This stink bug emerges in spring and can produce five generations annually in warm weather. The Brown Marmorated Stink Bug’s habitat includes gardens, parks, and agricultural fields.
This species eats over 100 plants such as ornamental fruits and vegetable crops. They will eat the juice of the fruits and veggies. These stink bugs cause pitting and scarring of the fruit, and also introduce microorganisms that cause decay.
Then in the fall, this stink bug seeks shelter from the cold weather.
Up to hundreds will seek refuge indoors and can become a massive nuisance. They look for openings, such as gaps in vents, windows, and doors.
But don’t worry, the Brown Marmorated Stink Bug doesn’t bite people or pets, and they don’t spread disease. But be careful not to pick them up or squash them because they will release their stink spray with a nasty odor.
