Description

  The present invention relates to a white ant extermination device that damages a white ant's nest by feeding a white ant impregnated with a chemical (poison bait) to protect the white ant's nest from damage.

  Conventionally, as a technique for preventing buildings from being damaged by white ants, a chemical (chemical solution) having an insecticidal or repellent effect is sprayed and adsorbed on the soil, for example, under the floor of the building, and the soil on which this chemical is adsorbed (white ants cannot penetrate). A method for preventing white ants from entering the building by a possible barrier) is generally implemented. Moreover, the effect duration of the chemicals used in these soil treatments and the guarantee period accompanying the treatment are usually 5 years, and it is necessary to carry out the chemical treatment again after the duration of the effect maintenance period of the chemicals.

  However, depending on the structure and foundation shape of the building, it is often impossible to perform appropriate chemical treatment on the necessary parts at the necessary time after the new construction, and it is also possible to work under the floor. However, it is obvious that it is not preferable for the operator to perform chemical treatment such as spraying in a narrow and semi-closed space such as under the floor. In addition, such chemical spraying under the floor in residence may be a problem for residents due to concerns about the deterioration of indoor air quality and the impact on the living space under the social trend of the development of laws concerning indoor air quality. It also becomes an anxiety factor.

On the other hand, there is a technique that is performed as a method for preventing and extinguishing white ants instead of the conventional method for treating chemicals under a building (for example, see Patent Document 1). In the technique described in Patent Document 1, as shown in FIGS. 7 and 8, a case 101 is embedded in the soil so as to surround the periphery of the building 100. Then, a bait tree 102 is placed in the case 101, white ants are attracted to the case 101 buried in the soil, and after confirming the damage of the white ants, the bait tree 102 is impregnated with a slow-acting drug. It replaces with a tree (not shown) and causes white ants to be harmed. This bait tree is brought back to the white ant's nest, and the whole nest is damaged by the exchange between white ants in the nest.
JP 2003-137705 A (paragraph 0004)

  By the way, the white ant extermination device disclosed in Patent Document 1 attracts white ants to the case 101 embedded in the ground with a bait 102 inside. However, when a white ant travels in the ground, it does not recognize the feeding tree 102 from a distance or digs for the feeding tree 102. The white ant travels in the ground at random as indicated by the arrow a shown in FIG. In this way, the “case” of the case 101 is encountered and proceeds in the direction of the arrow b in FIG. As a result, the presence of the “feeding tree 102” is transmitted to the nest, the route between the nest and the case 101 is strengthened, and the harm is promoted.

  Therefore, the expected value of the preventive result for the white ants by such a white ant extermination device depends on the possibility of “incidentally encountering”, and does not encounter the case 101 buried in the soil, and the arrow in FIG. If the white ants progress as in c, it is easily expected that the original purpose of harming the building to be prevented will proceed. Therefore, in order to increase the possibility of encountering the case 101, that is, the reliability as a preventive technique, the installation interval of the case 101 buried in the soil is narrowed as shown by a case 101 'indicated by a dotted line in FIG. Many cases 101 'need to be installed, but it is very expensive, and the upper parts of cases 101 and 101' need to be exposed to the ground surface for inspection. There is a problem that there are many cases where it is impossible to install due to the construction of the outer groove of the door, and there are many cases where the appearance is not preferable depending on the installation position of the entrance. Furthermore, the installed case 101 needs to be periodically inspected for the damage of the bait tree 102 by white ants at a frequency of about twice a year, and when the number of cases 101 becomes enormous, the inspection itself is required. There is a problem that time and burden increase and maintenance costs increase.

  In view of the above problems, the present invention provides a white ant extermination device for protecting a building from white ants safely and for a long period of time by using an appropriate amount of medicine at a necessary time during the aging of the building. Objective. In addition, another object of the present invention is to provide a function for guiding white ants to feeding trees, to improve the reliability of white ants as a technology for preventing white ants, to improve aesthetics, and to maintain maintenance costs. It is an object of the present invention to provide a white ant extermination device that can reduce the amount of ant.

