5) Eucalyptus
This plant is well known for its healing properties, but it is also an excellent mosquito repellent. The smell of its leaves acts as a repellent and keeps many other insects away. Eucalyptus, unlike the plants previously described, is not easy to plant and care for. Precisely because of its considerable size, it can grow up to 25 meters and is therefore suitable only for very large gardens. In addition, it is very important to prune it in spring, to allow it to continue growing.
