Description

[Detailed Description of the Invention] The invention relates to an exterminator for cockroaches that live in kitchens, especially in humid cupboards and water sheds. The object of the present invention is to provide a product that has the dual effects of repelling cockroaches by keeping them away and killing cockroaches that approach against the repellent effect.

The characteristic composition of the uninvented cockroach exterminator that was made to achieve the above object is boric acid or a boric acid compound as an active ingredient, and a supplement containing flour and yeast that maintains this active ingredient and attracts cockroaches to feed. It consists of the following ingredients.

The effects of the cockroach repellent according to the present invention having such characteristics are as follows.

In other words, the individual effects of each ingredient, such as the feeding-inducing effect of flour, etc., and the repellent and insecticidal effects of boric acid or boric acid compounds, keep cockroaches away from places where cleanliness and hygiene management is required, such as food and tableware. While fully exerting the repellent effect of keeping the cockroaches close to the area as much as possible, it also induces the cockroaches that come close to the above-mentioned area to feed, and exhibits the insecticidal effect that accompanies feeding, resulting in an overall cockroach extermination effect. We were able to make the most of it.

A non-inventive embodiment will be described in detail.

Boric acid or a boric acid compound as an active ingredient, and an auxiliary ingredient consisting of flour, yeast, and beer that promotes yeast activity to maintain this active ingredient and induce cockroach feeding. ~75
% and dried to form a candy-like solid substance.

The results of a feeding toxicity test on German cockroaches using the above-mentioned cockroach repellent are shown below.

The test method is as follows. In other words, 19 to 20 female adult German cockroaches (raised for many years using artificial feed) that had been lightly anesthetized with carbon dioxide gas were placed in a glass container along with the above-mentioned cockroach repellent, and a wire mesh was placed on the top of the container. Put the lid on, place some water-soaked absorbent cotton on top, and keep it hydrated for 25 minutes to keep it hydrated.
The number of live and dead animals was observed and recorded every 24 hours for 8 days in a constant temperature room at ℃. As a comparative example, observations and records were also made under the same conditions as above, with one piece of normal feed added instead of the pesticide. From Table 1 showing the above observation record results, the following can be concluded.

(G) The insecticidal effect was seen two days after the start of the test, and the insecticidal rate reached approximately 80 crabs eight days later. In addition, a small number of growth problems were confirmed. The reason for this is thought to be that they avoided insecticides and did not eat them.

The following is a different example, but as a usage form,
It can be made into a thin plate and attached to a wall with adhesive, or it can be placed in a decorative case.
