Title: Defense against poison ivy from The Woodlands TX
Answered by: Barbara Medford

QUESTION:

Hi and thank you in advance for your help. My husband is allergic to Poison Ivy, Oak, Sumac, or something in our yard. We need someone who is very knowledgeable to come and identify any poisonous plants etc. in our yard. We live in The Woodlands, Texas. Would you please recommend someone who we could contact to help us.

ANSWER:

We are sorry, we have no contacts on the sort of professionals you are looking for. Even if we searched the Internet for someone who does that kind of work, we could hardly recommend a business with whom we had no experience. You are not alone in this problem. Here are two previous answers on how to protect yourself and how (hopefully) to get rid of the stuff.

Here are the three plants you mentioned. You will note they all belong to the genus Toxicodendron:

Toxicodendron radicans (Eastern poison ivy) (also sometimes referred to as "poison oak"

Toxicodendron radicans (Eastern poison ivy)

Toxicodendron vernix (Poison sumac)
