Insect repellents are substances designed to deter insects from landing on the skin or clothing. They are commonly used to protect against bites from mosquitoes, ticks, and other pests that can transmit diseases. Repellents can come in various forms, including sprays, lotions, and wipes, and often contain active ingredients like DEET, Picaridin, or Oil of Lemon Eucalyptus. When applying insect repellents, it's important to follow the instructions on the label for safe and effective use. Some products are suitable for children, while others may not be recommended for sensitive skin. Proper application can help reduce the risk of insect-borne illnesses, making outdoor activities more enjoyable.
