Tornado for catching wild boars


Many people are probably worried about the damage to crops caused by wild boars.

The damage caused by wild boars accounts for about 30% of the total amount of damage caused by wildlife, and immediate measures are required.

Therefore, this time, I would like to introduce how to catch wild boars, which is particularly effective in dealing with wild boars. We also explain specific methods of catching them and bits of knowledge, so if you are worried about the damage, please refer to it.

What is the current state of wild boar damage?

Before explaining how wild boars are captured, let's first look at the current state of damage.

According to the Ministry of Agriculture, Forestry and Fisheries' Damage to Farm Products by Wild Birds and Animals Nationwide (FY2018), damage to farm products nationwide by wild birds and animals reached approximately 15.8 billion yen in FY2018. Although it has decreased by about 600 million yen from FY2017, it is still at a high level.

Among them, if you focus only on wild boars, it will be about 4.7 billion yen, accounting for about 30% of the total. This figure is second only to deer, which is about 5.4 billion yen, even if you look at it by bird and beast, and you can see the magnitude of the damage.

Capturing is necessary for wild boar countermeasures

Because wild boars have a high reproductive rate, the population fluctuates greatly from year to year, and if countermeasures are delayed, the damage will quickly become serious. Measures such as installing fences to keep wild boars away and creating environments that make it difficult for wild boars to approach are effective, but as a drastic measure, it is effective to reduce the number of wild boars that cause damage by catching them.

By reducing the population itself, it is important to take measures widely throughout the region.

Wild boar capture method

There are two common methods for catching wild boars: box traps and tying traps. Reference article >> Countermeasures against wild boars - Types of traps

First, let's take a look at the characteristics of each trap.

Capturing with a box trap

A box trap is a trap that traps wild boars by using bait to attract wild boars into the box. Because it uses bait, it has a high catch rate, and does not require as much knowledge or technique as tying traps.

You can also expect to be able to capture multiple traps at once with a single box trap. On the other hand, it is more expensive than tying traps, and it takes a lot of effort to set up and move because it is large and heavy.

I've seen traps with more than half the ceiling open, but they are classified as box traps rather than box traps. It's easy to make mistakes, so it's safe to remember.

Capturing by tying trap

Kukuri traps are traps that use wires to catch the animal's legs or body. Most of the traps are leg-tie traps, which are set in advance along the path the wild boar walks on. Click here for Inohoi's tying trap products>>

Compared to box traps, they are cheaper and can be installed in large numbers, but they require knowledge and techniques to be effective. Also, even after capture, the range of movement of the beast is wide, so it may be dangerous to finish off the captured prey.

Rules to know before catching wild boar

There are rules to follow in advance to catch wild boars.

First of all, as a premise, wild animals such as wild boars are protected by the " Wildlife Protection and Hunting Appropriate Law " (Wildlife Protection Law), and it is not possible to capture them without deviating from laws and regulations. Please note that illegal capture will be punished.

1. Rules for obtaining a trapping license

First of all, in principle, a hunting license is required in order to capture wild birds and animals using traps.

The types of hunting licenses include net hunting licenses, trap hunting licenses, first-class gun hunting licenses, and second-class gun hunting licenses. Also, after obtaining a license, it is necessary to register as a hunter in the prefecture where the trap hunting will be conducted before actually hunting.

There is an examination to obtain a hunting license, which is held about four times a year, usually around July, August, and January. Some local governments have subsidy programs, so it is a good idea to inquire in advance at the department in charge of the government office. The license is valid for 3 years and must be renewed every 3 years.

2. hunting catch rules

The period during which wild animals can be caught by hunting, that is, the hunting period is from November 15th to February 15th of the following year (Hokkaido is from October 1st to January 31st of the following year), and hunting is done during the hunting period. In that case, you will be doing "hunting and capturing".

In the case of wild boar capture, some prefectures extend the hunting season, and some extend the end of the hunting season or start it earlier.

3. Allowed capture rules

If you obtain a trapping license and register as a hunter during the hunting season, you can capture using traps. will be done.

There are two types of permitted capture: harmful wildlife capture and population control capture. * Authority is transferred to the mayors of municipalities by the prefecture.

2-A. Capture of harmful birds and animals

Harmful wildlife capture is intended to prevent or reduce damage when wildlife damage has actually occurred or is likely to occur. As a general rule, it is carried out when it is recognized that damage cannot be prevented even by preventive measures.

In order to capture harmful birds and beasts, it is necessary to submit an application, etc. to the window in advance and have a capture permit issued. Harvesting of pests is not allowed without a permit. For details on the specific flow and procedures, please contact the person in charge at each government office. Some local governments rent traps and provide other support.

2-B. Population control capture

It is a system in which prefectures formulate their own plans (specified wildlife protection and management plans) and systematically implement wildlife management. Example: Wild Boar Management Plan in Miyazaki Prefecture

When adjusting the population of specific wildlife in the target area, it is necessary to obtain a capture permit for the purpose of adjusting the number of specific wildlife.

Tips for catching wild boar

To catch wild boar efficiently, you need to know the knowledge and techniques for it.

Tip 1: Understanding wild boar habitat information and behavior

When choosing a place to set up a trap, it is necessary to assess the infestation of wild boars. Let's understand the behavior of wild boars based on footprints, droppings, traces of mud rubbed on the body, food marks, damage and sighting information.

Reference article >> Tips for increasing the results of tying traps

It is a good idea to set up traps near places where there is a nutaba (where wild boars bathe) or where there are many animal trails, as wild boars are likely to appear frequently.

Tip 2: Choose the right trap for the situation

There are various types of boar traps on the market, ranging from types for beginners to types for advanced users. Even a single spring, which is one of the components of a tying trap, has various hardness and length.

For example, a type with a strong spring has a high capture rate, but it may be difficult for women and elderly people to install it because it requires force to set it on the pipe. If you can't use the trap properly, the catch rate will drop even if you set up a trap, so it's important to choose the best trap for you.

Tip #3: Find a location with a high catch rate

In the case of tying traps, skill is required before stepping on the trap. Wild boars have a habit of commuting on familiar roads, and there are many cases where even the place where they put their feet is the same every time they walk on a road.

Using this habit, when you find a wild boar's footprint, try to erase it and see how it reacts. If there are new footprints after erasing, the trail is considered to be a place with a very high catch rate. In some cases, we were able to capture it immediately by placing a trap around it. Learning these "place identification" techniques will be a shortcut to increasing your catch rate.
