Take a Hot Shower
As soon as you realize that you are bitten by a chigger, take a bath with hot water. Use a mild soap. This will reduce the effect of the chigger bite.
Make a paste of baking soda and water, and apply it to the affected area. This is an effective chigger bites treatment.
Use a Dryer
Hold a dryer 5cm away from the bite and blow it dry for about 2 minutes. This will relieve the itchiness caused due to the chigger bite.
After washing the affected area with soap and water, soak a cotton ball in some Listerine mouthwash and apply it to the chigger rash.
