Coffee can also be a life-saver in a case of ants infestation. It has a strong smell which blurs the ants tracks and they can’t find their way back home.
Just like with ants, coffee is effective against fleas as well. Just rub some moist coffee grounds into your dog’s skin and hair, gently massaging it with it. The fleas will disappear and your pet will smell amazing.
Place some dry coffee grounds in a fire-safe jar and light it with a match. The steam/condensation will help you dispel all the wasps in a matter of seconds. They can’t stand the smell of coffee.
