Coffee grounds mosquito repellent

Coffee grounds mosquito repellent

More than half of all food produced in Canada is wasted, with the majority of it ending up in our landfills. But even some of the food you think is unavoidable to waste (like bones, egg shells, and coffee grounds) can actually be used.

This zero-waste natural mosquito repellent is a simple and effective way to reduce food waste and skip the calamine lotion this summer.

Materials Required

Used coffee grounds


  1. Sprinkle your used coffee grounds onto your garden.

  • Enjoy the great outdoors again (mosquito free!).

Bonus Tip

To give your garden some extra love, add crushed eggshells in with the coffee grounds—eggshells provide soil with extra nutrients that will help your plants thrive.
