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.

To provide the bees a safe place to lay eggs so I don't accidentally destroy a nest site in old flower stalks when I mow an area of my field.

Need to invite more pollinators into my orchard.
Tana R on Nov 27, 2020
Some years we don't have any pollinators and thus no fruit ,etc. here on the mountain.
Bears clean out the local honeybee guys so I will give this a try.

I'm looking for natural ways to improve yields in our small yard and help restore bee populations without having regular hives to manage. This seems like a great fit.

Need to encourage more bees
Debra N on Mar 3, 2019
I have about 2 doz. fruit trees and numerous flowering plants and shrubs, so I need pollinators. There are fewer and fewer honeybees in our area, so I want to encourage native bees.

To increase pollination for garden and orchard
CHRISTOPHER H on Mar 4, 2017
These nests really work! I've been using them for years. You wont believe the activity once you set them out! When winter comes I just put them in my shed and bring them back out in April. Every year I have tons of Mason Bees pollinating my entire backyard, its awesome!!!
BLAIR R on Feb 27, 2017
Mason bees are pollinators. Plus, giving them a home keeps them from drilling into the facings around my garage

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!
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.
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: We used a wooden house type box and mounted it on the corner of a shed that is out of the way. I haven't checked it yet so don't know if any bees have started using it.
Could I spray waterproof on the outside tube?
ctp2236 on May 10, 2017
BEST ANSWER: The outside pot is earth-friendly and biodegradable, but it's made of compressed straw, rice husk and bamboo, so it resists water as-is. I don't know if any waterproofing spray would deter the bees from using the product, so for that reason I wouldn't recommend it.
We live in SE Colorado - prairie. We have a garden with wind protection. Will mason bees be a good fit for us? Our garden includes apple trees, currants, gooseberries, and various herbs and vegetables in the summer.
Londa P on Nov 30, 2020
BEST ANSWER: Mason bees love fruit trees and shrubs. They also pollinate other trees. Give them somewhere to nest and increase population.
Diameter of tubes?
Joanie W on Mar 31, 2020
BEST ANSWER: tubes are 1/4 inch diameter, however, I have had them colonize in larger and smaller openings
Diameter of holes?
Joanie W on Mar 31, 2020
BEST ANSWER: mason bees are on the larger side of bees but they are smaller then honey bees. this is not natural reeds so they are all the same size. if you have berry bees then they will not like this but will use them in a pinch. mason bees are orchard bees and to make them stay they will need some very fine grain clay so they can fill the tube up after they lay eggs. bees are not included, go to masonbeesforsell they are good guys to buy from
Do they pollinate your garden?
Bonnie L on Feb 4, 2021
BEST ANSWER: Blue mason bees act like other bees in that they buzz from flower to flower collecting pollen for themselves and their young. As they go about their business, they are happily pollinating your garden veggies, fruit, and flowers.
Will mason bees reuse nesting tubes in following years?
Tana R on Nov 27, 2020
BEST ANSWER: Discard the old tubes after last year's bees have emerged to prevent insects and diseases.

Does this include only the small inner tubes, or also the housing (larger outside tube)?
Dan M. on Nov 18, 2019

Can mason bees survive freezing temperatures?
DrDavecfn on May 17, 2019
BEST ANSWER: I always put the nests in my shed during the winter and I never have had a problem in the spring then. I always have tons of mason bees.
Can I add more wood to the roof of my mason bee house so rain does not get in? All the mason bee houses have overhangs about an inch. If I make the overhang wider, will that affect the bees or hive in any way? I'm new to this, so thank you.
newtomasonbees on Mar 10, 2018
BEST ANSWER: I installed mine under the eaves of a shed and it is being used for the second season. The roof overhang does not seem to negatively affect the bees use of it. I realize this does not directly address your question.
We have wild bees here in Arizona but I don't know what kind. Will the Masons cohabitate with others bee species?
AZTom on Mar 5, 2017
BEST ANSWER: Mason bees are naturally located in Arizona as well as across the United States. I'm not sure what is meant by cohabitate, but this nest is designed specifically to suit the nesting nature of mason bees. Hive-dwelling honeybees won't use it, for example.

"My Nests Are Full!"
These nests work great, clean and change out tubes! Easier then trying to clean out holes drilled in wood blocks! I purchased two nests put them out beginning of April and both are full! They don't come with anything to hold/nail them up so I had to build a little 5inch by 9inch untreated cedar box to hold them and protect them. I have it hung 4ft off the ground facing west. I couldn't believe how fast they were full! I grow peaches and have been using mason bees for 4 years now to help with pollination! Don't give up, the bees will find your nest and then every year after you will have tons of pollinators!

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.

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.

bees love it!
At first it was quiet here, then I noticed signs of some tubes being used, now it's a party! I've seen so many bees here already this season. Great they know they're welcome here.

New Bee Culture
Can hardly wait to get this out to our backyard orchard. Each year we have had fewer and fewer honey bees to our fruit trees. So I am hoping these will make a difference. Product looks well made and it is a good size also.

All 24 Mason Bee nests have found new garden homes!
What a treat to offer 24 bee homes for pollinating creatures which were used as centerpieces at an evening lecture given by two PhD women speakers. Their subjects were marvelously in-line with their lectures.

Mason Bees Nest
I am not especially impressed with this product. Two years and not a single bee. Might be they are just not around.