  In view of the above-mentioned problems, the present inventors have completed the present invention on the basis of a behavior such that white ants enter the building from the foundation of the building and travel along the foundation surface of the concrete.

The present invention is configured to solve the above-mentioned problems, and the invention according to claim 1 includes a plurality of trap outer cases embedded in soil around a building and containing bait for white ants. A plurality of white ant guide plates embedded in the soil and arranged between the trap outer cases to contact the trap outer case to guide the white ants toward the trap outer case , The white ant extermination device, wherein the outer case and the plurality of white ant guide plates are arranged so as to surround the periphery of the building .

  According to the first aspect of the present invention, when a white ant traveling in the soil encounters the white ant guide plate, it proceeds through the soil while connecting the surface of the white ant guide plate due to the behavior. Since the white ant guide plate extends toward the trap outer case, the white ant is guided to the trap outer case through the white ant guide plate, and harms the bait in the trap outer case. The white ants that have harmed the bait will return to the nest and tell the other white ants that there is food, and as a result, the route between the white ant's nest and the trap outer case will be strengthened, and the damage of food by many white ants will progress To do. Then, after confirming the harm of the bait in the trap outer case, the bait can be brought home by replacing the bait with bait treated with a poison, for example, and the nest can be damaged. Therefore, it is not necessary to reduce the installation interval of the trap outer case in order to introduce the white ants into the trap outer case as in Patent Document 1, and the number of trap outer cases can be reduced and the cost can be reduced. In addition, in the case of Patent Document 1, when the number of trap outer cases is increased, it is necessary to check whether or not white ants are damaging bait for all trap outer cases, and the time and burden required for the inspection itself are large. Become. However, according to the present invention, since the number of trap outer cases can be reduced by using the white ant guide plate, it is not necessary to perform the inspection work of a large number of trap outer cases as described above. Workability can be improved.

Invention according to claim 2, bait for the termites to be accommodated in the trap exterior case, and food subjected to poison process, and a bait termites provided to cover the outer surface of the bait prefer It is comprised so that it may be included, It is a pea extermination apparatus of Claim 1 characterized by the above-mentioned .

  According to the second aspect of the present invention, since the bait preferred by the white ants is provided so as to cover the outer surface of the bait that has been subjected to the poisoning treatment, the white ants traveling in the soil encounter the trap outer case and the trap outer case. When entering, the white ants first damage the bait preferred by the white ants. As a result, the route between the white ant's nest and the trap outer case is strengthened, and the bait injuring by many white ants advances. When the bait is injured, the poisoned bait is exposed to the outside, the white ants harm the bait that has been poisoned, bring the bait back to the nest, and damage the nest. Therefore, like the patent document 1, after confirming the damage of the bait by the white ants, the exchanging operation of exchanging the bait with bait impregnated with a slow-acting drug can be omitted.

  ADVANTAGE OF THE INVENTION According to this invention, a white ant is induced to a bait using a white ant guidance board, and the reliability as a white ant prevention technique with respect to a building can be improved. Further, it is not necessary to increase the number of trap exterior cases embedded in the ground as in Patent Document 1 to reduce the interval between the cases, so that the aesthetics can be improved and the maintenance cost is reduced. can do. Moreover, since the number of trap outer cases can be reduced as described above, the effect can be exerted with a small amount of chemicals, and the building can be protected from the damage of white ants for a long period of time. Furthermore, as in Patent Document 1, after confirming the damage of the bait by the white ants, it is possible to omit the exchange work of exchanging the bait with bait impregnated with a slow-acting drug, thereby reducing maintenance costs. can do.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the description, the same reference numerals are used for the same elements, and redundant descriptions are omitted.

  FIG. 1 is a perspective view showing a white ant extermination device according to an embodiment of the present invention, and FIG. 2 is a plan view of FIG. 3 is an enlarged cross-sectional view of the trap outer case, bait tree, and white ant guide plate as seen from the direction of arrows III-III in FIG. FIG. 4 is a cross-sectional view of the trap outer case, bait tree, and white ant guide plate as seen from the direction of arrows IV-IV in FIG. 3.

