My requirements are unique. I must balance the health and appearance of my lawn, with a service that uses compounds that do not cause harm to my Chihuahua that loves to be outside where I am most of the time. The ingredients at the concentration levels PB applies provides that perfect balance. Other company's chemicals will provide a more robust growth, but are quite toxic to people and pets. Pest Bear has been my provider for over two years. I still receive complements on the appearance of my yard by persons passing by, and even more important, my Chihuahua is just fine. His vitality even impresses our veterinarian.
