An invasive weed from South America, Brazilian pepper can cause serious problems in your garden both with its quick growth habit and its tendency to cause a serious rash. Its leaves and bark contain a toxic oil known as urushiol, shared also by poison oak (Toxicodendron diversilobum), poison ivy (Toxicodendron radicans) and poison sumac (Toxicodendron vernix). Because these plants are invasive weeds and not desirable garden plants, they do not have designated U.S. Department of Agriculture plant hardiness zone ranges, but Brazilian pepper generally grows in warm areas.
When burned, the Brazilian pepper’s toxic compound can become airborne and very dangerous. When it comes into contact with skin, the smoke can cause a rash. Even more dangerous, inhalation of the smoke can cause severe irritation or burning of the mouth, throat and lungs, and may even be fatal if enough is taken in. Smoke is poisonous to humans and animals alike, so you should never burn Brazilian pepper.
Although you can use chemicals if you really need to, hand removal is a much safer option, especially if you live with kids. Cut the plant down at the base, then remove the plant by the roots using a shovel or spade, and continue to remove it every year when it sprouts.
When working with Brazilian pepper, always wear full safety gear. This includes clothes covering your whole body, shoes, gloves and safety goggles. Afterwards, put your clothes and gloves in the laundry and wash in cool water to remove all of the oils. Disinfect your tools while still wearing gloves so as to avoid later touching oil, which can stick around for a very long time. Keep children and pets away from the area to avoid contact with the Brazilian pepper. Pets can also carry the oil on their fur.
