Each tube is 6" long x 5/16" diameter.
New thicker tubes help prevent parasitic wasps from laying their eggs!
Bees are NOT included.
Provide additional fresh nesting tubes each year, ideally replacing "used" tubes as soon as they're empty in early Spring. Newly hatched females prefer to use new empty tubes-but then they'll re-use the old ones.
If you put the nest kits outside in the very early spring (when the fruit trees are in bloom) the bees will come!

This photo shows our colony of Mason Bees. We started out with one empty nest kit five years ago and now we have a colony of over 4000 bees!

Mason Bee replacement tubes
For the last 2 years I've really enjoyed my mason bees. After the first year, I puchased the 3 solid houses and the protective wood housing. Last year most of the tubes were filled. So I just bought 100 replacement tubes since I hear the bees like new nests and that keeps down the mite population.

Mason Bee Tubes.
Order took awhile to receive but is what I ordered. I like these tubes better than the old style one I had before because they seem to be make of a sturdier material.

REPLACEMENT MASON BEE HOUSE TUBES (100 TUBES)
I'd like to give a 5, but I've just received them and of course they haven't gone through the real life trial in my garden yet ;) But they are very nice - uniform size, very clean, well packaged and arrived in perfect condition. I will update after I see how my bees like them!

tubes need to be re-designed
Unfortunately these tubes are totally sealed on one end. Not good for bee keeping. I have lboriously cut the sealed ends off all of the tubes.REPLY FROM KINSMAN COMPANY: Our tubes are hollow and open on both ends.
