Nebraska’s first human case of mosquito-borne West Nile virus for the 2023 season has been identified in the Three Rivers Public Health District, which covers Dodge, Saunders and Washington Counties.

The truth about mosquitoes — and what you may be doing wrong
Is it really a bad year for mosquitoes?
"For lot of people, it feels like this year is a lot worse," Carlson said, who says on average the levels are similar to those seen in 2019 and 2020. "Last year, there were almost no mosquitoes for pretty much the duration of the entire summer because of the drought."
That said, some areas are experiencing above-average mosquito populations this year because of heavier rain or higher water levels, he added. So if you live in a part of the state that has been wetter than usual, it could be that the mosquitoes are indeed back with a vengeance.
Is my suffering worse than yours?
My dad used to console me by saying mosquitoes couldn't resist my "sweet blood." Carlson says people like me have "won the genetic lottery." Fact is, some people are more attractive to mosquitoes because of their underlying biology — the amounts of carbon dioxide they emit or the natural scents they carry, for example.
Some of it can be activity-based, Aliota adds. If you're huffing and puffing on a strenuous hike, you might feel them coming for you. Potential bummer alert for your July 4th gathering: Alcohol consumption can also stimulate mosquito attraction.
They also detect us by body heat. So if your body temperature naturally runs warmer than the average person, consider yourself desirable.
"That's why if you're ever around a pregnant woman in the summertime, she tends to get more mosquito bites than anybody else," Carlson said.
So the solution is clear: Invite a pregnant friend to your barbecue.
Should I eat garlic?
"I think you'd have to eat a lot of garlic to have any kind of repellent effect," Aliota said.
Same goes for those citronella candles — or planting citronella, said Carlson. "Your yard has to be entirely made out of citronella plants for it to have any impact."
Silver linings
Sometimes it's easy to lose sight of the fact that in other parts of the world, "mosquitoes are Public Health Enemy No. 1," said Aliota.
Even in the Midwest, cases of West Nile Virus pop up every summer. But our cold winters are good for something, he adds. The species that transmit the pathogens that cause dengue or Zika virus aren't established in our state.
What's the 2022 mosquito forecast?
"Predicting what the rest of the summer is going to be like for mosquitoes is essentially like predicting the weather," Aliota said. "It's somewhat unreliable, and it can vary depending on the mosquito species."
Although more than 50 mosquito species are found in the Midwest, the ones that are most likely biting you in your yard are aedes vexans. They lay their eggs in tree holes or other containers that collect water and thrive when there are intermittent thunderstorms. This species is the most likely to peak at this time of year.
