Before we delve into the effectiveness of burning coffee as a mosquito repellent, let’s first understand why mosquitoes are attracted to humans in the first place. Female mosquitoes need blood to produce eggs, and they use their sense of smell to locate their prey.
Carbon dioxide, lactic acid, and ammonia are some of the chemicals that humans emit through their skin and breath that attract mosquitoes. In addition to these chemicals, mosquitoes are also attracted to heat and movement, which is why they tend to swarm around people who are active or moving.

Several studies have been conducted to test the effectiveness of burning coffee as a mosquito repellent.
One study published in the Journal of the American Mosquito Control Association found that burning coffee grounds repelled mosquitoes for up to three hours.

Other Natural Mosquito Repellents
While burning coffee may have some potential as a natural mosquito repellent, there are other natural options that have been found to be more effective. Essential oils such as citronella, lavender, and eucalyptus have been found to have mosquito-repelling properties.
These oils can be used in various forms, such as candles and diffusers, to create a natural barrier against mosquitoes. Another option is to use mosquito-repelling plants, such as lemongrass and marigolds, to create a natural barrier around your home or outdoor area.
