How To Build A Bumble Bee Nest
Jan 2Bumble Bees are responsible for pollinating our tomatoes, so why not give them a helping hand by providing a nice office in the backyard? There are two compartments inside this design, divided by a piece of wood with a hole in it, so the bees are able to crawl from one room to the other.

Start by cutting 9 pieces of wood. The long ones are 41 cm (16″) and the short ones are 15 cm (6″). I have used some spare wood with the dimensions 9.5 cm x 2 cm (3.7″ x 0.8″), but something else can be used instead:

Drill three holes in the middle of the short pieces: Entrance, middle corridor and peek hole. The piece with the peek hole I made with a 10 mm (0.39″) drill:


The holes for the entrance and the middle corridor needs to be 20 mm (0.79″) in diameter:

I didn’t have a drill this big so I used a file to make the holes bigger:

A Dremel can also be used if you’re impatient


I found that if I drilled first with a 2 mm (0.079″) drill it was much easier to get the screws in when assembling the nest:

You can use an electric drill for the screws if you want to work faster:

Left and right side assembled:

The three walls are fastened to the left side. The front compartment is 15 cm x 15 cm (6″ x 6″). This is where the bees can set up a defence against the outer world. The nesting compartment in the back is 20 cm x 15 cm (7.9″ x 6″). The walls are 2 cm (0.79″) thick:

I put in two pieces of cardboard as floor, which should make it easier to clean after the season, but I’m not sure, if parasite eggs will survive in the joints of the box, so that I’ll have to scrap the whole box and build a new one next year. I have to do more research on this.

Moss has been put in the larger nesting compartment:

The two pieces to put on top as roof have been glued together to keep the rain from dropping down from the joint:

The finished nesting box is lifted from the ground to keep it dry:

Then we’ll just have to wait for a queen to find the nest in the spring. The plastic bag of peat moss you see on the left was the nest of last year, so there should be a chance that a queen will stop by and move in.

Did a queen ever find your nest?

Well, not exactly. There are bees all over my lawn and it looks like they’re searching for a place to build a nest in the ground. I see maybe two or three each day behaving like this. I’ve watched the nest I built but it doesn’t seem like there’s any activity
Maybe I get too close with the lawn mower, I don’t know… -

Cool, I want to try this

@star: It’s a good idea to build some kind of roof that covers the entire nest, since the rain is a bit hard on the wood if it’s is raw and untreated like the type I used.

Try painting a yellow and purple pattern near the entrance hole

@Metz: You mean like a flower? I think that might work, thanks! I’ll give it a try.

Your box looks sturdy and good, but I think bumblebees might not realize they can nest there.
One of the bumblebees’ favorite nesting spots is in old mouse nests, so you could try to a few things to imitate those:
1. Lower the box, so the entrance is closer to the grounds. Most bumblebee species prefer entrances close to the ground.
2. Attach a footlong garden hose length to the entrance, bury the mid-section and let the end peek out of the dirt. This makes it resemble a mouse nest more.
3. Claw away plants near the hose entrance, mice do this around their nest entrances.
4. If you can find some mouse droppings, scatter them around the entrance.
5. You should make at least two or three ventilation holes (cover them with plastic netting to keep ants out), especially if your box receives any amount of sun during a day. Bumblebees need a particular temperature range, and with only one hole it might be hard for them to maintain this.I made my own bumblebee nest from an old flower pot a little while ago, check it out if you’re interested:
