No ticks at the altitude I reside. But with global warming it's slowly creeping up towards the towns further down. Same with Spanish slugs. Will soon be able to thrive here as well.

We have dog ticks at 8000 feet in Colorado, not sure how much altitude affects them.

I think temperature is the relevant variable

Ticks are a problem regardless. And they don’t like too much heat. So climate warming may even reduce their population in some parts. Or, more likely, move them up north. Giving relieve to some and headache to others… Lyme disease vaccine would help a ton though. I’ve had Lyme 3 times by now. Thankfully encephalitis stab is a thing.

I don't understand why we're not vaccinating deer populations, even if we're not vaccinating humans out of safety concerns, etc. That and deer populations need to be significantly culled (along with rodents, the other part of the Lyme / deer tick population cycle). In any case, lack of long consistent extended cold spells in the winter to set back their breeding population is the reason they've moving further north.…

Yep, we should extend the deer hunting seasons so we can vaccinate 'em with lead (I'll leave the rat hunting to others).

> So the issue is that more northerly areas are getting much more variance in temperature and lacking long deep consistent cold periods. It impacts the population, but even a couple solid weeks of -20C weather doesn't seem to be enough to eradicate them.

Ticks have always been around Ottawa, and even in 2011? I recall -40C for well over a week, and obviously cold temps around that week. Insects lay eggs, and also go dormant under fallen leaves typically. The snow + leaves insulates them, it's how live insects survive the winter. If you watch robins in the spring, before the ground thaws, you'll see them flipping over leaves. They're eating loads of insects hiding, mo…

If there was more diversity in predators and prey, the population cycles would have smaller amplitudes. The large swings are often symptoms of a collapsing ecosystem.

Don't know which is worse - - contracting Lyme disease, or Parkinson's disease from Permethrin and other pesticide exposure: https://beyondpesticides.org/dailynewsblog/2009/09/occupatio... https://pubmed.ncbi.nlm.nih.gov/27756609/

What's interesting about this study is that ticks were reduced by 50% with untreated woodchips (no pesticides!)

I mean, yeah. Ticks live in grasses not on the ground. If you walk on bare trail and don’t brush on grass or other plants your chance of a tick is much lower

It's only hazardous when wet. I spray my clothes and then let them dry on the clothesline.

We need a vaccine for Lyme disease, it would be a lot more effective than paying $3K per kilometre of path per year.

One existed, it was pulled from the market in the early 2000s. There's still a dog one, and there is at least one which is in late stage trials in the US today.

Linen clothes are awesome. Long trousers and long sleeves and almost as cool as short sleeves and shorts in shade, and cooler in direct sun.

Linen is the most underappreciated fabric. It's cool in both ways. I don't understand why so few people wear linen in summer.

I would like to but they are frustratingly hard to find

Or avoid the trails all-together. Given the 30th anniversary of Trainspotting this seems relevant: https://youtu.be/xtbS_PdA198?si=8ba8Fp8_uzdpIq6J . I’m pretty wary of ticks, when you go for hikes just do a body check after. Also, I tend to go with long pants (even in summer, I dislike bugs more than the sweat). Plus a lightweight windbreaker can help to cover upper body. Plus it limits sun exposure which is also ha…

Tell me your linen ironing tricks. I have a linen shirt that I dread wearing because of the effort that goes into getting it wrinkle free after every wash.

Rodent populations are notoriously hard to control. But it seems that a deer cull would be easy. I am surprisec that they are not done.
