There are different types of cedar wood,spainish cedar which has a musty odor,aromatic cedar (which is used in cedar chest) has a pungent odor,western red cedar has the lightest smell.
The only one that may have an affect on the bees would be the aromatic cedar as it does not lose it's odor with age as the others do,that's why we use them for cedar chest.
I would be interested in know what affect it would have on the wax moths though.
I have hives made out of mahogany,cypress,pine,and spainish cedar.Some day want to build an observation hive.
New to beekeeping but years with wood.
