Combination of Odors and Tastes

A mix of odor and taste deterrents is used in almost all repellents. As a result, most deer deterrent products have a foul odor, at least until they dry.

By consistently determining the perfect combination of deterrents, it can be an effective repellent to keep the deers away from your plants. That way you can be sure that your plants are secured in the garden.

This finding was a huge discovery that became popular with some repellent manufacturers worldwide, making it also a big trend for most gardeners.

How Does It Work?

There are a plethora of excellent deer repellents and deterrents on the market, but their effects are almost entirely dependent on how they are applied. If you want these repellents to operate well, you must be consistent in your application.

Apply your homemade deer repellent or any commercial product you have after the morning dew or any rain has dried completely around your plants but make sure not to apply it in areas where the scent could reach both you and your neighbors. 

Just make sure to spray the repellent to the entire plant, including the leaves, stems, fruits, and make it smell and taste too bad for the deer so they won’t dare to eat it, nor come near your garden.

How Long Does Deer Repellent Last

Some Commercial deer repellent products protect for up to four to six weeks that are not degraded by rain. Some also last up to 2 months before another application and do not wash off easily.

About homemade deer repellents, some homemade repellents last up to two weeks. Bobvila suggests reapplying the homemade deer repellent weekly and after rainfall. If you make your yard unappealing from the start, they’ll seek out more favorable grazing ground and may avoid your property.

Will Deer Repellent Keeps Other Animals Away

Many deer repellents aren’t just for deers; they also act effectively on other animals. Other pests, such as rabbits, raccoons, skunks, and rodents, are deterred by taste and scent-based repellents. They pretty much hate the pungent smell, signalling them that the plant isn’t edible and may pose danger. 

You can also make repellent based on cayenne pepper, which emits a strong smell that will aid in keeping most of the herbivore animals away from your plants. 

And because some pets perceive smaller animals as a threat or potential predator, they can also help keep wildlife away. Makes everything much easier when you have pets around the property.

Safety Tips To Keep Deers From Your Garden

Choose Deer-Resistant Garden Plants

Deers are known to eat almost anything, especially when they get hungry. According to, deers love to eat foods that they don’t get to eat all the time. 

Fruits and nuts are favorites of deer. In addition to acorns, they enjoy pecans, hickory nuts, beechnut acorns, apples, blueberries, blackberries, and persimmons in addition to acorns. Deer will occasionally go into yards to eat flowers, vegetables, and decorative plants.

Build Garden Fences Around Your Garden

A fence surrounding the garden is the most effective method of repelling deer. A fence should reach partially underground and not have gaps where deer can squeeze through or crawl under to keep deers out. Make sure that the garden fence you will build is high enough to prevent deers from jumping through.

Use Deer Repellent Sprays

Applying deer repellent sprays in your plants produces strong smells that will keep the deers from eating your plants. Deers dislike strong odors because they have a very sensitive smell, and it also disables them from detecting predators.

Scatter Human Hair Your Garden

Most deers are afraid once they smell humans and will stay away from areas where they perceive that humans are present. That is why if you have some hair clippings, scatter them around your garden equally. 

Scare The Deers Away

There are tons of possible ways to scare the deers away. One way is by placing unfamiliar objects around your garden. Scarecrows, sundials, and other garden ornaments, especially those with moveable elements, make deer nervous, even if they aren’t usually appealing.
