To kill out poison ivy try planting virginia creeper right with it- (don't confuse it with poison sumac-)
It has replaced the noxious weed on the trees in my front yard.
A trip to the hospital/drs office- was a regular thing for me too- finally figured out I was getting it off the dog.
Try dusting with DE before traipsing out around it-
I wonder if an application of DE to the plant would absorb the urisol enough to dispose of it..?? I could try but... no
Always remember to wear long sleeves, long pants, gloves. When finished, turn them insideout when you take them off. - put them into the washer and head for the shower- I spray down with a strong bleach solution then do an all over shampoo- without using a cloth, brush, loofa etc. I've had outbreaks around scrapes, cuts etc. just a good foamy lather and rinse off then powder-
The naturapathic pills do work (for me ) as do cornstarch baths once you get it.
As for the removal- goats are tops- but don't leave them around your blueberry bushes too long. I have found they will eat anything especially if the experts say they won't.
DO NOT BURN !
Best o' luck with your PI - hope you can find a solution that will not negatively impact your plants and soil.
