Use pesticides safely!

Wear protective clothing and safety devices as recommended on the label. Bathe or shower after each use.
Read the pesticide label—even if you’ve used the pesticide before. Follow closely the instructions on the label (and any other directions you have).
Be cautious when you apply pesticides. Know your legal responsibility as a pesticide applicator. You may be liable for injury or damage resulting from pesticide use.
