Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a repellent for animals and birds, and more specifically, it has an excellent repellent effect on animals and birds, particularly dogs, cats, pigeons, rats, etc. The present invention relates to a repellent for animals and birds that is mainly composed of highly safe compounds and can be used with less concern about human health.

[Conventional technology]

In recent years, there has been an increase in incidents of bite accidents caused by stray dogs, damage caused by rats inside buildings, large bags of municipal waste, prey eaten by cats, torn bags, and damage caused by crows after sowing soybeans, etc. Studies and research on methods and formulations to prevent this have begun.

Conventionally, as a repellent for animals and birds, compositions containing methyl nonyl ketone and/or methyl phenyl ketone as main components and one or more of green leaf aldehyde, green leaf alcohol, cinnamaldehyde, and cinnamic alcohol (especially JP-A-5725521), compositions containing diethyltoluamide and/or menthol as main components (JP-A-142903), allyl isothiocyanate, L-nonyl lactone or citral are mixed and processed during polyethylene film molding. A composition containing limonene, linalool, and citral as main components (Japanese Patent Application Laid-open No. 1-110)
No. 602) and the like have been proposed.

[Problem to be solved by the invention]

However, when the above-mentioned repellents are actually used, they have the disadvantage that they are not sufficiently effective and their duration is short. For example, a repellent containing diethyltoluamide as a main component has an initial effect but is not sustainable, which poses a major problem as a commercial product.

In addition, many of the preparations currently on the market are based on essential oils extracted from plant-based sources, and although they are effective to some extent for cats, they are not yet fully satisfied.
It is also considerably less effective against dogs, birds, and rodents.

Therefore, it is desired to develop a product that has a strong repellent effect on dogs, cats, birds, rats, etc. and that continues to be effective for a long period of time.

The present invention was made in view of the above circumstances, and its purpose is to provide a highly safe animal and bird repellent that has an excellent repellent effect on animals and birds and has a long duration of effect. Our goal is to provide the following.

[Means to solve the problem]

According to the present invention, in order to achieve the above-mentioned object, the active ingredient is a deodorant having a deodorizing effect that deodorizes or modifies the body odor of animals and birds, human urine odor, feed odor, and living environment odor. There is provided a beast and bird repellent characterized by the following.

Furthermore, according to the present invention, the animal and bird repellent is characterized in that the active ingredient is one or more of each of the deodorant and a sensory stimulant that stimulates the skin, mucous membrane, etc. that sense taste, odor, pain, etc. agent is provided.

As the above-mentioned deodorant, terpenes such as cineole, pinene, camphor oil, and citronellal, and tannins such as mimosa tannin, keprathio tannin, and pentadium tannin are particularly effective. In addition, flavonoids such as chalcones, flavonols, and infravones, steroids such as sterine, bile acids, and steroid saponins, amino acids, organic acids such as ascorbic acid, malic acid, and humic acid, and enzymes originating from filamentous fungi and actinomycetes. Deodorants are also effective.

On the other hand, the sensory stimulants include alcohols such as nonyl alcohol and decyl alcohol, cyclic ketones such as methyl phenyl ketone, phenols such as cresol and creosote, fused heterocyclic compounds such as quinoline, and cinnamic aldehyde. Aromatic aldehydes such as, esters such as methyl salicylate, isobutyl acetate, benzyl acetate, sulfur compounds such as coffee mercaptan, allyl isothianate, garlic ura (allyl sulfide), onion extract, aromas such as dinitrosocresol, etc. Group chlorine compounds,
Organic acids such as acetic acid and formic acid are particularly effective.

[Operation and mode of the invention]

As a result of many years of research into the repellent effects of animals and birds, the present inventors have discovered that by conversely utilizing the instinctive physiological functions and behaviors of each individual animal to secure its territory, It has been found that an effective repellent effect can be obtained and can be maintained for a long period of time.

That is, the first aspect of the present invention is characterized in that the active ingredient is a deodorant having the effect of deodorizing or modifying odors (generally referred to as odor changing). To explain the effect of this deodorant, it purifies the environment by deodorizing or modifying the animal's own body odor, the familiar environmental odor, human urine odor, feed odor, etc.
It completely changes the atmosphere of the living environment where the animal feels safe, makes it feel strange, gives a feeling of confusion, fear, awe, disgust, etc., and causes a mental and psychological repellent effect.
Furthermore, it has the secondary effect of suppressing appetite, increasing anxiety, and increasing asexual desire in the animal itself. Such action provides an effective repellent effect against animals and birds. The fact that a repellent action can be obtained through such a deodorizing effect was discovered for the first time by the present inventors, and can be said to be a different concept from the concept of action of conventional repellents.

