Examples of the deodorant include lauric acid methacrylate, and examples of the aromatic include essential oil components of rush, citronella, lemon, lemongrass, orange, eucalyptus, lavender and the like. If necessary, various additives such as a potency enhancer and a desiccant (superabsorbent resin) may be added to the tick agent for controlling ticks used in the present invention. The tick agent for controlling mites used in the present invention has, for example, at least one injection hole having a shape capable of being pierced into a tatami mat on at least a part of the peripheral surface of the body of the tubular body. The tubular body having the above-mentioned configuration is used by being filled in a tatami mating tool having a tip end of the tubular body having a substantially blind shape and having a nozzle opening diameter of 0.1 to 1.0 mm. The shape of the tubular body (hereinafter referred to as the main body) is such that the front end portion is substantially blind and the front end portion of the main body can be easily pierced into the tatami mat from any of the front, back and side surfaces. As long as it has a shape, it is not limited in length or size (width), but the length is preferably 4.3 to 4.7 cm according to the tatami standard (thickness 5 cm), and the thickness is tatami at the time of pricking. It can be used as long as it does not leave a puncture on it, and the inner diameter of the main body is preferably 1.5 mm or less from the viewpoint of usability. Further, the main body may have a form such as expandable, bendable (including one having a rubber tube in the middle), detachable, removable, axially rotatable, and the like, or a plurality thereof. But it's okay. As the material, a material suitable for these forms can be appropriately selected and used. By making it rotatable as described above, the position of the injection hole can be appropriately changed and used, so that even if there is only one injection hole, spraying over a wide range is advantageous. Further, a fitting portion for the push button may be provided at the base end of the main body. By doing so, for example, when using an aerosol,
Although it is advantageous that the setting can be easily performed by simply fitting the push button on the existing push button or the nozzle, the push button may be provided on the base end of the main body as well. The area of the injection hole provided in the main body may be the same as or smaller than the inner diameter of the main body, and the diameter of the injection port is usually in the range of 0.1 to 1.0 mm, preferably 0.3 to 0.6.
mm, and when the fitting portion or the push button is provided as described above, it is advantageous that the sprayed state becomes good if the relationship of the injection hole diameter of the push button ≧ the inner diameter of the main body ≧ the injection hole diameter of the main body is satisfied. However, if more uniformization is required in the weakly sprayed state, it is not particularly affected by this. The number of injection holes of the nozzle is determined from the above-mentioned relationship. The nozzle hole may have a normal shape or a slit shape. In this case, it may have a vertically long shape or a horizontally long shape (including a ring shape).
It is advantageous for jetting into each layer constituting the tatami mat, and is suitable for wide-area planar treatment in the eight directions of the tatami mat if it is horizontally long. By using these in combination, a more preferable spray state can be obtained. In addition, it is advantageous that the combined type has a cross-shaped shape on the front surface because the advantages of both can be obtained at the same time. The injection holes may be provided in the main body by providing at least one or more in at least one part of the outer peripheral surface of the body of the main body, and may be provided at appropriate intervals in the longitudinal direction of the main body. Of course, in this case, it is advantageous that each layer constituting the tatami mat can be treated at once as in the case of the vertically elongated slit-shaped injection holes. Further, the injection holes may be provided at positions corresponding to the layers forming the tatami mat so that the processing can be performed with one touch. At this time, it is advantageous that the injection holes are provided in a staggered manner because a wider range of processing can be performed. In the present invention, as the injection mechanism applied to the main body, any injection mechanism used for this kind of application can be used, for example, an aerosol type, a type utilizing various pumps, a type using a cylinder. ,compressor-
It can be used in appropriate combination with the above.
When the cylinder is used, the pressure is considerably high, and therefore it is used by attaching it to an appropriate spray gun. Other appropriate auxiliary means may be adopted for the main body, and for example, from the viewpoint of safety when the tip of the main body is not used, it can be attached and detached at an appropriate position in the longitudinal direction of the main body (of course, the base end part may be used). As an alternative, it can be replaced vertically or horizontally, or a stopper that can be slid vertically or horizontally is provided on the body of the main body, which is used to adjust the degree of entry of the main body into the tatami mat when in use, and when not in use The stopper can be protected by shifting the stopper toward the tip of the body, stopping when the tip is no longer visible, and fixing the body to the body with a set screw, etc. 4). Further, the tubular body can be used by accommodating the main body into and out of the container so that the tubular body can be used by retracting a part of the container. When not in use, the main body is accommodated in the container. However, it is safe to provide a proper stopper to the container just in case. Further, instead of being housed in the container, the main body itself may be used in combination with, for example, a bellows cover and a stopper for preventing the cover from being reduced. In the present invention, the atomizer as one of the above-mentioned atomizing mechanism may be an automatic injection type with an intermittent valve. In this case, if the main body provided in the sprayer is set toward the place where cockroaches appear and disappear, such as the gap on the back side of the tatami mat, the aerosol is automatically and automatically applied to such places where cockroaches appear and disappear. It can be jetted intermittently. In the present invention, the hole diameters of the main body nozzle, push button nozzle and valve stem are in the range of 0.3 to 0.6 mm, and the hole diameter and vapor of the injection valve housing are set.
