Las Vegas' growing mosquito problem is 'a ticking time bomb'

The insects are not only a nuisance, but they also pose a major threat of mosquito-borne diseases such as dengue fever and West Nile virus.

LAS VEGAS — If at one time it was thought mosquitoes couldn’t survive in desert climates, this city is a case study in how wrong that is.

Mosquitoes typically prefer more tropical, humid conditions, but these biting machines have exploded in number throughout the Las Vegas Valley in recent years because of a host of changes.

A mix of urban development, climate change, insecticide resistance and genetic adaptations are creating a more hospitable environment for the insects in southern Nevada.

Las Vegas is hardly alone in its battle against the pesky insects. Warmer temperatures and shifting weather patterns are expanding the geographic range in which mosquitoes live and breed. In many ways, what’s happening here is playing out across the desert Southwest and beyond.

The mosquitoes have brought with them not only the nuisance of bug bites, but also the major threat of mosquito-borne diseases such as dengue fever and West Nile virus to Las Vegas and the rest of Clark County.

It's also caught people off guard.

“People aren’t wrong that mosquitoes shouldn’t really thrive in desert conditions, but it’s clear that the particular set of species that we do have in Clark County has adapted to the local ecology,” said Louisa Messenger, an assistant professor in the department of environmental and global health at the University of Nevada, Las Vegas.

'A ticking time bomb'

The species that have taken hold in Clark County include Culex mosquitoes, which can carry West Nile virus, and Aedes aegypti mosquitoes, the primary spreaders of dengue. What’s more, Messenger and her colleagues at UNLV have found that mosquitoes...

We've got a mosquito infection around here, too...



They buzz around the yards making all kinds of noise for no apparent reason. I don't think they're indigenous.

I thought I remembered that Gates was trying to chemically alter mosquitoes where they could still reproduce but wouldn’t bite for blood.

He supposedly let loose a swarm of his altered skeeters on an unsuspecting crowd that were locked in an auditorium.

I stopped reading when I saw those idiotic words “climate change.” Left-wing BS.

The chillers don’t really have runoff. The cooling towers associated with the HVAC water chillers, do. That blowdown water typically goes to the municipal sewage system.

“As an aside, they don’t seem to like the way I taste. People around me can be being eaten alive by mosquitos, but they hardly touch me.”

The itching from mosquito bites is basically an allergic reaction. They’re biting you, you’re just not allergic to them. At least that’s what I read somewhere.

Long time since I laid eyes on a system. There was always a redundant drain system. They will get dirty and hold runoff in places. Doesn’t take much.

I think it is now in all of the media’s writer’s style guide. Goebbels would be proud.

**Wet grass?... In Las Vegas????**

Over 50 golf courses in the LV metro. They get watered. Lotta grass, and water traps.

When dengue fever or whatever breaks out because of all the immigrants, they will need something to blame it on.

It would be simply urban development .
Building houses with green lawns in the desert is the only factor.

I’m one of the tasty people. When I was young and living in an area with a few mosquitos I woke up one morning with over 50 bites. My roommate had none.

That may be so, but if I'm getting bitten, in addition to not getting itchy, I don't even have red spots or bumps where they might have bit me.

I have occasionally gotten a mosquito bite (and they do itch), but nothing like people around me that are getting devoured by them. A few years back I often worked with a girl on fireworks shoots on hot summer evenings when the mosquitos were just swarming over the grassy fields. She would just be bit all over even with repellent and I'd end the night unscathed without it.
