The large, round, inedible fruit of the Osage orange tree ( Maclura pomifera ) is often referred to as a “horse apple.” The term “horse apple” is a common name and, despite the implication, these fruits are not generally consumed by horses or other livestock. The primary usage of these fruits revolves around their purported ability to repel insects.

The fruit’s potential as a natural insect repellent has led to its placement in homes and around gardens.

Further research is needed to determine the specific compounds responsible for any observed repelling properties and their efficacy.
