I bought some Medina Orange Oil for flea control. Should I dilute it for a spray inside the home or use it at full strength? I am also wondering if it would be OK to use as a spray on a dog's coat? I am using this along with DE and nematodes outdoors as a comprehensive program.

Never use orange oil full strength. It will peel the paint off your wall or burn your dog's skin. Look under "library" on the main page of this website and see if Howard has a recommended dilution rate. During a google search on orange oil might help also. I have not heard of spraying an animal w/ orange oil so please research first.
