ahead. Think prevention rather than cure.

BEEKEEPING TIPS, TRICKS AND QUESTIONS

SAVE THE DATES – August 14-17, 2025 Clallam County Fair – The theme this year is “Bee-lieve in the magic of the fair”. Mark is meeting with the fair superintendent and is looking for new ideas and people interested in helping with the fair.

There is a new mite called Tropilaelaps that originates from Asia and has been found in Georgia.

NEXT MEETING

The next meeting will be held at the Port Angeles North Olympic Library, 2210 Peabody St, Port Angeles at noon on April 13, 2025. Rex will do a presentation on Bee-lining, tracking bees in the wild.

Meeting called to order by 

  GREG BUTLER

In attendance – 26 People 

general information:

The presentation was before the business meeting because our speaker had a time commitment. See notes for the business meeting after notes on presentation. Megan D’Amore introduced our speaker, Carrie Morlang, owner of Knox Cellars Orchard Mason Bees.

presentation – carrie morlang – mason bees, how and why to get started

Carrie Morlang is the 3rd generation owner of Knox Cellars Orchard Mason Bees originally started by Brian L. Griffin. They are certified as ethical beekeepers by the Orchard Bee Association (OBA). She recommended two books by Brian L. Griffin: 1. Humblebee, Bumblebee; and 2. The Orchard Mason Bee.

A schedule of presentations and events can be found on the website:

https://www.facebook.com/knoxcellarsmasonbees/ 


  1. Lifecycle: Their life cycle is one year. Bees are active for about 9 weeks. Male bees live 2-3 weeks solely for mating. Females live about 6 weeks producing a total of 32-35 larvae.

  2. Hosting – put shelter and material out in February: 

  • Mason bees have a 30% success rate in the wild compared to a 90% success rate when hosted. It takes about 4 hours per year to maintain the highest standard.

  • Find a location for a shelter (3 elements): 1. On solid wall to protect from predators; 2. Protected from weather/moisture; 3. High enough so dogs/kids can’t disturb, but low enough to have at eye level to maintain.

  • They only have about a 150-yard range, so they need a clear pollinator pathway.

  • Material for optimal success in protecting from predators and disease – Must have 5/16-inch diameter hole and at least 6 inches in length. Three types: 1. Wood block, most economical, can clean and sanitize the same day; 2. Phragmite reed, favorite of the bees, single use; 3. Bee nesters system, water resistant cardboard tube with liner.

  • They will need clay/mud nearby.

  • Predators include pollen mites, chalkbrood spore, mono wasp and Houdini fly.


  • Keep the shelter in a cool, dry place until October. Then clean, sanitize, and inspect. Keep the cocoons in the refrigerator vegetable crisper drawer with a wet wash rag for moisture. The bees will be able to maintain a higher fat content if kept in the refrigerator.

  • When outside temperatures reach 49-55 degrees F for 3-5 consecutive days (late February, March or April), place cocoons near the shelter.


  1. What’s in it for me? Why keep mason bees?

  • The mason bee emerges much sooner than the honeybee and will increase the size and yield of fruit.

  • Sense of awe.

  • Support the natural, native environment – mason bees are native to this area.

  • They are very docile. The males don’t sting, and the females have no barb in their stinger with very little venom.

  • They are less labor than honeybees.

The presentation ended at 12:08 and Carrie was available to answer questions and sell material.

BEEKEEPING TIPS AND TRICKS

  1. Ordering bees – Now is the time to order bees. Some places to look are Ashley Baar (360) 460-7221, Sunny Farms, and Tarboo Valley in Chimicum. Bees will arrive mid to late April. A member would like to buy a queen but does not have any bees. It is necessary to have bees in order for the queen to survive. Dan Harvey is a local provider but will not have any bees available for sale until June or July.

  2. Can two colonies of bees be placed near each other? Yes

  3. Ground wasp issue – The best defense is to keep your hive healthy and they will defend themselves. If they are not able to defend themselves, it is most likely that there is a mite problem. Also, using an entrance reducer to keep the entrance to 2 ½ inches is helpful.

REPORTS – BUSINESS MEETING:

  • President – Greg Butler: 

The board met and came up with updates to the bylaws which have not been updated since 2020. Greg will send a draft with the changes red-lined and we can vote at our March meeting. Also, there is no longer a club library.

  • Treasurer – Cathy Martineau – Beginning balance $8,368.21, deposits $350.00 (dues), expenses USPS box $170.00, Paypal/Bank fees $18.24, Ending balance $8.529.97. Dues ($15/year) can be sent to Cathy via Paypal or by check or cash. Cathy will add members to the NOPBA email list. Check for an email once dues are paid.

  • Community Outreach – Megan D’Amore – Megan introduced Carrie Morlang who did a presentation on Mason bees.

BEEKEEPING TIPS AND TRICKS

1) Ordering bees – Now is the time to order bees. Some places to look are Ashley Baar (360) 460-7221, Sunny Farms, Dadant among others. Bees will arrive mid to late April. (For more options see the Sources for Honey Bees tab here.)

2) When should I open/check my bees in the winter? Try to keep the hive closed during the winter to conserve heat. You can lift you hive to see if it feels lighter due to the bees using their honey resources, Rex likes it to be in the 60s before he opens his hive. Do it quickly. If needed, give bees sugar on top of newspaper. Some people give pollen patties.

3) When to add honey supers – In May for June blackberries.

4) Classes to get certified and hopefully eventually become a journeyman beekeeper are being provided by SnoKing Beekeeper’s Association. There are classes via zoom. Contact Eli Ocheltree, Master beekeeper – (206)859-7392 or email eliochel@gmail.com.

PRESENTATION – REX ROBERTON – SELECTING AND MANAGING

HYGIENIC HIVES

Rex gave a very in-depth presentation on how beekeepers can control disease and mites by getting hygienic bees and managing them with summer brood interruption. In many countries, no chemicals are used. Instead, disease and mite control are through natural selection. Hygienic bees are more attuned to stress pheromones.

Some researchers/experts cited were Microbiologist George F. White (1906), Dr. Oscar Wallace Park, Dr. Walter Rothenbuhler, Dr. Thomas Rinderer (1977-2016 varroa resistance), Dr. Eva Crane (www.evacranetrust.org), Dr. Marla Spivak (Freeze killed brood), Dr. John Harbo (Harbo Assay, SMR), and Dr. Kaira Wagoner (Unhealthy brood odor).
