Coffee is the second most traded commodity in the world! With millions of pounds of coffee grounds being used per day, people have found additional uses for used coffee grounds.

This includes, but is not limited to, mixing it with soil in their gardens, using it in compost, and repelling garden-killing pests like slugs and snails.

While we know it can keep garden-variety pests away, can coffee grounds repel mosquitoes? We dove in to find out.

Can You Use Coffee Grounds to Repel Mosquitoes?

The short answer: maybe.

The long answer? It depends. There are many conflicting claims about whether or not coffee grounds repel mosquitoes. Our findings suggest that, well, it kind of does.

One study from 2015 found that adding coffee grounds to standing water will deter most female mosquitoes from laying eggs in it, but that’s about it.

According to the same study, adding coffee grounds, or coffee itself, to standing water will kill mosquito larvae if any are present.

The EPA has stated sprinkling coffee grounds around your garden or backyard can help keep pests away such as ants, slugs, snails, and fleas. Unfortunately, there’s no mention of flying insects such as mosquitoes.

Simply having coffee or coffee grounds sitting out will not repel mosquitoes.

Can You Burn Coffee Grounds to Deter Mosquitoes?

Burning coffee grounds should be an effective way to repel mosquitoes.

There is no scientific proof burning specifically coffee grounds works. However, there is a lot of evidence that proves smoke repels mosquitoes.

Mosquitoes tend to steer clear of strong smells and smoke because it irritates their scent receptors. Besides the irritation factor, the fear of smoke is ingrained in their DNA because it generally means “danger” in nature.

Because of this, there is a good chance that burning anything, including coffee grounds, will work as an effective mosquito repellent.

Ways to Repel Mosquitoes in Your Yard

While burning coffee grounds might work, there are scientifically-proven ways to naturally get rid of mosquitoes in your yard.

Some of our favorites include:

  • Use plants that repel mosquitoes, including Marigolds, Rosemary, and Mint.
  • Remove standing water – this is a breeding ground for mosquitoes
  • Kill mosquito larvae by using cinnamon essential oil or vinegar
