What Eats Stink Bugs: Discover Their Natural Predators

Stink bugs may be a nuisance to many due to their unpleasant odor, but they play a vital role in the ecosystem as a food source for various predators. In this article, we will explore the diverse range of creatures that feed on stink bugs and the ways in which they help control stink bug populations.

You might be surprised to learn that a number of birds, insects, and even spiders consider stink bugs a tasty snack. From the sneaky attacks of assassin bugs to the brutish pecks of a blue jay, these predators are more than happy to feast on these odorous insects. Let’s take a closer look at some standout examples of stink bug predators and how they manage to subdue their smelly prey.

Understanding Stink Bugs

Stink bugs are a type of insect known for their distinct odor, which they release as a defense mechanism against predators. These bugs come in various species and colors, with the brown marmorated stink bug (BMSB) and the green stink bug being quite common.

The brown marmorated stink bug is shield-shaped and measures between 14 and 17 mm long, roughly the size of a U.S. dime. Its abdomen and antennal segments feature alternating broad light and dark bands. Adult females lay clusters of 20-30 light green or yellow, elliptical-shaped eggs between May and August.

On the other hand, the green stink bug belongs to the Pentatomidae family. It is a major pest in cotton, rice, and soybean fields and releases an offensive odor when handled, just like its brown counterpart.

Generally, stink bugs have some shared characteristics:

• Shield-shaped body
• Unpleasant odor when disturbed
• Variety of species and colors

While some species of stink bugs are harmful to crops, others can be beneficial to gardeners. For example, predatory stink bugs feed on over 100 species of insect pests, helping to control their populations.

Remember, understanding the differences between stink bug species is essential because some pose risks to your garden or crops, while others prove helpful in pest control.

Feeding Behavior of Stink Bugs

Stink bugs are known for their diverse diet, as they feed on various parts of plants, including the fruit, leaves, and stems. Here’s a brief overview of stink bug feeding habits, centering on their preferred plants and fruits.

When feasting on plants, you might find stink bugs targeting:

• Corn
• Beans
• Tomatoes
• Sunflower

For fruit lovers, stink bugs are known to feed on:

• Apples
• Berries
• Peaches
• Pears

Their feeding method involves piercing the plant or fruit with their straw-like mouthparts, followed by consuming the sap or juices. This causes damage to the plant or fruit, leaving scars, marks, or even creating openings for other pests and microbes.

Stink bugs lay their eggs on the plant leaves and their nymphs will feed on the same plants as they develop.

Here’s a comparison table to help you further understand their feeding preferences:

In summary, stink bugs are not picky eaters and their diet mainly consists of plant leaves and various fruits. They cause damage to plants and fruits, affecting their appearance, and allowing other pests or pathogens to enter.

Habitat and Hibernation

In the fall, stink bugs search for warm places to spend winter. They often find their way into your home, seeking the warmth and protection it offers. If you’re wondering where these pests venture during spring, they’re likely to be found in gardens around the United States and beyond.

When hibernating, stink bugs typically seek refuge in tight spaces such as cracks and crevices in walls, window frames, and beneath sidings. A popular spot for them is near cedar trees, allowing them to stay sheltered during the colder months. In your home, they might hide in attics, crawl spaces, and even between walls.

In spring, as temperatures rise and warmth returns, stink bugs exit their hiding spots and become more active. You’ll likely encounter them in your garden, feasting on various plants and fruits. To keep these pests at bay, follow these simple guidelines:

• Inspect your home in fall for gaps and cracks where stink bugs could enter.
• Seal any openings you find with caulk or draft stoppers.
• Keep cedar trees well-trimmed and away from your home’s structure.
• Maintain a clean and well-tended garden to reduce potential hiding spots.

By understanding the habitats and hibernation patterns of stink bugs, you can make well-informed decisions on how to best protect your home and garden from these persistent pests.

Signs of Stink Bug Infestation

Stink bugs can cause significant damage to your crops and become a nuisance in your home. Knowing the signs of their infestation is crucial in order to protect your plants and maintain a comfortable living space.

Damaged Crops

• Stink bugs mainly feed on fruits and vegetables, causing irregular scarring on their surface.
• Their feeding leaves behind a distinctive scar that resembles a series of concentric circles, known as the “cat-facing” injury.

Infestation in Orchards

• You might notice these pests clinging to the bark of trees in your orchard.
• They can cause extensive damage to fruit crops like apples and peaches.

Home Invasion

• As temperatures drop, stink bugs tend to seek shelter in homes.
• Watch out for these insects gathering around windows, doors, or cracks in your house.

Odor

• The smell of stink bugs can be an indicator of their presence.
• If you notice a strong, unpleasant odor in your home or garden, it could be a sign of an infestation.

To prevent further damage, it’s important to act fast if you suspect a stink bug infestation. Investigate the affected areas and consider seeking professional help if necessary. Remember to remain vigilant for these insects, especially during the growing season, to keep your crops and home stink bug-free.

Common Stink Bug Predators

In your garden, stink bugs can be quite a nuisance. Luckily, there are several natural stink bug predators to keep their population in check. Some of the common predators include:

• Ants: These tiny insects may be small, but they don’t shy away from tackling a stink bug. They can often be seen dragging stink bugs back to their colony.
• Birds: Many bird species, such as bluebirds and woodpeckers, enjoy feeding on stink bugs.
• Spiders: These eight-legged creatures are known to weave their webs and trap stink bugs, consuming them for a meal.

In addition to these common predators, there are other specialized insects that feed on stink bugs as well:

• Predatory stink bugs: Unlike the bothersome brown marmorated stink bugs, these species of stink bugs are a gardener’s friend. They feed on over 100 species of pest insects, including their pest-relatives.
• Wasps: Some wasps, particularly parasitoid wasps, lay their eggs on stink bug eggs or nymphs. When the eggs hatch, the wasp larvae consume the stink bug, eventually killing it.

In summary, nature has provided various stink bug predators that help to control their population. Encouraging the presence of these predators in your garden can be an excellent way to keep stink bugs at bay. Remember, though, not all predators are suitable for all environments. Make sure to consider which predators will best work with your garden’s ecosystem to maintain a healthy balance.
