As temperatures dip and leaves begin to carpet lawns, homeowners across the Treasure Valley notice an influx of fall pests seeking warmth and shelter indoors.

For reliable protection backed by local expertise, trust fall pests to ProGuard Pest Control, your locally owned & operated, veteran-owned partner with no contracts, a 100% satisfaction guarantee, and family & pet safe treatments.
Understanding Common Fall Invaders
Boxelder Bugs: A Seasonal Challenge
Boxelder bugs are slender, black insects marked by bright red or orange wing veins. In early autumn, they congregate on south-facing walls, basking in the final warm rays of sun. As nights cool, they search for crevices to overwinter, often entering homes through gaps around windows, doors, and utility lines.
Pro Tip: Inspect window frames and door thresholds for small openings; a strip of high-quality silicone caulk can deter boxelder bug entry by sealing even the tiniest gaps.
Appearance and Behavior
Adult boxelder bugs measure about ½ inch long and have a distinctive flat, segmented body. They feed primarily on the seeds of boxelder trees but will also nibble on maple and ash, leaving faint, yellowish spots on leaves and fruit.
Pro Tip: Remove fallen boxelder seeds and debris from around the foundation of your home to reduce nearby food sources and discourage large populations.
Why They Invade
These insects are heliophilic—attracted to sunlight—and seek the warmth of building exteriors as days shorten. Once indoors, they gather in groups in attics, wall voids, and crawlspaces, emerging on sunny days to feed and mate.
Pro Tip: Install fine-mesh screens on attic vents and soffits to maintain ventilation while blocking bug entry.
Other Notorious Autumn Invaders
While boxelder bugs are the headline act, homeowners often encounter several other fall pests. Understanding their habits is key to preventing an invasion:
- Stink Bugs: Shield-shaped and brownish, these bugs emit an unpleasant odor when disturbed.
- Lady Beetles: Also known as Asian lady beetles, they seek shelter in wall voids and can stain walls with their yellow-orange secretions.
- Cluster Flies: Slightly larger than houseflies, they move sluggishly and often form clusters on ceilings.
Pro Tip: Use household vacuum cleaners with fine filters to remove clusters before they scatter; dispose of the bag promptly to prevent re-infestation.
Health and Home Risks of Autumn Invaders
Structural Concerns
Pest entry points can allow moisture and drafts, leading to mold growth and increased energy bills. In severe infestations, insect bodies and frass can accumulate in vents and walls, compromising insulation efficacy.
Pro Tip: Schedule a professional inspection in early fall to identify vulnerable areas and reinforce seals around utilities and foundation joints.
Allergens and Air Quality
Some fall pests, especially cluster flies and lady beetles, can trigger allergic reactions in sensitive individuals when their bodies decompose in hidden areas. Particulate matter from insect debris may circulate through HVAC systems, reducing indoor air quality.
Pro Tip: Replace HVAC filters monthly during peak pest season and consider HEPA-grade filters to capture fine allergenic particles.
Effective Prevention Strategies
Seal Entry Points
Thoroughly inspect your home’s exterior for cracks wider than 1/16 inch. Common spots include around window frames, door jambs, utility penetrations, and foundation seams. Silicone-based caulks and copper mesh are excellent materials for long-lasting protection.
Pro Tip: Conduct a “flashlight test” at night: shine a bright light inside your home and look for outdoor light leaking through gaps.
Landscape Management
Trim shrubs, tree limbs, and ivy away from walls to remove bridges pests use to access roofs and attics. Clearing leaf litter and fallen fruit reduces breeding grounds and discourages lingering populations near your home.
Pro Tip: Maintain a 12- to 18-inch buffer of gravel or decorative rock around the foundation to deter climbing insects.
Professional Inspection and Barrier Treatments
While DIY measures can reduce entry, ongoing prevention benefits from expert application of barrier treatments. A perimeter spray around the foundation and eaves creates a protective zone that repels and eliminates fall pests before they invade.
Pro Tip: Schedule quarterly service visits to maintain continuous protection—especially during seasonal transitions.
