Earwig Control in Basements: Strategies for Eliminating Basement Infestations


Basements are common areas where earwigs seek refuge due to the dark and damp conditions they provide. Dealing with an earwig infestation in your basement can be frustrating, but with the right strategies, you can eliminate these pests and prevent future infestations. In this article, we will discuss effective strategies for controlling and eliminating earwig infestations in basements. From identifying entry points to implementing preventive measures, we will explore various techniques that will help you reclaim your basement and maintain a pest-free environment.

Identify Entry Points:

The first step in controlling earwig infestations in basements is to identify their entry points. Inspect the exterior of your home for any cracks, gaps, or openings that may serve as entryways for earwigs. Pay particular attention to areas where utility lines enter your home, foundation cracks, windows, and doors. Seal these entry points using caulk, weatherstripping, or other appropriate sealants to prevent earwigs from entering your basement.

Improve Ventilation:

Basements are prone to excess moisture and poor ventilation, which are attractive conditions for earwigs. Improving ventilation can help discourage earwigs from infesting your basement. Ensure that your basement has proper ventilation by opening windows, using exhaust fans, or installing a dehumidifier. These measures will help reduce moisture levels, create a less favorable environment for earwigs, and make your basement less inviting to these pests.

Reduce Moisture:

Earwigs are attracted to damp environments, so reducing moisture in your basement is crucial for controlling their populations. Fix any plumbing leaks promptly to eliminate a potential water source for earwigs. Ensure proper drainage around your home to prevent water accumulation near the foundation, as this can contribute to basement dampness. Consider using a basement waterproofing system or applying a moisture-resistant sealant to basement walls and floors. By addressing moisture issues, you create an inhospitable environment for earwigs and reduce their presence in your basement.

Remove Clutter and Debris:

Clutter and debris provide hiding places for earwigs, so it’s important to keep your basement clean and organized. Remove any clutter, boxes, or unused items that may accumulate in your basement. Pay attention to stored paper products, cardboard boxes, and fabric materials, as these can attract earwigs. Seal and store items in plastic bins or containers with tight-fitting lids to prevent infestations. Regularly clean your basement, sweeping or vacuuming to eliminate potential hiding spots for earwigs.

Seal Cracks and Crevices

Earwigs can hide in small cracks and crevices in your basement walls, floors, and foundation. Inspect your basement for any visible cracks or openings and seal them using an appropriate sealant or epoxy filler. Pay attention to gaps around utility lines, pipes, and electrical outlets. By sealing these cracks and crevices, you eliminate potential hiding places for earwigs and prevent them from accessing your basement.

Use Traps and Baits:

Trapping and baiting can be effective methods for controlling earwigs in basements. Consider the following options:

Moistened newspaper traps: Roll up damp newspaper and place it in areas where earwigs are commonly seen. Earwigs are attracted to the moist environment and will seek shelter within the newspaper rolls. In the morning, collect and dispose of the trapped earwigs.
Beer traps: Bury small containers, such as shallow dishes or cans, in the ground near earwig activity areas. Fill the containers with beer, which attracts earwigs. They will crawl into the containers and drown. Check and empty the traps regularly.
Professional Pest Control:

If the infestation persists or becomes unmanageable, it may be necessary to seek professional pest control services. Pest control experts have the knowledge, experience, and resources to effectively eliminate earwigs in your basement. They can assess the extent of the infestation, determine the most appropriate control methods, and provide long-term solutions to prevent future infestations.


Controlling and eliminating earwig infestations in basements requires a combination of preventive measures and active management. By identifying entry points, improving ventilation, reducing moisture, removing clutter, sealing cracks and crevices, using traps and baits, and seeking professional pest control when needed, you can successfully eliminate earwigs from your basement. Remember to maintain good basement hygiene and monitor for signs of re-infestation. With these strategies in place, you can regain control of your basement and create a pest-free environment.
