Ways to Exterminate Booklice

Booklice, or paperlice, can quickly become a nuisance when they infest books, documents, and other paper-based materials. Although they do not pose a direct threat to humans, their presence can lead to damage and degradation of valuable items. In this article, we will explore various methods to exterminate booklice effectively. By following these steps, you can regain control over your belongings and prevent further infestation.

1. Identify the Problem:

Before embarking on extermination, it’s crucial to confirm the presence of booklice. Look for small, pale insects crawling on books, papers, or walls. Additionally, be on the lookout for signs of booklice activity, such as tiny brown spots or damage to paper materials. Proper identification ensures that you’re targeting the right pest and using the most appropriate methods.

2. Improve Ventilation and Reduce Humidity:

Booklice thrive in environments with high humidity levels. To discourage their presence, improve ventilation in the affected area by opening windows or using fans. Consider using a dehumidifier to maintain humidity below 50%. By reducing moisture, you create an unfavorable environment for booklice and hinder their ability to reproduce.

3. Clean and Organize:

Thoroughly clean the infested area to eliminate booklice and their food sources. Start by removing any clutter, as it provides hiding places and promotes moisture retention. Wipe down shelves, walls, and furniture with a mild detergent solution to remove dust and debris. Pay special attention to cracks and crevices where booklice might hide. Regular cleaning and organizing help reduce the likelihood of reinfestation.

4. Vacuuming:

Vacuuming is an effective method for eliminating booklice and their eggs. Use a vacuum cleaner with a small nozzle attachment to reach into tight spots and corners. Vacuum shelves, carpets, and furniture, paying close attention to areas where booklice are commonly found. After vacuuming, promptly dispose of the vacuum bag or empty the canister outside your living space to prevent reinfestation.

5. Freezing Treatment:

For valuable or delicate items that cannot be easily cleaned or vacuumed, freezing is an effective method to exterminate booklice. Place infested books or papers in sealed plastic bags and store them in a freezer for at least 48 hours. Freezing temperatures kill booklice and their eggs, effectively eradicating the infestation. Afterward, allow the items to return to room temperature before removing them from the bags.

6. Heat Treatment:

Another method to exterminate booklice is through heat treatment. Place infested items in a sealed plastic bag and expose them to temperatures above 120°F (49°C) for several hours. You can use an oven, clothes dryer, or a dedicated heat chamber for this purpose. Heat effectively kills booklice and prevents their reinfestation. Exercise caution and follow safety guidelines when using heat treatments.

7. Insecticide Treatment:

Insecticides can be used as a targeted approach for severe infestations. Select an insecticide labeled for booklice or paperlice and follow the instructions carefully. Spray the affected areas, focusing on bookshelves, cracks, and crevices where booklice hide. Take care to use insecticides in well-ventilated areas and keep them out of reach of children and pets. Consider using natural insecticides as a safer alternative.

8. Natural Remedies:

Several natural remedies can help exterminate booklice. Essential oils, such as tea tree, lavender, or eucalyptus oil, have insect-repellent properties. Dilute a few drops of the chosen oil in water and spray the mixture on infested areas. Additionally, you can use diatomaceous earth, a natural powder that dehydrates and kills booklice. Sprinkle diatomaceous earth in areas prone to booklice infestation, such as bookshelves or corners. Reapply as needed, and make sure to use food-grade diatomaceous earth.

9. Sealing Entry Points:

To prevent future booklice infestations, seal entry points that allow them to enter your living or storage areas. Use weather stripping to seal gaps around windows and doors. Caulk cracks and crevices in walls and baseboards. Inspect and seal any other potential entry points, such as utility pipes or vents. By blocking their access, you can minimize the risk of reinfestation.

10. Professional Pest Control:

If the infestation persists despite your efforts or if you have a large-scale infestation, it may be necessary to seek professional pest control assistance. Pest control professionals have specialized knowledge, tools, and treatments to effectively exterminate booklice. They can assess the situation, provide targeted treatments, and offer guidance on preventive measures.

11. Preventive Measures:

After successfully exterminating booklice, take preventive measures to avoid future infestations. Maintain a clean and organized environment by regularly dusting and cleaning bookshelves, furniture, and storage areas. Store books and papers in dry, well-ventilated spaces. Avoid excess moisture and humidity by addressing any leaks or sources of water. By practicing these preventive measures, you can reduce the risk of booklice reinfestation.


Exterminating booklice requires a comprehensive approach that combines cleaning, improving ventilation, targeted treatments, and preventive measures. By following the steps outlined in this guide, you can effectively eliminate booklice and safeguard your books, documents, and other paper-based items. Remember to identify the infestation accurately, choose the most suitable method for your situation, and take preventive actions to minimize the risk of future infestations. With persistence and diligence, you can reclaim your space from booklice and ensure the longevity of your paper materials.
