Repellents are designed for use on exposed skin and sometimes clothing depending on the type of formulation and labeled instructions.
Repellents do not kill insects and ticks—they simply repel them, so do not spray them in the air, on insects, window screens, or other items. Instead, spray a small amount on exposed skin and smooth it on evenly.
Before applying repellent, be sure to read the label and follow the directions. The label contains important information on the product formulation and how to use it properly.
