You’ll know ’em by their smell: stink bugs are here

For one thing, they are aptly named.

Residents who casually squash a halyomorpha halys underfoot will be assaulted by a sharp odor coming from the deceased marmorated (marbled) stink bug.

The smelly critters are here, with some people saying their houses are full of them: climbing walls, underfoot (careful) and hanging out in window curtains and drapes. “Everyone’s asking me about stink bugs,” said Wally Ogar of East End Pest Control on Shelter Island. “I’ve got them in my house, too.”

He’s not the only one. Joanne Sherman said she had never seen one until this spring, and there was no trace of them this summer. But just recently they were back. Neighbors, Ms. Sherman said, told her their house is covered with the bugs.

Mr. Ogar said it’s not a new phenomenon, but happens every fall when the bugs, ready to hibernate, make their way into houses.

But Craig Rosenberg of North Shore Exterminating in Southold said stink bugs are relatively new residents of the East End.

Daniel Gilrein, an entomologist with Cornell Cooperative Extension of Suffolk County, said “there had been low numbers of stink bugs recorded over the last several years,” but that he and his colleagues “have seen more this year than previously.”

Mr. Gilrein added that he had about 15 in his Riverhead house last week.

Stink bugs might smell bad if roughed up, but they don’t bite and won’t hurt pets or do any structural damage. They’re unsightly and can be a nuisance in large numbers, the entomologist said. Stink bugs are not so benign to farms, orchards or gardens, however, feeding on fruits and leaves.

The jury is still out on getting rid of them, according to Mr. Rosenberg, who is cautious about using insecticides in homes without more information. He’s consulted with Mr. Gilrein and other entomologists and is waiting for upcoming seminars that will address a stink bug solution.

Mr. Rosenberg and Mr. Ogar said some insecticides can be put down outside houses near foundation lines, and Mr. Rosenberg has used “fly lights” in attics, which attracts the bugs and then captures them.

They can be vacuumed, Mr. Ogar said, but the bag has to be thrown away immediately. What should you do if you’re sharing quarters with stink bugs?

Mr. Gilrein advised making sure all possible entry points are sealed or screened off, but admitted this could be impossible for older homes.

“Over the next few years the population may be building, so if that’s the case and they become a serious annoyance, you might contact a pest control professional for assistance,” he added.

What shouldn’t you do if you’ve got stink bugs in the house?

“Panic,” Mr. Gilrein said.