  As shown in FIG. 1, the white ant extermination device 1 according to the present embodiment is installed so as to surround a building 2. And the white ant extermination device 1 is constructed such that the four trap exterior cases 3, 3,... Buried in the ground at the four corners of the building 2 and the trap exterior cases 3, 3 are connected to each other. Of the long white ant guide plates 4 and 4 (hereinafter referred to as white ant guide plates 4 and 4) embedded in the ground and extending in parallel with each other along the longitudinal direction of each of the trap exterior cases 3 and 3 Short peanut guide plates 5 and 5 (hereinafter referred to as peacock guide plates 5 and 5), which are embedded in the ground and extend parallel to each other in a direction orthogonal to the pea guide plates 4 and 4 so as to connect each other. It has. The white ant guide plates 4 and 4 and the white ant guide plates 5 and 5 are arranged so as to surround the building 2 in a rectangular shape.

  Here, when a white ant that travels in the ground in the direction of arrow A in FIG. 2 toward the building 2 hits the white ant guide plates 4, 4, 5, 5, the white ant is turned into the white ant guide plates 4, 4, 5, 5. 5 has a habit of traveling in the direction of arrow D or arrow D ′ in FIG.

  The white ant guide plates 4, 4, 5, and 5 have long-term durability in the ground and are preferably not damaged by white ants, such as metal plates and concrete plates. Those with the chemical treatment are not suitable for use because they avoid white ants. Further, the deeper the lower ends of the white ant guiding plates 4, 4, 5, and 5, the higher the probability of guiding the white ants. However, since the white ants do not like moist soil, it is preferable to set the lower ends of the white ant guide plates 4, 4, 5, and 5 according to site conditions such as the water level. Further, in order to prevent the white ants from climbing over the white ant guide plate 4 in the direction of arrow C in FIG. 2, for example, the upper ends of the white ant guide plates 4, 4, 5, and 5 are on the ground surface G (see FIG. 3). The closer it is possible, the better.

  The trap outer case 3 is formed as a cylindrical body extending in the vertical direction. The trap outer case 3 is integrally provided at the lower end of the cylindrical portion 3B and the cylindrical portion 3B which is a peripheral surface in which a large number of holes 3A, 3A,... Similarly, it consists of a bottom 3D, which is a bottom surface in which a large number of holes 3C through which white ants can enter and exit, and a disc provided on the upper end of the cylindrical portion 3B so as to be opened and closed via a hinge (not shown). And an upper lid 3E. The trap outer case 3 preferably has long-term durability in the ground and is not subjected to chemical treatment such as indestructible treatment. Those subjected to chemical treatment such as anti-corrosion treatment are not suitable for use because they avoid white ants. And the cylindrical part 3B of each trap exterior case 3 is arrange | positioned so that it may contact the surface of the edge part side of both white ant guidance plates 4 and 5, as shown in FIG.1 and FIG.4. Therefore, the white ants that have connected the surface of the white ant guide plates 4 and 5 in the directions indicated by arrows D and D 'in FIGS. 2 to 4 are cylindrical in the direction indicated by the arrow E (see FIGS. 3 and 4). It is guided to bait 10 for white ants accommodated inside the trap outer case 3 through the hole 3A of 3B. Also, white ants can be guided to the inside of the trap outer case 3 through the holes 3C of the bottom 3D. The hole 3C of the bottom 3D also has a function as a hole for draining water.

  As shown in FIG. 3 and FIG. 4, the white ant bait 10 covers, for example, a square pillar-shaped bait tree 10 </ b> A that has been treated with a poison that is a slow-acting drug, and an outer surface of the bait tree 10 </ b> A. It is composed of a square tube-shaped bait tree 10B made of a material preferred by the white ants provided. In addition, it is preferable to form the feeding tree 10A and the feeding tree 10B using a pine or the like preferred by white ants.

Next, the effect of the white ant extermination device 1 configured as described above will be described.
First, when a white ant that travels toward the building 2 in the direction of arrow A in FIG. 2 hits the white ant guide plates 4, 4, 5, and 5, the white ant guides the white ant guide plates 4, 4 due to its behavior. , 5 and 5, and proceed in the direction of arrow D or the direction of arrow D ′ in FIGS.

