poison ivy (or oak) is caused by exposure to the olioresin (oil) of the plant. it does not come back in the same place two months later unless you were re-exposed to the oil again. the oil can remain stable on an object for years so you don't have to come in contact with plant. just an object that still has the oil on it. please be sure you actually have poison ivy. many skin eruptions can mimic this allergic disorder and some can even show up in the same place (like eczema shingles etc. ).