The hole diameter of the tap is in the range of 0.3 to 0.5 mm, and the difference between the hole diameter of at least one selected from the injection valve housing and dip tube and the hole diameter of the vapor tap is 0.1 mm. It can be configured to be within. In this case, it is possible to advantageously use, as the filling liquid, one in which the active ingredient solution is 30 to 60% by volume when the active ingredient solution and the propellant are combined. In the case of an aerosol agent which is normally used upright, the hole diameter of this housing is 0.7 to 1.5 mm, and the hole diameter of the dip tube is 1 to 3.5 mm, which is large.
The hole diameter of the tap is about 0.25 to 0.4 mm, and the difference is
This is much larger than 0.1 mm, and if this is used upside down, a large amount of propellant will be sprayed, and the ratio with the active ingredient solution in the aerosol can collapses.
By setting the distance to 0.1 mm or less, for example, if the insecticide is used, the potency will be even, and the propellant will not go out first and only the active ingredient solution will not remain without being ejected. There is an advantage that the injection amount can be made almost the same. The active ingredient solution referred to in the present invention means a solvent whose vapor pressure is substantially lower than the injection pressure at room temperature, such as hexane, 3,3,4-trimethylnonane, cyclohexane, kerosene, Petroleum solvent such as naphtha, normal paraffin, isoparaffin, liquid paraffin,
Chlorinated hydrocarbons such as dichloroethane and trichloroethane, alcohols such as ethyl alcohol, isopropyl alcohol and ethylene glycol, and ether derivatives, and solvents such as water such as allethrin, permethrin and phenothrin. , At least one of them, an organophosphorus insecticide such as DDVP and fenitrothion, a synergist such as a carbamate insecticide and piperonyl butoxide, and a deodorant or deodorant are dissolved as they are or a surfactant. Is emulsified in. As the propellant, for example, CFCs (CFC-11, CFC-112, CFC-113, etc.), liquefied petroleum gas, dimethyl ether, etc. may be used alone or in combination. Next, an example of the formulation of the mite controlling aerosol agent used in the present invention will be explained. Formulation Example 1 0.3 parts by weight of at least one of phenothrin, permethrin and resmethrin, 7 parts by weight of xylol, deodorized kerosene
7.7 parts by weight were mixed and dissolved. This was filled in an aerosol container, the valve portion was attached, the valve portion was sealed, and 85 parts by weight of liquefied petroleum gas was pressure-filled to obtain an aerosol of a tick controlling agent. Next, the method for controlling ticks of the present invention will be described in more detail based on examples, but the present invention is not limited to these examples. Examples 1 to 6 150 ml of a kerosene solution containing 1.33% of permethrin, a pyrethroid compound, and 150 ml of liquefied petroleum gas were filled in an aerosol can with an internal volume of 390 ml and sealed with a valve as shown in Table 1. , I got an aerosol agent. A button is attached to this, the main body is connected, and an injection test (30 seconds each) is performed, and the difference between upright and inverted is 10% or less, and 20% or less is acceptable. The results are also shown in Table 1. [Table 1] Examples 7 to 10 In the same manner as in Example 1, except that the propellant used was 70 ml of dimethyl ether and 80 ml of liquefied petroleum gas, an aerosol agent was obtained. The physical properties of the obtained aerosol agent are shown in Table 2. [Table 2] Next, a tatami mating tool that can be preferably used in the method for controlling ticks of the present invention will be described. FIG. 1 is a partially cutaway front view showing an example of a tatami mat treatment tool used in the tick control method of the present invention, FIGS. 2 and 3 are sectional views showing another example, and FIG. 4 is still another example. It is a partially cutaway front view showing. In FIGS. 1 to 4, reference numeral 1 is a main body, and a plurality of injection holes 2 are provided on the peripheral surface of the main body 1, and the tip of the main body 1 has a shape capable of being pierced into a tatami mat. There is. At the time of use, by connecting it to a suitable spraying means such as an aerosol or cylinder, and inserting it into the tatami room and injecting it, the drug can be sprayed from the nozzle hole of the nozzle as shown in the test results below. A sprayed state can be obtained and a very good diffusion distribution state can be obtained in the tatami mat. In addition, the insecticidal effect was also very good, and it has a characteristic structure as an insecticidal tool for tatami mats. In such a tatami mat treatment tool, when the injection hole is provided and the shape is divided into a plurality of stages (FIG. 1).
Up to 4). Next, the main body 1 may be provided with a push button of a sprayer or a fitting portion for fitting with a spray cylinder (which is advantageous because it can be directly attached to the push button or the like) at the base end of the main body 1 (see FIG. 1). ), Or a push button may be provided (see FIGS. 2 and 3). In this case, in FIG. 2, the upper surface 4a of the push button 4 serves as the pressing surface when the main body 1 is inserted into the tatami mat when it is attached to the stem of an ordinary sprayer, so that the surface of the tatami mat can also be used as the pressed surface. Since it is possible, it is easy to use, and the one shown in FIG. 3 is advantageous when the sprayer is laid sideways. The tatami mat processing tool shown in FIG.
A tubular cover 5 is slidably provided on the body of the body, and a screw 5b having a length reaching the peripheral surface 1a of the main body 1 is provided in the middle of the peripheral surface 5a of the cover 5, and the cover 5 is provided at an appropriate position. 5 is configured to be stopped. In this case, by screwing the screw 5b where the tip of the main body 1 is hidden from the lower end of the tubular cover 5, the tip of the main body 1 can be protected and the danger from the use can be eliminated, and the body can be slid freely. It is advantageous because the depth (the degree of penetration (insertion) of the nozzle into the tatami mat) can be adjusted. The diffusion test and insecticidal efficacy test using the above tatami mat treatment tool will be described below.
