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.

    And eradicating mosquitoes is going to help with that how exactly?

    Improved human health and well-being in cities certainly couldn’t hurt. But it’s not really meant to be part of that strategy. It’s more to prevent human suffering and death from disease.

    human suffering

    Right, so we should also eradicate all human predators to prevent human suffering at all, yeah?

    death from disease

    Malaria (and other diseases) can be eliminated. If you're in a western country, when is the last time you heard of someone (in your country) having it? Did they travel recently before* the infection?

    We have West Nile that can kill people, and many other dangerous mosquito borne illnesses are expanding.

    Predators have other effective methods to prevent them from killing people.

    But I mean I don’t really think it would be appropriate to have lions in major cities either, so you? Unless measures could be developed to coexist and keep people safe.

    If you’re really passionate about mosquitoes existing in cities for some reason and can develop alternatives that keep people safe then go for it. But despite decades of work on this topic, we’re not there yet and killing mosquitoes remains an important part of disease control in most parts of the world. The way Malaria was eliminated from large regions in the first place was through widespread poisoning of mosquitoes, so that example really doesn’t help your case.

    killing mosquitoes remains an important part of disease control in most parts of the world.

    Which was done without fully studying the ecological impacts. There are studies coming out now showing there are many impacts from doing this.

    Edit:

    can develop alternatives that keep people safe then go for it.

    Permethrin, diethyltoluamide, citronella, bug zappers and mosquito nets already exist and can help you control their presence both on your person and in a localised area.

    Most mosquito-borne illnesses are caused by a small subset of specific species of mosquito. There are only a few that cause malaria, for example. Past eradication methods, such as blanketing areas in insecticides, killed mosquitos indiscriminately, even the ones that don't carry diseases (as well as other insects). This had consequences on the rest of the food chain. Humans have tried to eradicate many species to the detriment of ecosystems. Whether that's wolves causing deer populations to explode, dingoes causing the same for kangaroos, or cane toads being brought in to control cane beetles. We just do not have a good track record of trying to eradicate species for our own benefit, because ecosystems are far more complex than we actually understand. For example, did you know that mosquitoes are pollinators?

    A far better method for controlling mosquitos in cities would be to aid in the reintroduction, protection and support of their natural predators. Those would include bats, birds and spiders, as well as lizards and amphibians in some regions. Part of that would also include the eradication of invasive species that outcompete local species, but have differing diets.
