Step-by-step explanation:
When applying an insect repellent containing DEET to children, it is important to take certain precautions to ensure their safety and effectiveness of the product.
The correct precaution to take in this case is all of the above:
- Only apply the repellent to the children's clothing, as applying it directly on the skin may have potential risks.
- Apply the repellent every 2 hours for the greatest effectiveness, as the effectiveness of DEET diminishes over time.
- Make sure children close their eyes tightly as you apply repellent to their faces to avoid contact with eyes, which can be irritating.
- Do not apply repellent to the children's hands, as they may unintentionally touch their face or mouth, increasing the risk of ingesting the repellent.
