How to Get Rid of Woodlice in the Home Naturally

How to Get Rid of Woodlice in the Home Naturally: Woodlice, also known as pill bugs or sow bugs, are small crustaceans that are commonly found in moist and damp areas of homes. While they are harmless and do not pose any direct threat to humans, their presence can be undesirable and indicate underlying moisture issues. If you’re looking for natural ways to eliminate woodlice from your home, this article provides effective methods that are safe, eco-friendly, and free from harmful chemicals. By following these natural solutions, you can successfully control woodlice populations and create a healthier living environment.

Identify and Eliminate Moisture Sources

Identifying and eliminating moisture sources is crucial in addressing woodlice infestations, as these pests thrive in damp and humid environments. By taking the following steps, you can effectively reduce moisture levels in your home and discourage woodlice from taking up residence:

  1. Check for Leaks: Inspect your plumbing system, including pipes, faucets, and toilets, for any leaks. Repair or replace faulty components promptly to prevent water accumulation.
  2. Address Condensation Issues: Excessive condensation can contribute to high humidity levels. Use dehumidifiers or improve ventilation in areas prone to condensation, such as bathrooms, kitchens, and basements. Consider installing exhaust fans or opening windows to promote air circulation and reduce moisture buildup.
  3. Monitor and Address Basement Moisture: Basements are prone to moisture problems. Ensure proper waterproofing by sealing cracks in walls or floors, installing a sump pump if needed, and utilizing moisture barriers or dehumidifiers to control humidity levels.
  4. Maintain Proper Ventilation: Proper airflow is essential in preventing moisture buildup. Ensure that vents in bathrooms, kitchens, and laundry areas are clean and unobstructed. Use exhaust fans or open windows during and after activities that generate moisture, such as cooking or showering.
  5. Insulate and Seal: Insulate cold surfaces, such as pipes and windows, to prevent condensation. Seal gaps and cracks in walls, floors, and foundations to prevent water infiltration and reduce humidity levels.
  6. Remove Standing Water: Check your home’s exterior for any areas where water tends to accumulate, such as clogged gutters, improper grading, or pooling around the foundation. Correct these issues to prevent water from seeping into the house and creating moisture problems.
  7. Monitor and Maintain Outdoor Drainage: Ensure proper drainage around your home’s perimeter. Regularly clean and maintain gutters, downspouts, and drains to prevent water buildup near the foundation.
  8. Properly Dry Wet Areas: If any water spills or leaks occur, promptly dry the affected area to prevent moisture from lingering and creating favorable conditions for woodlice.

Improve Indoor Ventilation

Proper ventilation is essential for reducing humidity levels and discouraging woodlice infestations. Increase air circulation by opening windows, using fans, or installing ventilation systems in areas prone to dampness. This helps to dry out the environment, making it less favorable for woodlice to thrive.

Seal Entry Points

Woodlice can enter your home through small cracks and openings. Seal gaps around windows, doors, pipes, and utility lines to prevent their entry. Use weatherstripping, caulk, or sealant to seal off potential entry points, effectively denying woodlice access to your home.

Remove Excess Organic Material

Woodlice feed on decaying organic matter, such as fallen leaves, mulch, or compost. Remove any excess organic material near your home’s foundation or in the immediate vicinity. Clear debris from gutters, trim vegetation away from the house, and maintain a clean yard to reduce food sources and discourage woodlice from taking up residence.

Natural Repellents

Several natural substances can act as deterrents to woodlice. Consider the following options:

  • Diatomaceous Earth: Sprinkle food-grade diatomaceous earth around entry points, damp areas, or places where woodlice are frequently seen. The abrasive particles of diatomaceous earth dehydrate and damage their exoskeletons, effectively repelling and killing woodlice.
  • Citrus Peels: Place citrus peels, such as lemon or orange, in areas where woodlice are present. The natural oils and scent of citrus act as a repellent, deterring woodlice from those areas.
  • Essential Oils: Mix a few drops of essential oils, such as peppermint, eucalyptus, or tea tree oil, with water and spray the solution in infested areas. Woodlice are known to dislike the strong scents of these oils, helping to keep them away.
  • Cucumber Slices: Place cucumber slices near woodlice habitats. Cucumbers contain compounds that repel woodlice, making them a natural deterrent.

Natural Predators

Natural predators play a valuable role in controlling woodlice populations and maintaining a balance in the ecosystem. Introducing these beneficial creatures into your home and garden can help control woodlice infestations in a natural and eco-friendly manner. Here are some common natural predators of woodlice:

  1. Spiders: Spiders are known to prey on woodlice. Species such as cellar spiders, cobweb spiders, and daddy longlegs are particularly effective at catching and feeding on woodlice.
  2. Ground Beetles: Ground beetles are voracious predators that actively seek out woodlice as a food source. These beetles are fast-moving and have sharp mandibles, allowing them to capture and consume woodlice efficiently.
  3. Centipedes: Centipedes are natural predators of woodlice and other small arthropods. They have long, segmented bodies with numerous legs and venomous pincers, enabling them to hunt and feed on woodlice effectively.
  4. Birds: Several bird species, such as robins, blackbirds, and thrushes, feed on woodlice. Encouraging bird activity in your garden by providing birdhouses, feeders, and water sources can help control woodlice populations naturally.
  5. Amphibians and Reptiles: Some amphibians and reptiles, like frogs, toads, lizards, and snakes, feed on woodlice. Creating suitable habitats for these creatures, such as ponds or rock piles, can attract them to your garden and provide natural pest control.
  6. Predatory Mites: Certain species of predatory mites, such as Hypoaspis miles, are effective at feeding on woodlice and other small pests. These mites can be introduced to the soil or mulch around infested areas to control woodlice populations.

Regular Cleaning and Maintenance

Maintain a clean and clutter-free home to discourage woodlice infestations. Regularly vacuum and sweep floors, especially in damp areas. Pay attention to hidden corners, basements, and crawl spaces. Declutter storage areas to eliminate hiding spots for woodlice.


Woodlice infestations can be effectively controlled using natural methods that prioritize the safety of both residents and the environment. By addressing moisture sources, improving ventilation, sealing entry points, removing organic material, employing natural repellents, introducing natural predators, and maintaining cleanliness, you can successfully get rid of woodlice in your home naturally. Remember, prevention and regular maintenance are key to long-term success. By adopting these natural strategies, you can create a healthier and woodlice-free living space.
