Wood – is there an oil-based sealant to discourage carpenter bees from eating cedar siding and trim

oil-based-paintsealantwood

I have read that only a paint or varnish layer will do the trick, but I'm wondering if there's any oil-based penetrating sealant for cedar that has some ingredient carpenter bees find noxious, so I can discourage them from chewing up my siding and trim. Last summer was really bad, and today they're back.

They're are insecticides that will keep these flying drill bits from nesting in your eaves. The ones I know of need to be applied by a pro but seem to be good for multiple years.
