Attract friendly native mason bees. Mason bees, also called orchard bees, are native to North America and live in wooded areas and even around homes and other populated areas. Mason Bees are pollination helpers that will increase production in fruit trees and berry plants, each doing the job of about 100 honeybees. It is not in their nature to chase or sting unless aggressively provoked. After nesting, Mason Bees emerge from these tubes as the first blossoms appear in spring – first the males, followed by a greater number of females. Each female lays 6 to 7 eggs per 6-inch tube. Swap out used tubes with fresh replacement tubes, and increase your bee population by gradually adding more tubes. Bees not included.

  • Replacement Tubes measure approximately 6" long x 5/16" in diameter.
  • Kit measures approximately 6.25" long x 3.25" in diameter.

How many tubes come with the Nest Kit? When do the tubes need to be replaced? I live in Southeast Missouri....when do I need to put a nest out for the Bees?
blondee1 on Feb 24, 2016
BEST ANSWER: The Mason Bee Nest Kit includes approximately 65-72 tubes made of durable cardboard. Depending on the activity of your native Mason bee population (which can increase in size each year), you can replace the used tubes ??? once they're empty ??? in early spring. If the tubes still seem to be in good shape, Mason bees may reuse them to lay eggs, but plan to replace with new tubes as the old ones become weather-worn. The best time to place your Mason Bee Nests is when things are in bloom there, since the bees will be active and seeking shelter. Make sure you chose a place that won't get direct precipitation (rain/snow) but will still get nice morning sun to help rouse these busy beneficials!
How do I mount or place this mason bees nest? What might I use to secure it?
Sean T on Apr 9, 2016
BEST ANSWER: Somewhere that gets morning sun but provides some protection from rain. Since the bees aren't aggressive, you can keep it close to your garden and at eye height. You are supposed to store it over the winter and clean out the holes to prevent mites. I used a wire through the attached string and wired it to a branch in a bush alongside my garden.
Where do get the bees?
D N on Feb 20, 2016
BEST ANSWER: Mason bees are native to North America ??? mostly living in wooded areas but even in more populated places as well. They're likely already in your area. The mason bee nests simply provide a home specifically for these hard-working beneficial insects.

Nicely constructed
This item is very nicely constructed. We have already hung it up. So far no residents have moved in because we got it up a bit late for the egg laying season. Maybe next year! We love our bees. in addition to honeybees, we also have bumblebees, mason bees and this year we met our first leaf cutting bee. Great little item for giving the solitary bee a nice safe place to lay eggs. I also bought the replacement tubes. They, too, are nice and sturdy.

colony expansion made easy
installed my 2 new tubes and filled another tube with the re-fills ordered.
have an established colony nest, the girls started working the new tubes immediately.
they now have 'new clean' tubes to work, that I can distribute this fall to others who may want them. my old blocks are never certain that they have emptied and been refilled with new larvae. with these tubes I know which are fresh.

Too soon to tell
I've had the Mason Bee nest for 3 years but have not had any luck getting visitors. It could "bee" because I had the nest too high (8ft) so this year I placed it at 4 ft. and have the opening facing south. At the present time it's still too cold for bees to come around but I'm sure I'll see some soon.

No bees. Fell apart
Could have been my placement but I didn't get any bees. After one season the outer shell fell apart. Stark Bros refunded my money
