Stink bugs, formally known as Halyomorpha halys, are a species of insects that have become increasingly common in North America over the past few decades. These bugs are known for their distinctive odor and for the damage they can cause to crops and gardens. Despite their prevalence, there are still many myths and misconceptions about stink bugs that persist. In this article, we’ll explore some of these myths and separate fact from fiction.

Myth #1: Stink Bugs Only Eat Plants

One of the most persistent myths about stink bugs is that they only eat plants. While it’s true that stink bugs are primarily herbivorous and do feed on a wide variety of plants, they are also known to eat other insects. In fact, stink bugs are considered to be generalist predators, meaning they will eat whatever prey is available to them.

Stink bugs have been observed eating caterpillars, beetles, flies, and even other stink bugs. In some cases, stink bugs have been found to be an effective natural control for pest insects in agricultural settings. However, it’s important to note that stink bugs can also feed on beneficial insects like bees and ladybugs.

Myth #2: Stink Bugs Are Harmless

While stink bugs may not pose a direct threat to humans or pets, they can still cause significant damage to crops and gardens. Stink bugs use their piercing-sucking mouthparts to feed on plants, causing wilting, discoloration, and deformities in fruits and vegetables.

In addition to their feeding habits, stink bugs can also release a pungent odor when threatened or disturbed. This odor is a defense mechanism that can deter predators but can also be unpleasant for humans. Some people may even experience an allergic reaction to the odor or to the bug itself.

Myth #3: Stink Bugs Are Native to North America

Stink bugs are actually native to East Asia and were first introduced to the United States in the late 1990s. It’s believed that stink bugs were brought over to the U.S. accidentally via shipping containers or other means of transport.

Since their introduction, stink bugs have spread rapidly throughout North America and have become a significant agricultural pest in many regions. Due to their ability to reproduce quickly and their lack of natural predators in North America, stink bugs can be difficult to control once they become established in an area.

Myth #4: Stink Bugs Are Easy to Get Rid Of

Unfortunately, getting rid of stink bugs can be easier said than done. While there are a number of DIY methods that people swear by – such as vacuuming them up or using sticky traps – these methods are often ineffective in the long term. In fact, some experts warn that using vacuum cleaners to remove stink bugs can actually make the problem worse by releasing more of the odor into the air.

The most effective way to control stink bugs is through a combination of preventative measures and professional pest control services. This may involve sealing up cracks and gaps around windows and doors, removing any potential food sources like fallen fruit or vegetables, and spraying insecticides in problem areas.

Myth #5: Stink Bugs Can’t Survive Cold Temperatures

While it’s true that stink bugs are not well-suited to cold temperatures, they are able to survive through the winter months by finding shelter in warm areas like homes or other buildings. When stink bugs enter a home or other structure, they can be difficult to remove without professional assistance.

In addition to being a nuisance inside homes, stink bugs can also cause damage to insulation and other materials if left unchecked. It’s important to take steps to prevent stink bugs from entering your home in the first place, such as sealing up cracks and gaps around windows and doors and using screens on all openings.


Stink bugs may be a common sight in many parts of North America, but there are still many myths and misconceptions surrounding these insects. By understanding the true nature of stink bugs – including their feeding habits, origin, and behavior – we can take steps to control their populations and minimize the damage they cause. Whether you’re a homeowner or an agricultural professional, it’s important to stay informed about stink bugs and to seek professional assistance if you’re dealing with an infestation.
