What Attracts Japanese Stink Bugs?

Stink bugs are harmless but annoying pests that feed on various crops and plants, including soybeans, trees, fruits, and vegetables found inside homes. They are most attracted to overripe, damaged, or decaying fruit and vegetation. Stink bugs are phototrophic insects, meaning they need a warm place to overwinter. They are native to Japan, China, Korea, and Taiwan, and have spread across the United States since the late 90s.

Stink bugs are attracted to light and warmth in homes, especially during cooler fall and winter months. They also seek food sources, such as fruit and vegetables, which can draw them to outdoor vegetation. They gain entry into structures through cracks, crevices, gaps, holes in foundations, window and door frames, soffits, attics, and underneath siding.

Stink bugs emit a pungent odor from their underside, best described as a coriander stink bomb. They typically eat plants, preferring fruit trees over most other things. Brown Marmorated Stink Bugs (BMSBs) are brown, smelly, and suck on plants. When a BMSB finds a suitable winter shelter, it secretes a chemical odor that attracts other stink bugs. Killing a stink bug does not attract them. Stink bugs produce a foul smell when threatened, a mechanism thought to help ward off predators. They are also called shield bugs.

To get rid of Japanese stink bugs infesting your plants, drape lightweight row covers over your garden plants. This can help save highly desirable crops like late-season tomatoes.

Do Stink Bugs Eat Soybeans?

Originating from the forests of Japan, China, Korea, and Taiwan, stink bugs made their way to the United States in the late 1990s, quickly becoming a familiar sight in many households. While they have little interest in humans, stink bugs pose a threat to agriculture, particularly soybeans, as they feed on fruits and crops. Various species exist in the U. S., with the green stink bug (Acrosternum hilare) being the most prevalent, alongside brown stink bugs (Euschistus spp.) that also target soybean pods and seeds.

Using their piercing mouthparts, stink bugs extract plant fluids while injecting saliva, which can damage the plant's surfaces and contribute to decay. This feeding behavior leads to direct harm to soybean crops during their development.
