Garlic extract (Allium sativum), Lemon (Citrus limon), and ground coffee beans (Coffea arabica) against mosquitoes (Culicidae) as humidifier drops

Mosquitoes pose a threat to human health due to their ability to spread diseases. Although effective, Chemical-based repellents have harmful effects. Therefore, it is essential to look for safer, environmentally friendly alternatives. This study investigates the effectivity of natural ingredients: lemon, garlic, and ground coffee beans when used as humidifier drops to repel mosquitoes. The main objectives of the study were to determine the ingredients’ right concentration for repelling mosquitoes, measure the effectiveness and duration of their odor, and analyze user preferences for their acceptability and overall satisfaction.
A survey questionnaire was used in the study to collect data from the twenty-one respondents. The results showed that the solution effectively repelled mosquitoes and released a continuous aroma for 3-4 hours. It started working as a repellant within five minutes of the humidifier being opened and continued to work long after the mist disappeared. The respondents strongly agreed that the natural humidifier drops made from lemon, garlic, and coffee grounds were easy to use, fragrant, highly effective, and sustainable. The participants expressed their willingness to continue using these drops and recommended them to others. The study supports the potential of lemon, garlic, and coffee extract-based humidifier drops as a natural and effective approach to repel mosquitoes. They are good alternative for Chemical-based repellents because of their effectiveness, sustainability, and cost-effectiveness.
Overall, this study contributes to the understanding of eco-friendly mosquito repellents. The use of natural ingredients as a safe, effective solution is backed by positive feedback and high satisfaction from participants.
