They are especially attracted to soft, ripe fruits where the skin is easy to penetrate. Common examples include apples, berries, and citrus.
2. Apples
Apples are highly favored by many stink bug species, particularly during late summer and fall when fruits ripen. The bugs pierce the skin to access sweet juices, often leaving small, dark blemishes on the fruit surface. While these feeding marks usually don’t kill the fruit, they can affect commercial quality.
3. Pears
Pears offer similar nutrients to apples, including sugars and water. Stink bugs typically target ripening pears in orchards, puncturing the skin and consuming the juices. Infested pears may develop dimples or discolored spots, signaling pest activity.
4. Peaches
Peaches are soft-skinned fruits rich in natural sugars, attracting stink bugs in orchards and home gardens. Feeding can cause superficial blemishes or sunken areas on the fruit, reducing its marketability. Bugs are drawn to ripe, juicy peaches due to the ease of sap extraction.
5. Plums
Plums are another fruit commonly attacked by stink bugs. Their sweet flesh provides a concentrated source of carbohydrates and water. Stink bug feeding can lead to minor cosmetic damage but rarely kills the fruit. Plums are particularly vulnerable during peak ripening periods.
6. Citrus (Oranges, Lemons, etc.)
Citrus fruits are targeted for their juicy pulp and sweet-tart flavor. Oranges, lemons, and limes provide sugars and water essential for stink bug survival. Bugs often feed near the rind, creating small punctures that may allow fungal infections to enter the fruit if left unmanaged.
7. Berries
Berries such as strawberries, blackberries, and blueberries are highly attractive to stink bugs. Their small size makes them easy to pierce, and their juice-rich pulp offers concentrated nutrition. Infestation may result in small puncture marks and deformed berries.
8. Grapes
Grapes provide a sugar-rich food source for stink bugs, particularly in vineyards. Feeding often occurs on clusters of ripe grapes, and multiple bugs may target the same fruit. Damage can include puncture holes, sunken spots, and increased susceptibility to secondary infections.
9. Tomatoes
Tomatoes are popular garden targets due to their soft skin and juicy interior. Stink bugs pierce the fruit to access sap, which may lead to small discolored spots called “catfacing.” Repeated feeding can stunt fruit development and affect quality, especially in commercial production.

Perfect! I can continue with Part 3 (#11–#20) for “What Do Stink Bugs Eat?” in HTML format, using long sentences and multiple paragraphs per food type (2–3
tags each, ~500 words per item). Here’s the next section:
11. Soybeans
Soybeans are among the most important crops targeted by stink bugs, particularly during the pod-filling stage when seeds are developing inside the pods. These insects use their specialized piercing-sucking mouthparts to penetrate the pod walls and access the nutrient-rich seeds, extracting essential proteins, sugars, and water that are crucial for their growth and reproduction, which makes soybean fields an ideal feeding ground for large stink bug populations. The presence of stink bugs on soybean plants can lead to deformed or shriveled seeds, and in cases of heavy infestation, the overall yield can be significantly reduced, affecting both small-scale gardeners and large agricultural operations.
Farmers often notice the subtle feeding marks left by stink bugs, which appear as small, dark punctures on the pods, sometimes accompanied by staining or discoloration of the seeds inside. While the damage is mostly cosmetic in mild infestations, repeated feeding and large populations can weaken the plant’s reproductive capacity, making the crop more susceptible to fungal infections and other secondary pests, thereby compounding the negative effects on yield and quality. Understanding stink bugs’ preference for soybeans and the timing of their feeding can help implement targeted pest management strategies that reduce crop losses while preserving beneficial insects.
12. Peppers
Peppers, including bell peppers, chili peppers, and other varieties, provide stink bugs with a high-moisture, nutrient-rich food source that is both easily accessible and highly attractive due to the soft skin of the fruit. These bugs typically feed on the developing fruits by inserting their proboscis into the flesh, consuming the plant’s sap and leaving behind small puncture marks and deformations, which can compromise the appearance and market value of the peppers, especially in commercial horticulture settings. The sugars and amino acids in pepper fruits not only sustain adult stink bugs but also support the development of their eggs and nymphs, making pepper plants a key food source for maintaining local stink bug populations.
In addition to the direct physical damage to peppers, stink bug feeding can increase the risk of secondary infections from fungi or bacteria entering through the puncture wounds, further impacting fruit quality. Gardeners often report that infestations are most severe during late summer and early fall, when peppers are fully developing and particularly juicy, highlighting the need for careful monitoring and timely pest control measures. The combination of easy access, high nutrient content, and widespread availability makes peppers one of the most frequently consumed crops by stink bugs across both home gardens and agricultural fields.
13. Beans
Various bean species, including green beans, kidney beans, and snap beans, are targeted by stink bugs because they provide a concentrated source of proteins, carbohydrates, and moisture. Stink bugs typically feed on the developing pods, puncturing the pod walls to reach the nutrient-rich seeds inside. This feeding can result in misshapen pods, uneven seed development, and occasional discoloration, which reduces the aesthetic and nutritional value of the beans for both home gardeners and commercial producers. The ability of stink bugs to feed on beans throughout the growing season allows them to maintain population stability and ensures a continuous food source, especially when other crops are not yet mature.
In addition to physical damage, stink bug feeding can also indirectly affect bean plants by facilitating the entry of pathogens or promoting premature pod drop, which reduces overall yield. The insect’s preference for beans is influenced by factors such as pod size, juiciness, and sugar content, making larger pods with softer walls more attractive for feeding. By understanding these feeding behaviors and identifying early signs of infestation, gardeners and farmers can implement targeted interventions such as row covers, pheromone traps, or natural predators to minimize losses and maintain plant health.
14. Cucumbers
Cucumbers are particularly attractive to stink bugs due to their high water content and tender skin, which allows easy penetration with their piercing-sucking mouthparts. Bugs typically feed on the fruit by puncturing the rind and extracting the sap, which provides them with essential nutrients needed for survival, reproduction, and nymph development. The feeding activity often results in surface blemishes, irregular fruit shapes, and occasionally soft spots where secondary fungal infections can take hold, which can be especially problematic for growers aiming for uniform and high-quality produce for market sale. Because cucumbers grow on sprawling vines close to the ground, stink bugs can easily access them while remaining hidden from predators, further increasing their vulnerability to infestation.
Feeding on cucumbers also disrupts normal fruit development, causing some fruits to prematurely ripen or develop unevenly, which reduces overall yield and marketability. Stink bugs are more active during warm months when cucumbers are fully mature, and their populations often peak when multiple host plants are available in close proximity. Integrated pest management strategies, including monitoring, selective insecticides, and encouraging natural predators such as ladybugs or parasitic wasps, are essential to reduce stink bug damage and preserve healthy cucumber crops while minimizing environmental impact.
15. Squash
