The brown stink bug (BMSB) is classified as an invasive species or a pest of foreign origin. It's also known as the East Asian stink insect or yellow-brown stink bug. There are various ways to describe stink bugs. "Large, oval-shaped insects" and "shield-shaped insects" are two terms used to describe them. Adult stink bugs can grow to be over 2 cm long. They're almost as long as they are wide. Because their legs protrude from the sides, the mature bugs look more significant. A brownish stink bug is the brown marmorated stink insect. The antennae have lighter bands, whereas the wings have darker bands.
Stink bugs, known for their "smelly" reputation, infiltrate houses in search of a comfortable location to overwinter during the cooler months. Adult stink bugs can fly well and land by folding their wings on top of their bodies. Nymphs' wings aren't fully grown. When the nymph matures into an adult, the wings emerge.
Stink bugs are commonly seen inside homes throughout the late summer and fall months when the temperatures outside begin to cool. Their presence can be identified by the presence of vast numbers of living or dead stink bugs. They congregate on the sunny sides of houses to warm themselves up.
Although the brown marmorated stink bug does not sting and is unlikely to bite, care should be taken when handling them to prevent them from emitting their noxious stench. While stink bugs do not represent a health or property concern to homes, they may rapidly become an odor-producing nuisance. The majority of stink bug species eat plants. They drink the juice from plant leaves, stems, and roots. They prey on beautiful plants as well as weeds.
Spend some time inspecting the outside of your home for easy access points for stink bugs. Pay special attention to the areas around siding and utility pipes, behind chimneys, and beneath wood fascia or other openings. Use a good grade silicone or silicone-latex caulk to seal any cracks or holes that you find. Check for ripped weather-stripping and loose mortar as well. If necessary, door sweeps can also be installed. Because lights attract stink bugs, it's best to keep outside illumination to a minimum.
