Starting from the fall, stink bugs will seek shelter within artificial structures for overwintering. As such, stink bug infestations in homes are common during winter.

Who do stink bugs live with?

The adult brown marmorated stink bug is considered a solitary insect. However, it is possible to find these bugs in clusters due to more practical reasons like, during the matings season, in overwintering sites, in feeding sites, and as groups of young or newborn nymphs.

How long does a stink bug live?

Stink bugs live for an average of six to eight months. However, under suitable environmental conditions, some stink bug species can have a lifespan of almost a year. In the cool temperate zones, the stink bugs can produce one successful generation every year. However, warmer climates can influence the production of two to six generations every year.

How do they reproduce?

The brown marmorated stink bugs become active from March through to September. The male bug courts its mate by releasing pheromones and signals in the form of vibrations.

Why are they called stink bugs?

The term 'stink bug' is an American English name, specifically for the bugs within the Pentatomidade family of insects. The name is a reference to the unpleasant odor released from the holes in the abdomen of these bugs.

Whenever a stink bug feels the threat of predators or is disturbed, it releases this pungent spray as a defense mechanism. Accidentally or purposely crushing the insect will also release this odor.

How to get rid of stink bugs?

House maintenance during the fall is best to prevent or reduce stink bug infestation in homes since the bugs are looking for overwintering sites during that season.

They crawl into houses to protect themselves from the cold weather outdoors. For any stink bug in the house, you can install sticky traps in corners and enclosed areas to catch the bugs and later release them outside.

Avoid crushing them or using a vacuum cleaner to get rid of this invasive species of bugs to avoid spreading the unpleasant odor inside your house.

You can also call in a pest control professional during the late summer or fall to treat your home for stink bug infestation. Chemical control within homes should be avoided.

The key threat of stink bugs is however related to them being a major agricultural pest. Many stink bug species are also resistant to several pesticides, requiring different control measures to prevent crop damage.

Many insecticides are also ineffective, while most are used for keeping the bugs away from crop fields instead of killing them. One of the best methods for controlling stink bug feeding in crop fields seems to be through the introduction of predators like birds, wasps, and spiders.

More focused efforts from the state and national governments can also help in curbing stink bug infestations.

Investments and research in biological control programs can influence the development of new control measures. While there are few effective pesticides used to get rid of stink bugs, it is important to note that pesticides are poisonous and must be handled with care.
