The Pollinator Condo How-To

Pollinator Tower is designed to be attractive housing for a variety of small native bees, beetles and other arthropods...
From the first time I saw a pollinator hotel/insect condo I began planning to build one for my garden. Although, I can't be sure which pollinators will move in, my inner budding entomologist will have a lot of fun observing and documenting what moves in and which accommodations they prefer. 

I am thrilled that you're here to see how it was constructed and I hope you build one for your garden, community center or school. Please share your designs and what you've observed with all of us in the gardening community, so that we can continue to understand and help our native bees and other pollinators.

It really is always the right time to think about pollinators!

Disclaimer: I am not a carpenter. No way, no how, so any of you with real skills can laugh your head off at my right brain construction techniques. What I figured out from doing this was that I really would love a workshop were tools are at the ready, plugs were nearby and I didn't have to spend a lot of time setting up and putting stuff away in a shed in the wayback of my garden. Having said that, let me tell you, that building my pollinator habitat was the most fun I've had in a long time.

I hope the instructions and photos are clear and that you will soon be creating your own habitat.

Construction Narrative:

After looking at dozens of marvelous and creative pollinator habitat designs I decided the simplest design was one that used stacked pallets. They were easy to come by and required absolutely no skills except stacking them so they would not topple over in the wind or snow. I got mine free from a local garden center.  But don't take just any, make sure you find ones stamped HT, that means they were heat treated not shot full of preservatives that could poison pollinators or you!





I wanted this project to be simple to make, easy to reproduce and with easily located materials,. All the materials used were purchased at a home center or recycled from found materials.
Originally, I planned on using full sized pallet, but, decided that  24"x 48" was big enough. I measured, marked the cutting lines, removed the nails that were in the way of the saw blade and then Mr I cut them. (Remember, pallets are not square, level, uniform or plumb, nor are they exactly 4'x4')
I situated the habitat in a semi-sunny spot away from the main garden, but, close enough for pollinators
I placed the first pallet section on concrete blocks that were securely set in the ground. Then, I used three bricks on each corner to hold the next pallet making sure they were steady and secure and continued this process until it looked tall enough...I only needed three.

I liked it, but it lacked a certain pizazz.  Even when I began filing the spaces with pollinator habitat materials it still looked dull. 

It really needed a roof!
roof center board is secured with shims and braces
 Rather than building a heavy frame to hold the roof, I decided to make the roof a sandwich board! A quick trip to the local home center netted 2 pieces of 1/4 inch exterior plywood (24"x40" cut to size), a bundle of cedar roof shingles and several tubes of construction adhesive. (cost under $50)
sample sandwich board roof and center board
 I hinged the roof pieces together with small door hinges and held it upright on the tower with a 20"x 24" center board of 1/2" exterior plywood. The center board is braced between two pieces of oak and then shimmed. The center board, hinges, shims and oak braces are from old projects. 

Not bad looking...

 Now, here comes the fun part~hanging the shingles!

Shingling is not difficult when you're standing on the ground and don't care if it's not perfect.  Just do an internet search and get the basics from one of the excellent videos that's available.  I especially liked this one from Fine Gardening.  
I glued the shingles to the roof and held them in place with staples while they dried.
Here's what I learned from the shingling project!

Shingling is a bottom up project!
The fat edge of the shingles are the bottoms!
When laying the shingles make sure the seams don't line up, this protects the roof from leaking.
I tried many combinations of shingles to avoid having to cut them to size. 
Construction adhesive is marvelous and easier to use than trying to nail into an attached sandwich board roof!
A few staples will hold the shingles in place so the glue can dry.
Every roof needs a ridge cap to cover the joint at the top
You will have to use a power saw again! The last layers of shingles will need to be cut off at the ridge line (see photo above to see why) or individually cut before you attach them to the roof and,
You will need to make a ridge cap to cover the gap between the two sides of the roof.
You can make a fancy over sized ridge cap that does double duty as a ridge cap and the last course of shingles.


You can do what I did, shingle all the way and ask someone comfortable with a power saw to cut off the overhang and then...
secured with clear silicon sealant
Use a small straight tree limb to make a ridge cap. It looks especially festive with a Bur Oak acorn cup to cap it off.

All that's left to do is finish filling the habitat with pollinator friendly materials.

Now go forth and have fun building your own Pollinator Condo!

PS It bears repeating, if you want pollinators in your garden, you must never, ever, ever, ever use pesticides and think about adding a bee block or condo!

MATERIALS:
2 or 3 pallets~Make sure they are stamped with HT (heat treatment not formaldehyde) each cut into two equal pieces 23"x 48" (approximately, pallets are not square, straight or uniform)  
concrete blocks, paver stones and/or brick(I had all on hand)
1 sheet 4'x4' exterior plywood cut into 2 20"x40" pieces for the roof ($13)
4 small door/cabinet hinges and wood screws    
1- 24"x20" piece of exterior plywood for the center board
2-2"x2" boards 24" long to brace the center board.
1 bundle of cedar shingles (not top grade)  ($25)
2 tubes of construction adhesive ($5)
1 tube of silicon (on hand)
caulking gun  (on hand)
one relatively straight limb for roof ridge and Bur Oak acorn cup 

TOOLS: 
Power circular saw
Screw Driver
Pruning saw
pry bar to remove nails on the pallets
Helpful husband, wife, bf, gf or partner to do the heavy cutting

POLLINATOR ATTRACTIVE MATERIALS:
Wood with different sized holes for cavity nesters
bundles of hollow or pithy stems, paper straws
stacked tree limbs with bark
leaves and straw
left over cedar shingles for critters that like to hide

  1. Looks awesome Gail! I am sure the pollinators will be happy to call it home. I am looking forward to hearing about how long it takes for them to move in and if the various pollinators are friendly sharing the same quarters.

  7. I'm glad you shared this, Gail. I have been admiring your progress on the condo for a while. I would love to build one here. Thanks for sharing your process! Just lovely.

  8. Gail, you just mentioned to me on facebook that this would be a great project for a school. I wanted to post that idea here, too, so it could live online longer than it might on a fb feed. GREAT idea. Several grades could be involved: the older ones with the more heavy/complicated elements of construction, the younger ones with the gathering and arranging of the condo units. I've seen wee condos online, for sale, but your DIY is perfect for a school.... Thanks so much for the idea, the plans and the other idea!

  24. shrub is beautiful with bright white flowers in spring and summer. Also add exquisite orange and red colors. During the spring bloom beautiful white flowers on it. Viburnum prunifolia brings beautiful features of your home or garden, because it can only add to the appeal, but may also add beautiful leaves in the fall, as well as add value to your home. Black Haw has many clusters of white flowers and is also used for many medicinal uses, such as stomach pains and burns. It has been said that many people use this bark to make a tea that can be used for premenstrual pain, bleeding and other medical problems.

  25. Gail, your condo is so impressive; I know the pollinators are going to be lining up for first dibs on the best apartments. I'm curious to see who picks the penthouse:) I must admit I've never seen one of these habitats before, but what a great idea! I know we must have a few of these materials already on hand here, and I've got just the place for one. Thanks for sharing the instructions!

  29. Soo cute!! I've seen those little mason bee houses before, but I love your big pollinator mansion! I might have to build one of those at some point!
