It will probably carry life-threatening illnesses. It’s troublesome to seek out and arduous to kill. And it’s obsessive about human blood.
The Aedes aegypti is a species of mosquito that individuals like Tim Moore, district supervisor of a mosquito management district on the Western Slope of Colorado, actually don’t need to see.

It’s popping up everywhere in the Mountain West, the place circumstances have traditionally been far too harsh for it to outlive. Within the final decade, cities in New Mexico and Utah have begun catching Aedes aegypti of their traps yr after yr, and simply this summer time, one was discovered for the first time in Idaho.
Now, an previous residential neighborhood in Grand Junction, Colorado, has emerged as one of many newest frontiers for this troublesome mosquito.
Town, with a inhabitants of about 70,000, is the most important in Colorado west of the Continental Divide. In 2019, the native mosquito management district noticed one wayward Aedes aegypti in a lure. It was odd, however the mosquitoes had already been present in Moab, Utah, about 100 miles to the southwest. Moore, the district supervisor, figured they’d caught a hitchhiker and that the cruel Colorado local weather would shortly eradicate the species.
“I concluded it was a one-off, and we don’t have to fret an excessive amount of about this,” Moore mentioned.
