Insect & Disease Management

Although maintaining a tree in good health is the first line of defense against harmful insects and diseases, even healthy trees sometimes experience pest-related problems. At Guardian, we approach insect, mite, and disease problems through Integrated Pest Management (IPM).

This process begins with an accurate identification of the species and the pest. We then work together with you to determine an adequate threshold level, and we recommend pesticides only when this kind of treatment is necessary. Our technicians are state certified and trained to handle and apply these chemicals in a safe and appropriate manner. We are the preferred choice for tree disease control in Ann Arbor, MI, and the surrounding areas.
