To avoid chigger bites, wear long sleeves, pants, and tightly woven clothing when in infested areas, such as tall grass or brush. Use insect repellent containing DEET or permethrin on your skin and clothing. After outdoor activities, shower and wash your clothes promptly to remove any chiggers that may have come into contact with you. Additionally, maintaining a well-groomed yard can help reduce chigger populations.
The severity of a chigger bite can vary from person to person. The actual bites themselves look like hives or small pimples, but you can also get a rash associated with the chigger bites. If the area they bit was exposed to the sun, you may get an itchy rash as well. One very good way to tell if what you have is chigger bites is by their location. Chiggers congregate in areas where clothing meets the skin, such as waistbands, ankles, and underwear lines.
