Well, reading some of the facts on this site, it seems like poison ivy oil can last for years on just about any surface. Do you know for sure that the rash is caused by p.o.? Maybe it is still on something like a fence or handrail. How about an indoor/outdoor pet? My dog would hop the fence and run off to the park nearby. She gave me p.o. a few times! I would check this site and others for areas that the oil can still be clinging to and start with that. |
