The podcast explores the challenges of controlling rat populations in big cities like Chicago, Washington, DC, and New York. It discusses the efforts made by cities, including hiring a rat czar in New York. The podcast features interviews with a rat control squad, a rodentologist, and the New York Sanitation Commissioner. It highlights the difficulty of controlling rats due to their rapid reproduction and human behavior. The podcast also explores the importance of understanding rat behavior, estimating rat populations, managing waste, and controlling their food supply.

The Dangers of Rats: Disease, Property Damage, and Safety Hazards
Rats are not only unsightly but also pose serious risks to public health, property, and safety. They live in dirty areas and can carry and spread about 55 different diseases, some of which can be fatal. Rats can damage buildings by burrowing in between floors and chewing on electrical wires, causing potential fire hazards. The increasing rat population in cities can be attributed to factors such as global warming, urbanization, and the abundance of food sources like garbage. Controlling the rat population is crucial to minimize the risks they pose.
Methods of Rat Population Control: Inspecting and Treating Rat-Infested Areas
Effective rat population control requires understanding their behavior and habitats. Urban rodentologist Dr. Bobby Corrigan suggests visually searching for signs such as burrows and greased stains, which indicate active rat populations. For instance, observing decaying infrastructure, like deteriorating sidewalks, reveals potential rat harborages. To control rat populations, methods like pumping carbon monoxide into burrows are used to suffocate rats. Other techniques include using tracking powder, which rats ingest and die from grooming. Attempts to introduce rat contraception and feral cats as control methods have faced challenges.
The Impact of Urban Waste on Rat Populations: Trash as a Food Source
Rats heavily rely on trash as a source of food, and the abundance of garbage in cities directly correlates with rat populations. During periods of reduced access to restaurant garbage due to lockdowns, rat populations decreased. However, the resumption of city activities has led to a resurgence in rat populations. Effective waste management, including reducing the time trash sits on curbs and limiting access to food sources, is vital in controlling rat populations. The pandemic's impact on waste generation highlights the correlation between waste management and rat control efforts.
Challenges and Strategies for Rat Control: Community Involvement and Environmental Awareness
Controlling rat populations requires the active participation of communities and individuals. Proper waste disposal, securing trash cans, and reporting rat-infested areas can contribute to rat control efforts. However, the collective responsibility can be a challenge since many people are not focused on rat control in their daily lives. Raising awareness about the risks posed by rats and emphasizing the importance of waste management can help engage communities in rat control initiatives. Additionally, cities must invest in comprehensive and proactive measures, including sanitation services and infrastructure maintenance, to stay ahead of the growing rat problem.
We're taking a break for the holidays, so here's an episode you might have missed.
The number of rat-related complaints in American cities has spiked in recent years. In the most overrun cities – Chicago, Washington, DC and New York – officials are stepping up efforts to find and kill them. New York is going so far as to hire a rat czar in charge of stamping them out.
Good luck with that. Cities have tried and failed for decades to control rats. So what can be done to contain the population of these rapidly reproducing rodents?
To answer that question, Big Take podcast producers Kathryn Fink, Rebecca Chaisson and Sam Gebauer hit the streets with a rat control squad in Washington and rodentologist Dr. Bobby Corrigan in New York. We also speak with New York Sanitation Commissioner Jessica Tisch. The good news: we can bring rats under control. The bad news: human nature means we probably won’t.
