Domingo Morales, CEO and Founder of Compost Power, builds sustainable community composting sites across New York City (NYC) with an emphasis on under-resourced and marginalized communities.
He created this Rodent Reduction Rubric based on his “diamond standard” best management practices being implemented at Compost Power’s nine composting sites throughout NYC. These practices have been recognized as being in alignment with the New York Public Housing Authority’s integrated pest management approach for eliminating the root causes of pests.
This Rodent Reduction Rubric is intended for sites utilizing the hot composting method. Vermicomposting and bokashi composting may require variations to the practices outlined in this rubric.

How to Use
Use this rubric to assess how rodent resistant a composting site is, whether it’s your own site or a site you manage or oversee. Rate your site on a scale of 1 to 3 based on the guidance across each of the four categories: System Placement, Work Surface, Compost Management, and Compost Biofilter. A passing score is 8 out of a total 12 possible points. A score of 1 in any category negates a passing grade.
Whether creating a new site or looking to improve an existing one, this easy-to-follow rubric highlights the key factors to pay attention to in order to minimize rodent risk.
