I know this is strange, but I was thinking about putting our nuc boxes on top off a roofing shingle to keep the entrances free of grass. We are going to start about 100 nucs in the spring, and they are a two hour drive from the house.(which limits access and time spent in the beeyard) The grass gets pretty tall pretty quickly in the spring.

I am worried about odors or chemicals coming of the shingles and bother the bees.

Anyone have any ideas about this or other solutions?
