What We Do

At Grass Systems Entomology, our mission is to help you interpret and resolve insect pest management challenges. 

We do that by applying science to the understanding and management of turf-infesting, grass-feeding and soil-dwelling insects, giving you the tools, confidence and backstopping to overcome hurdles and implement positive changes.

As an independent consulting firm, we are driven to tailor our analyses and approaches to your needs, avoiding the constraints of standard packages and one-size-fits-all.  Your singular challenge merits an exceptional response.

To learn more about how we can help you get a grip on your grass, visit Our Services, Our Insects and Our Agroecosystems.  Then Contact Us so Grass Systems Entomology can begin to guide you around your barriers and back into business better than before.
