The oil can also be transmitted on pet fur and in the smoke of burning poison ivy. YOU CAN USE various products such as MultiShield applied prior to anticipated exposure or Tecnu Skin Cleanser to cleanse exposed skin. However, the best way to avoid the irritating rash is being able to identify poison ivy. The white, waxy berries are a popular food for songbirds during fall migration and in winter when other foods are scarce. Robins, catbirds and grosbeaks especially like the berries.
Many birds feed on insects hiding in the tangled vines.
Another common misconception is the belief that poison sumac or shumac grows in Missouri. This shrub or small tree resembles smooth sumac but has never been found in the state. Poison ivy should be accurately identified before you attempt any control measures. Spraying is recommended over burning because poison ivy oil vaporizes when hot, carries in smoke and can cause a severe rash. When using this or any herbicide, always read and follow label directions carefully.
