Stink Bugs Overview
Stink bugs are a group of insects known for the unpleasant smell they emit when disturbed or threatened. The brown marmorated stink bug is one of the most common species found in North America, and it poses a significant problem for homeowners due to its tendency to infest buildings during colder months. These bugs are typically black or brown and have a shield-shaped body with an elongated antennae.
Stink bugs can cause damage to crops, as they feed on various plants and fruits. Although they are not directly harmful to humans, their presence can be a nuisance due to their foul odor. This smell is emitted as a defense mechanism from specialized glands located on the underside of their bodies.
An infestation of brown marmorated stink bugs can be challenging to control as they are resistant to many insecticides. Moreover, their discreet nature and ability to enter buildings through small gaps make them difficult to eradicate completely.
Controlling an infestation can be challenging, but understanding their characteristics and behaviors can aid in stink bug management.

Attracting Birds to Control Stink Bugs
Creating a bird-friendly backyard can be an effective way to control stink bug populations in your home and garden. By providing an appealing habitat with native plants, bird feeders, and fruit trees, you can attract birds that naturally feed on these pesky insects.
Step 1: Plant Native Plants
To begin, planting native plants in your yard can help create a thriving ecosystem for birds and their prey. These plants attract a variety of insects, including stink bugs, which in turn entice insect-eating birds like bluebirds, wrens, and sparrows to visit your garden. This will not only help manage stink bug populations but also support local bird species.
Step 2: Use Bird Feeders
Setting up bird feeders is another great way to attract birds to your yard. Offer a mix of seed types to cater to a diverse range of bird species. It’s important to note, however, that birds which feed on stink bugs mostly prefer live insects. Thus, while bird feeders help attract birds to your backyard, their main purpose is to provide supplementary nourishment.
Step 3: Plant Fruit Trees
Fruit trees can also enhance your backyard habitat and draw in birds. Many bird species, such as bluebirds and cardinals, enjoy feasting on both insects and fruits. By offering both food sources in your yard, you can create a more attractive environment to invite these natural pest predators.
Step 4: Maintain a Clean Environment
While attracting birds to your backyard, it’s essential to maintain cleanliness and hygiene around bird feeders and habitats. Regularly clean feeders, bird baths, and surrounding areas to minimize the spread of diseases among the bird population.
Remember, not all birds can tolerate the taste and odor of stink bugs, and some may even avoid them completely. By focusing on creating a welcoming habitat for birds that enjoy snacking on household pests like stink bugs, you’ll be well on your way to a more balanced and enjoyable backyard ecosystem.
Diet and Nutrient Intake
Stink bugs are a nuisance for many homeowners, but they can also be a valuable food source for various bird species. The diet of some birds includes insects such as caterpillars, beetles, grasshoppers, and stink bugs. Birds that are known to consume stink bugs include bluebirds, swallows, martins, wrens, and even some species of ducks. These birds typically have a diverse diet that consists of various insects as well as fruits and other plant-based materials.
Insects like stink bugs provide essential nutrients such as protein and calcium that are required for the birds’ growth and overall health. Besides stink bugs, these insect-eating birds may also feast on aphids, crickets, and earwigs, which further contribute to their nutrient intake.
There are many plant-derived food sources for these birds that offer essential nutrients. For instance, bluebirds consume various fruits and berries, such as holly and sumac berries. These fruits and berries supply an ample amount of carbohydrates and other nutrients, ensuring that the birds maintain the energy required for their daily activities. Furthermore, some bird species are attracted to human-made sources of food like corn, which can provide them with a significant amount of nutrients.
The consumption of insects like stink bugs, caterpillars, and worms not only contributes to the diet of insectivorous bird species but also helps maintain the balance in ecosystems. These birds act as natural pest controllers, reducing the number of insects that may harm plants or agricultural crops. In fact, some birds are even known to eat overwintering stink bugs, which can often be found in large groups, making it a convenient food source for these birds.
Impact on Crops and Ecosystem
The brown marmorated stink bug is a significant agricultural pest, causing damage to a wide variety of crops. They are known to feed on fruit, vegetable, and field crops such as apples, apricots, Asian pears, cherries, corn, grapes, lima beans, nectarines, peaches, peppers, tomatoes, and soybeans1. This invasive species disrupts the ecosystem, leading to losses for farmers and affecting the environment.
