Stink Bug Vs Squash Bug

Stink bugs and squash bugs are two common pests that can do a lot of damage. Since they’re both small and like squash plants, which they have in common, some differences make them different.

Stink bugs are part of a big group of insects that stink when they are scared or crushed. There are many species, yet the brown marmorated stink bug is a common one that has become a nuisance in many places around the world. But squash bugs stand out because their oval-shaped bodies have orange stripes.

Both stink bugs and squash bugs feed on various types of squash, including zucchini, pumpkin, and butternut squash.

Their life stages and feed habits, however, vary. Stink bugs have sharp mouthparts that they use to get plant juices. This hurts the fruits and leaves. Squash bugs lay eggs on the undersides of leaves. Adults and nymphs of squash bugs feed on plants, which causes them to wilt and grow slowly.

In our guide, you can learn more about the world of stink and squash bugs and how to tell them apart. By the end, you’ll know the differences between squash bugs and stink bugs and how to take preventative steps to ensure your garden is resistant to squash bugs and stink bugs.

Are Squash Bugs and Stink Bugs the Same Bug

Are squash bugs and stink bugs the same bug? While both squash and stink bugs are insects and belong to the same order, they aren’t the same bugs.

Squash bugs (Anasa tristis) and stink bugs (Pentatomidae) are different species with distinct characteristics.

Squash bugs are narrow and brown or gray, with black legs, and these leaf-footed bugs can also transmit bacterial wilt, a disease that affects plants in the squash family.

However, stink bugs come in various colors and shapes, with wider and rounder bodies. They can also be found in gardens and may cause damage to crops.

Differences Between A Stink Bug and Squash Bug

There are several key differences when comparing stink and squash bugs.

Stink bugs come with wider bodies

Stink bugs, specifically the brown marmorated stink bug, are a common pest that causes significant damage to crops in the cucurbit family, including cucumbers, melons, and squash. These bugs overwinter in sheltered areas and emerge in the spring to feed on the developing fruits and leaves of the plants.

Stink bugs are often brown or green and have distinctive, shield-shaped body. They release a foul odor when crushed, or you squish them, hence their name. (Read Neem Oil Spray For Bed Bugs)

Squash bugs are rounder in shape

While stink bugs are wider and have a more shield-shaped body, squash bugs look rounder than squash. This difference in shape can help you quickly tell them apart.

Squash bugs may prefer to feed on the undersides of leaves, while stink bugs feed on various plants. Another distinguishing feature is squash bug eggs.

Squash bugs lay small, copper-colored eggs in clusters on the undersides of leaves or in piles of dead leaves.

Squash bugs are shorter

While both bugs belong to the same order, Hemiptera, and share some similarities in appearance, like their flat bodies and piercing-sucking mouthparts, their sizes differ.

Squash bugs typically measure around 0.5 inches, whereas stink bugs are slightly longer, averaging around 0.6 inches. Squash bugs are wider and rounder compared to stink bugs. Understanding these distinctions can help distinguish between the two species.

Squash bugs overwinter in plant debris, while stink bugs seek shelter in various overwintering sites. Both bugs lay their eggs on the undersides of plant leaves and can have multiple generations in a year.

Squash bugs also have bell-bottomed areas on their hind legs.

Squash Bugs vs. Stink Bugs–Eating Habits

Squash bugs and stink bugs have distinct eating habits. Squash bugs feed solely on squash plants, while stink bugs don’t eat cucurbits like squash.

Squash bugs only eat squash

If you’ve ever wondered what squash bugs eat, you’ll be interested to know that they only eat squash. The adult squash bug, about half an inch long, belongs to the cucurbit family and is a common pest in gardens.

These invasive species prefer feeding on plants like pumpkins, zucchinis, and other cucurbit family members. Squash bugs can cause significant damage to your squash plants, sucking the sap and causing wilting and discoloration.

Now, let’s move on to the next section and discuss how stink bugs differ from squash bugs’ eating habits.

Stink bugs don’t eat cucurbits

You’ll be relieved that stink bugs don’t eat cucurbit plants like squash bugs. While squash bugs feast on squash plants and the various squash, stink bugs prefer other plants.

Stink bugs, or shield bugs, primarily feed on various plants, including fruits, vegetables, and ornamental plants. However, they don’t have a specific attraction to cucurbits like squash bugs do.

Squash bugs can cause significant damage to squash plants, injecting a toxin and then sucking the sap from the leaves and vine, thus causing the plant’s wilting and death. 

These insects can be quickly recognized by their distinct shield-shaped bodies, which are wider and rounder than squash bugs but narrower than stink bugs. They typically measure about half an inch.

A Stink Bug’s Life Cycle

During their life cycle, stink bugs go through several stages of development. These bugs find their way into gardens and crops, including different species of squash plants.

Stink bugs are known for their foul odor, emitting when threatened or disturbed. This foul smell acts as a defense mechanism against predators. Shield bugs, as they’re sometimes called, lay their eggs on the undersides of leaves, usually in clusters.

The eggs hatch into nymphs resembling smaller versions of adult stink bugs. As the nymphs grow, they molt several times, shedding their exoskeletons. Eventually, they reach adulthood and continue their life cycle.

It’s important to note that while stink bugs may be a nuisance in gardens, they don’t cause any harm to humans. However, their presence can make certain crops, like spaghetti squash, taste bad.

How to Get Rid Of Squash Bugs and Stink Bugs in the Garden

To effectively eliminate squash bugs and stink bugs in your garden, start by implementing proactive pest control methods.

Squash bugs are commonly found in gardens and can be identified by their flat, oval-shaped bodies and brown or gray coloration. Stink bugs are rounder than squash bugs and have a shield-shaped body.

To control stink bugs or squash bugs, manually remove them by handpicking or knocking them into a bucket of soapy water. Regularly inspecting the plants for bug eggs and destroying them before they hatch can help prevent infestation.

Remember to pay special attention to winter squash, as squash bugs are particularly attracted to this type of plant. If you notice a yeast spot on your winter squash, it may show the presence of squash bugs, so act quickly to prevent further damage. (Read Potato Bug Bite)

Homemade Insecticide for Squash Bugs and Stink Bugs

Make your homemade insecticide to control squash and stink bugs in your garden effectively.

Squash bugs and stink bugs belong to the Hemiptera order and are known for their ability to damage plants by sucking out their juices. They can also transmit diseases to your garden plants.

To make a homemade insecticide:

1. Mix one tablespoon of dish soap with one quart of water.
2. Fill a spray bottle with the mixture
3. Spray it directly on the bugs, focusing on their eggs and nymphs. The soap will suffocate and kill the bugs.

Remember to spray the underside of leaves, as this is where the bugs often hide.

This homemade insecticide is safe to use and can help control squash bugs, stink bugs, and the Western conifer seed bug.

Conclusion

In conclusion, while squash bugs and stink bugs may share some similarities, they’re indeed different bugs with distinct characteristics. From their eating habits to their life cycles, these pests can cause significant damage to gardens.

However, we can effectively eliminate them with the right knowledge and homemade insecticide. Just as skilled gardeners tend to their plants, we must protect our gardens from these unwanted visitors.
