I thought there had been other threads about this but couldn't find them. Anyone?

> But it was easy to prove warfarin was safe: a pest control officer held a series of local meetings where he ate warfarin-treated rolled oats while discussing rat control. Got to love those live demos. Eating rat poison in front of the audience to prove it is safe!

The dose makes the poison. Warfarin is prescribed as a blood thinner for humans.

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. No…

> 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 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 jus…

For me it's less fear than an instant "I must kill it / get it out of here" feeling. A big spider or centipede gives me a more intense "creepy crawly" shiver but a cockroach is way higher on the disgust scale for some reason.

Earlier quoted context omitted.

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.

Depending on where you live, those probably aren't the problematic species known as the German cockroach that typically infests human living quarters.

The big ones (oriental, not German) unfortunately come into my house pretty regularly. Setting out poison helps but hasn't rid of us of all of them.

Spiders are beneficial. Please don’t kill them. Cock roaches do spread disease. I buy Combat Source Kill Max Roach Insect Killer Gel with fipronil. https://www.epa.gov/ipm/cockroaches-and-schools

I'm aware, I don't kill spiders if I can avoid it. And I know cockroaches are nastier. I just think it's surprising that people are so visually afraid of them, since they're not a very scary-looking bug.

Growing up poor, cock roaches symbolize poverty and the run down sad places I used to live in. I can’t stand them as they bring back bad memories of my childhood.

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 ju…

where in Toronto did you live?

Definitely not my experience. Lived at Spadina & Dundas.

Tom Scott did a video a few years ago about New Zealand's attempt to eliminate rats by 2050. https://www.youtube.com/watch?v=wcp1BfPUeOc 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.

>Uruk-hai, orcs, or Balrogs Aren't they native?

Uruk-hai are GMO

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.

Not to be downer, but recent studies have not corroborated those effects.

>One of the most celebrated claims about Yellowstone’s wolves is facing a major challenge. Scientists say the study behind the famous trophic cascade story relied on flawed methods that overstated the ecological impact of wolf recovery. Their reanalysis found no evidence for a dramatic, park-wide surge in willow growth. Instead, the effects appear smaller and vary from place to place.
