Why You Should Never Squish a Stink Bug
Commit the insect you see above to memory. That’s the brown marmorated stink bug, an invasive species originally from Asia that’s made inroads across large sections of the United States, including the Mid-Atlantic.
If you come across one, don’t squish it. In fact, don’t even nudge it. A stink bug’s pestilence can survive after death. And you can probably guess how.
According to The State, stink bugs release a secretion that smells absolutely awful when they’re disturbed or feel threatened. Stomping them just expedites the liquid. Those who have had the unfortunate opportunity to get a whiff have described it as resembling skunk odor or rotten cilantro.
In winter, the bugs tend to find their way indoors, where their half-inch bodies tend to catch the eye of homeowners. Fortunately, they’re largely harmless, and are not known to carry diseases or be destructive to pets or property. (Crops are an exception: The stinkbugs can prove damaging to agriculture.) While exterminators can treat houses, some recommend just ignoring them.
If you want a DIY approach, you can try vacuuming them up or leaving out trays with soapy water. The mixture will kill the bugs and minimize any post-mortem secretion.
Since the bugs were first spotted in Allentown, Pennsylvania around 1998, they’ve been spotted in 43 states. Generally, you probably won’t see more than a few in your home, though they’ll definitely congregate if conditions are right. One wildlife biologist in Maryland suffering from an infestation counted 26,000 stink bugs in his residence.
The good news? Scientists have determined that the stinkbug’s natural predator, the samurai wasp, is in hot pursuit. Entomologists at the U.S. Department of Agriculture had made plans to bring the wasp over from Asia to help control the bug population but discovered in 2014 that the wasp had somehow made the journey on its own. Their idea of population control is injecting their own eggs into a stinkbug’s, its larvae eating the pest. The parasitic wasp is in 10 states and climbing.
