Each year, it is best to provide fresh nesting tubes for the mason bees. Ideally, replace “used” tubes as soon as they’re empty in early Spring. Newly hatched females prefer to use new empty tubes, but they’ll re-use the old ones if they must. 50 tubes included each measuring 6″ long x 5/16″ in diameter. Mason Bee Nest Kit shown in the photo is not included.
