Abstract

PURPOSE:An agent for attracting and killing cockroaches that is prepared by kneading roasted wheat flour, boric acid, carrier powder, flavors and milk and forming the mixture into balls, pellets or beads, thus having high action of attracting and killing cockroaches, because of its high palatability. CONSTITUTION:The objective agent is obtained by using 18-21wt% of roasted wheat flour, 40-55wt% of boric acid, 3-5wt% of carrier powder such as kieselguhr, 3-6wt% of sweetening such as sugar, 3-6% of flavors such as crushed vegetables, e.g., onion not dried, and 15-25wt% of milk. Since this agent is relatively low in evaporation-off of a variety of odor components which attract cockroaches and of water, long-term and durative use is possible without deterioration in its effect. The agent is prepared, e.g., by adding crushed vegetables and milk to a mixture of powders of boric acid and the carrier to effect sufficient kneading, further adding a mixture of roasted wheat flour and sugar intermittently to the product under kneading.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cockroach attractant that provides a high degree of palatability and is intended for cockroaches with enhanced induction and insecticidal effects.

Cockroaches are insects that are also called aphids, and there are 20 of them worldwide.
It is said that there are over 00 different species living there, but almost all of them prefer moist places and are active at night to feed.

In particular, many cockroaches like filth, so they are considered important sanitary pests, and many methods have been proposed since ancient times to attract and kill cockroaches. Among these methods, a relatively familiar method involves mixing vegetables such as potatoes and eggplants with boric acid and placing the mixture on newspaper, etc.; however, in this method, the main chemical is The dispersibility of boric acid is poor, and the cockroach induction is low, so as a natural result, there is little hope for its killing effect. In contrast, synthetic insecticides based on insecticidal agents such as Diedrin have recently become popular on the market, but these synthetic insecticides are not as palatable to cockroaches, so they are not as effective at attracting cockroaches. There is an inconvenience σ that it cannot be used casually because there are too many precautions and restrictions. .

This invention was developed in light of the current situation, and is a cockroach attractant consisting of roasted wheat flour, boric acid powder, carrier powder, a sweetener, a flavoring agent such as crushed vegetables, and milk. It provides: The details are described below.

First, the roasted wheat flour in the present invention is flour that has been roasted to a golden brown using a heating plate or a sieve, and may also be flour that has been pulverized from roasted wheat grains. The aroma emitted by roasted flour plays a very important role in attracting cockroaches.

Boric acid (usually in the form of scale-like crystals) is the main insecticidal agent of this invention, and a carrier powder is used in combination to uniformly disperse this main agent. Here, it is desirable that the carrier powder has a encapsulating ability not only on its surface but also inside it, so it is preferable to use one that has a pore structure inside, such as diatomaceous earth, and is inexpensive and easily available.

In addition, sweeteners and crushed vegetables are made up of foods that cockroaches especially like to eat.Sugars are used as sweeteners, and crushed onions are used as crushed vegetables, but they are not effective in small amounts. It can be recommended as the most preferred method because it is large and requires only 60% of manpower.

(Furthermore, milk is used to provide the moisture necessary for kneading the various ingredients mentioned above), and even if it is skim milk, it is also fat-containing milk (regular commercially available milk has a milk fat content of 3. % or more), but fat-containing milk is preferable from the viewpoint of cockroach palatability.

When blending these various materials, 40 to 55% of boron powder (by weight, the same applies hereinafter), 3 to 5% of carrier powder,
Approximate blending ratio of 18-21% roasted wheat flour, 3-6% sugar, 3-6% crushed vegetables (hydrated), and 15-25% milk (just rub. When the amount is less than the previous statement, the insecticidal effect is small, and when the amount exceeds the above amount, the increasing effect is not significant, and other ingredients must be added. Carrier powder C is not preferable because it limits the self-content of the material.
If the amount of roasted lJ/wheat flour is smaller than the lower limit value,
The effect of adding wheat flour is small, and if the amount exceeds the upper limit, 3
i. "Effect of coating amount and influence on the amount of other materials added, etc.", no significant advantages were observed, and sugars and 1Jjf,
6'h Amount of Ilmus (even if it is stiff, if the amount is less than the lower limit, the effect will be small; conversely, even if the amount is increased beyond the upper limit, no effect can be expected from increasing the amount, and milk is less effective than the previous limit. Manufactured with appropriate shape retention by kneading various ingredients.
JI:O (This is because the amount that can be obtained by performing 1 is sufficient.

The cockroach attractant of this invention can be produced by a method such as poisoning. First, boric acid powder and Kichiyotai powder are mixed in advance in powder form, and crushed vegetables and milk are added to this and mixed together thoroughly.8Meanwhile, roasted flour and sugar are thoroughly mixed. When this mixture is kneaded while being intermittently added to the above-mentioned mixture, the kneaded material, which is initially wet, gradually becomes cake-like, and finally becomes a hard lump that can be molded into a compressed shape. The composition is as follows. Of course, the order of addition of each material is not limited to the above example, but if a moldable composition is obtained in this way, it can be shaped into dumplings, pellets, or beads. Shape it into a suitable size and store it in a container. Here, the container is a plastic bag or a plastic container, etc.
Coating the inside of the container with oil and fat to increase the attraction of cockroaches and preventing the growth of mold, and storing it in a sealed state up to the use surface A'fJ with a seal with heat-on-roll or adhesive desolation, etc. This is preferable because it can prevent childish underdevelopment.

As stated above, the cockroach attractant of the present invention is prepared by making full use of the characteristics of foods and food additives that cockroaches like, and after attracting cockroaches, kills them by passing boric acid. Goya can be easily attracted to and killed by leaving them in the aisles for goya, or in places where vegetables and seasonings are stored. Furthermore, when using the attractant of this invention, it is rare for the goya species to stay in the excavated soil and die, but in most cases they die in the container or near the attractant, so it is extremely difficult to identify the carcasses. It's easy. In addition, the attractant of this invention has a relatively low transpiration rate of various aromas and moisture that are essential for attracting goyas, so it can withstand long-term use without causing low F. It can be said that the moral significance of this is extremely large.

〔Example〕

Mix 50% boric acid (x beak-shaped powder), 4% diatomaceous earth powder, 19% wheat flour (anhydrous heated powder), 4% sugar, 4% crushed onion (still hydrated) and 19% commercially available milk, and make a spider. The combined 50 g pellets were placed in a Petri dish coated with seed oil on the inside and placed in the corner of the kitchen sink. As a result, after 3 days, the remains of 20 cockroaches were found within a radius of approximately 5oCm from the container, and no dead cockroaches were found on the container.

In addition, although the composition was left for another year, only a slight amount of mold formed and no significant decrease in efficacy was observed. It has been confirmed that it is extremely easy to use and does not require any special attention.
