I have my hives on 4-way pallets with strips, which create the entrance. Two hives face the opposite direction of the other two. During the rainy season, a lot of water gathers at the bottom of some hives.
I guess, the rain gets mostly through the entrance, if the pallet is inclined or through other cracks. Moisture stimulates the mold growth and is bad for bees. I had a case when bees bearably were able to get out through the entrance, because water was so high.
I made some holes on bottom boards (pallets), but they got clogged with dirt.
Now, I want to reconstruct the hives to keep the water away. Any suggestions will be appreciated. Thank you.
