Understanding Brown Marmorated Stink Bugs
Brown marmorated stink bugs (BMSBs) pose significant problems for homeowners. They emit a foul odor when threatened and seek indoor shelter during cooler months.
Identification
Recognize BMSBs by their distinctive features:
- Color: Mottled brown
- Shape: Shield-like
- Size: 5/8 inch (about 15-17 mm)
- Antennae: White bands
- Legs: Brown with light bands
These bugs’ unique characteristics make them easier to identify compared to other insects. If you spot these specific traits, you likely have encountered BMSBs.
Life Cycle
Understanding the life cycle helps in managing their population:
- Eggs: Laid in clusters on the underside of leaves
- Nymphs: Pass through five stages, increasing in size
- Adults: Seek shelter indoors in fall and winter
By identifying the stages of their life cycle, you can target appropriate measures to control BMSBs at various points. For instance, inspect leaves for eggs in spring or close entry points to prevent adults from entering your home in the fall.
Preventative Measures
Preventing a brown marmorated stink bug invasion starts with making your home less accessible to these pests. Carry out effective measures to reduce the chances of infestations and keep your living space stink bug-free.
Sealing Entry Points
Start by sealing potential entry points where stink bugs could infiltrate your home.
Doors and Windows:
- Ensure doors and windows fit tightly within their frames.
- Install or repair weather stripping on doors.
- Use caulk to seal gaps around windows.
Vents and Utility Openings:
- Inspect and cover vents, especially in attics and crawl spaces.
- Seal utility openings where pipes and ducts enter your home.
Cracks and Crevices:
- Examine your home’s exterior for cracks, especially around the foundation.
- Use silicone or silicone-latex caulk to seal these gaps.
Basements and Attics:
- Look for gaps and holes in your basement and attic walls.
- Seal these areas with appropriate materials to prevent entry.
Using Screen Mesh
Adding screen mesh to your home provides an additional layer of defense against brown marmorated stink bugs.
Window Screens:
- Install fine mesh screens on all windows.
- Repair or replace torn or damaged screens.
Vent Covers:
- Place screen mesh over vents to block entry points.
- Ensure the mesh is a maximum of 1/8 inch to keep bugs out.
Chimney Caps:
- Use a cap fitted with screen mesh for your chimney.
- Secure the cap tightly to prevent any gaps.
Attic Vents:
- Cover attic vents with screen mesh to block entry.
- Regularly inspect and maintain these covers.
Taking these preventative measures significantly reduces the likelihood of a brown marmorated stink bug infestation, keeping your home safe from these unwanted invaders.
Natural Remedies
Natural remedies provide an eco-friendly way to manage brown marmorated stink bugs without using harsh chemicals. These methods use readily available household items to deter and capture these pests.
Essential Oils
Essential oils can repel stink bugs effectively. Their strong scents can mask the pheromones that attract other stink bugs.
Common Essential Oils:
- Peppermint Oil: Known for its strong fragrance, peppermint oil can be an effective deterrent. Mix 10 drops with 16 ounces of water in a spray bottle and apply to entry points.
- Tea Tree Oil: This oil’s potent scent can drive stink bugs away. Combine 10 drops with 16 ounces of water, and spray in areas where stink bugs congregate.
- Clove Oil: Clove oil contains eugenol, which repels many insects. Use a similar preparation method to the ones above.
Traps
Traps can help reduce the stink bug population by capturing and eliminating them. These traps use light or pheromones to lure stink bugs.
DIY Light Traps:
- Materials Needed: Dish soap, water, a large metal pan, a light source (desk lamp or flashlight).
- Steps:
- Fill the metal pan halfway with water.
- Add a few drops of dish soap to the water.
- Position the light source above the pan to attract stink bugs.
- Leave the setup overnight. Bugs will be drawn to the light, fall into the soapy water, and drown.
Store-Bought Traps: Available at garden centers or online, these traps often use pheromones to attract stink bugs into sticky traps, effectively capturing them.
Diatomaceous Earth
Diatomaceous Earth (DE) is a natural powder made from fossilized aquatic organisms. It destroys stink bugs by damaging their exoskeletons.
- Application: Sprinkle DE around entry points, window sills, and baseboards.
- Effectiveness: As stink bugs crawl over the powder, it punctures their exoskeletons, causing dehydration.
Using these natural remedies can help you manage and reduce the presence of brown marmorated stink bugs in your home without relying on chemical treatments.
Chemical Solutions
Chemical solutions offer an effective way to combat brown marmorated stink bugs (BMSBs) when natural remedies and preventative measures aren’t sufficient. These methods involve the use of specially formulated insecticides and sprays, as well as professional pest control services.
Insecticides and Sprays
To eliminate brown marmorated stink bugs quickly, consider using insecticides and sprays approved for residential use. These products contain active ingredients designed to target and kill stink bugs.
Common Active Ingredients:
- Permethrin: A synthetic chemical effective against multiple insect species, including BMSBs.
- Cypermethrin: Another synthetic compound that disrupts the nervous system of insects, leading to paralysis and death.
- Deltamethrin: Known for its fast-acting properties and long residual effect, making it ideal for continued protection.
Application Steps:
- Identify High-Traffic Areas: Focus on places where stink bugs are most active, such as window sills, door frames, and exterior walls.
- Select the Right Product: Choose an insecticide labeled for BMSB control, ensuring it’s safe for indoor or outdoor use as specified.
- Follow Manufacturer Instructions: Carefully read and adhere to the application guidelines to maximize efficacy while ensuring safety.
- Reapply as Needed: Some insecticides require multiple treatments for complete eradication. Monitor the affected areas and reapply per the product’s recommendations.

Managing brown marmorated stink bugs requires a sustained effort for long-term effectiveness. Adopting strategies that integrate monitoring and maintenance ensures these pests stay under control.
Regular Home Inspections
Conducting regular inspections helps identify potential entry points and early signs of infestations.
- Entry Points: Examine doors, windows, and attic vents for gaps.
- Seals: Check caulking around pipes and cables that penetrate walls.
- Damaged Screens: Look for tears or holes in screens covering windows and vents.
Consistent inspections allow you to address vulnerabilities immediately and prevent stink bugs from entering your home.
