Orange oil, an extract from orange peels, is effective in controlling termites. Orange oil is not considered an absolute eradicator of a termite population, but it does allow for the management of an existing infestation.
The primary active ingredient in orange oil is D-Limonene. This ingredient is a chemical known to be a successful insecticide against various pests, including ants, flies, mosquitoes, crickets and termites. According to scientists, orange oil wears away at the termite exoskeleton and ultimately leads to termite demise due to immense water and protein loss. Orange oil is one of the best non-toxic ways to control a average termite infestation.
