What is DeerTech® and how does it work?

DeerTech® is SavATree's patented three-pronged deer deterrent solution that combines ultrasonic sound devices, repellent treatments, and continuously changing tactics to keep deer from adapting to any single method.

Is DeerTech® safe for pets, people, and other wildlife?

Yes, DeerTech® is completely safe for deer, pets, people, and plants while effectively discouraging deer from browsing your landscape.

Do you offer commercial services?

Yes, we provide customized landscape care, risk assessments, and consulting for commercial properties to enhance curb appeal, protect value, and ensure safety.

What is your philosophy regarding environmental sustainability?

We’re reducing our carbon footprint through operational improvements and hybrid/organic programs, and our Consulting Group supports large-scale environmental projects at all levels. Our product selection is guided by agroscience and a three-tiered protocol to ensure environmental safety, efficacy, and cost. All our regulated ingredients are EPA-approved.

How are the ultrasonic devices different from other sound deterrents?

Our proprietary ultrasonic units emit sounds that are piercing to deer but unnoticeable to humans, and they're triggered by motion sensors when deer are nearby, making deer uncomfortable since they cannot listen for predators.

Why is DeerTech® more effective than fencing or repellents alone?

DeerTech®'s three-pronged approach prevents deer from adapting by switching up tactics, while single solutions like fencing or repellents alone allow deer to become accustomed to the deterrent over time.

How often will a specialist visit my property?

A DeerTech® Field Specialist visits your property monthly to observe and adjust your system and treatments based on seasonal changes, weather conditions, and deer behavioral patterns.

What makes the "switch" component important?

The switching component keeps deer unable to adapt by changing smells, sounds, and patterns regularly, since deer are creatures of habit who don't like changes in their environment.

A Three-Pronged Approach to Deer Deterrent

DeerTech®, our patented three-pronged solution to unwanted deer discourages them by creating an environment they perceive as unsafe. Using sound, repellent, and switching the application of those tactics, our solution does not harm deer, pets, people, or plants. It is often more effective than deer fencing or repellent treatments alone.

Sound:

Our proprietary ultrasonic units emit sounds that are piercing to deer, but unnoticeable to humans. The motion sensor triggers the sounds when deer are in proximity, which makes them uncomfortable since they cannot listen for predators. With their hearing compromised, deer are disinclined to browse. The units are unobtrusive, energy efficient, and feature on-site programming capability, allowing your specialist to make adjustments based on the conditions on your landscape.

Treatments:

The combination of foliar deer repellents with ultrasonic sound keeps deer feeling unsafe in your environment. We regularly treat with products which deer find the smell and taste objectionable. Ingredients in scented products aid in making deer feel unsafe and making your property less desirable. Deer deterrent treatments make plants taste undesirable to deer and reduce their interest in your landscaping.

Switch:

Over time, even the first two circles can be penetrated as deer learn to adapt. This is why DeerTech® switches things up to keep deer on their toes and unable to adapt. Deer are creatures of habit. They don’t like changes in their environment. New smells and new sounds scare them. A DeerTech® Field Specialist visits your property monthly to observe and adjust your system and treatments accordingly depending on the season, weather changes, and behavioral changes of deer on your property.

From the first contact with Joshua David in 10/2025, which included a full physical survey of our property, to the final post- work-handshake 1/2026, we have nothing but good to say. Joshua provided a thoughtful, knowledgeable understanding of our trees & plants, walked the property with us, discussed timelines, and emailed us a fully laid out proposal which included a diagram of the trees we...

Your crew did an amazing job trimming our trees, especially the two large oaks. I was a little taken back at the cost… until I watched you r crew at work. I then realized that your price was a bargain… thanks for working with us, Kelly… it’s always a pleasure. Your crew so impressed us that I pre-paid all our tree services for next year.

I recently had a four trunk Ash tree which was very close to my house removed. The crew did an awesome job! They felled the tree with absolutely no damage to any of our shrubs in the vicinity or the house. They also trimmed our White Ash tree to balance the growth for the future, it looks wonderful. They were very professional and polite. Thanks to Ben Zomer and the crew for a job well done.

SavATree showed up right on time as promised, let us know they were here and did the work in a timely fashion for a reasonable price. Initially they planted a 15 gallon ficus and it looked great. Then they offered additional services to prevent bark disease which is what killed my last tree which I accepted and they just came today on time and completed that service to my satisfaction. I...

Kevin and his team of expert arborists did an excellent job taking down my huge rotting Maple tree safely and removing all the wood debris. I am very happy! When the ice and snow melt they will come back to do the final stump and root grinding which I trust will be go equally well. It is also quite a relief to have the tree removed just before a late January major snow and ice event. I...
