About wildlife control using wolf urine

鳥獣対策 おおかみの尿 ウルフピー

According to the "Current Status and Countermeasures for Wildlife Damage" announced by the Ministry of Agriculture, Forestry and Fisheries in November 2020, the amount of crop damage caused by wild birds and animals in 2018 was 15.8 billion yen. Although there is a downward trend in year-by-year changes, the amount of damage is still large, and continuous bird and beast control measures are essential.

Therefore, various countermeasures against animals that cause damage have appeared. It is an avoidance measure.

What is the countermeasure using wolf urine?

Since ancient times, wolves have been feared as natural enemies of wild animals. Animals that wolves prey on, such as wild boars and deer, are particularly wary and have an instinct to avoid the presence and smell of predators in order to survive.

A countermeasure using wolf urine (wolf pee) is a countermeasure that utilizes these habits as a countermeasure against wild animals. This is an application of the "marking" that wolves use to mark their territories with their urine and body odors, as a countermeasure against pests.

Wild animals such as wild boars and deer are wary of this smell and will not approach the area, so it can be expected to have the effect of repelling pests in the fields.

Also, Wolf Pee does not use artificial additives, so it does not affect the environment of the area where it is used.

For example, when working on pesticide-free cultivation, there is no need to worry about polluting the water used for agricultural products, so it can be said that it is a "nature and animal friendly" wildlife countermeasure. Another feature of Wolf Pie is that it is relatively easy to install.

Wolfpy has fear-inducing properties

So why are wild animals wary of wolf peas? Research papers have been published as to why this is the case.

In 2015, "The Smell of Fear: A Pyrazine Derivative Cocktail P-mix that Induces Fear Derived from Wolf Pee" (Makoto Kashiwayagi, Kazumi Nagata, Sadaharu Miyazono) reported that Wolf Pee caused avoidance and strong fear behavior in animals. We have found that it contains a substance that causes (immobilization).

This substance, called P-mix, stimulates the animal's sense of smell and induces fearful behavior. Animals instinctively perceive the danger of wolves in their surroundings and take avoidance behavior. This is why wolf peas are wary of wild animals.

Some studies have shown that it has no repellent effect.

On the other hand, studies have also been published that Wolfpy has no repellent effect.

According to a report published by the National Agriculture and Food Research Organization, "Wolf pee used for wild boar countermeasures has no repellent effect," when straw that absorbed wolf pea was used to verify the repellent effect against wild boars, no significant significance was found. did not.

There are various theories as to why, although it initially had a repellent effect, the animals got used to it, the installation method of Wolf Pee was not appropriate, and since wolves do not inhabit Japan, animals do not recognize the territory of wolves . Gender is also considered. However, it is difficult to prove it because there is no way to confirm it except by looking at the behavior of the beast.

However, there are many people who say that they have actually been effective as a result of their introduction. It is important to keep in mind that no

How to use Wolf Pee effectively?

So far, we have introduced the effects of Wolf Pee. From here, let's take a look at how to use Wolf Pea more effectively.

Used in conjunction with physical defense

When using Wolf Pea, it is recommended to use it in combination with physical defense such as protective fences and nets.

As already introduced, Wolf Pee contains substances that cause repellent behavior and strong fear behavior, and a certain repellent effect can be seen. However, there are cases where the effect is not recognized (low) depending on the animal's habit and type, so using it in combination with physical defense can further enhance the effect.

Let's increase the countermeasure effect by skillfully combining Wolf Pee and physical defense.

Finely adjust the space width and height of the installation location

Finely adjusting the installation location is also one of the ways to increase the effect of Wolf Pie. Specifically, place Wolf Pies around the area you want to stop the damage. Also, let's adjust the space width to be installed according to the size of the animal.

〇Large animals such as wild boars, deer, and bears: installed every 5-6m

Small animals such as monkeys and palm civets: installed every 3 to 4 m

Narrowing the gap width will increase the effect especially in places where there is a lot of intrusion. At the same time, it is recommended to set the height of the wolf pea with the height of the nose of the target animal in mind.

Install to block the animal trail

If you know the animal path that the animal is entering, place a Wolf Pie to block the animal path. A familiar animal trail is a place where animals can easily detect abnormalities. Placing Wolf Pies in these areas will increase their effectiveness.

Take regular replenishment and rain protection measures

Since Wolfpea is a liquid, it evaporates. If it evaporates completely, it may reduce its effectiveness, so replenish it in about a month. Also, taking measures to protect against rain is a good way to increase the continuous effect.

When the concentration of urine drops due to rain, the effect of odor is also reduced. Take measures such as covering the top of the installation location with a rain cover or using aluminum foil.
