Is poison ivy worse in summer or winter?

Answer 1

Of course it does not have enough light or heat to survive,it usually dies off the first frost.

Yes this guy is correct but not really. The plant dies but the oil in the plant "Urushiol" that gives people the rash stays active on any surface, including dead plants, for up to 5 years. So even if the plant dies the urushiol oils are still there on the plant and anything else that plant touched to give you the rash. So the plant does die in the winter but not the oil in the plant stays active

Answer 2

After the poison ivy vine dies, it still has some urushiol oil, the thing that makes you itchy. It takes an incredible five years until the dead plant is safe to touch. But you don't exactly know how old the poison ivy is dead, so I wouldn't recommend touching it AT ALL.

Answer 3

The degree of worseness may be the same to the allergic individual in winter as much as in summer. The urushiol oil in poison ivy [Toxicodendron radicans] has its effects on the allergic individual regardless of the month or the season. The oil is available year round. In fact, where poison ivy is, it may leave traces of oil on fences that in turn cause allergic reactions as much as 1-1/2 years later.

Answer 4

You can if the plant is still alive and full of sap...

Answer 5

Yes, if you handle it.
