Buzzworthy Abodes: A Comprehensive Guide to Attracting Bees to Your Bee Box

Bees, the tireless pollinators, are vital for the health of our ecosystems and the abundance of our gardens. As their natural habitats dwindle, providing them with suitable nesting sites, like a bee box, becomes increasingly crucial. However, simply putting up a box doesn’t guarantee that bees will move in. This comprehensive guide will walk you through the process of attracting these essential insects to your bee box, from choosing the right location to creating an irresistible environment.

Understanding Your Target Audience: Different Types of Bees

Before we dive into the specifics, it’s essential to understand that not all bees are created equal. There are thousands of bee species worldwide, and they have diverse nesting preferences. While honeybees (Apis mellifera) are perhaps the most well-known, they typically live in colonies within cavities like hollow trees or man-made hives. Here, we’ll focus on attracting solitary bees, which are the most likely to use a bee box. Common solitary bees you might attract include:

• Mason Bees (Osmia spp.): These bees are known for their gentle nature and their habit of using mud to seal their nest cells. They are excellent pollinators, especially for fruit trees.
• Leafcutter Bees (Megachile spp.): As their name suggests, these bees cut circular or oval pieces from leaves to line their nest cells.
• Carpenter Bees (Xylocopa spp.): While they are primarily cavity nesters, they might use pre-existing holes in wooden structures, and some types might utilize the larger tubes in your bee box. (Note: They can become a minor structural issue if they start making their own holes).

Understanding which bees you’re trying to attract will help you tailor your approach.

Step 1: Choosing the Right Bee Box

The first crucial step is selecting or constructing an appropriate bee box. Here are some key considerations:

• Material: Opt for untreated, natural materials like wood. Avoid chemically treated wood, as the fumes can be toxic to bees. Cedar, bamboo, or even dense cardboard can be good options. However, you must ensure that the materials are waterproof as well, which can be done by using a non toxic, bee friendly wood sealer.
• Size and Design:
  • Tubes/Holes: The ideal bee box will have a variety of tube sizes. Mason bees prefer tubes that are around 6-8mm in diameter, while leafcutter bees often like slightly larger ones (8-10mm). Offering a variety of sizes increases the chances of attracting different species. The tubes should be at least 10-15cm deep to provide enough space for nesting cells. It is also vital that the back of the tubes be closed as bees prefer closed-ended tubes.
  • Depth: Tubes must have at least 10 – 15cm depth for the bees to make their nests.
  • Spacing: The tubes must be spaced in such a way that bees can easily access their individual entrances. Too closely placed tubes can deter bees from settling in.
  • Orientation: Tubes can be oriented horizontally, but you should try and avoid having the tubes pointed upward, as this can allow water to accumulate inside.
• Construction:
  • Removable Inserts: If possible, choose a bee box with removable inserts. This allows you to clean the tubes annually (usually in late fall or winter when the bees have completed their nesting cycles), preventing the build-up of parasites and diseases. This also helps you monitor the progress of the nests.
  • Solid Backing: The bee box should have a solid back to provide protection and stability. Avoid boxes with open backs, as they leave the nests vulnerable to predators and the elements.

Where to Buy or DIY: You can purchase bee boxes online or at garden centers. However, making your own can be a fun and rewarding project. Many online tutorials and DIY plans are readily available.

Step 2: Location, Location, Location

Choosing the right location for your bee box is paramount for attracting bees. Here’s what to consider:

• Sunlight: Bees are cold-blooded and need warmth to be active. Place your bee box in a sunny location, ideally facing south or southeast. This will maximize sun exposure, warming the nesting tubes and encouraging bee activity. It should receive morning sun and be out of the shade in the afternoon.
• Shelter from Wind and Rain: While bees need sun, they also need shelter from harsh weather. Choose a spot that is protected from strong winds and heavy rain. Consider mounting the bee box under the eaves of a building or beneath an overhang. This will also keep the wood dry and preserve the box.
• Proximity to Food Sources: Bees are attracted to areas with plenty of nectar and pollen-rich flowers. Place your bee box near a garden, a wildflower meadow, or any area with flowering plants. Try planting bee friendly flowers near the box to increase the chances of attracting them. Native plants are particularly beneficial, as they are often best adapted to local bee species.
• Height: Mount the bee box at least a few feet off the ground. This will protect it from ground-dwelling predators and keep it out of reach of pets or children. You can either mount it to a wall or use a pole. Ensure it is secure and cannot fall or be knocked down.
• Accessibility: Ensure the location is easily accessible for you for cleaning purposes, which is best done in late autumn or winter.

