Key Takeaways
- ✓Plastic bag policy disaster: Mayor John Lindsay's 1969 decision to replace metal trash cans with plastic bags increased NYC rat populations from 11% to 80-90% citywide. The policy prioritized collection efficiency (20% faster) over pest control, despite pest management students immediately predicting catastrophic rat growth.
- ✓Alberta's eradication success: Alberta Canada maintains rat-free status across 300+ miles of border using just 13 inspectors at $380,000 annually, discovering only 2-5 infestations per year (down from 600 in the 1950s). The program works because they patrol one border, educate citizens, and euthanize illegal pet rats within one week.
- ✓Container mandate challenges: Mayor Adams' 2023 requirement for 70% of New Yorkers to use latching bins could require 150,000 parking spots, hundreds of millions in specialized trucks, and daily pickups. The city tracks no compliance data and measures success only through 311 complaints, which show 20% reduction in some areas but increases in others.
- ✓Psychological impact exceeds disease risk: Scientists confirm rats rarely transmit disease to North Americans (NYC rats caught COVID from humans, not vice versa). The primary harm is psychological stress from feeling loss of control. Only 100 New Yorkers get bitten annually in a city of 8 million people.
- ✓Pet rat intelligence: Domestic rats demonstrate problem-solving abilities including coordinated teamwork to open drawers, deceptive behavior to hide capabilities from owners, and social bonding through grooming. They read human facial expressions, detect stress through smell, and study posture to predict behavior, making them highly perceptive companion animals.

Notable Moment
A single injured rat found during pandemic lockdown led one man to eventually own 37 rats over three years, getting banned from multiple adoption groups for backing out of surrenders. His rats learned to fake inability to jump high when caught stealing treats, demonstrating sophisticated deception.

Good morning. And it's a great morning for New Yorkers and a great morning to be in New York City. We had a press conference in a park at Harlem for New York's mayor Adams in April 2023. There are two undisputed truths about the Adams administration. Mayor Eric Adams loves his mother. Mayor Eric Adams hates rats. This event was to introduce New Yorkers to the brand new rat czar. This is a position the mayor created. That is job listing called for candidates who were, quote, highly motivated and somewhat bloodthirsty with a swashbuckling attitude, crafty humor, and general aura of badassery. Rats impact At the time of this press conference, New York's mayor was not popular. He had huge disapproval ratings on crime and homelessness, fewer than half of all New Yorkers liked the way he was doing his job. And we're revisiting this moment because mayor Adams is about to be replaced on January 1. And this is an episode of ours, that he inspired that we all at our show really love, where we tried some funny things that we had never tried before. It's a show about rats in New York and elsewhere and as a kind of goodbye to mayor Adams. We thought we would play this now, our last show of this year. Because when this embattled disliked mayor, mayor Adams, would talk about rats, it was with a kind of joy. It was like he was a dad whose teenage kids would roll their eyes at everything he said, but then he knew he had this one topic that was like, I don't know, taking them out for ice cream or something. Like, he knew this was at least gonna go over. We are serious about I mean, rats are a big issue. Stories. I hear it all the time. I'm on the trains. I'm walking the streets. People stop me and say, you know, we're with you, man. We hate those damn rats. And, you know, remember Julia? Remember when I came out that rat device? You know, I had a rat device. We caught 96 rats around Brooklyn, Borough Hall. 96 rats. And, you know, there were people that were yelling, you know, oh, you murderer. You murderer. You know? This is the kind of cutthroat swagger in a lot of the remarks this day. Next to the podium is a table with all kinds of gear for shooting, poisoning, and trapping …
