“Emailed ohDeer and got a response within 2 hours. A technician was in the area and was at our house the same morning. Diagnosed our issues with deer eating the arborvitae and was able to treat our trees (and our neighbor’s trees as well) on the spot. We were quoted a reasonable price for treatments. Very happy the spray is all natural. Couldn’t ask for better, more professional service. Relieved that we found a solution to prevent the deer from eating our trees.

Before we started with OhDEER, our property was ravaged by deer. I was using deer repellant from Lowes (smells terrible),  sonic repellent, and dried deers blood. Nothing was working. Then we found OhDEER . Least season was the first time in 5 years we experienced full blooms in our yard. I literally forgot we planted some stuff that grew. They are also super easy to work with. All billing happens digitally and can be set to automatic. The products they use actually smells good.I highly recommend OhDEER.

Choose the Right Deer Repellent Plan for Your Property

Every landscape is different. Our programs are structured around seasonal browsing patterns and the level of deer pressure on your property.

SPRING/SUMMER CONTROL

Designed to protect tender new growth, blooms, shrubs, and perennials during peak feeding months. Treatments begin in early spring as plants emerge and continue through summer to reduce repeated browsing.

Every three weeks, spring–summer

Best for properties vulnerable to winter browsing pressure.

Every three weeks, fall–winter

ANNUAL CONTROL (Most Popular!)

Deer don’t follow a calendar. Annual Control combines seasonal treatments into one uninterrupted Deer Repellent plan for properties with ongoing activity.

Why is ohDEER repellent so … repellent to deer?

Think of our repellent like a bitter coating used to wean a baby from a pacifier; it’s safe but highly unpleasant to taste. Deer will quickly learn to forage in the St. Charles woods instead of your backyard. This non-toxic, plant-based blend is highly effective for repellent services while staying safe for children, pets, and local river ecosystems. We rotate our active ingredients so the adaptive Missouri deer never get used to the deterrent.

Frequently Asked Questions

Are deer deterrent sprays genuinely effective in preventing damage? toggle answer box

Yes, deer deterrent sprays can be highly effective when used correctly and consistently, especially if they’re formulated with strong, nontoxic components like egg solids, garlic, and essential oils. The key is ensuring that the product produces unpleasant tastes and odors without harming plants, people, or pets. A high-quality deer repellent service, such as ohDEER’s, also rotates different repellents or scents occasionally, preventing deer from adapting to a single formula. However, even the best sprays have limitations. Heavy rain may wash away some potency, and rapid new plant growth won’t have the protectant yet. That’s why most deer repellent solutions require reapplication every few weeks to maintain full coverage. For homeowners facing particularly large deer populations, combining sprays with other tactics—like fencing, pruning, or scary devices—can yield even better results. Ultimately, while no deterrent is 100% foolproof short of a tall fence, a professionally managed spray service can significantly reduce deer browsing and preserve the beauty of your landscape.

Which deer deterrent approaches do deer really dislike the most? toggle answer box

Deer absolutely hate methods that combine offensive smells, unpleasant tastes, and physical barriers. The most effective deer control services focus on layering multiple deterrents to bombard deer’s senses. Offensive-tasting foliage (coated in strong ingredients like garlic, egg solids, and pepper) is typically the first line of defense. Smells that confuse or alarm them—like peppermint or other potent essential oils—add a second layer. Physical tactics, such as fencing, present a tangible obstacle. An eight-foot fence blocks deer from hopping into your yard. Smaller but strategically placed fences, netting, or spiky ground barriers can also disrupt their feeding routes. Additionally, motion-activated devices that startle deer with sudden sounds or bursts of water can be highly off-putting. Deer respond poorly to unpredictability—constantly rotated scents, random sprinklers, or abrupt loud noises. By mixing these techniques, you maximize discomfort and encourage deer to abandon your property for better foraging spots. ohDEER’s all-natural deer repellent solutions excel by combining relentless repellent sprays with a customized schedule to keep deer guessing year-round.

What odors do deer find most offensive? toggle answer box

Deer are known to have an aversion to strong, pungent odors that humans often find pleasant or at least tolerable. Chief among these are garlic, peppermint, and hot peppers like cayenne. Any combination of these scents can be especially effective—garlic and peppermint oil, for instance, form the backbone of many all-natural deer repellent solutions, including ohDEER’s. Additionally, deer loathe the smell of decaying protein, which is why egg solids frequently appear in professional-grade sprays. This odor mimics the presence of predators or other threats, causing deer to become uneasy and search elsewhere for safer feeding grounds. Many herbs—sage, rosemary, lavender—also emit potent fragrances that disrupt a deer’s normal feeding patterns. It’s important to note that while deer might detest these smells, a strong hunger drive (e.g., in winter or drought conditions) can make them less picky. That’s why consistent application of a professional deer repellent service is crucial, ensuring the scents remain strong enough to thwart even the hungriest visitors.

Which types of surfaces do deer generally avoid stepping on? toggle answer box

Deer generally avoid surfaces that feel unstable, noisy, or otherwise hazardous to traverse. Crushed gravel or sharp stone pathways can discourage deer from cutting across certain parts of your yard, as the uneven ground and crunching noise make them uneasy. Mulch layered thickly can have a mildly deterrent effect for similar reasons—though mulch alone usually isn’t enough to keep determined deer away. Some gardeners find success with physical ground barriers like netting, low chicken wire, or prickly branches arranged around delicate plants. The idea is to create a tactile environment that deer dislike and prefer to bypass. Additionally, motion-activated sprinklers or lights positioned along walkways can startle deer, making them uncomfortable to proceed further. Though these measures can help in conjunction with deer repellent solutions, they’re typically partial solutions rather than comprehensive strategies. For robust, consistent deer control, it’s best to combine uncomfortable ground surfaces with other deterrents—like natural sprays and strategic planting. This layered approach tackles multiple senses (touch, sight, smell, and taste) and yields stronger, more reliable results.

