Fenton Township (WJRT) - (9/25/17) - They're starting to show up everywhere, in homes, businesses and even orchards. We're talking about an invasive species of stink bugs. They're begining to damage the Mid-Michigan apple crop.
Brown marmorated stink bugs aren't only nuisances, they can damage crops. Spots on apples can be caused by stink bugs. They're natives of Asia. They came to the US in the 1990s and a few years ago caused a lot of damage to crops in New Jersey and Pennsylvania.
In some Mid-Michigan orchards, workers will be spraying a pesticide to kill off stink bugs before they do serious damage.
MSU Extension has set up sticky traps on the edges of orchards to get an idea of the magnitude of the population.
"When the brown marmorated stink bugs land on the trap, they're stuck," said Bob Tritten, MSU extension horticulturist.
25 were stuck to the trap this week. The brown marmorated stink bugs are looking for a place to spend the winter.
"In the fall when it begins to get cool, they like to aggregate in attics, unheated buildings and underneath siding," said Tritten.
While they don't bite or sting, they can be a pest in another way.
"They're called stink bugs for a distinct reason. When you crush them there's an odor, it stinks," said Tritten.
And it's likely if you see them this fall, they'll probably be house guests for a few months.
"People are going to be seeing them on their window ledges on warm winter days for example," said Tritten.
