Gabrielle LaTora, a specialist in agricultural entomology who operates as an agriculture and natural resources agent with UGA Cooperative Extension, conversed with Better Homes & Gardens regarding the importance of citrus peels as a natural insect deterrent.

Can horticulturists utilize citrus peels to ward off pests? The concise answer is no.

“There’s insufficient scientific proof that [citrus peels] fend off insect nuisances,” LaTora stated.

Although the essential oils and extracts derived from citrus peels are effective in repelling insects like carpenter ants and cockroaches, these substances are only effective when utilized in substantial concentrations—far exceeding what is contained in the peel itself.

“This means that your discarded orange peels likely lack the potency to have any significant repelling effect,” LaTora remarked. “There’s a fleeting window during which the oils in the peels evaporate and disperse into the surrounding air, but they aren’t dense enough to create a meaningful deterrent. They dissipate too rapidly and become so diluted in the atmosphere that they won’t repel insects.”

Nonetheless, citrus peels possess their own merits. Like other food remnants or organic matter, citrus peels contribute nitrogen and additional nutrients to the soil, positively impacting plant health.

“The essential factor is that citrus peels should be harmonized with other materials and thoroughly composted prior to incorporating them into the garden to maximize their benefits,” she advised.
