I have bees that have bored holes in my window trim. Are these orchard bees? I want to discourage them doing this by putting up a box and plugging the existing holes. They use the same place every year and soil my window. A new hole was put in this year. If there is a new hole every year I won't have any trim left and won't be able to see out the window.

Are there larva in the holes now? Can I make a box drilled with holes and place it nearby?

thanks for any information
