Description

The present invention relates to a termite collecting container. More specifically, the present invention relates to a termite collecting container, characterized in that at least a part of the container is made of a resin having a total light transmittance of 3.6% or more and 28.6% or less.

Termites are said to be the most destructive structural pests that damage the wood materials of houses and other buildings such as houses and cultural properties. Termites devour nearby wood and other cellulose-containing substances, but these damaged parts are usually hidden inside wood materials and in the soil, so they are often undetectable until the damage becomes serious.
As a practical termite extermination method, a preparation containing an insecticidal active ingredient such as a pyrethroid compound or a neonicotinoid compound is sprayed on a place damaged by termites or a place where termites invade a house. There is a method (for example, Patent Document 1 etc.). However, it is difficult to destroy the entire termite nest with this method. On the other hand, as a termite extermination method for destroying the entire termite nest, a bait method is adopted in which termites are fed with a poison bait agent (bait agent) mixed with an insecticidal active ingredient to exterminate termites (for example, Patent Document 2). etc). This bait method has the advantage of not polluting the environment because it uses a limited amount of chemicals, but has the disadvantage that it takes a long period of several months to destroy termite nests.

It is known that the termite extermination effect of termite poison bait varies greatly depending on the setting of the installation location, and the installation location may be changed many times in search of a place where termites settle. On the other hand, termite poison bait (soil-buried type) used by burying it in the soil is not easy to visually recognize the colonization of termites. Further, even in the termite poison bait (ground-mounted type) used by placing it on the ground, most of the commercially available termite poison bait are containers that do not allow light to pass through, so that the inside cannot be easily visually recognized. In order to confirm the colonization of termites, the soil-buried type digs out the poison bait, opens the containers of the soil-buried type or the ground-mounted type, and checks the inside. However, termites are organisms that dislike light because their eyes are degenerated and are very sensitive to sounds, vibrations, odors, etc., and the established termites escape due to this confirmation behavior, so it is easy to do so. There was a situation that the inside could not be visually recognized and it was not possible to investigate the presence or absence of termite colonization. Under these circumstances, a simple method for confirming that termites have settled has been sought.
Therefore, an object of the present invention is to provide a termite collection container in which it is possible to easily visually recognize that termites have settled.

As a result of intensive research to solve the above problems, the present inventor comprises at least a part of the termite collection container made of a resin having a total light transmittance of 3.6% or more and 28.6% or less. By doing so, it was found that the inside of the termite collection container can be visually recognized while maintaining the fixation of termites without opening (opening the lid) the container, and the above-mentioned problems have been solved.

Specifically, the gist of the present invention is as follows.
1. 1. A termite collecting container, characterized in that at least a part of the container is made of a resin having a total light transmittance of 3.6% or more and 28.6% or less.
2. 1. It is characterized by storing termite poison bait inside. Termite collection container described in.

Since at least a part of the container for collecting termites of the present invention is made of a resin having a total light transmittance of 3.6% or more and 28.6% or less, the inside of the container can be easily visually recognized from that part. It is very practical because it does not require opening (opening) the container. In the termite collection container of the present invention, light enters the inside from a part of the resin having a total light transmittance of 3.6% or more and 28.6% or less, and the inside of the container is not completely shielded from light. However, if the total light transmittance of the portion is within the range of 3.6% or more and 28.6% or less, the termite colonization is maintained, which is an excellent effect.
Further, since the termite collection container of the present invention can easily confirm the settlement of termites, it is easy to install it in a place suitable for termite extermination, and if the termite poison bait is stored inside the container, an excellent termite extermination effect is obtained.
