Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling spiders and spiderwebs that breed on machines, furniture, automobiles, etc. in and around buildings and vehicles, benches and trees in parks and the like.

[0002]

2. Description of the Related Art There are about 30,000 spiders in the world.
Species, about 1,100 species have been recorded in Japan. The poisonous spiders that adversely affect the human body are a part of them, and only a few species inhabit Japan, but globally there are about 4 species such as the Red-faced Spider, Red-backed Spider, and Black-spotted Spider.
About 0 species are known. Although it is often bitten during agricultural work, the mortality rate of biting black widow spiders, which are highly poisonous, is said to reach about 5% when bitten. In addition, poisonous spiders may become inflamed when they are touched by human hands or skin, or may feel the pain of being stung by a needle. In addition, a hot sensation appears locally, and its range and degree expand and strengthen over time. Pain is due to ischemia associated with muscle spasticity and vasoconstriction and may be severely painful and intolerable. Physical activity can increase pain, which can lead to confusion in the patient. Spiders nest on the platforms of train stations and trains, and passengers complain, and as in the case of the red spider spider in Sakai City, spiders and poisonous spiders occur in private houses and parks, making residents uncomfortable. The people and children who were touched or touched will be damaged. Especially when it gets warm from spring to summer and autumn.

On the other hand, in order to exterminate spiders, usual insecticide aerosols and insecticides have been sprayed, but spiders are generally used between tree branches or on eaves of houses. Many of them live in hidden places, such as high places, indoor gaps, and under benches, where it is difficult for drugs to reach, and it is difficult for drugs to reach spiders due to obstacles. Spiders also live in spider webs,
Protected by a spider web. This prevents the drug from contacting the spider. Moreover, spiders, taxonomically, unlike insects, are not effective with conventional insecticides.

Regarding the susceptibility of the Red-backed Spider, a kind of poisonous spider, to insecticides, Nagata et al.
Issue, p. 135-139, 1997), there is a report of a basic indoor test. In the dry film contact test, the effects of permethrin and phenothrin are high, but it is said that if there is a nest, the effect will be greatly reduced if there are entanglements in the threads or obstacles such as dead leaves.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the problems of the prior art as described above, effectively reaches spiders in high places, and effectively reaches spiders hidden in narrow spaces. Further, the present invention provides a control agent capable of effectively controlling the recurrence of cobwebs.

[0006]

[Problems to be Solved by the Invention] The above-mentioned problem is to spray a spray-type preparation characterized in that it is filled with a pest control ingredient, a surfactant, an oily solvent, water and a spray gas to a spider or a spider habitat. The present invention has been completed by finding out that it can be solved by the above.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The active ingredients for controlling spider webs used in the present invention include phenylpyrazole insecticides, phenylpyrrole insecticides, neonicotinoid insecticides such as acetampride and nitenpyram, fenitrothion, diazinon and the like. Organic phosphorus insecticides, carbamate insecticides such as fenobucarb, carbaryl, propoxur, etc., pyrethroid insecticides such as fenpropatrine, transfluthrin, etofenprox, cifenotrin, permethrin, pralethrin, phenothrin, and neemaceae extract , Rotenone, diethyl toluamide and the like.

Examples of the spider web control agent of the present invention include M
Synergists such as GK-264, piperonyl butoxide can be added.

A surfactant can be used as the spider web controlling agent of the present invention, and a nonionic surfactant having an HLB of 3 to 8 is preferably used.

An oily solvent can be used in the spider web controlling agent of the present invention. Examples of the oily solvent include nonpolar paraffinic, isoparaffinic and kerosene organic solvents. The oily solvent used in the present invention preferably has 12 to 16 carbon atoms. Commercially available products include, but are not limited to, isoper, neothiozole, and shell sol. Also, a deodorized solvent is suitable.

Water can be used as the spider web control agent of the present invention, and deionized water, distilled water and the like from which impurities have been removed are preferably used. Alternatively, a buffer solution may be used.

As the propellant gas used in the spider web control agent of the present invention, liquefied propane gas, propane gas, butane gas, isobutane gas, or a mixture of two or more thereof is used. If necessary, dimethyl ether, nitrogen gas, air or the like may be added to these mixtures.

The present invention is described below with reference to examples, but the present invention is not limited to the examples.

[0014]

[Formulation Example 1]                                 (G / 100g of formulation)           Fenpropatorin 0.2           Surfactant 0.5           Isopar 8.0           Deionized water 56.3           Liquefied propane gas 35.0

[0015]

[Example 1] A spider occurred in a train in a train station at a JR station in Kansai in the summer, and passengers complained of discomfort and uncleanness to the spider web. The spider web control formulation obtained in Formulation Example 1 was used for 3 vehicles.
Approximately 170 mL per vehicle (20
˜30 mL / m 2) was sprayed, and the generation status of cobwebs was compared with the untreated control group 3 vehicle. The test period was from the beginning of July to the end of August. The test results are shown in Table 1.

[0016]

[Table 1]

[0017]

[Formulation Example 2]                                     (G / 100g of formulation)             Transfluthrin 0.4             Surfactant 1.0             Isopar 10.5             Deionized water 50.0             Liquefied propane gas 38.1

[0018]

[Example 2] It is said that a red-backed spider, a kind of poisonous spider, lives under and around a bench in a park in Sakai City, Osaka Prefecture, which may cause harm to children who come to the park for play. The control measures were examined. About 5 benches, about 10 benches of the spider web control preparation obtained in Formulation Example 2 were used around the habitat of the red hemlock spider.
mL was sprayed, and the habitation status of the red hemlock spider and the occurrence status of a spider web were compared with 5 benches of the untreated control group. The test period was from the beginning of August to the end of September. The test results are shown in Table 2.
