What’s the Difference Between DIY and Professional Deer Repellent?

July 29, 2025

Deer can be a persistent problem for homeowners in New York and New Jersey, often causing significant damage to gardens, trees, and landscaping. Whether it’s grazing on plants or stripping bark from young trees, deer can wreak havoc on your property. To prevent this, many homeowners turn to deer repellent as a solution. But with a range of options available—particularly DIY (Do-It-Yourself) and professional deer repellent services—how do you know which is best for your property?

In this blog, we’ll explore the key differences between DIY deer repellent and professional deer control services, and help you understand why investing in a professional solution could be more effective in protecting your landscape.

1. Ease of Use: DIY vs. Professional Deer Repellent

DIY Deer Repellent:

When it comes to DIY deer repellent, many homeowners opt for store-bought sprays or homemade solutions. These typically involve simple ingredients such as garlic, peppermint oil, or hot pepper.

  • Pros: DIY solutions are generally affordable, and you can purchase them at most local stores or even make them yourself with ingredients from your kitchen.
  • Cons: DIY repellents often require frequent reapplication, especially after rain, watering, or wind. Additionally, some solutions may not work consistently or effectively, depending on the deer population and how accustomed they are to the smell or taste.

Professional Deer Repellent:

Professional deer repellent services, like the ones we provide at Deer Guys, involve expertly applied repellents designed to be both highly effective and long-lasting. Our team uses weather-resistant, eco-friendly formulas that are applied to your landscape, offering consistent protection.

  • Pros: Professional services offer tailored solutions specific to your property and the severity of the deer problem. Our repellents are long-lasting, ensuring you don’t need to reapply as often.
  • Cons: Professional services come at a cost, but this investment ensures optimal results and consistent protection without the hassle of applying repellents yourself.

Conclusion:

While DIY deer repellents are convenient and low-cost, professional deer repellent services are far more effective in providing long-term protection with minimal effort from your side.

2. Effectiveness: DIY vs. Professional Repellents

DIY Deer Repellent:

DIY repellents may work initially, but their effectiveness can quickly fade. Many store-bought repellents contain a mix of natural ingredients, but the formulas may not be as concentrated or potent as professional products. Additionally, DIY methods may not be weather-resistant, requiring frequent reapplication, especially after rain or wind.

  • Effectiveness: DIY repellents may work temporarily, but they often fail to provide comprehensive protection against deer. Deer can also become accustomed to certain smells over time, reducing the effectiveness of the repellent.

Professional Deer Repellent:

Professional deer repellents, like the ones used by Deer Guys, are carefully formulated with strong ingredients such as garlic, rotten eggs, and capsaicin. Our sprays are designed to repel deer by using a combination of scent and taste aversion, which is more difficult for deer to adapt to. Our weather-resistant formulas ensure that the repellent remains effective through rain, snow, and high winds.

  • Effectiveness: Professional repellents are designed to provide consistent, long-term protection. They are applied by trained professionals who know exactly where and how to apply the repellent for maximum effectiveness.

Conclusion:

Professional deer repellents provide more consistent and long-term results compared to DIY options, which often require more frequent reapplication and may not always be as effective.

3. Coverage: DIY vs. Professional Repellent Application

DIY Deer Repellent:

When using DIY repellents, coverage can be inconsistent. Homeowners typically apply repellent only to specific areas of their yard or garden, leading to gaps in protection. Additionally, applying repellent to larger areas like entire lawns, trees, or shrubs can be time-consuming and difficult.

  • Application: DIY products are generally applied by homeowners with little professional knowledge about the best practices for repellent application.}

Professional Deer Repellent:

A professional service like Deer Guys ensures complete and thorough coverage of your entire property. We apply deer repellent sprays to all vulnerable areas, including young trees, shrubs, and flower beds, ensuring that there are no gaps in protection. Our team is trained in strategic application, ensuring the repellent is applied effectively and uniformly.

  • Application: Professionals will handle the entire application process, providing tailored coverage to your specific landscape, and offering a more consistent and comprehensive solution.

Conclusion:

Professional services offer much more complete and thorough coverage, ensuring your entire property is protected, while DIY methods are often limited in scope and effectiveness.

4. Safety and Environmental Impact: DIY vs. Professional Repellent

DIY Deer Repellent:

While many DIY solutions are made from natural ingredients, there are some concerns regarding the safety of homemade solutions, especially if harmful chemicals are used or improperly mixed. Additionally, some store-bought products contain chemicals that may have negative effects on your garden, pets, or the environment.

  • Safety: DIY solutions can be safe if made correctly, but there is a risk of using harmful chemicals or applying them incorrectly, which could harm your plants or pets.

Professional Deer Repellent:

Professional deer repellents used by Deer Guys are eco-friendly, non-toxic, and safe for pets and children. We focus on using natural, sustainable ingredients that won’t harm your plants or the environment. Our sprays also minimize the risk of harm to beneficial insects, animals, or aquatic systems.

  • Safety: Our natural, eco-friendly repellents are both safe for the environment and effective in keeping deer away, giving you peace of mind.

Conclusion:

Professional deer repellents are safer and environmentally-friendly, using natural, non-toxic ingredients that won’t harm your plants or animals.

5. Cost: DIY vs. Professional Deer Repellent

DIY Deer Repellent:

The initial cost of DIY deer repellent products can be much lower than professional services. You can find various sprays, granules, and homemade recipes at affordable prices.

  • Cost-effectiveness: While DIY products are cheaper upfront, they often require frequent reapplications, which can add up over time. Furthermore, their effectiveness may not be as strong as professional solutions, leading to additional costs for replacement plants and repairs.

Professional Deer Repellent:

Professional services come with an initial cost for the application, but the results can save you money in the long run. You won’t have to worry about frequent reapplications, and you’ll avoid costly damage to your plants, trees, and landscape.

  • Long-term savings: The investment in professional services ensures that your landscape stays protected for longer periods, reducing the risk of needing to replace damaged plants and trees.

Conclusion:

While DIY deer repellents are initially cheaper, professional services offer better long-term value by providing consistent protection and preventing costly damage to your property.
