Wormwood incense

Wormwood can effectively repel mosquitoes and some uninvited insects in your house. Compared to chemical sprays, it is 100 percent safe for adults and children.

Incense is often made from wormwood that has been dried for at least three years. The longer the wormwood is dried, the stronger effect it will have. Wormwood dried less than three years will not function as well as you expect.