Step 3: Preparing the Nesting Tubes

Once your bee box is in place, you need to prepare the nesting tubes to make them attractive to potential residents.

• Tube Material: If you have a box with removable inserts, ensure the tubes are either made of paper or natural materials. Avoid plastics as these can lead to condensation, which is bad for bee health. Bamboo is an excellent option for its natural construction.
• Cleanliness: Make sure the tubes are free of any debris or dirt before mounting them on the box. This is essential to invite bees as they are attracted to clean nesting holes.
• Inner Lining (Optional): For boxes that do not have removable tubes, you may line the insides with parchment paper. This will help with cleaning. You can cut the parchment paper into strips, roll them into a tube, and place inside the holes. Make sure to cut the paper long enough so that a small bit of the paper sticks out, which will help you remove the paper tubes from the nesting tube.
• Mud Availability: Mason bees need mud to seal their nest cells. If you don’t have a naturally muddy area, provide a source of moist mud nearby. You can do this by placing a tray of damp soil next to the bee box.
• Leaf Availability: For leafcutter bees, ensure there are plenty of suitable plants in the area from which they can collect leaves. Plants like roses, and clovers are good leaf source options.

Step 4: Providing Additional Attractants

Beyond the basics, some additional measures can help boost the appeal of your bee box:

• Bee-Friendly Plants: As previously mentioned, having a garden full of bee-friendly flowers is essential. Choose a variety of plants that bloom at different times of the season to provide a continuous food source. Include plants like lavender, borage, sunflowers, asters, and coneflowers. Native plants will always be the best option, so be sure to do your research.
• Water Source: Bees need water, especially during hot weather. Provide a shallow dish or bird bath with pebbles or stones where they can safely land and drink without drowning. Ensure that water is always readily available to bees.
• Bee Attractants (Use Sparingly): Some commercially available bee attractants can be used to lure bees. These products are often made with bee pheromones. However, use them sparingly, as overreliance on these attractants can be harmful. It is better to focus on creating a good environment for bees, rather than relying on artificial attractants.
• Patience: It can take time for bees to find your bee box. Don’t get discouraged if you don’t see activity right away. Be patient and let nature take its course.
• Avoid Pesticides: Do not use pesticides in or around the bee box. Pesticides are harmful to bees and can contaminate the environment. Instead, use natural pest control methods to protect your plants and your bee populations.

Step 5: Maintenance and Observation

Once bees have moved into your box, it’s essential to monitor their activity and perform necessary maintenance:

• Observe: Keep an eye on your bee box. Look for bees entering and exiting the tubes, and observe the materials they bring back (mud, leaves, pollen). This will help you understand which bees have moved in and their activity patterns.
• Avoid Disturbing: Avoid disturbing the bee box when it’s active. If the tubes are sealed, do not open them. Observe bees from a distance and allow them to perform their natural process.
• Cleaning: Clean the bee box annually, preferably in late fall or winter when the bees are dormant. Remove and clean the nesting tubes by scraping out debris. If you used removable inserts, remove them and discard the old paper tubes. Clean the box with soapy water and let it dry before reassembling. This practice helps to prevent the build-up of pests and parasites.
• Monitoring Parasites: Watch out for signs of parasites, such as tiny mites or webbing. If these appear, research natural treatment options and clean the nesting sites more frequently.
• Replacement: Replace any damaged or decayed parts of the bee box. Wooden components may deteriorate over time, so replacing worn elements is essential for long-term usage.

Troubleshooting: Why Are Bees Not Moving In?

If you’ve followed these steps and still haven’t attracted any bees, don’t worry! Here are some potential reasons and solutions:

• Incorrect Tube Size: Double-check that your tubes are the right size for your target bee species. Having a variety of sizes will maximize the chances of attracting bees.
• Poor Location: Consider adjusting the position of your bee box. It may not be getting enough sun or may be too exposed to wind and rain. Relocate the box to a place that best meets the requirements.
• Lack of Food: Ensure your garden is rich in nectar and pollen-rich plants. Introduce more bee-friendly plants to encourage more bee traffic.
• Competition: If you have other bee boxes nearby, the bee population may already be occupied. Consider spacing out the bee boxes or starting with a smaller one.
• Time of Year: Bee activity is seasonal. Bees may not be nesting during certain periods. Patience is key.
• Pesticide Exposure: Check with your neighbours if they use any pesticides. If pesticide exposure is the issue, speak with your neighbours about adopting more natural pest control alternatives.