Further, a second aspect of the present invention is characterized in that a sensory stimulant that stimulates the skin, mucous membranes, etc. that sense taste, odor, pain, etc. is used in combination with the above deodorant. The action of this sensory stimulant is to change the taste, odor, etc., or to stimulate the sense of touch, taste, smell, etc. on the skin, mucous membranes, etc., so that it directly causes the animal's five senses to feel abnormalities, and physiologically. It has a repellent effect. By combining the physiological repellent effect of this sensory stimulant and the mental/psychological repellent effect of the above-mentioned deodorant, a synergistic and remarkable repellent effect can be obtained that is greater than the repellent effect exerted by each alone. Its effects remain effective over a considerable period of time. Most of the conventional repellents can be said to utilize the physiological repellent effect of stimulating the sense of taste and smell of animals, but the physiological repellent effect of sensory stimulants and the mental/psychological repellent effect of deodorants are important. By combining the effects,
It was discovered for the first time by the present inventors that the repellent efficacy is greatly improved synergistically and the duration is extended.

Most of the odor modifiers and most of the sensory stimulants are natural plant-based products and are highly safe.

The repellent of the present invention can be prepared and used in various dosage forms such as granules, powders, emulsions, and aerosols. Also,
It may be used by microcapsulating it, or by mixing it into a plastic sheet, applying it, and molding it into a bag shape.

Furthermore, it goes without saying that in addition to the above-mentioned active ingredients, diluents, fillers, retention agents, excipients, emulsifiers, etc. can be appropriately used depending on the dosage form.

〔Example〕

EXAMPLES Hereinafter, the present invention will be specifically explained with reference to Examples, but it goes without saying that the present invention is not limited to the following Examples.

Example 1 After mixing 50 g of deodorant Cineol and 50 g of Mimosa tannin, 20 g of the mixture was taken and uniformly sprayed onto 80 g of gypsum granules to obtain test granules A.

5g and 10g of the obtained test granules A were sprayed on 50g of pet food for adult cats, and 50g of untreated pet food was applied as a control to a fasted indoor cat (female, about 2 years old) at the same time. The feeding status was observed.

As a control, the feeding status of a commercially available product (particulate repellent containing limonene) was also observed in the same manner.

The test was repeated twice using the same cat in the order shown in Table 1 in order to equalize the feeding conditions, and the test was visually observed every 30 minutes, and judgment was made based on the time from when the pet food was given until the cat started eating. did.

Table 1 shows the average feeding start time of the two repeated tests.

In addition, since a certain cat usually eats around 200 g of food at one time, the dose for the above-mentioned one test was always such that the anchor would not be full.

Table 1 As shown in Table 1, when cats are placed with treated and untreated pet food, they immediately eat the untreated pet food, but do not approach the treated pet food at all and wait for the cat to eat the untreated pet food. They started eating together. For example, if a pet food No. 1 with 5g of test granule A sprinkled on it and untreated pet food are placed, the pet immediately eats the untreated pet food, but the pet that has been sprayed with 5g of test granule A immediately eats the untreated pet food. The animal did not approach the food at all and started eating after about 3 hours.

Example 2 Sensory stimulant cinnamic aldehyde 40g.

Methyl salicylate 30g 1 methylphenyl ketone 20g
After mixing 10 g of nonyl alcohol and 20 g of
was uniformly sprayed onto 80 g of gypsum granules to obtain sample granules B.

The test was conducted in the same manner as in Example 1, and the feeding status of the cats was observed. If the observation period exceeds 24 hours,
The animals were given 50 g of unprocessed bed food once a day to maintain their physical strength and to maintain a semi-starvation state. Note that observation is possible from 8 a.m. to 8 p.m.
Observations were made visually at hourly intervals (every 30 minutes until 12 hours after placement) and recorded on video from 8:00 pm to 8:00 am. The results are shown in Table-2.

Table 2 Example 3 30 g of the sample granule A and 50 g of the sample granule B were uniformly mixed to prepare a sample granule C.

Separately, 30 g of test granules A and 870 g of test granules were uniformly mixed to prepare a test granule.

The test was carried out in the same manner as in Example 2, and the observation of feeding status started from 8:00 pm and 8:00 am.
The same adult dog (male, about 2 years old) in a fasted state was given 100 g of untreated dog food and the untreated dog food as a control to observe the feeding status. As a control, the feeding status of a commercially available product (particulate repellent containing limonene) was also observed in the same manner. When the observation period exceeded 24 hours, the dogs were given untreated dog food only once a day to maintain their physical strength and to maintain a semi-starvation state.

The test was repeated twice and judged based on the time it took for the pet to start eating the food. Further, observation was performed in the same manner as in Example 3. Table 4 shows the average feeding start time of the two repeated tests.

Observations were made visually every hour from midnight to 8 p.m., and by video recording from 8 p.m. to 8 a.m. (However,
For commercially available products, observations were made every 30 minutes after the start). The results are shown in Table-3.

Table 3 As is clear from the above results, both test granules C and test granules are different from test granules A containing only a deodorant and test granules B containing only a sensory stimulant. In comparison, the repellent efficacy was significantly improved, and it was recognized that there was a synergistic effect when the deodorant and sensory stimulant were used together. It was also observed that the synergistic effect was greater in the case where a higher proportion of the sensory stimulant was used (test granules D).

2 As is clear from the above results, the product of the present invention was found to have a remarkable repellent effect against dogs. That is, when a drug treated with the repellent of the present invention and untreated dog food were placed, the dog immediately ate the untreated dog food, but did not approach the treated drug food at all, and started eating after a considerable amount of time had passed.

