Thousands of pounds of used coffee grounds are thrown in the garbage and sent to the landfill every year. In fact, they only add to the staggering amount of garbage. Therefore, instead of dumping it into the garbage, why wouldn`t you use the coffee grounds for something better and useful, like repelling insects or fertilizing lawns? If you are interested in learning more about the ways in which you can get the most of coffee grounds, read on!
1. Mosquito Repellent
Not only mosquitoes hate the strong scent of used coffee grounds, but it has been scientifically shown that coffee has the ability to kill off mosquito larvae as well.
All you have to do to make this natural mosquito repellent is to put the coffee grounds into small dishes of water near the house, such as around the backyard or in small ponds of puddles. You can also burn the coffee grounds in aluminum foil to enhance the insect-repelling scent or pour them into a spray bottle with hot water and spray the areas where mosquitoes usually gather.
Due to its high levels of nitrogen, coffee grounds can be used as effective fertilizer. Adding coffee grounds into the planting soil stimulates the growth of microbes. Even though the microns break down, the nitrogen content remains and provides the plants with all the nutrients they need.
Many people have been put off by the idea of using coffee grounds as fertilizer as they have believed that they are acidic. However, the acid in coffee beans is soluble, which means that it gets washed away into the coffee.
3. Staining Wood
Amazingly, coffee grounds work as an alternative for DIY wood staining by giving the wood a nice and organic tone.
First, take the leftover coffee grounds and put them into a coffee pot. Add boiling water over them and allow them to sit for at least two hours. Letting them sit overnight is even better! When done, filter out the coffee grounds into a container so that a paintbrush can fit into it.
Then, soak the paintbrush into the mixture and apply it onto the wood. Wait for about ten minutes for the layer to dry and then add another layer. Repeat the procedure until you reach the wanted shade. Rub in any leftover grounds if you want even darker shade.
Given the fact that coffee grounds are abundant in nitrogen, they work as great addition to your compost pile. The nitrogen content provides bacteria in the compost with energy they need to break down the organic items, which in turn speeds up the process. Moreover, the coffee grounds neutralize the unpleasant smell. All you have to do is to put the leftover ground into the compost bin like you would do with anything else.
