Natural Ways to Get Rid of Stink Bugs in Garden

Do you need to know how to get rid of stink bugs in garden? Here, I will provide you with some useful information to deter these tiny, smelly insects from your space.

It is no secret that plenty of stink bug types are not dangerous to plants. Nevertheless, the brown marmorated species are an exception.

This variety of stink bugs will be one that you want to keep at bay the most. They feed on the sap of your favorite plants, leaving them distorted. 

Besides, stink bugs can decrease the aesthetic of your indoor space by sticking together in a group. Not to mention, their coriander-like reek is obnoxious for many.

Reasons to Be Concerned about Stink Bugs

In addition to the matters mentioned previously, brown marmorated stink bugs also pose many other issues in the garden.

One of the major problems is these bugs are not picky about what they eat. In other words, any kind of plant you grow in the garden is prone to their threat. 

These stink bugs feed on over 100 plant species, including woody and ornamental plants, as well as fruit trees like apples.

Moreover, various flowers and leaves become the target of these bugs. You must pay attention to your seedpods too as stink bugs may eat up them.

The affected plants typically get discoloration, blemishes, or deformities and experience early decay.

Despite their small sizes, stink bugs can be the major reason for crop damage once established in a location.

You may wonder what attracts stink bugs in your house and garden as this knowledge will help you avoid them in the first place.

Similar to many other living beings, stink bugs are interested in food. 

As a result, it is not surprising to see them around your house if you are leaving your meals uncovered on the countertop. 

Instead, you can take advantage of airtight food storage containers to keep your meals. 

Your trash bin is another reason for stink bugs wandering inside your house. Hence, you should always cleanse your can thoroughly and discard the garbage regularly. 

Do not forget to wipe out any bin juice with a steam cleaner or antibacterial wipes as well. Besides, you need to clean your counters and sweep the floors to get rid of scum and crumbs from spills. 

Stink bugs life cycle

Although there are different varieties of stink bugs, they normally have the same life cycles. These insects grow through an incomplete metamorphosis that involves three phases, including eggs – nymphs – adults.

  • Eggs

The development of egg masses starts in the spring when female adults deposit their eggs after mating with males.

  • Nymphs

Nymphs of stink bugs undertake five stages of development. During this life cycle, they have no wings and increase in size through the progress of their nymphal instars. 

Each nymphal stage takes around seven days to complete. Accordingly, these bugs turn into fully-grown adults with wings and the ability to reproduce themselves. 

  • Adults

Adult stink bugs will eat up plants or fruits and reproduce in the summer. Taking the varieties and the location they reside in, these pests may generate up to 400 eggs throughout their life.

Furthermore, their life expectancy as adults varies between six to eight months.

These bugs harm plants by piercing and sucking sap from buds, fruits, flowers, and foliages. This action results in stunting plants, wilted leaves, and damaged seedlings. 

You may also notice apparent pits and spots on your plants due to the attack of stink bugs. Besides, crops may drop, change in shape, or even completely fail to form.

Stink bugs frequently look for warmth in the winter, encouraging them to make their way indoors. These pests will hide in any cranny and nook around the house.

Think about basements, cracks, attics, and under furniture when you are examining for their presence at home. 

Outdoors, you may find them hiding on sunny garden walls, underneath rocks, and on windowsills.

Different from some other pests, these insects will not cause any structural damage. However, having a group of stink bugs at home is still far from ideal.