Example 5 There are about 15 places in a municipal garbage dump (collected twice a week) where about 10 stray cats always gather and use them as a place to live and live. There, 4 wild cats were constantly tearing open garbage bags and eating garbage. Therefore, one dose of the sample granule A was applied to the entire area.
When I sprayed 20g per dose, about 10 stray cats ran away, but about half of them came back in about an hour. Then, when 20 g of the above-mentioned sample granule per dose was sprayed in the same place, all the cats that came back ran away, and when observed every day thereafter, they did not come near at all for a week. Also, the bags of food waste that had been thrown away were not torn.

In addition, another similar municipal garbage dump (collected twice a week)
We searched for this and conducted repeated experiments.

The results are as follows.

Location A: About 10 cats live here.

When the test granules A were sprayed at a rate of 20 g/rrr, the stray cats ran away, but half of the stray cats returned one hour later. Therefore, when the test granular solution was additionally sprayed at a rate of 20 g/cat, the remaining cats ran away and did not approach for 9 days.

Location B: About 7 cats live here.

When the sample granule was sprayed at a rate of 20 g/rr, all the stray cats ran away and did not come back for a week.

Location C: About 10 cats live here.

When Test Granule B was sprayed at a rate of 20 z/cδ, the stray cats ran away, but after spraying, seven stray cats returned.

Therefore, the sample granule C was 20 g/n? After additional spraying at a rate of , all remaining cats ran away and did not approach for a week.

Location D = About 5 cats live there.

When Test Granule C was sprayed at a rate of 20 g/rrr, all the stray cats ran away and did not approach for 5 days.

The same commercial products as those used in Examples 1 to 4 were also tested in accordance with A-D above to compare their efficacy. The results are as follows.

Location E: About 10 stray cats live here.

When the commercially available product was sprayed at a rate of 20 g/rd, the stray cats ran away, but one day later, seven stray cats returned]. When the same commercially available product was sprayed again at a rate of 20 g/rrr, 7 stray cats escaped, but 2 days later, 5 more stray cats returned.

Location F: About 7 stray cats live here.

When the commercially available product was sprayed at a rate of 20 g/rrr, the stray cats ran away, but one day later, four stray cats returned.

Example 6 0.0% of each of the above test granules C and D was added to 10g of corn.
5g and 1. The pigeons sprayed with Og and 10 g of untreated corn as a control were given to the same pigeons in a fasted state, and their feeding status was observed.

In addition, for comparison, repeated tests were conducted in the same manner using the following drugs. Comparison product prescription Nijikurohexanone 80g
After mixing 20 g of green leaf alcohol, 10 g of the mixture was taken and sprayed uniformly onto 90 g of gypsum granules to obtain a comparative product (see JP-A-61-289003).

The test was repeated twice using the same pigeons, and the time taken until the pigeons started feeding was judged. Observations can be made from 8 a.m. to 8 p.m.
The test was conducted every hour until 11:00 p.m. (starting from 8:00 p.m.). In addition, since pigeons usually eat 50 g of food at one time, the dose for the above-mentioned one test is always an amount that does not leave the pigeons full. The results are shown in Table-5.

Table 5 As is clear from the above results, the product of the present invention had a sufficient repellent effect against pigeons. That is, when placing corn treated with the repellent of the present invention and untreated corn, pigeons immediately eat the untreated corn, but
They did not approach treated corn at all and began feeding after a considerable amount of time. In addition, the product of the present invention had the effect of having a considerably longer duration than the comparative product.

Example 7 A home kitchen (6
Test grains Dlog were sprinkled around rice and potatoes in two areas (a tatami room), and feeding damage was observed. In addition, as a control plot, untreated rice and potatoes were placed in the same manner and observed. Observations began at 7:00 p.m., and were recorded on video from 9:00 a.m. the next day.

As a result, the control group was eating, but the treated group was not eating at all for a week.

In addition, there was no sound of the rat coming or going, and it seemed like it had run away somewhere, confirming that the product of the present invention has a sufficient repellent effect against rats.

〔Effect of the invention〕

As described above, according to the animal and bird repellent containing the deodorant of the present invention as an active ingredient, unlike conventional repellents that stimulate the taste and smell senses of animals, the animal and bird repellent changes the atmosphere of the animal's living environment and improves mental health.・Because it has a psychological repellent effect, it has a higher repellent effect than conventional repellents against not only cats but also most animals and birds, and its duration is relatively long. can get.

In addition, according to the animal and bird repellent containing the odor modifier and the sensory stimulant of the present invention as active ingredients, in addition to the above-mentioned mental and psychological repellent effects, the sensory stimulant stimulates the animals' sense of touch, taste, smell, etc. Because it also has a physiological repellent effect,
A synergistic and significant repellent effect that is greater than the additive repellent effects obtained by each of them alone is obtained, and the effect remains effective for a considerable period of time.

Furthermore, most of the deodorants and most of the sensory stimulants used in the present invention are plant-based products that have been conventionally used as fragrances and the like, and are therefore highly safe. Therefore, concerns about the human body can be eliminated and the device can be used with peace of mind.
