The most important step in avoiding an earwig infestation is minimizing moisture levels as much as possible. Some things that can be done to achieve this are ensuring effective drainage and gutter systems and trimming trees and shrubs that cause shady, damp areas. A 6 to 12 inch wide dry zone should be created around the foundation that is devoid of mulch, dead leaves, and other moist, organic material. Decorative stones, firewood piles, landscaping timber, and logs should be moved away from the foundation, and any organic debris piles should be removed from the property. Dehumidifiers should be implemented in damp areas like basements and crawlspaces. Set irrigation systems to water in the morning so the landscape can dry throughout the day. Any possible entry points, such as cracks in the foundation or gaps around windows and doors, should be fixed or sealed. Consider changing the lightbulbs in outdoor light fixtures to yellow bulbs, as yellow light is less attractive to insects than white light. When home and business owners try to exterminate an Earwig infestation on their own, the earwigs usually return. Seeking professional help is not uncommon for this problem.
