Orange oil, also known as citrus oil, is an effective termite treatment due to its high concentration of d-limonene. This natural termiticide works by damaging the exoskeletons of termites, causing them to dehydrate and die. It also disrupts their ability to create new colonies by disrupting their well-developed communication pathways between worker and reproductive individuals. Orange oil can be used both as a spot treatment for localized infestations and as a full house rehabilitation procedure. Protective gear should be worn when using orange oil for termite control, as it is toxic to people and pets if ingested or inhaled in large amounts. Properly diluted orange oil is safe for residential landscaping with proper application methods followed.
