When the Landscape
Comes Right Up to the House

Cornwall has long been associated with the scenery of the Hudson Highlands.

 

Storm King Mountain, the Hudson River and Moodna Creek are woven into the town’s history, and Cornwall’s landscape helped make the area a destination for artists, writers and summer visitors.

 

On many properties, that natural environment isn’t somewhere in the distance.

 

It’s in the backyard.

 

Trees may stand close to the roof.

 

Sloped ground meets foundations.

 

Vegetation surrounds outdoor living areas.

 

Wildlife moves through wooded surroundings.

 

Those conditions call for pest control that understands the relationship between the landscape and the structure.

SOMETIMES YOU
HAVE TO LOOK UP

The Roofline Can Be Just as Important as the Foundation

A lot of pest inspections naturally begin near ground level.

 

In Cornwall, looking higher can be just as important.

 

Mature trees and wooded surroundings can bring insects and wildlife closer to roofs, gutters, soffits and upper portions of a home.

 

Squirrels don’t need to use the basement.

 

Bats don’t need a ground-level opening.

 

Stinging insects may establish activity around roof edges.

 

Spiders can benefit from insects gathering around exterior lighting and upper entryways.

 

That’s why Hollenbeck considers the complete structure.

  • elizabeth cuesta
    Matt came out for same-day yellow jacket removal. He quickly removed the nest from the foundation while working in the basement. He was very friendly,… knowledgeable, and professional. We are so happy with all the services Hollenbeck offers- the very best! Thank you!!
  • Robert Wickham
    Rob was amazing. He knew exactly what to do and wasn’t afraid to get dirty and get the job done. An absolute professional, and sweet to my young son who was… there too. I am so happy we called when we did!
  • Laura Ingrassia
    Rob from Hollenbeck stopped to help me on his way home from work when he saw me stranded at the side of the road with a flat tire. He was so professional and… cheerful about changing a tire! I would gladly consider Hollenbeck in the future for pest control needs.
  • T Brunson
    I had a great home inspection from Hollenbeck Pest Control. The technician's name was Danielle. She was well informed and extremely patient. She took the time… to explain what the risks were with certain pest's presence and what services Hollenbeck offered to help. She was so well versed in pest control in general and exactly what Hollenbeck 's policies and procedures are in a myriad of scenarios, that I signed up for the annual protection package.
  • Brandi Colon
    We've been with Hollenbeck many years now and have never had a bad experience. Our technician, Max, was extremely polite and addressed all of our concerns! Max… throughly explained everything he planned to do, everywhere he sprayed and even told us specific places he thought we should keep an eye on. He has been to our location before and is always a pleasure to work with!
  • Ada Freeman
    Rob was on time and very thorough. He explained the corrective process and the 3 levels of service. Rob was knowledgeable and I hope to work with him again.
  • Melanie Mattera
    We are quite pleased with the service call by Rob D. From Hollenbeck Pest Control today. Rob was early for our appointment, pleasant and very knowledgeable. … This was our first experience with a pesky mouse and he explained the steps to take to prevent any further unwelcome critter visits. Rob came to assess the situation but was then able to service our issue. At this time we feel more comfortable in our home and welcome the follow-ups. Hollenbeck was recommended to us and now we highly recommend them.
  • Deborah Gilson
    I want to sing the praises of Nora the person who helped me with our pest challenge. She was kind, empathetic and reassured me and gave an action plan to… try. The owners of Hollenbeck are so fortunate to have her as the initial contact for future customers! Thank you for your kindness Nora!
  • Matthew Tether
    Excellent, timely, attentive service with good follow up to make sure we were satisfied. Also best pricing. The best!!
  • Marcy S
    I've used Hollenbeck in the past for more emergent problems. This time I called them in for preventative measures. As in the past they showed up, explained my… options, offered reasonable solutions, and treated the problem. Fernando was extremely knowledgeable, personable and careful. He took my concerns into consideration when formulating a plan. A++
  • Office staff are lovely and got us scheduled right away! Danielle was our technician and she gave us some great information and advice moving forward.
  • I ended up at Hollenbeck Pest Control the other day and had a really great experience. The office staff was incredibly friendly, welcoming, and took the time to… answer all of my questions without rushing me. You can tell right away that they genuinely care about the people they’re helping. As someone who also owns a pest control business, I pay close attention to how companies operate—and this one stands out. The way they treat customers and how professionally everything is handled speaks volumes about how the company is run. It’s not often you come across a team like this. Truly good people, and I would strongly recommend Hollenbeck Pest Control based on this experience alone.
  • Karen Grodnick
    Great experience with pest inspection and services. Rob is professional, friendly and takes the time to explain everything to me. Office staff (Tiffany) is also… very friendly and helpful. I def recommend!
  • Jennifer Campos
    Robert D. Came out to my home today to assess my house and offer services. Since I live in a log cabin, it was important that we attack the wood eating and… burrowing insects. I was also worried about my dogs and all the birds I seem to attract. He was so thorough in his explanation about the services and what insects I really need to look out for, so I wound up signing up for a program right there on the spot. Robert was great to talk to and work with. Thank you for the great service Robert and I'll see you again soon!
  • Anita Contreras
    Thank you for a wonderful job. I had a hornets nest in a tree hanging into street. I called Hollenbeck because of their great reviews and now I am completely… satisfied too. I was scheduled quickly and easily, my technician was respectful and very thorough in his job. He told me he does his work from his heart. I an very happy with Hollenbeck and if I ever have any other pest issues I will call then first.
  • Maria Ramirez
    Robert did a great job! He was polite, professional, and thorough. He explained everything clearly and provided excellent service. Highly recommend!
  • Christine Susskind
    Fantastic service. They came within 2 hours of my calling and took care of a large wasp nest quickly and safely. Highly recommend.
  • Jeremy Zareski
    I returned home from vacation to find yellow jackets flying around my basement. It was Saturday, but I called Hollenbeck, who I’ve had a service plan with for… the last few years, hoping to schedule an appointment when they opened the following week. Much to my surprise, they said they could dispatch someone same day for a nominal fee. The tech, Robert D., did a great job with a challenging situation involving a huge yellow jacket nest that infiltrated the foundation of my home, taking the time to explain every step he was taking to resolve the problem. I’ve been very satisfied with Hollenbeck in the past, and this experience further reinforces that I’m dealing with the most professional pest control company in the area. I appreciate both the quick response time (same day on a Saturday!) and the quality of the customer service provided in the field. Would strongly recommend. A+++
  • Ian Kennedy
    Max and Danielle are awesome! This company exemplifies kindness and professionalism. The technicians and office are great. I have had nothing but great experiences
  • Deijana Lebron

