Essential Tips for Handling Stink Bugs, Cluster Flies, and Other Insects During Winter

Winter’s arrival often brings more than just cold weather—it can also lead to a surge in pests seeking warmth inside your home. Stink bugs, cluster flies, and other winter pests are common culprits and managing them effectively requires targeted strategies. 

Here’s how to tackle these winter pests during the season:  

Understanding the Problem

Identifying and understanding stink bug and other winter pests’ behaviors can help you effectively address infestations. 

Stink Bugs 

Stink bugs are notorious for their ability to emit a foul odor when disturbed. These bugs are typically brown, measuring about 1.5 inches long, and have a distinctive shield shape. Stink bugs search for warm places to hibernate as temperatures drop, often making their way into homes through tiny cracks and crevices.

Cluster Flies 

Cluster flies, distinguishable by their larger size (approximately 1/4 inch long) and sluggish flight, tend to invade homes in large numbers. Unlike other flies, cluster flies do not breed indoors but seek shelter in attics, walls, and other secluded areas. They are attracted to warmth rather than food

Prevention Strategies 

Implementing preventive measures can help keep stink bugs and other winter pests from entering your home in the first place. 

Seal Entry Points   

To prevent stink bugs and cluster flies from entering your home, thoroughly inspect and seal any gaps or cracks. Use high-quality caulk or expandable foam for larger openings around windows, doors, and the foundation. Pay special attention to areas around vents, utility pipes, and basement windows where pests commonly enter. Installing door sweeps and repairing damaged weather stripping on doors and windows will also help keep pests out. 

Inspect & Repair Screens  

Ensure that all window and door screens are intact and free of holes. Replace any damaged screens with new ones with a fine mesh to keep out even the smallest insects. Regularly check for and repair any gaps around screen frames to ensure a tight fit. 

Maintain Cleanliness

Regularly vacuum carpets, floors, and upholstery, especially in areas where stink bugs and cluster flies might hide. Use a vacuum with a HEPA filter to capture any eggs or larvae. Keep storage areas, attics, and basements clutter-free to reduce potential hiding spots.

Manage Existing Infestations 

When stink bugs and other winter pests have already invaded, these strategies can help control and reduce their numbers. 

Vacuuming

Use a vacuum with a HEPA filter to capture insects and prevent their eggs from spreading. Immediately dispose of the vacuum bag or canister contents outside to avoid re-infestation. 

Use Pesticides Carefully 

If vacuuming doesn’t fully address the problem, consider using targeted insecticides. For stink bugs, look for products labeled as effective against these pests, often containing pyrethrins or other active ingredients. For cluster flies, use fly sprays or aerosols in areas where they congregate. Always follow label directions and apply pesticides in well-ventilated areas, avoiding excessive use. 

Trap Placement

Use fly traps specifically designed for these pests to manage cluster fly populations. Place traps near windows, light fixtures, and other warm areas where cluster flies are commonly seen. These traps use attractants to lure and capture flies, reducing their numbers over time.