  Here, in this Embodiment, the cylindrical part 3B of each trap exterior case 3 is arrange | positioned so that the surface by the side of the edge part of both white ants guidance plates 4 and 5 may be contacted. For this reason, the white ants that have traveled through the surface of the white ant guiding plates 4, 4, 5, and 5 to the end side of the white ant guiding plates 4, 4, 5, and 5 are directed in the direction of arrow E in FIGS. And enters the case 3 through the hole 3A of the trap outer case 3, and harms the bait 10B. In addition, even when a white ant that is traveling in the ground happens to encounter the trap outer case 3, it enters the trap outer case 3 in the direction of arrow F in FIGS. 3 and 4 and harms the bait 10B. . Then, the white ants that have harmed the bait tree 10B return to the nest and inform the other white ants of the location of the white ant bait 10. As a result, a plurality of white ants enter the trap outer case 3, the route between the white ant nest and the trap outer case 3 gradually expands, and the plurality of white ants harm the feeding tree 10B through the route. In this way, the feeding tree 10A is gradually exposed to the outside as the feeding tree 10B is injured. As a result, the white ants bring the feeding tree 10A back to the nest together with the feeding tree 10B, and between the white ants in the nest. The white ant nest is damaged by the exchange of the feeding tree 10A, and finally the entire nest is eradicated.

  Therefore, according to the present embodiment, white ants are guided to the white ant bait 10 using the white ant guide plates 4, 4, 5, 5, and the reliability of the white ants as a technology for preventing white ants can be improved. Moreover, it is not necessary to prepare a large number of trap outer cases buried in the ground as in Patent Document 1, and the interval between the trap outer cases 3 can be widened. As a result, the number of the trap outer cases 3 can be reduced as compared with that of Patent Document 1, so that the aesthetics can be improved and the maintenance cost can be reduced. In addition, since the bait preferred by white ants is provided so as to cover the outer surface of the bait that has been subjected to poisoning treatment, as shown in Patent Document 1, this bait is impregnated with a slow-acting drug after confirming the damage of the bait by the white ants. An exchange operation for exchanging with the fed bait can be omitted, and this can also reduce the maintenance cost. Furthermore, since the number of the trap outer cases 3 can be reduced as described above, the effect can be exerted with a small amount of medicine, the building can be protected from white ant damage for a long time, and it is safe for the resident and for a long time. You can protect the building from white ants.

  In the present embodiment, the case where the trap outer case 3 is configured to contact the surface of the white ant guide plates 4, 4, 5, and 5 has been described as an example. However, the present invention is not limited to this. For example, as in the first modification shown in FIG. 5, a notch recess having substantially the same width and groove depth as the diameter of the trap outer case 3 is provided on the white ant guide plate 4 ′. A groove 4A ′ may be formed, and the trap outer case 3 may be fitted into the cutout recessed groove 4A ′ as indicated by an arrow.

  Moreover, in this Embodiment, although the case where the bait 10 for white ants was formed in prismatic shape was mentioned as an example, this invention is not restricted to this, For example, like the 2nd modification shown in FIG. In addition, a white ant bait 10 'comprising a bait tree 10A' and a bait tree 10B 'covering the outer surface of the bait tree 10A' may be formed in a spherical shape.

  Furthermore, in the present embodiment, the case where a plurality of holes 3A for allowing white ants to enter and exit the trap outer case 3 is described as an example, but the present invention is not limited to this, and the trap outer case 3 is not limited thereto. The cylindrical portion 3B and the bottom portion 3D may have a mesh structure.

  Furthermore, in this Embodiment, the white ant extermination apparatus 1 is comprised including both the white ant guide plates 4, 4, 5, and 5 and the double structure white ant bait 10 composed of the feeding trees 10A and 10B. Although the present invention has been described by way of example, the present invention is not limited to this. For example, white ant guide plates 4, 4, 5, and 5 are used, and the double pea bait 10 is abolished. A white ant bait made of one material may be used, or a white ant bait 10 having a double structure may be used, and the white ant guiding plates 4, 4, 5, 5 may be omitted.
