Cedar has long been known to control molds,and eradicate insects,vermin.I wish I had a good source of cedar here in Florida for furniture,trellis projects,staking etc.I can get it but way too much for my pocketbook.I know there are some cedar oils used for pest control.Here is some background info.

According to this plant scientist, alleopathy of cedar sp. is a myth:

"Concern: Woody mulches, such as cedar, leach allelopathic chemicals that
kill other plants.

Evidence: Many plant materials contain allelopathic chemicals, which can prevent seeds from germinating or kill young seedlings. Most compounds have no effect upon established plants. Only a few woody materials have been found to contain allelopathic chemicals
(e.g. Juglans nigra, black walnut). Cedars (Thuja spp.) have not been found to have
this ability."

From "Wood Chip Mulch: Boon or Bane?" on the Horticultural Myths website hosted by Washington State University.

I put this in my favorites to use to quell some of those old wives tales that keep popping up all the time.