Hills, Trees ,and Water Change How a Property Functions

Cornwall isn’t flat.

 

That’s an obvious statement, but it can have real implications around a home.

 

The Hudson Highlands define much of the area’s landscape, while Moodna Creek and smaller waterways cut through the surrounding terrain. Storm King Mountain has been central to Cornwall’s identity for generations.

 

A sloped, wooded property behaves differently from a level suburban lot.

 

Water Moves Downhill—and Sometimes Toward the House

 

Grade and drainage deserve attention.

 

Rainwater moving across a slope can collect near foundation areas if drainage isn’t working properly.

 

Gutters and downspouts become important.

 

So do damp portions of the landscape.

 

Persistent moisture can affect several insects and contribute to the deterioration of wood or other materials.

 

Carpenter ants, for example, can establish nesting galleries in damp or damaged wood.

 

Silverfish favor humid environments.

 

Mosquitoes can take advantage of standing water when it persists.

 

The solution is not automatically pesticide.

 

Sometimes the property is telling you something that needs to be corrected.

 

Trees Connect the Yard to the Roof

 

Branches close to a structure can create pathways toward upper portions of a building.

 

Squirrels are obvious climbers.

 

Other wildlife and insects can benefit from vegetation contacting roofs, siding or other exterior surfaces too.

 

Homeowners don’t need to remove every tree near their house.

