Please note: Do not use with poison. Our product, formerly known as Marder Spray, has the same formulation under a new name. It contains aromatic substances designed to prevent marten odor traces in the engine compartment. This easy-to-use spray helps prevent expensive repairs by safeguarding plastic and rubber components. Simply spray all plastic and rubber parts from all sides and reapply approximately every 14 days. Remember to use biocides safely and always read the label and product information before use.
