Do coffee grounds keep bugs away?

Coffee grounds can be used fresh or used, but unused coffee grounds are more effective at repelling pests. If you have coffee that is more than 30-days past it's roast date, consider those first and get yourself a fresh roast. The smell of burnt coffee is also effective at repelling pests.

How to use coffee grounds as a mosquito repellent
Coffee grounds make an effective mosquito repellent because of the strong smell. The coffee grounds will mask the scents on humans that attract mosquitoes - if they can't smell you they can't find you! You can also burn it to create an even stronger aroma - the same way citronella candles keep mosquitoes away.
Water mixed with coffee or used coffee grounds can also slow down adult mosquitoes, kill mosquito larvae, and offer beneficial nitrogen and nutrients to plants. Note that even though this may slow down adult mosquitoes, it doesn't always prevent them from being in your space.
You can also use coffee grounds to keep other similar pests out of your garden by sprinkling them around the perimeter of the garden. Coffee grounds are toxic to many insects, and the strong smell will deter them from crossing over.
