Bamboo canes and nesting blocks for solitary bees

In the right hands, bamboo canes have been successfully used for years to attract solitary bees to nest inside. The key words here are ‘in the right hands’. People who successfully use them know what bees need, how to adapt the canes for the bee’s requirements, how to safely open the canes and manage the contents. This can take time and experience.

Go to any garden centre or pet store and look along the wildlife section. You will be amazed as to what is on offer for our wild bees.

Non-suitable materials inside solitary bee nest boxes

Straw, pine cones, wood fibres, dried wood wool, hay, wood chips and bark are great habitats for insects, e.g. earwigs which will predate on solitary bee eggs and eat pollen. Such materials have no place in a box made to encourage solitary bees.  Non-bee insects or bug boxes yes, solitary bee nest boxes? Never!

 

Bamboo tubes useless for solitary bees in this conditionEntrances blocked by sharp transverse fibres that will damage bee wings

Some nodes completely blocking the entrance

Some canes shortened by nodes

Some are complete wind tunnels. Bees would not waste time sealing the ends of these

The short length of usable ones would encourage more males, fewer females

Small node entrance, with a vast expanse of the bamboo cane on the other side, make it useless.