When is the optimal time to apply deer spray? toggle answer box

Timing can be crucial when establishing a deer repellent service. Generally, the best practice is to start applying deer repellent before deer develop a feeding habit on your property. In spring, spray new growth early, since young shoots and blossoms are particularly attractive to deer. This preemptive strike helps condition deer to avoid your yard from the get-go. You’ll also want to maintain consistent treatments throughout summer and early fall, especially if you have a garden full of colorful flowers or produce. As autumn transitions to winter, deer often shift to consuming woody stems, bark, and evergreen foliage. Regular applications—about every three weeks—can protect vulnerable trees and shrubs even in cold months. Some choose to continue treatments year-round with ohDEER’s deer control services, particularly if they enjoy winter gardening or have newly planted ornamentals. Ultimately, the “right time” is whenever deer have anything to eat in your yard, ensuring you always stay ahead of their seasonal feeding patterns. Your local ohDEER expert will help you evaluate your landscape and recommend the best treatment schedule for your specific property and region.

How long do the protective effects of deer spray typically last? toggle answer box

The longevity of a deer spray’s effectiveness depends on factors like weather conditions, the product’s formulation, and how quickly new plant growth emerges. High-quality, professional-grade deer repellent solutions often remain potent for two to three weeks, although some may last longer. At ohDEER, we typically recommend reapplication every three weeks to ensure continuous coverage. Heavy rainfall or prolonged moisture can gradually dilute the active ingredients. However, an effective formula usually withstands moderate rain without completely washing away. As plants grow, new leaves won’t have the same protective coating as older foliage, making regular treatments essential. By sticking to a consistent schedule, you’ll keep fresh plant material coated, ensuring deer consistently encounter unpleasant tastes and smells. Other factors—like temperature and the deer’s hunger level—also play a role. Extremely hungry deer might ignore mild repellents, so it’s crucial to use a strong product that deer recognize and avoid. Ultimately, a well-maintained deer spray regimen can keep your property off the menu year-round.

Which deer repellent offers the highest success rate? toggle answer box

The most effective deer repellent is one that targets deer’s natural aversions—particularly taste and smell—while remaining safe for the environment, people, and pets. Products that use ingredients like egg solids, garlic, pepper, and plant-based oils (such as peppermint) taste foul and create strong, persistent odors that deer actively avoid. Additionally, rotating formula components helps prevent deer from developing a tolerance, which is a common issue with single-ingredient repellents. At ohDEER, our deer repellent solutions blend multiple defensive agents into a single, powerful solution. This multi-pronged approach capitalizes on sensitivity to both smell and taste, offering a consistent deterrent. Moreover, the spray adheres to leaves and stems over several weeks, providing ongoing coverage even through light rain. Ultimately, combining a potent formula with strategic application intervals ensures the highest success rate. Physical barriers like tall fences remain the only 100% exclusion method, but they can be costly and visually unappealing. For most homeowners, a comprehensive spray regimen provides a more practical, aesthetically pleasing option.

Which scents are most effective at driving deer away from your property? toggle answer box

Deer rely heavily on their sense of smell for both foraging and predator avoidance, making scent-based tactics highly effective in deer control services. Strong-smelling substances like garlic, peppermint oil, cloves, and various herbal extracts can overwhelm a deer’s sensitive nose. ohDEER’s deer repellent service blends these pungent ingredients into a spray that coats your plants, leaving behind an odor deer find unappetizing—while remaining pleasant or neutral to humans. Herbs such as lavender, sage, and rosemary are also renowned for their strong aromas. Planting them in strategic “barriers” around your more delicate flowers or veggies is a form of interplanting that can further discourage deer from wandering deeper into your garden. Other methods might include placing homemade sachets of essential oils or garlic around your yard, although these can be less reliable than professional-grade sprays. Overall, scent-based repellents offer a safe, non-toxic alternative that keeps deer at bay without the need for fences or chemicals.

What are the best ways to keep deer at bay naturally? toggle answer box

Repelling deer naturally involves leveraging their keen sense of taste and smell to create an environment they find unappealing. Plant-based sprays, like those used in ohDEER’s deer repellent solutions, can coat leaves and stems with safe but bitter or pungent flavors deer want to avoid. You may also interplant strongly perfumed flowers and herbs—like lavender, bee balm, or rosemary—around your most vulnerable plants to act as a fragrant wall of defense. Beyond sprays and planting choices, additional measures like installing physical barriers or pruning lower branches can reduce easy feeding opportunities for deer. Some homeowners even set up motion-activated sprinklers or lights to startle them away. By combining multiple strategies—such as dedicated repellents, strategic plantings, and habitat modifications—you create layers of deterrence that make your yard a less appealing dining destination. The key is consistency: have ohDEER reapply sprays per the recommended schedule, refresh any hanging sachets, and maintain whatever fencing or pruning regime you use. This holistic, natural method preserves your garden’s charm and keeps deer out without resorting to harsh chemicals.
