Don’t let these pests ruin your peace of mind this Fall. Contact us today!

Don’t let mice, cluster flies, and stink bugs turn your property into their winter hideout.
As the calendar turns to September in the Hudson Valley, a subtle but significant pest shift is happening.
The warm, late-summer days are beginning to give way to crisp, cooler nights, and with this change comes a new wave of pest activity. This is the time when many of the region’s most persistent pests begin their annual search for a warm, safe place to overwinter. For both homeowners and business managers in Dutchess County and beyond, this is your wake-up call to prepare for the inevitable fall invasion of rodents, cluster flies, and stink bugs.
The September Weather Effect: A Race for Warmth
Historically, September weather in lower New York state sees average temperatures drop, especially in the evenings. The cooler weather is a natural trigger for pests to seek shelter indoors. A sudden drop in temperature in towns like Wappingers Falls or Goshen sends a clear signal to mice and rats to start looking for a cozy place to nest, and for cluster flies and stink bugs to find a crack or crevice to squeeze through.
Rodents: The Most Destructive Fall Invaders

Mice and rats are more than just an annoyance; they are a significant threat to health and property. They can chew through electrical wiring, contaminate food supplies, and spread diseases. For a business in New City or a large commercial property near I-87, a rodent problem can quickly escalate from a small issue to a major health and safety hazard that can damage a brand’s reputation.

Your Action Plan Against Rodents:
- Seal Entry Points: Rodents can fit through incredibly small openings. Seal any cracks in your foundation, around pipes, or near windows and doors.
- Remove Food Sources: Keep food in sealed containers and clean up any crumbs or spills. This includes pet food.
- Clear Clutter: Rodents love to hide in cluttered spaces, so reducing clutter in basements, attics, and storage rooms can help.
- Use Pest Control: Contact Hollenbeck Pest Control today for a free inspection and custom plan for your property.
Cluster Flies & Stink Bugs: The Great Annoyance

While not as destructive as rodents, cluster flies and stink bugs can be a major nuisance. A homeowner in Middletown might find a window covered in hundreds of flies, while a business in Kingston could have a continuous issue with them landing on lights and windows, creating a distracting and unprofessional environment. They can be particularly problematic for properties with many windows and glass entryways, as seen along Route 9W in places like Highland.
Fall brings cozy sweaters, changing leaves… and unfortunately, pests trying to sneak indoors. Let us help you keep your space warm, safe, and pest-free!

Pest of the Month

The Brown Marmorated Stink Bug
For many in the Hudson Valley, the Brown Marmorated Stink Bug is the quintessential fall pest. While they don’t bite or cause structural damage, their sheer numbers can be overwhelming as they gather on the sunny sides of homes and businesses to find a way inside. The biggest nuisance? The pungent odor they release when they feel threatened or are crushed. This is a powerful chemical defense that can linger for hours and makes them an unwanted houseguest. Professional prevention is key to keeping these unwanted tenants out before they make themselves at home.

Did You Know?

Cluster Flies vs. House Flies: Unlike the common house fly that breeds in garbage, cluster flies breed in earthworms in the soil. They are not drawn to food, but rather to the sunny side of buildings in the fall, where they gather in large clusters to find a way inside.
Stink Bugs: When threatened or crushed, stink bugs emit a foul-smelling liquid to deter predators. This is why you should never squish them. The smell can linger for hours and attract more stink bugs to the area.

April Pest & Vegetation FAQ: Frequently Asked Questions
Termites FAQ: Seasonal Activity & Risks
Termite swarming typically occurs in April when soil temperatures rise above 50 degrees Fahrenheit.
This is the period when reproductive termites leave their colonies to start new ones near properties in Orange and Rockland Counties.
Common signs include the presence of winged swarmers near windows and the appearance of mud tubes on concrete.
Property managers should also look for discarded wings on windowsills and inspect loading docks for small tunnels built by termites to stay hydrated.
Absolutely. Termites can consume several pounds of wood per year and often work from the inside out.
Because the damage is internal, it often remains invisible until the structural integrity of the beam is severely compromised.
Subterranean termites become active when soil temperatures consistently break the 50-degree Fahrenheit mark.
In the lower Hudson Valley, this biological trigger typically happens during the month of April following spring rains.
Vegetation FAQ: Perimeter Management
Vegetation management removes ‘pest bridges’ such as tall grass and overgrown brush.
By clearing these areas, you reduce harborage for rodents and prevent moisture buildup that attracts termites to the building foundation.
A sterile zone is a 3-foot perimeter of gravel or bare earth around a building.
This gap is a critical part of Integrated Pest Management, as it prevents pests from using vegetation as cover to reach the facility’s walls undetected.
Tree branches should be trimmed back at least 6 to 10 feet from the roofline.
This prevents pests like squirrels, raccoons, and carpenter ants from using branches as a bridge to enter the upper levels of the building.
April is the ‘threshold month’ where average temperatures reach 58 degrees Fahrenheit.
This specific weather combination of warmth and moisture triggers both the emergence of termites and the rapid growth of invasive weeds in New York.
Commercial Service FAQ: Plans & Compliance
Yes, professional commercial plans provide detailed digital logs and trend analysis reports.
These documents prove consistent oversight and are essential for staying compliant with local health codes and food safety audits.
Yes, warehouses near major routes like I-87 should prioritize rodent programs and stored product pest trapping.
As the weather warms in April, pests often migrate toward industrial structures looking for food sources and nesting sites.
Properties located near Route 9W, Route 32, and the Taconic State Parkway often face higher pressure.
These areas often sit adjacent to wooded corridors and agricultural sites, which serve as natural breeding grounds for various wood-boring insects.
Yes, Hollenbeck Pest Control offers after-hours service for hospitality and healthcare facilities.
This discreet approach allows us to maintain a pest-free environment without disrupting your staff, guests, or patients during business hours.
