Saveing Bee one box at a time

I put together these boxes to house local bees I save from the community. Instead of killing them with pesticides they are saved to pollinate our food.
I have a range of different boxes I buy and customize with latches so the bee boxes stay together and don't shift. As the bees fill the boxes with baby bees and honey I stack them and add latches. I have to spray the latches with wd-40 so they open and close with ease.
I have saved thousands of bees and will continue to do so so my project will be on going.
