BEEKEEPING IN THE NORTHEAST - An account of my beekeeping, not a treatise of expertise, but for friends & family who wish to keep bees vicariously through me, and for the occasional apiarist passer-by.

What paint to use for a beehive

What Kind Of Paint Should You Use For A Beehive?
Some years ago I came across a wonderful article I can no longer find about how to paint a hive. The paint recommended there was a winner. My hives from six years ago still look freshly painted to me. Dries fast, and can use at low temps. I've been very pleased. Since then I've found out a few things helpful to beekeepers about painting their hives. I'll try and be thorough here with examples and links.

What to use:  Exterior Paint, Latex. The photos above are with a weatherproofing stain, VOC less than 100. Drying time well over a few weeks before installing bees.
In our northern climate I make sure I can use it in cold weather. VOC less than 50 - (Fumes & Smells) links go to Wikipedia & Minnesota Dept of Health sites, respectively. Another article is at the Natural Resource Defense Council website.
~ This VOC is right on the can of paint ~ and stands for Volatile organic compounds that result in chemical molecules released into the air that may be harmful to humans and animals. Most articles you find are about indoor paints and less than 50 is considered acceptable by our local paint dealer. VOC of ZERO does exist. I recommend checking out Sherwin-Williams. At any rate, my Sherwin-Williams Super Paint does not smell to me and I SMELL EVERYTHING! (Much to my husband's dismay.) 
~ UV - Check the color numbers! LRV ~  means Light Reflective Value and is right on the color sample card, or should be.
Why do you need to care? Over-heating, cooling, and what bees can see:
Bees see only ultra-violet colors. Colors look different and bees are attracted to our Purple, Violet, then Blue in that order. Red doesn't work for them. White looks bluish-green to them.  
A row of look alike hives can result in drifting of bees from their hive to another. Painting them different colors can help. Heat and Cold: Painting hives black with an LRV of Zero, can cause an over-heated hive. The LRV for dark green, for instance, is 9 so I chose it for my winter wind block along the sides and back of the hive. (See this at AthenasBees). The lower the number the hotter the color. Pastels may be more like LRV 74.

What does this mean? Colors look different and they are attracted to our Purple, Violet, then Blue in that order. Red doesn't work for them. White looks bluish-green to them.
How To Paint:
  • That's basically it.
The hive parts that touch each other must be paint free. Paint only the outside surfaces for weather proofing the wood. The bees will propolis the insides. The landing board may be completely painted as it does not touch the bees nor need to be removed during an inspection.

Thank you for your blog. It is here, I found information on what colors bees prefer.

I attempted to keep bees back in 2011 and 2012. But both years, I was unsuccessful in getting the bees through the Winter. The last Winter was 2013, when so many beekeepers lost many of their hives. I elected to quit at that point. But this year, I have a nuc on order, and will take delivery in late April or early May. Your information is very useful. I have saved your blog on my favorites.
