Sasha CampbellPlant-eating stink bugs cause damage to plants by sucking and feeding on the plants. Though there is no need to fear these insects, in some cases, they can cause significant damage to your crops.
You may find them in your garden on tomatoes, corn, green peppers, beans, and other vegetables. Some stink bugs may also enter your home in the cooler months for warmth and shelter.
Therefore, please make every effort to control them as best as possible.
Identification
The stink bug acquired its name because of its unpleasant odor when disturbed or threatened.
Some say it smells like cilantro; others say it smells like burned tires. However, these insects’ unpleasant odor is supposedly a defense mechanism against predators [2].
Depending on the species, the adult bugs might be green, grayish, or brown.

However, don’t mix up stink bugs with common squash pests. If you see insects on your cucumber plants, pumpkins, or squash, those are likely squash bugs on your plants.
