Rat and Insect Reports in San Francisco
San Francisco's rat and insect reports mapped.
We created a map from rat and insect activity reports made via San Francisco's 311 service. The rodent activity data covers the years 2010-2020, and shows significant year-on-year changes up until 2018. This can be seen in our rat report year-by-year breakdown:
|Year||Number of Insect and Rodent Reports|
The year 2018 was paricularly bad for rat infestations, showing a 500% increase in the number of reports when compared to 2010. Thankfully, insect and rodent sightings seem to have reduced somewhat by 2020, albeit only by 4%.
