The brown marmorated stink bug (BMSB) has become a significant concern for both homeowners and farmers across North Carolina. Since its first detection in Forsyth County in 2009, these invasive pests have rapidly spread throughout the state, causing agricultural damage and becoming a persistent household nuisance.
Understanding Brown Marmorated Stink Bugs
Physical Characteristics
These shield-shaped insects are easily identifiable by their mottled brown coloring and distinctive white bands on their antennae. Measuring between 1/2 and 3/4 inch in length, their shield-like shape makes them readily recognizable among other household pests.
Life Cycle and Behavior
Brown marmorated stink bugs follow a predictable annual cycle in North Carolina. The adults emerge from their overwintering sites in spring and proceed to breed and feed throughout the summer months. Most insects overwinter as eggs or pupae in the ground or other protected areas outdoors. BMSBs, unfortunately, overwinter as adults and, as cooler weather arrives in the fall, these bugs often find their way into the void spaces of homes.
Natural Home and Predators
Brown marmorated stink bugs are not native to North Carolina. They are native to Asia and were accidentally introduced to the United States in the 1990s, having since spread to 47 of the 50 states.
As an immigrant species of insect, the brown marmorated stink bug has no natural predators in North Carolina. However, research is currently being conducted by North Carolina State University to test whether another immigrant insect species from Asia, Trissolcus japonicus, can reduce the number of brown marmorated stink bug eggs in peach and apple trees in North Carolina.
Impact on Agriculture and Homes
Agricultural Damage
Brown marmorated stink bugs pose significant threats to various crops throughout the growing season. Their feeding habits can devastate fruit crops such as apples, peaches, and pears, while also damaging vegetable crops, including tomatoes and peppers. Field crops, such as corn and soybeans, are similarly vulnerable, as are many ornamental plants.
Common Agricultural Impacts:
- Visible damage to fruits and vegetables through puncture marks
- Discoloration and deformation of crops
- Reduced crop yield and market value
- Secondary pest and disease issues at feeding sites
Household Nuisance
As temperatures drop in the fall, these pests seek shelter in homes, creating various issues for homeowners. When disturbed, they release an unpleasant odor that can permeate living spaces. Large indoor aggregations can become particularly problematic, potentially interfering with household equipment and causing a significant nuisance.
Prevention and Control Methods
Home Protection
Effective prevention begins with thorough inspections and regular maintenance of your property. Sealing entry points, installing proper screening, and maintaining regular inspections are crucial steps in preventing infestations. Special attention should be paid to gaps around utilities, windows, and doors where these pests commonly enter. Look for cracks around windows and doors, unscreened attic louvres, and gaps around faucets and piping. Brown marmorated stink bugs can enter your home through a gap as small as 3 mm x 7 mm.
However, it is crucial to understand that the best time of year for sealing all of those entry points is summer, as the brown marmorated stink bugs will have moved back outside at this point to feed and mate in gardens, wooded areas, and agricultural areas. If you have noticed any brown marmorated stink bugs inside your home during the fall, winter, and spring, and immediately seal all the entry points, you may inadvertently seal the insects inside with you.
Understanding seasonal patterns and implementing year-round preventive measures are key to successful management. Regular monitoring helps identify potential issues before they become severe infestations, and maintaining communication with pest control professionals ensures a quick response when needed.
Natural Control Methods
Eco-friendly approaches to control include physical removal and proper disposal methods. To avoid the unpleasant smell that occurs when disturbing these insects, one suggestion for removal is to vacuum up the brown marmorated stink bugs and then place the sealed vacuum canister in the freezer to kill the insects before disposing of them outside. This can also be done with a jar to scoop up the individual brown marmorated stink bugs, seal the jar, and place it in the freezer for several days before disposing of the dead insects. While these methods are time-consuming, they can be effective on a minimal infestation.
Chemical Control Options
When necessary, various treatment options exist, including targeted insecticide applications and barrier treatments. Professional-grade solutions, when properly applied, can provide effective control while minimizing environmental impact.
