Hang this bee-r barrel in your garden and watch as the canes fill up with baby bees during the summer months. Then wait... until next spring, when the new adult bees emerge! Attracting solitary bees to the garden is not only safe but beneficial to the pollination of flowers, fruit and vegetables. Solitary bees are born pollinators! The hole sizes of this habitat are precisely designed to attract non-swarming bees like the Red Mason Bee, Leafcutter Bee and other solitary bees. These friendly bees are industrious and safe around children and pets. Mounting height between ground level and 1.5m. 17 x 16 x 18cm.
