Harris Spider Repellent Spray uses natural cinnamon and peppermint plant oils to repel spiders in indoor and outdoor settings. The 20oz spray deterrent is long lasting, safe and has a pleasant scent to humans that spiders can't stand. Simply spray our spider control solution in the affected areas around your house/home in place of a traditional spider killer or spider traps. This will help deter spiders from entering your garage, kitchen, bathroom, or even vehicle or RV. For the very best results repeat according to label directions. Take back control of your home and keep the spiders away!
