Did you know that no amount of fertilizer or water will produce abundant flowers and vegetables without pollination? For pollination, you need bees. We must have bees to help pollinate our crops, plants, and trees. 75-80% of all plans and trees require pollination from insects. The sad news is that our pollinators are in trouble! The use of harsh pesticides, mites, fungi, and habitat loss is believed to have resulted in declines in our pollinators including many species of bees. Planting native plants, installing bee houses, and providing our pollinators with healthy habitats will all assist in helping our bees.
WBU Barrie is proud to offer the following products to help these precious pollinators.
Several species of bees, butterflies, and other beneficial insects will also use houses. The sight of these little colourful gems in the backyard is a welcome sight by gardeners and nature enthusiasts. Attracting bees and butterflies into your yard is a great way to pollinate the plants in your garden, enhancing flowers and vegetables. Using bee and butterfly houses also helps to increase the biodiversity in your neighborhood.

Live Mason Bee Cocoons
WBU Barrie is proud to now offer Blue Orchard Mason Bee cocoons. This species is commonly found in North America and can be released in your garden to successfully pollinate your flowers, trees, shrubs, as well as fruits and vegetables. Pollen bee cocoons should be released when conditions are optimal, when daytime temperatures have reached about 10-13°C (50-55°F) or 10% of spring blooms are happening. The pollen bee cocoons must be protected until they hatch or they risk predation and illness. They will need some type of emergence chamber to protect them. Emergence chambers can be purchased from WBU Barrie (see our description below) or can be made at home. Set emergence chambers on a shelf away from predators and close to a pollen bee nest. Female bees will return to the area they hatched to lay their eggs and having a pollen bee nest available to them will ensure the bees continue to flourish in your area.
There are 10 Blue Orchard Mason Bees cocoons per package. Blue Orchard Mason Bee cocoons must be placed outdoors no later than June 1 (we recommend releasing them by May 1, conditions permitting) to complete their life cycle.
Mason Bee Cocoons are a seasonal product and are only available from mid April until mid May.

Mason Bee Mud Box: The mason bee protects each nesting chamber with clayey mud. Without a source of moist clayey mud nearby, mason bees will fly away! It can be a struggle to maintain the correct moisture content of the clay, but the Mason Bee Mud Box solves this challenge with capillary action! Water stored below the mud takes an elevator ride up the black cloth, runs horizontally under the clay allowing the clay to wick up the right amount of moisture. Depending on weather conditions, the water level in the storage bin may last one to two weeks before refilling is required. Includes Mason Bee Mud Mix! To use; simply open the top of the bag of Mason Bee Mud Mix and add water, kneading the mixture within the bag until it has the consistency of dough. Roll the mud into a 1" thick log. Place Mud Box within an 8m (25’) radius of your mason bee house, in an easily seen area with partial shade.

Spring Mason Bee Mud Mix: Spring mason bees use moist clayey mud to protect each nesting chamber. The female mason bee is very picky when selecting mud. She prefers clayey mud, not just clay or wet dirt. Our Mason Bee Mud Mix packs well and retains water for stickiness. Ensure that your yard provides a clayey mud source. Using a trowel or shovel, open a small hole in your soil and wet it to check for consistency. If it does not stick together when wet and pinched, add Mason Bee Mud Mix to the hole in the soil; or pair with the Mason Bee Mud Box for a set it and forget it solution! 7oz. of dry clayey mud that is perfect for your nesting mason bees. Beneficial for gardeners with sandy or loamy soil.
Weight: 7 oz. of clay.

Armstrong and Blackbury Pollen Bee Nest: Did you know that no amount of fertilizer or water will produce abundant flowers and vegetables, without pollination? For pollination, you need bees. Armstrong and Blackbury Pollen Bee Nest has been developed to attract a variety of wild pollen bees to your garden and vastly improve pollination of your plants. The proprietary granular volcanic rock filler prevents moisture from destroying the nests and developing bees. The filler, and excellent insulator, allows bees to overwinter inside the nest. This scientifically-designed nest eliminates most problems associated with natural or wooden man-made nests. The nest can be left in place year round, only needing an annual cleaning. Armstrong and Blackbury Pollen Bee Nest can produce 100 to 150 pollinating bees per year. This pollen bee home is proudly made in Canada.

Help your garden and the environment this spring! The scientifically designed Pollen Bee Nest is more effective than natural or wooden man-made bee nests at providing a truly protective nesting place for native solitary pollen bees. This nest has been developed to attract a wide variety of these gentle pollinators to your garden. The nest tube sizes, the proprietary volcanic rock filler, the specific color and pattern on the outer nest housing – all are the result of extensive research and testing. Inexpensive Solitary Pollen Bee Nests will improve your garden and the environment by supporting the natural life cycle of native solitary pollen bees.
Armstrong and Blackbury Pollen Bee Nest Emergence Chamber: The Armstrong and Blackbury Pollen Bee Nest Emergence Chamber is a dark box/cover with a small hole at the bottom that fits neatly onto our nest. It allows the new bees to emerge from the nest but does not allow them to return. Once all the bees have emerged out of the chamber, the tubes will be empty and ready to clean. Armstrong and Blackbury Pollen Bee Nest were designed to be mainly maintenance free but, over time, debris and mites can build up in the nest tubes. An Armstrong and Blackbury Pollen Bee Nest Emergence Chamber makes the nests easier to clean and allows you to further help out the pollen bees. TIP: Newly emerged bees will begin looking for a nesting site almost immediately. Placing a new (or previously cleaned) Bee Nest near the one covered by the Emergence Chamber will allow the emerging bees to find a new home right away.
At the end of a season, when all the tubes have been filled or activity has died down, slide the Emergence Chamber over the end of the nest. Leave over the winter and 
the new bees will emerge 12 months after they were laid the previous year. If you use the nest log provided to note when the tubes were filled, you will know when the new bees will be ready to emerge, leaving the Bee Nest empty and ready to clean. Once you think all the tubes are empty, remove the Nest and Emergence Chamber and take somewhere suitable for cleaning. (If you leave the nest in place to clean, you may find new bees trying to use it before it is clean and dry!)
Cleaning the nest requires reaming out each tube with an appropriate sized drill bit. Blow out the debris with an air hose or a gravy baster. Using a pipe cleaner dipped in a bleach solution of one tablespoon of bleach to 8 Oz. of water, lightly dampen the inside of each tube, being careful not to get them too wet. Allow at least two hours drying time or longer. Once dry, use a pipe cleaner dipped in the proprietary miticide powder to apply a light coating to the inside of each tube. Remove any loose powder by giving a final blast from the gravy baster and the nest is ready for reuse.
Contents of the Emergence Chamber Kit:
- 1 Emergence Chamber
- 4 Pipe Cleaners (of difference diameters for cleaning out the chambers)
- 1 Package of miticide
- 1 New Decal for the original nest exterior
- 1 Strip of 20 Bee Dots to cover the tubes
- 1 Detailed instructions about the Emergence Chamber
- 1 Nest Log

Organic Miticide: Organic Miticide in a powdered form can be used to clean out bee houses and rid them of mites which parasitize the bees. It is particularly helpful for bee houses that cannot be cleaned with bleach and water or where tubes cannot be replaced. Before using Organic Miticide make sure there are no bee eggs, larva or cocoons in the house. To help ensure this it is helpful to rotate bee houses through a 1-year cycle. Made in Canada.
