COLUMBUS, Ohio (WTVN) -- Ohio is seeing an increase in shield-shaped bugs and it's causing quite a...well, stink. The marmorated Asian stink bug first got into Ohio about 4 years ago. Since then it's been multiplying to the point where we're now starting to see more of them in our homes.

"They're really not causing any damage to your house nor are they going to cause any problems for you in terms of biting or anything like that," said Ohio State University entomologist Ron Hammond.

The bugs tend to feed to plants and crops during the summer then about this time of year start looking for a place to spend the winter.

"It just so happens that one of their favorite places are our homes," he said.

The pests likely came to America on a ship from Asia. They are larger than the native stink bugs.

To get rid of them, Hammond suggests just simply snagging them in a plastic bag and either sealing it up until they die or tossing it in the freezer. Whatever you do don't smash them!

"They are called stink bugs for a reason and the do release an odor for defensive purposes."

If you opt for a vacuum cleaner he recommends emptying the bag or canister immediately.

Most of the calls about the bugs are coming from urban areas, according to Hammond.
