winter poison ivy shrub

Here is a small poison ivy shrub that is mostly covered by snow.

In a situation like this, it is VERY hard to spot that this poison ivy during the winter. Poison ivy shrubs don't have the reddish hairy roots that the climbing vine has. So there is nothing that screams out POISON IVY.

Here is an unusual situation: a poison ivy vine was climbing up a tree, a totally normal thing.

poison ivy wall

Drove past this garage and noticed a massive growth of poison ivy on the outside wall.

I stopped in to inform the owner that they had a potential problem out there. He was friendly and said he know about it. 

But see those thick, hairy vines? Nothing else has quite that look.

We went out did what you should think twice about: cutting a poison ivy vine with a chain saw.

Cutting into the bark releases gobs of the sap that contains the urushiol oil that can land you in the ER.

Maria's Nightmare Poison Ivy Rash

This is a case where a picture is not worth a thousands words. You need to hear Maria's story before you can appreciate just how bad her experience with poison ivy was, and understand how very bad it can be. In her own words.

Here at the poison ivy site we have seen our delivery times rise with absurdly long delays. Recently a simple Priority Mail package took from July 1st to July 31st to reach a customer in the midwest. We spent many hours and paid extra fees to track the package.

staghorn sumac

We are always surprised by how many visitors to our website are looking for information about poison sumac, not poison ivy and oak.

It turns out that poison sumac is extremely hard to find in most areas: I met a trained botanist with decades in New England who had never seen it!
