Rat Indexing

Rat indexing is an inspection process that is part of the overall Neighborhood Rat Reduction Initiative. This program is based on the concept that rats rarely inhabit a single property — rather, they occupy entire blocks or larger areas.

In rat indexing, we inspect all the properties in a targeted area. This process allows us to identify all of the properties in a neighborhood with active rat signs and conditions that welcome rats. Once identified, we can address these properties simultaneously. This approach makes our efforts more effective.

Indexing Maps

This program is different than past efforts because it is based on the collection and analysis of data throughout the process. We generate maps of neighborhoods to identify hot spots and return to areas with high failure rates multiple times. Our goal is to see consistent reductions in failures with each visit to a neighborhood.