 

Strategic pruning and maintenance can simply make the transition between the landscape and building easier to manage.

 

Wildlife May Already Be Traveling Through the Yard

 

Cornwall’s wooded surroundings provide natural habitat.

 

A raccoon crossing the backyard isn’t automatically a pest problem.

 

Neither is a squirrel living in a tree.

 

The situation changes when an animal begins using a chimney, attic, shed, crawl area or space beneath a deck.

 

At that point, understanding where it’s entering becomes critical.

 

Tick Management Is About Where People and Wildlife Overlap

 

Ticks aren’t distributed evenly across every lawn.

 

Wooded edges, leaf litter, shade, vegetation and routes used by wildlife can be more relevant than open sunny grass.

 

That makes property layout important when developing a tick-control program.

 

Where does the dog run?

 

Where do children play?

 

Where does maintained lawn meet the woods?

 

Those practical questions help focus attention on the areas that matter.

 

Winter Creates a New Reason to Approach the House

 

When outdoor conditions become less hospitable, structures offer shelter.

 

Rodents may investigate gaps.

 

Overwintering insects may gather on warm exterior surfaces.

 

Wildlife may explore attics and protected areas.

 

A Cornwall home’s relationship with the surrounding landscape doesn’t end when summer does.

 

It simply changes.

Cornwall Pest Control FAQs

What pests are common in New Windsor?

New Windsor properties can experience a wide variety of pest problems throughout the year, including ants, mice, rats, ticks, mosquitoes, stink bugs, spiders, cockroaches, centipedes, flies, fleas, stinging insects, termites, and overwintering pests. Nuisance wildlife such as squirrels, raccoons, bats, groundhogs, and skunks can also cause problems around local properties.

Stink bugs are overwintering pests. As temperatures drop in the Hudson Valley, they look for protected places to survive the colder months and can enter homes through small gaps around siding, windows, doors, utility penetrations, and other openings. Hollenbeck offers exterior overwintering treatments designed to help reduce activity before these pests move indoors.
Ticks are an important concern throughout the Hudson Valley, particularly around properties with wooded edges, leaf litter, groundcover, tall vegetation, and other suitable habitat. Hollenbeck offers targeted tick treatments focused on areas where ticks are most likely to live and breed.
Rodent activity can become particularly noticeable as temperatures fall because mice and other rodents seek warmth, food, and protected nesting locations. Small openings around a home can provide enough space for rodents to gain access to wall voids, basements, garages, attics, and other areas.
Yes. Hollenbeck provides wildlife control for nuisance animals including squirrels, raccoons, bats, groundhogs, skunks, birds, and opossums. Our team evaluates the situation and develops a solution based on the animal and property.
Not every property requires the same service frequency. Hollenbeck offers both single treatments and preventative service plans, with options ranging from weekly service to once-a-year treatments depending on the property’s needs. Our plans can cover more than 30 common pests.

Yes. Hollenbeck offers warranties ranging from 30 days to one year depending on the pest and service performed. Our philosophy is simple: “If the pests return, so will we.”

Yes. Hollenbeck Pest Control is headquartered at 273 Quassaick Avenue in New Windsor, NY. We’re a local, family-owned company that has been operating since 2008, backed by more than four generations of experience serving the Hudson Valley.

They can provide routes toward roofs and upper portions of a structure. That doesn't mean trees must be removed, but branches contacting or overhanging a building may deserve attention.
Changes in moisture can influence pest activity, and water movement around foundations may affect basement humidity. Repeated activity is worth evaluating along with drainage and moisture conditions.
Not every wooded property has the same level of activity, but wooded edges, leaf litter, vegetation and wildlife can create suitable tick habitat.
Usually not. Wildlife becomes a pest-management issue when it begins damaging property, entering structures or creating another specific problem.
Yes. Bats can use relatively small structural gaps, making roofline and upper-building inspection important when attic activity is suspected.
Sun-exposed exterior walls can become warmer during autumn afternoons, making them attractive gathering locations for stink bugs before they seek winter shelter.
Yes. Hollenbeck provides commercial pest management in addition to residential service.
