Poison oak removal at a house in Marin last week.￼ Urushiol oils are the active allergins in this native shrub, and those found inside roots and stems are 50-100x more potent than oils on the surface. ￼These oils are mostly invisible but stain black on fabric after cutting.
￼The stalk on this particular vine was about as big around as my arm, a rope and chainsaw were used to pull it down from a bay laurel tree. I uprooted it as well.
If not for immunity to this plant, a job like this would almost surely put me in the hospital. Unfortunately my helper who￼ didn’t even touch it directly got a pretty solid rash.
As for the scorpion photo, we found them at a jobsite in Marin the day before.
