Alberta has shown us that proper policy incentives can drive meaningful change. Instead of leaving rats to languish in cellars, they created incentives for them to do meaningful work in the provincial government instead.

The irony that they figured out how to eliminate rats, but can’t diversify from oil and gas is pretty special.

Also, many of them are sepa-RAT-ists.

Tom Scott did a video a few years ago about New Zealand's attempt to eliminate rats by 2050.

The program is actually called "Predator Free 2050" and also aims to eliminate possums and stoats. No mention is made of Uruk-hai, orcs, or Balrogs.

Aren't they native?

Had they not been so greedy mining for mithril, maybe there wouldn't have been Balrogs. Not sure if that makes Balrogs invasive.

Aren't there only a few of them? Is a few invasive?

How does a balrog reproduce btw?

Got to love those live demos. Eating rat poison in front of the audience to prove it is safe!

I wonder if we stopped trying to eradicate coyotes we might have an easier time with rats. I personally would rather see a coyote than a rat.

This inevitably brings us to the story of the reintroduction of wolves in Yellowstone, and how they eat the deer which brings back a whole new slew of changes.

I live in Alberta. No rats here. Also the ticks here don't spread Lyme disease.

They likely spread rocky mountain fever instead, if they are dog ticks like we have in Colorado.

Albertan here too. Can confirm no rats

My friend got Lyme disease from a tick though so I can't agree with that part

Great read. I didn't know how exactly the rats were eradicated from Alberta something I have just heard and taken for granted. Reading the article provided a great overview of how much effort it really took to do it.

I would like to mention that, even though Alberta is rat free, we still have mice that can make your life misreble if they somehow enter your house/office.

So, even impossible things can be made possible if there's enough determination and political will.

eliminate smallpox. Check.

Every so often I'll mention online that Alberta has no rats, and inevitably there will be an American responding in absolute disbelief saying I'm full of shit.

I may not live in Alberta, but luckily rats aren't really a thing in my neck of the woods. Travel an hour down the highway and it's a different story.

Also, as an aside, people often don't believe me when I say I've never seen a cockroach before in my life. Not a one. I've seen pictures of em, and I'm pretty sure if I saw one of those things irl I would absolutely shit myself.

I spent the first half of my life in Alberta; had never seen a rat nor a cockroach. I moved further east in the country, cockroaches in my first apartment the first week there... and then discovered rats near the waterfront within the month.

My dad and uncles lived near the southern border as kids, would hunt rats by the train station/grain elevator with a .22 back in the 50's & 60's.

"Alberta has no rats" is a bit of a simplification, as the linked article goes into in depth. They do find rat investations (typically) in the border zones, and some sneak through, both wild and domesticated. Due to ongoing management though the statement is true in broad strokes. We have lots of mice and all sorts of ground squirrels (including a ridiculously awesome "museum") but thankfully very few rats.

Canada's shipping ports have had rat infestations for hundreds of years, even up the Great Lakes. DNA studies show that once a local population became established long ago, it defended itself repeatedly from incursions, and carries on. Alberta has no sea ports, so rats hitch rides there on trains, trucks, and in packaging. The scale is much, much smaller, so Alberta is somewhat able to eradicate them.

I always thought this was interesting (how many people are super scared of cockroaches). I'm absolutely terrified of bugs, I see cockroaches very rarely, and while I wouldn't pet one... They're not too bad? There's tons of bugs that are way scarier. Spiders, house centipedes, camel crickets. And that's just the stuff that actually exists near me. If I encountered an average Australian insect, good God, I'd run screaming. But cockroaches? Eh

I assume it's because cockroaches are associated with filth, and they tend to occur in large numbers. But as individual bugs, on the surface level they're not too bad. (Not "disagreeing" or anything, just think the different perspectives are neat)

Living in a warm climate US city i noticed roaches almost disappeared once off the first floor, i saw only one in five years in a 7th-floor apartment.

I live in a wooded, fairly rural area and I see cockroaches outside, under leaves, fallen branches, etc. but they don't really come into the house.

That one is pretty shocking. When I lived in South Carolina I remember I used to walk this one road late at night. Once it was dark enough I could see them scattering underneath the streetlights on the fucking sidewalk. Reminded me of sidewalk lizards in Florida, but grosser. I live in the Midwest now. I’m just glad they’re smaller here and don’t fly.

Re: cockroaches, I haven't seen them until my mid 30s, when I started traveling to warm countries.

Don’t receive shipments of goods from out of province then. Vermin get transported in packaging easily.

Alberta of course has rats. Short of being a hermit nation with impassable borders, the alternative is impossible.

But they maintain such a critically low number through aggressive, non-stop actions that we declare it "rat free", though that's a misnomer. Similar to the measles free status doesn't actually mean measles free, but rather that it isn't spreading uncontrolled.

Though as someone who lives in Ontario, I just wanted to add that I've never seen a vermin rat in my life in this province. Not in Toronto or its subways, not on its streets, nor in various other cities throughout the province. I've seen mice, of course, but never rats. I know they exist here, but someone having not experienced them doesn't mean much.

This bit made me laugh

But wild rats are rare. Albertans have grown so unaccustomed to rats that they frequently mistake squirrels, gophers, and other small animals for them: of the 875 reported sightings in 2025, only 47 turned out to be actual rats.

I've seen plenty of rats in Toronto. I used to live around Chinatown and I could practically punt a rat just walking out my door at night.

I lived in Chinatown in Toronto (College and Spadina) and I saw a rat the size of a cat running around the inside of a Chinese supermarket around 2am when I was walking around at night during my university years. I also saw smaller rats and roaches running around Chinese restaurants as well.
