The Need to Keep Deer at Bay
If you live around areas with deer, the chances of these cute animals visiting you are high. While deer are harmless, they can cause damage to flowers, vegetables, & shrubs.
Some plants they love to munch on include broad-leaved foliage, sweet-tasting plants, apple and cherry trees, arborvitae, daylily, yew, pansies, Indian Hawthorne, azaleas, and roses.
Deer will also feed on plants like hostas, rhododendrons, English ivy, etc. Deer feeding habits and preferences can be a nightmare for gardeners, especially those cultivating such plants.
If this defines your situation, you must address the damage quickly by adopting an effective strategy. Luckily, there are several to choose from.
Are coffee grounds among those? Let’s find out.
Myths on Deer Control
Before applying any home remedy for your deer problem, you must understand several myths about deer control. Some promote using human hair whose odors deers pick up and stay away.
It’s no secret that deer have a strong sense of smell that’s useful in identifying edible plants and detecting predators.
However, there’s no consensus on its efficacy for persons using human hair to deter these pests.
Other commonly held myths include the use of predator urine. While this may sound logical, as deers try their best to avoid predators, there’s no clear proof or evidence that this approach will work.
You’re likely to hear complaints from gardeners who, despite using predator urine, still deal with deer presence and damage.
Some gardeners may also be sold on the use of sound-emitting devices for deer control. However, such may not be as effective, and in cases where they work, your pets may be restless.
The discomfort arising from the constant noise can be unsettling. What more? This might not work long as deer may become used to the sound and not view it as dangerous.
Why Coffee Grounds May Serve to Keep Deer Away
Coffee grounds may keep deer away for several reasons, including its pungent smell. Besides that, coffee is known to contain caffeine.
This can be toxic to deer and other pests when ingested. However, it’s common knowledge that these animals won’t ingest coffee grounds.
This is why it’s applied around the garden and its perimeter to serve as a deterrent.
Another reason coffee grounds may serve as a repellent to deer is its bitter taste. Not many animals will want to feed on such as its taste may be considered unsuitable.
There’s also a naturally-occurring substance known as diterpenes. A lot of plans produce this as a defensive mechanism against plant-feeding animals.
Coming from plants, coffee also contains a percentage of this chemical substance.
Is Coffee Ground Use for Deer Control Backed by Science?
For this guide to make sense, it’s necessary to consider whether repelling deer using coffee grounds is backed by science.
In other words, is there any scientific explanation for why deer would avoid coffee grounds? Here, the answer is simply no. There’s no scientific backing for using coffee grounds for deer control.
In other words, hardly any research or evidence supports this assumption.
While that is true, you’ll come across many articles supporting coffee grounds’ efficacy for deer control. Some other articles counter such assertions.
Whatever the case, there’s no harm in trying. You only need to apply some coffee grounds to your garden area or your home’s perimeter to observe how deer react. This should give you answers.
