Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cockroach exterminator that can kill cockroaches by attaching it to passages that cockroaches like to pass and feeding it to cockroaches.

[Conventional technology]

Conventional methods for exterminating pests include spraying chemicals to kill or keep them away, adding chemicals to bait to kill them, and attracting and capturing them. It is used differently depending on.

In the case of cockroaches, their vitality is extremely strong and it is almost impossible to exterminate them with spray chemicals. Currently, there are traps that combine cockroach attractants and adhesives, and granular poison baits that are commercially available for exterminating cockroaches.

[Problem that the invention attempts to solve]

A cockroach trap is a device in which an attractant containing cockroach pheromones is placed in a box and an adhesive is applied to the box, so that the cockroaches are attracted to the adhesive and become unable to move. Trapping devices have the disadvantage that dead cockroaches remain in the box and are disliked in general households, and because the effectiveness of the attractant is limited, it is necessary to install a large number of traps.

In addition, in the case of poison bait, cockroaches do not die in public places, so they are not disliked by humans, but since the medicine is in the form of particles, it was necessary to put it somewhere. However, by their nature, cockroaches prefer dark places, and they usually run behind cabinets, tables, sinks, etc., especially on the bottom side, facing upwards. It has also been confirmed that cockroaches have a generally fixed path and pass through the same places.
This is thought to be similar to the behavior of ants that teach directions by secreting pheromones. However, it is not possible to place granular food in the path that these cockroaches pass upward, that is, under objects.
Conventional granular drugs had the disadvantage that they could not be installed in appropriate locations.

The present invention was arrived at as a result of intensive study to eliminate the drawbacks of the above-mentioned conventional techniques.

Therefore, an object of the present invention is to provide a cockroach repellent that does not require the disposal of carcasses and can be accurately attached to the passage of cockroaches.

[Means for solving problems]

In order to achieve the above object, the present invention takes the following measures.

(1) For 100 parts by weight of dried potatoes, add 200 to 400 parts of nutrient solution obtained by boiling kelp and bonito flakes in water and filtering them.
parts by weight and 30 to 60 parts by weight of boric acid are added and kneaded.

(2) Fill the resulting paste into an extrudable medicated tube.

The dried potatoes used in the present invention are suitably powdered potatoes used for food, fishing bait, etc.

The nutrient liquid is an aqueous solution containing a smell, taste, etc. that stimulates the appetite of cockroaches, and suitable examples include edible stock, broth of meat, fish, vegetables, etc. In particular, it is preferable to use a dashi stock for udon noodles that is made by boiling water with kelp and bonito flakes and then filtering it.

Commercially available medicinal products can be used as boric acid.
The mixing ratio of these is 200 to 400 parts by weight of nutrient solution and 30 to 60 parts by weight of boric acid to 100 parts by weight of powdered potato.
~50 parts by weight is preferred. The amount of nutrient solution is important as it determines the hardness of the paste; if it is too small, the paste will become hard and difficult to extrude from the tube, and will also be difficult to adhere to the passages of cockroaches. On the other hand, if there is too much, the paste will become too soft and difficult to handle. The amount of boric acid affects the insecticidal effect and is preferably about 10% by weight in the paste. Also, the solubility of boric acid changes significantly depending on the temperature of the water, so the temperature of the nutrient solution when adding boric acid should be between 70℃ and 70℃.
A temperature of about 80°C is preferable.

In addition, preservatives are added to the extent that they do not affect the insecticidal effect.
Colorants, viscosity modifiers, cockroach attractants, etc. may be added.

〔Example〕

Kelp and bonito flakes were added to water in a container, heated, and the kelp was removed before boiling, and after boiling, it was filtered to obtain 400 g of dashi stock. When the temperature of this stock reached 75°C, 100 g of commercially available dried potatoes were added, followed by 50 g of boric acid and kneaded well to obtain a paste.
This paste was filled into a medicated tube to obtain a cockroach repellent contained in a tube.

Figure 1 shows a cockroach repellent containing tubes.
1 is a medicated tube, 2 is a cap, and 3 is a paste. The paste 3 is filled in the medicated tube 1, and the cap 2 is removed and the medicated tube 1 is filled with paste 3.
By pressing , paste 3 can be extruded by an arbitrary amount.

A paste was extruded from the cockroach repellent obtained as described above, and it was applied in soybean-sized pieces to the back of cupboards, the underside of tables, and the sides of sinks, which are thought to be passageways for cockroaches. After three days, the paste dried white and could be easily removed by wiping with a cloth. After doing this for a month, no cockroaches appeared at all. There is a dead cockroach near the sewer.
Only one was found, but it was unclear where it had died or whether it had escaped.

[Effect of idea]

The cockroach repellent of the present invention exhibits the following effects.

(1) Since it is in paste form, it can be applied directly to the back and sides of boards, which are the passageways for cockroaches.

(2) Since it is filled in a medicated tube, it can be applied directly without touching your hands.

(3) Due to the effect of boric acid, cockroaches are reliably exterminated and almost no carcasses are found, so it is suitable for use in cafeterias, general households, etc.
