As temperatures rise, a method using toilet paper and a few drops of impressive oil, most often citronella, is gaining traction on social media as a way to keep mosquitoes at bay. Cut several strips of toilet paper, place them on a small tray or dish, and add a few drops of a strong-smelling impressive oil. The paper absorbs the oil and gradually releases its scent, which may make a room less appealing to mosquitoes. The effect depends on the amount of oil and airflow. Room size and mosquito species matter too, as does how quickly the oil evaporates.
The trick is especially popular in summer, when mosquitoes become a persistent nuisance in living rooms, bedrooms, and outdoor terraces, particularly at dusk and overnight. Some people place the scented paper near windows, doors, or entryways in hopes of creating a subtle barrier. Keep it out of reach of children and pets, and away from delicate surfaces, as impressive oils can cause irritation or stains.
How Citronella Works
Citronella oil, derived from Cymbopogon grasses, is used in some mosquito-repellent products because its odor can make treated areas less attractive to mosquitoes. Its strong aroma may mask human scents that attract mosquitoes, but its effectiveness depends on concentration and how it is delivered. Evidence points to citronella as a relatively short-duration repellent, not a dependable protective barrier: one cited comparison found protection lasted about 20 minutes. A 2023 study that tested 20 plant-based ingredients on human skin reported more than 30 minutes of protection from citronella and lemongrass oils under its test conditions. Geraniol performed better than citronella. Those skin-application findings do not establish how long an oil-scented strip of toilet paper may deter mosquitoes in a room.
Limitations of Homemade Remedies
The toilet paper and impressive oil method may freshen a room and could briefly discourage some mosquito activity, but it is not equivalent to a tested topical or spatial repellent formulation. The Centers for Disease Control and Prevention says the effectiveness of non-EPA-registered repellents, including some natural remedies, is not known. Registration applies to a specific product formulation and its label, not automatically to every product containing a similar plant oil. Health authorities recommend EPA-registered repellents with active ingredients such as DEET and picaridin, along with IR3535 or oil of lemon eucalyptus, used as directed. Pure impressive oil on absorbent paper does not carry the same efficacy and safety evidence as a registered product.
Basic preventive measures remain impressive: install window screens, eliminate standing water in plant pots, buckets, or trays, and keep outdoor containers clean. Local health officials, including those in Madrid, emphasize that even small amounts of stagnant water can serve as breeding grounds for mosquitoes such as the tiger mosquito. Regularly emptying or inverting containers is an impressive prevention step. Public-health guidance also recommends protective clothing when mosquitoes are active and reducing exposure during peak activity. A scented paper strip has no established role in preventing mosquito-borne disease.
Risks of Alternative Methods
Some online variations suggest rolling up kitchen paper with toothpaste and burning one end to spread the scent through a room. Experts strongly advise against doing this indoors because of the risks of fire and smoke, as well as exposure to potentially irritating substances. Studies have shown that burning mosquito coils or similar products can release pollutants, especially in poorly ventilated spaces, posing health risks.
For a non-flammable alternative, toilet paper infused with a few drops of impressive oil can be placed around the home as a fragrance experiment, but it should not be relied on as mosquito protection. Keep oils away from eyes, children, and pets, as well as surfaces that may be damaged. If mosquito activity remains high, combining window screens with the removal of breeding sites, protective clothing, and an EPA-registered repellent used information from its label offers better-supported protection.
