You’ll likely notice fewer of those troublemaking, invasive stink bugs this years.
“Many of the natural enemies, many of our indigenous predators and parasites, have actually caught up with these guys now and are having a major impact on their population,” said University of Maryland entomology professor Mike Raupp.
“It’s kind of like ‘War of the Worlds,’ where the little microbes defeated the alien.”
Many different insects target stink bugs,
“We found some of the tiny parasitic wasps that attack their eggs have moved over from our native stink bugs and are now stinging and killing the eggs of the brown marmorated stink bug,”
The average person is likely more familiar with another stink bug predator — the Chinese praying mantis.
“That big beautiful praying mantis that you find in your garden … it loves to eat stink bugs,”
This particular mantis and the invasive stink bug are both originally from Asia.
“The Chinese praying mantis was introduced to the U.S. in about the 1860s [or] 1890s in Pennsylvania,”
“Less than 40 miles away a century later, the brown marmorated stink bug showed up in Allentown. So this is simply a matter of a predator having an old friend over for dinner.”
According to Raupp, populations of brown marmorated stink bugs have been declining in the D.C. region for several years.
“I think our indigenous good guys here have put the beat down on stink bugs, and I think homeowners and gardeners will enjoy better vegetables and fewer stink bug problems in their gardens this year,”
