JPS5967209A - Cockroach killer - Google Patents

Abstract

PURPOSE:A cockroach killer that contains feeding substances, boric acid and onion, thus showing large controlling effect, keeping the effect for a long period of time and being produced inexpensively. CONSTITUTION:The cockroach killer is made by using feeding substances such as rice bran, rice flour, wheat flour, fish powder, bone powder, powdered milk, milk butter or sugar, boric acid and onion. Onion acts as an attractant and/ or binder, however, other attractants such as aliphatic, alicyclic or aromatic hydrocarbon, alcohol, ether, amine, aldehyde, ester, carboxylic acid or other synthetic attractants may be combined. The resultant insecticide is well kneaded, made into balls of 30-40mm. diameter and 10-15mm. thickness, then dried. When the balls are placed at several placed in the house, cockroaches will haunt nowhere and the insecticidal effect is kept for more than 1 year.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cockroach insecticide which mainly uses onion as an attractant and/or a solidifying agent, and which is blended with boric acid, a feeding substance, and the like.

Known methods for exterminating cockroaches include using insecticides, using repellents, and using attractants and traps in combination. Conventionally, insecticidal methods using organic chlorine agents were known, but insecticides with strong residual effects, such as DDT, were used.
Although it is extremely effective to exterminate cockroaches by spraying organic chlorine agents such as BHC in areas where cockroaches often inhabit, such as kitchens, dining rooms, and bathrooms, it is currently not recommended as it may be toxic to humans. Use is prohibited. Today, less toxic organophosphorus insecticides are used, and although they have insecticidal power when sprayed directly against cockroaches, they have a small residual effect and can exterminate cockroaches that cannot be seen by the human eye. I can't do that.

One method of using an attractant and a trap is to put bait in a push-type trap and catch 111i, or to coat the trap with adhesive so that the cockroaches inside will stick to it. Adhesive methods are known that capture cockroaches by trapping them in their legs and preventing them from escaping, but although these methods can get rid of cockroaches that have entered the trap, they can also prevent the growth of cockroaches. It has no effect on preventing the proliferation of cockroaches and can only get rid of some of the cockroaches inside the house. Furthermore, when many traps are installed indoors, they have the disadvantage that they interfere with housework, walking, etc.

Further, although these conventional cockroach extermination methods can be expected to have immediate and temporary effects, they do not have long-term extermination effects.

The present inventor conducted intensive research to overcome the above-mentioned drawbacks, and as a result, arrived at the present invention. The present invention exterminates cockroaches from indoors by placing them in several locations indoors,
The present invention provides a cockroach insecticide whose effect lasts for a long period of time, and is characterized by containing a feeding substance, boric acid, and an attractant, and using onion as an attractant and/or an assimilating agent. .

That is, the cockroach insecticide of the present invention is made by solidifying a feeding substance, which is a favorite food of cockroaches, and boric acid, which is repellent and ingested by cockroaches and has an insecticidal effect, using onion, and has no attracting properties. There are cockroaches (■ Toshiyazuku, insecticidal J) that have been present in humans for a long time.

The feeding substances in the cockroach insecticide of the present invention include grains such as rice bran, rice flour, wheat flour, and corn flour;
Mention may be made of animal foods such as fishmeal, powdered milk, butter or milk, or sugar. In addition to onions, attractants include synthetic attractants, such as aliphatic, alicyclic, aromatic hydrocarbons, or their derivatives such as alcohols, ethers, ketones, amines, aldehydes, esters, carboxylic acids, etc. It can also be combined with the body.

The cockroach insecticide of the present invention is prepared by crushing onions, for example, with a mixer, adding boric acid, feeding substances, etc., and kneading them well to obtain a powder with a diameter of about 30 to 40 mm. I11, thickness about 10~],, l) 11
After forming into the shape of 11 dangos, it can be dried and solidified for decoration. Therefore, it can be installed at an extremely low cost, and by placing this cockroach insecticide in several places indoors, it has an amazing exterminating effect: cockroaches will no longer appear anywhere in the house. There is. Moreover, it has the excellent feature that its insecticidal effect lasts for more than one year or two. If onions were not used, but boric acid, a feeding substance, and water were kneaded and dried to solidify, a solid product similar in appearance to the embodiments of the present invention could be obtained, but it is clear from the experiments described below. Therefore, it is impossible to expect the same effect as the wooden invention. This is thought to be due to the attractiveness of the onion due to its pungent odor and the solidifying power of the substance 4 in the onion fibers.

EXAMPLES Below, in order to explain the present invention in more detail, examples of the present invention and comparative experiments with comparative sample examples will be described.

(Example 1) Grind 400g of onion with a mixer, and add this and 500g of boric acid.
, knead 125g of flour, 15g of sugar, and 10g of milk,
Divide this into about 50 dumpling-shaped pieces, each weighing about 20g. These dumpling-shaped lumps are thoroughly dried and solidified in direct sunlight for three days. Let's call this Dango A.

(Example 2) Grind 400g of onion with a mixer, and add this and 400g of boric acid.
, knead 130 g of rice bran, 17 g of sugar, and 13 g of milk, and divide the mixture to make about 50 tons of dumpling-shaped lumps each weighing about 20 g. These dumpling-shaped lumps were placed in a hot air dryer and dried and solidified at 80° C. for 10 hours. Let's call this Dango B.

(Comparative sample example) 1500g of wheat, 500g of boric acid, and 15g of sugar were mixed well, 15g of milk and 200g of water were added to make it viscous, and this was divided into 20g/dango-shaped lumps. Make 50 pieces. These dumpling-shaped lumps are placed in a hot air dryer and dried at 80° C. for 10 hours to solidify. This is called Dango R.

Cockroach insecticidal effect experiment (Experiment 1
) and a sustained cockroach insecticidal effect experiment (experiment 2).

(Experiment 1) Dango A is placed in a plastic container approximately 30cm cubic in size.
, R, C without mataba dumplings, about 5 cc of water, and food (
Powdered cockroach feed) and cockroaches were placed in the container, and the number of days elapsed and the number of dead insects were observed. The results are shown in Table 1. According to this, the cockroach insecticide according to the present invention has an excellent insecticidal effect and exhibits the insecticidal effect earlier than the comparative sample.

(Experiment 2) An experiment similar to Experiment 1 was conducted every time a certain period of time elapsed after the production of dumplings. The results are shown in Table 2. According to this, the cockroach insecticide according to the present invention has an excellent insecticidal effect over a long period of time, and exhibits an insecticidal effect for a long period of time compared to the comparative sample.
