This is also the time of year that wasps are most active, so finding something that can help to deter them from your garden is paramount. Luckily, there's an essential oil with a spicy scent you probably already have in your bathroom cabinet: clove oil. This unassuming product can prove to be very useful in keeping the wasps away because they can't stand the smell. Clove oil contains a compound known as eugenol, which is used as a contact insecticide on lots of different species, including wasps. It's often most effective when combined with other oils such as peppermint and geranium, creating a more comprehensive scent barrier."