Farmers often resort to using pesticides as a means of pest control, which can have negative repercussions on the ecosystem. Pesticides may harm non-target organisms, including beneficial insects, plants, and aquatic life. Moreover, the widespread use of pesticides contributes to reduced biodiversity and an imbalanced ecosystem.
Natural predators, such as certain bird species, can help control stink bug populations and lessen the need for pesticides. Sparrows, finches, wrens, and bluebirds have been observed eating stink bugs, providing an environmentally friendly method of pest control2. These predators contribute to a more balanced ecosystem, decreasing the dependence on chemical solutions.
In addition to affecting fruit and vegetable crops, stink bugs can also target staple crops like rice and cabbage3. The damage to these important food sources can lead to reduced crop yields and economic loss. This further emphasizes the necessity for effective and sustainable pest control methods.
As stink bugs continue to invade new territories, it’s vital to identify and implement environment-friendly approaches to control their populations and minimize the impact on crops and ecosystems. By opting for sustainable practices, such as promoting natural predators and exploring alternative pest control methods, both farmers and the environment can benefit in the long run.
Other Stink Bug Predators
When it comes to stink bug predators, there is a diverse group of animals and insects that help control their population. Apart from birds, several other creatures find these pesky insects a tasty treat.
Bugs That Eat Stink Bugs
In the insect world, ladybugs and green lacewings are known to prey on stink bugs. Both of these insects are attracted to their smell and can often be found hunting their prey in gardens and yards. Additionally, predatory stink bugs will dine on their plant-feeding cousins, providing a form of natural population control.
Spiders also play a significant role in controlling stink bug populations. They are efficient hunters and will consume many pest insects, including stink bugs. In some cases, they may even catch them on their webs or attack them directly with their venomous bites.
Assassin bugs and parasitic flies are also known enemies of stink bugs. These insects are efficient predators, stalking their prey and injecting them with venom or laying eggs inside their bodies. For example, the samurai wasp, or Trissolcus japonicus, is known to inject its eggs into stink bug eggs, effectively eliminating the next generation of pests.
Reptiles and Mammals
When it comes to reptiles and mammals, lizards may occasionally snatch up a stink bug for a snack, and even chickens aren’t shy about digging into these insects when they come across them. Rodents like squirrels and other small mammals may also eat stink bugs. However, they typically cause less impact on stink bug populations than the previously mentioned predators.
Lastly, another group of stink bug predators often overlooked are bats. These nocturnal creatures will feed on various insects, and stink bugs can make up a small portion of their diet. By controlling insect populations, bats contribute to the balance in the ecosystem.
Overall, stink bugs have plenty of predators that help keep their numbers in check. Encouraging these natural predators to live in your yard or garden can be a great form of organic pest control and ensure your plants remain healthy and stink bug-free.
Alternative Stink Bug Control Methods
Prepare Your Home
One way to keep stink bugs away is by preventing them from overwintering in your home. Seal off any openings or cracks in walls, doors, and windows to keep the insects out. Maintaining a clean, clutter-free space, especially in basements and attics, can also minimize the places they can hide.
When stink bugs are already inside, a mixture of soapy water can help eliminate them. Fill a spray bottle with water and a few drops of dish soap, then spray it directly onto the stink bugs. This will cause them to suffocate and die. Ensure that you’re careful when spraying the solution around plants, especially sensitive ones like tomatoes.
Bug zappers are another helpful tool in dealing with these pests. By attracting and electrocuting stink bugs, they can effectively reduce their population in your outdoor areas and garden. These devices are a popular choice for pest control and can be found in various styles to suit your needs.
Essential oils can also be used as effective, natural repellents for stink bugs. Some oils, like lavender, peppermint, and eucalyptus, have demonstrated effectiveness in deterring these insects. You can create a spray by mixing a few drops of your chosen oil with water and spraying it around doors, windows, and in areas where stink bugs are likely to congregate.
Remember that stink bugs can cause damage to certain plants, particularly tomatoes. To help protect your garden, consider using physical barriers like floating row covers, which can keep stink bugs from reaching your plants. Checking the leaves of your plants regularly and removing any eggs you find is another crucial step in preventing an infestation.
