What Are Stink Bugs?

Commonly found throughout the United States, stink bugs may prove to be frustrating both to gardeners and homeowners alike. 

If you’ve ever encountered these pests, you’re probably already aware of how they get their noxious name - they really can smell awful!

Stink bugs have a natural defense mechanism that releases an odor to deter predators. They are large and oval-shaped, first introduced to the United States from East Asia in the 1990s. 

Also referred to as the yellow-brown or East Asian stink bug, these creatures are known scientifically as Halyomorpha halys. 

They grow to about ¾” long and are usually light to dark brown in color. They have lighter bands on their antennae and darker bands on the wings, with wings appearing only when the nymphs become adults. 

In the garden, you’ll usually find stink bugs hiding under stones or boards, beneath mulch, and in clumps of weeds. 

Since they suck juices from plants, you may also find them hanging out on the plants themselves. 

What Plants Are Stink Bugs Attracted To?

Stink bugs are most attracted to weeds and grasses. Most often, they feed on these green plants most often in the spring. 

What Plants Are Stink Bugs Attracted To?

As they get older, they’ll migrate to orchards and fields, eating foods like apples, pecans, beans, peppers, tomatoes, berries, peaches, and more.

That said, these bugs are opportunistic plant feeders. They use their mouths to pierce the skin of the plant and will attack just about any kind of plant for food. 

What Damage Can Stink Bugs Do In The Garden?

While stink bugs aren't the most common garden pest, they can still wreak havoc in any garden.

The females will lay their eggs on any kinds of plants that happen to be around, with both larvae and adults feeding on plant juices.

They may even eat the fruits on your plants. Some of their favorites include corn, beans, peppers, tomatoes, and more.

What Damage Can Stink Bugs Do In The Garden?

Identifying the damage from these bugs is a crucial step in getting them out of your garden.

You’ll likely notice damages such as tiny pinpricks in leaves that are ringed by green or yellow.

Just one or two stink bugs in the garden probably won’t prove to be devastating, but when numbers grow larger, that’s when the damage will start to get out of control. 

They can almost completely dehydrate a plant, and even if they don’t, their voracious feeding habits can lead to severely stunted growth and a weakening of your plants.

How To Prevent A Stink Bug Infestation In The First Place

When it comes to preventing a stink bug infestation in the garden, there are several steps you can take to reduce the likelihood that these pests will rear their ugly heads in the first place.

How To Prevent A Stink Bug Infestation In The First Place

One of the easiest is to keep the garden clean and tidy at all times. Remove any nearby weeds or overgrown bits of vegetation. 

At the end of the growing season, take the time to clean up the garden, removing any old fruits, plant parts, or rotting wood. 

In the garden, there are several plants you can grow as trap plants. Trap plants, or decoy plants, will lure stink bugs away from your most prized plants. This technique is known as companion planting, which you can learn all about in our complete guide.

Basically, the stink bugs will leave the plants you actually want to cultivate alone. Instead, they’ll flock to the trap plants and hang out there rather than munching on your favorite edible crops.

Some plants you can grow to trap stink bugs include sunflowers, amaranth, and mustard. 

Preventing Stink Bugs In A Grow Room

If stink bugs are problematic in your grow room, you need to close up any potential entryways.

It's very likely your grow isn't sealed, which creates an increased likelihood of pests. It also decreases your ability to optimize the growing environment, and truly cultivate great plants.

This is why we highly encourage all indoor growers to utilize a grow tent or or better yet, a complete grow tent kit.

The latter contains everything you need to start growing indoors, setting you up for success from the jump.

How To Get Rid Of Stink Bugs In The Garden Naturally

Sometimes you can do everything right and still end up with an infestation in your grow room or garden. Don't worry, because now we're going to teach you how to get rid of stink bugs in the garden.

Get Rid Of Stink Bugs In The Garden Naturally

One of the easiest ways to get rid of stink bugs in a more natural way is to use a natural repellent. Stink bugs will lay their eggs and feed on garden plants. 

Using a mineral clay solution can help prevent the bugs from laying their eggs and it’s safe for use even on edible plants. 

You can also use a pheromone spray to lead stink bugs away. Another natural way to get rid of stink bugs is to attract some of their natural enemies - beneficial bugs.

There are all kinds of insects and other animals that feed on stink bugs, including birds, toads, spiders, ladybug, lacewings, praying mantis, minute pirate bugs, and parasitic flies. 

Attract them to the garden (for example, by growing plants they love or putting out birdbaths or other water sources) and your stink bug problem should disappear. 

Try Diatomaceous Earth

Using diatomaceous earth is a great natural approach to controlling stink bug outbreaks in the garden.

This product is organic, and you can spray it wherever your problem areas are. It will dry, leaving behind tiny glass-like shards. When stink bugs crawl over these, it cuts them open and dehydrates them.

It needs to be reapplied often, and you may even consider spreading some of this around your grow media, not just the foliage. We have a complete guide on using diatomaceous earth if you want to learn more.

What Kills Stink Bugs In The Garden?

There are several products you can use to kill stink bugs in the garden, many of which are completely organic and safe.

Neem oil is one natural option that can be used to get rid of stink bugs. All organic growers should check out our guide on when & how to use neem oil, as it's a powerful, natural pest control solution. A similar product you may want to learn how to use is insecticidal soap.

When it comes to killing stink bugs in the garden quickly and safely, though, a pesticide is your best bet. Look for products that contain pyrethrin. Some that come to mind are:

Where Do Stink Bugs Lay Their Eggs On Plants?

To eradicate a stink bug infestation, it’s essential that you target both adult stink bugs as well as their eggs. 

Females lay large quantities of stink bug eggs, depositing them on the underside of plant leaves

Where Do Stink Bugs Lay Their Eggs On Plants?

They can lay up to 100 eggs at once, putting them in rows of 12 or more. These eggs are tiny, shaped like pistachios. 

You can use a stick to scrape stink bug eggs off the bottoms of leaves. You can also remove the leaf and drop it in insecticidal soap or a bucket of soapy water. 

This should kill the eggs immediately and help reduce stink bug populations in your garden.
