AMES, Iowa -- Asian tiger mosquitoes are spreading into the Midwest, with confirmed populations in Iowa, Illinois and Missouri. The insect's also been caught in traps in Wisconsin and Nebraska.
"This is not native here, because of that it is also a nuisance. It tends to feed on humans and can be aggressive in its behavior in trying to bite us," says Iowa State University Entomologist Ryan Smith.
He says the Asian tiger mosquito is different from the other kinds of mosquitoes we're used to a couple of other notable ways.
"This is a lot different--these mosquitoes are active and about flying during the daytime. In the middle of the day if you're out mowing the lawn or whatever it may be, you do have the potential to be bitten at that time," Smith says.
The mosquitoes most common in the Midwest are typically active at dusk and at dawn.
He also says the Asian tiger mosquitoes, or at least their eggs, also seem to be capable of withstanding Midwest winters.
"We do have freezing conditions that are consistent during the wintertime, and that was always thought to be a somewhat of a barrier to them to be introduced and survive in this area--and they are able to do it," Smith says.
He says the Asian tiger mosquito can carry Zika and other viruses, which can all cause serious health problems in humans.
“Just be aware that they’re here, and they have the potential to spread. Pay attention to neglected materials in the yard that could allow them to lay eggs,” Smith says.
The Asian tiger mosquito has spread into 26 U.S. states says since first being detected in Texas in 1985.
