Box Testing – Temperature

Poly Box and Hoop Pine Box

Box temperature testing in progress…

The below information may be all over the place. It’s still in progress.


Full Sun Tests

Empty boxes placed in full sun for testing. I would not recommend placing boxes with singless bee colonies in full sun!


25mm Poly Composite and 25mm Hoop Pine

Temp test: 10/01/2021 – 10am to 11am – Full Sun

  • Boxes in full sun for 1 hour
  • 30 degrees in the shade at 11am
  • 28.9 in the Poly box at 11am
  • 28.5 in the Hoop Pine box at 11am
  • 0.4 degree difference between boxes

Temp test: 12/01/2021 – 11:30am to 3:30pm

  • Boxes in full sun for 4 hours
  • 32 degrees in the shade at 3.30pm
  • 33.8 degrees in Poly Box at 3.30pm
  • 32.9 degrees in White Hoop Pine box at 3.30pm
  • 0.9 degree difference between boxes

Temp test: – 14/01/2021 – 8am to 1pm – Full Sun

  • Boxes in full sun for 5 hours
  • 32.5 degrees in the shade at 1pm
  • 33 degrees in Poly box at 1pm
  • 32 degrees in Hoop Pine Box at 1pm
  • 1 degree difference between boxes

I noticed the surface of the Poly box in full sun is warmer to touch than the surface of the Hoop Pine box. I would assume this heat would transfer in to the box. It might help if the surface was rough, less dense or painted white. Future test?


33mm and 25mm Hoop Pine Box

Temp test: 15/01/2021 8am – 1pm – Full Sun

  • Boxes in full sun for 5 hours
  • 32.5 degrees in the shade at 1pm
  • 32.9 degrees in 25mm White Paint Hoop Pine at 1pm
  • 33.2 degrees in 33mm Yellow Paint Hoop Pine at 1pm
  • 0.8 degree difference between boxes
  • The surface of the yellow box was warmer to touch

34mm Cypress and 25mm Hoop Pine

Temp test: 16/01/2021 8am – 1pm – Full Sun

  • Boxes in full sun for 5 hours
  • 35 degrees in the shade at 1pm
  • 36.9 degrees in Cypress Box at 1pm
  • 33.9 degrees in Hoop Pine Box at 1pm
  • 3 degree difference between boxes
  • Cypress box surface was hot to touch so possibly gets hotter because of colour and density?

more testing to come…
