(Radio Iowa) – It has been too cool and dry for mosquitoes to get very active so far this year — but you may have noticed another insect flying around. I-S-U entomologist, Donald Stewart, says wasps have been active. “Most of these are paper wasps with an elongated, about an in long, brownish color. It’s the wasp that makes a nest up under the eaves of your house. It looks like a little upside down umbrella hanging there,” Lewis says. He says the wasps right now are looking for a place to live.

“Those nests are started by a single queen,” Lewis explains,”and they are quite active on the warm days of spring as they look for a sheltered location where they can build that nest.” But Lewis says they shouldn’t be very aggressive. “They aren’t interested in stinging, they’re interested in finding a place to make a nest — build a little nest, catch a little food, lay a few eggs,” according to Lewis. “Later in the summer when the population increases, then the wasps will be a little bit more aggressive, but right now they are not quite as threatening as people expect.”

Lewis says they shouldn’t pose much of a concern.
