Osage Orange

Description:

Fruit of the Osage Orange tree.

Notes:

It was once thought that placing an Osage orange under the bed would repel spiders and insects. This practice has declined with the rise of synthetic insecticides. However, scientific studies have found that extracts of Osage orange do repel several insect species, in some studies just as well as the widely-used synthetic insecticide DEET. source-wikipedia
