It's not completely possible but if you could create a situation where mortality is so high or reproduction is impossible for them, you could keep populations very low even if some wander in.

They have genetically modified mosquitoes that cause sterility in the ones they mate with, which have been used successfully to greatly reduce the population of the species in question. So this is the best existing technology IMO but it probably will require a confluence of techniques.

But care should be taken that it doesn't harm non-target organisms and doesn't spread out of control.

For sure. That’s why we need to densify our cities to stop them from expanding. But that’s a separate question from whether it’s worth it to have mosquitoes in existing cities. I don’t think it is but if you have an argument for it go ahead.

But the vast majority of urban mosquitoes are introduced species anyway.

I weridly pick my own species over others anytime

Yeah, we went to Iceland ~3 years ago and we learned beforehand to bring a mosquito net for Lake Myvatn. So this headline confuses me. The article says mosquitoes were only discovered there this month, but some random blog knew about it years ago?

Yeah, I wish I'd known what that translated to before I went there.

At least they seemed to stay away from the thermal baths area.

Or Breed the ones that don't bite humans or whatever

Those mosquitos aren’t going to like it when it’s just sea water.

Yep I'm British and I've lost count of how many times a denier has said "no cos we used to grow grapes in England"

Yeah, probably this. And the increase in temperature simply made the conditions bearable when they got outside.

Could they have also maybe just.. flown over there? Insect migrations like this can happen, but I don't think it's possible on such a scale, even for mosquitoes.

Every day animals are adjusting their habits and habitats based on the changing environment.

...or going extinct, like a sizable number of species already had in the last few decades

Don't worry, if you're right you'll be dead. And if you're wrong you'll get to live. Truly a win win.
