Large black and yellow bees drill perfect holes in anything wood and apparently nest in there.
It sounds like you may Carpenter Bees. Please refer to our article on How to Get Rid of Carpenter Bees. We have also put together a carpenter bee kit that includes the dust and dust applicator to apply into the bored holes and the residual spray to spray along the outside of the holes. Please let us know if yu have any other questions.
