Seasons change, and pest movement changes with them. Late summer in particular brings a noticeable shift in the type of pests homeowners may see. The transition into early fall means warm days but cooler nights, driving pests like stinkbugs and boxelder bugs to seek shelter closer to buildings. Mosquito Squad Plus of Northwest Indiana provides Crown Point, IN pest control for homeowners who want help managing these seasonal invaders before they settle around the house.
Why Boxelder Bugs Become More Noticeable in Late Summer
Boxelder bugs are black insects with red or orange markings that spend much of the warmer season outdoors. Their population peaks in late summer, and they spend much of the transition time looking for food and warm places to shelter. During the summer, they are typically found on trees with a preference for Box Elder, maples, and fruit trees. Some Boxelder bugs like to eat fruit and may seek resting spaces on fruit trees. You may see more Boxelder bugs in late summer as they are gathering on surfaces that retain heat as temperatures drop.
Why Stink Bugs Start Moving Toward Homes
Stink bugs are found across much of the Midwest and feed on many plants, fruits, and vegetables. Like Boxelder bugs, stinkbugs feed on vegetation and seek warm surfaces to rest on. As temperatures transition into cooler fall evenings, stinkbugs are going to gather around windows, doors, and other openings in an attempt to move indoors.
How Crown Point Weather Can Increase Pest Pressure
In addition to temperature changes, late summer brings high humidity and stormy weather into the region. The fluctuation of moisture and temperature can impact food sources for Boxelder and stink bugs. During dry stretches, most pests will seek out yards that are well irrigated or have a plethora of shade, as it helps retain moisture.
Where Boxelder Bugs and Stink Bugs Try to Settle
When several pests are active at once, Mosquito Squad Plus pest packages may provide an option based on the property and local pest pressure. Both pests can use surprisingly small openings around a home. Gaps near window frames, door trim, siding, utility penetrations, soffits, attic vents, and damaged screens may provide access to sheltered spaces. Boxelder bugs often cluster together on warm surfaces, while stink bugs commonly gather where warmth or light is available. Once they reach wall voids or other sheltered areas, they may remain hidden for long periods.
Steps Homeowners Can Take Before Fall
A few practical changes can make a Crown Point home less appealing as seasonal pest activity increases. Check screens, weatherstripping, vents, and exterior gaps, and seal openings where practical. Keep vegetation trimmed away from siding, clear leaf piles and clutter near the foundation, and harvest ripe garden produce promptly. Reducing bright exterior lighting near doors and windows may also discourage insects from gathering close to entry points.
