The presence of bugs in your garden creates an impression that they harm your landscape, and you should find ways to repel them. However, it's essential to assess whether such bugs can benefit your landscape. Stink bug insects can offer some unique advantages to your landscape.
| Role of Backyard Bugs | Details |
|---|---|
| Pest Control | Certain species of stink bugs, like the predatory spined soldier bug, feed on other insect pests such as caterpillars, beetle larvae, and other soft-bodied insects. This natural predation can help control populations of harmful garden pests. |
| Biodiversity | A diverse range of insects, including these bugs, can contribute to a balanced garden ecosystem. This biodiversity helps maintain ecological stability and prevents species from becoming overly dominant. |
| Pollination | Although not their primary role, some bugs may inadvertently assist in pollination as they move from plant to plant, feeding on nectar or other plant parts. |

The presence of aggressive and invasive insects in your backyard garden is not the most pleasing aspect. They can quickly damage your crops and lower your expected yields. Therefore, as a proactive gardener, you should ensure you have unique strategies to repel stink bugs before they dominate your landscape. But first, it's essential to understand the damage that these backyard bugs can cause to your garden.
| Stink Bug Damages | Details |
|---|---|
| Crop Yield Loss | Direct damage to the plants can significantly reduce yield. The bugs' feeding can stunt plant growth, reduce fruit set, and cause fruits to drop prematurely. |
| Quality Reduction | The aesthetic and structural damage to fruits and vegetables can make them unmarketable, leading to economic losses for farmers. |
| Economic Impact | Farmers may incur additional costs for pest control measures, including insecticides and monitoring systems, to manage stink bug populations. |
| Deformation | Fruits and vegetables may become deformed and discolored. |
| Necrotic Spots | Brown or black spots can appear on the surface of the fruit where the bugs have fed. |
| Cat-facing | Feeding damage can cause fruits like peaches to develop sunken, pitted areas, known as cat-facing. |
| Transmission of Plant Pathogens | Some stink bugs are known to be vectors of plant pathogens, further complicating their management and increasing the risk of disease spread among crops. |
How to Repel Stink Bugs
Use cultural, biological, and physical pest control methods

Although stink bug insects can help control pests, enhance backyard biodiversity, and assist with pollination, their damage outweighs their benefits. Therefore, you should incorporate proactive techniques to help remove these insects from your landscape.
- Cultural Control: Use gardening practices such as crop rotation, timely planting, weeding, handpicking, and diverse cropping to help disturb the pest development cycle.
- Biological Control: According to the University of Missouri Extension, you should encourage natural predators like birds, and spiders and beneficial insects such as ladybugs and parasitic wasps. Some parasitic wasps specifically target stink bug eggs.
- Physical Control: Using floating row covers protects young plants from stink bugs. You can also use screens or barriers around the garden to prevent garden pests from finding a foothold in your landscape.
- Preventive Measures: Seal cracks and gaps around windows, doors, and other entry points to prevent stink bug insects from entering your home. Keep your garden clean and free of plant debris where bugs can hide.
Avoid using chemical pesticides as a pest control method. Chemical pesticides can harm beneficial backyard insects and can cause environmental pollution.
