The best method of controlling chiggers is to get rid of their habitat. Chiggers live in moist, shaded areas with dense vegetation such as thick shrubs, weeds, ground cover plants, overgrown lawn grass and densely-planted trees. These prime chigger habitats can be eliminated by maintaining a tidy yard.
Mowing the lawn, weeding, and trimming or pruning trees and shrubs regularly expose the soil to sunlight and wind. This raises the temperature and lowers the humidity of the soil, making the area less habitable by chiggers. Removing accumulated leaf litter and brush piles, on the other hand, eliminates prime breeding grounds for chiggers. Pesticides should only be used in areas where chiggers have become a chronic problem.
