What to spray on furniture for lice?


When it comes to dealing with lice infestations on furniture, it is crucial to take prompt action to prevent further spread and eliminate these pesky insects. In this article, we will explore the different options available for spraying furniture to get rid of lice effectively.

Understanding Lice Infestations on Furniture

Lice infestations can occur not only on human scalps but also on furniture, particularly upholstered items such as sofas, chairs, and mattresses. Lice can survive for a short period away from the human scalp, making it essential to treat infested furniture to prevent reinfestation.

Materials Used for Treating Furniture

Insecticides: Insecticides specifically formulated to kill lice can be used to treat furniture. Look for products that contain ingredients such as pyrethrin or permethrin, as these are known to be effective against lice. Always follow the instructions provided by the manufacturer when using insecticides and ensure proper ventilation in the area.

Steam: Steam treatment can be an effective method for killing lice and their eggs on furniture. Using a steam cleaner or a handheld steamer, apply hot steam to the infested areas of the furniture. The high temperature of the steam helps to eradicate lice and their eggs. However, it is important to note that steam treatment may not be suitable for all types of furniture, so check the manufacturer’s recommendations before proceeding.

Essential Oils: Certain essential oils have been found to have insecticidal properties and can be used as a natural alternative to chemical-based sprays. Tea tree oil, lavender oil, and eucalyptus oil are known for their lice-repellent properties. Dilute a few drops of the chosen essential oil in water and spray it on the furniture, focusing on the infested areas.

Application Techniques

Spot Treatment: If only specific areas of the furniture are infested with lice, spot treatment can be an effective method. Use a spray bottle to apply the chosen treatment directly to the infested areas, ensuring thorough coverage. Pay close attention to seams, crevices, and any other areas where lice may hide.

Full Coverage: For more extensive infestations or to ensure complete eradication, it may be necessary to treat the entire furniture piece. In this case, spray the chosen treatment evenly over the entire surface of the furniture, including the back, sides, and cushions. Allow the treatment to dry completely before using the furniture again.

Precautions and Safety Measures

Protective Gear: When using insecticides or essential oils, it is essential to protect yourself by wearing gloves, a mask, and eye protection. This will help prevent any potential skin irritation or inhalation of harmful fumes.

Avoid Direct Contact: If using chemical-based sprays, avoid direct contact with the treated furniture until it has dried completely. This will prevent any potential skin irritation or ingestion of harmful chemicals.


Taking immediate action to treat furniture infested with lice is crucial to prevent further spread and reinfestation. Whether using insecticides, steam, or natural remedies like essential oils, it is important to follow the recommended application techniques and safety precautions. By doing so, you can effectively eliminate lice from your furniture and create a lice-free environment.
