It all started with the actual pieces of the house being created with some precut pieces of baseboards. I figured they would have plenty of length and they were just sitting around. From that, I created a compartment "shell" to house the layers of blocks. I used a table router to "groove" the baseboards. Generally, you want to create holes or grooves that are about 5/16" and about six inches deep. I created this setup like others out there so I could harvest the "cocoons" at the end of the warm season to safely keep them in the fridge until the next release. With Louisiana's freakish weather, I don't want to leave it up to our roller coaster weather swings to unecessarily confuse the bees until they have a proper habitat, food and water to do their best. Also, this setup allows for cleaning of the grooves after each season to remove any mites or other things that harm or inhibit the bees.
