Hedge apples are the fruit of the Osage orange tree, which is native to southern Oklahoma and northern Texas. Hedge apples are not poisonous, but they are an effective repellent against insects and spiders. Using hedge apples to control your spider population is an easy, chemical-free pest-control option. If you do not have access to a hedge apple tree, the fruit can be purchased at grocery stores and farmers' markets.
Place whole hedge apples in areas where spiders are seen. Set the hedge apples on a piece of tinfoil or in a small bowl to prevent the juice from ruining flooring, cabinetry or other materials in your home. Place hedge apples about two feet from areas of spider infestations.
Cut the fruit in half or crush it with a hammer to get quicker results. Opening the fruit immediately exposes pests to the milk of the fruit. Place the exposed pieces in a dish. Set the dish in the area where you most often see spiders.
Dispose of hedge apples once the majority of the green skin has disappeared. Hedge apples will last two to three months in a cool room or area.
