All earwigs feel at home in decaying vegetation and moist soil, which is why it's common to see earwigs running out of leaves and decaying debris. Since earwigs love to live in moist conditions, homeowners should make sure there are minimal moisture conditions in their home. It's important to minimize moisture conditions in both the inside and outside of a home. Overwatering a lawn can create ideal conditions for earwigs. It's almost always best to contact a pest control expert. Earwig infestations can become quite large.
