Description

Detailed Description of the Invention

[0001] [Detailed Description of the Invention]

TECHNICAL FIELD The present invention relates to the control of termites,
In particular, the present invention relates to a device (station) used in a so-called bait construction method, in which termite colonies (nests) themselves are completely destroyed by attracting termites with bait and feeding poison baits.

[0002]

2. Description of the Related Art As a method for exterminating termites that have a fatal effect on houses and other structures and trees, soil treatment and xylem treatment using a chemical solution have been mainly performed on-site. . However, many of the chemicals used are harmful to the human body and there is a problem in safety during processing.

Therefore, recently, from the viewpoint of environmental measures, safety measures, and efficiency improvement, wood factory treatment, sheet construction method, bait construction method, etc. are becoming popular. In particular, the bait method using a bait agent (poison bait) started in the United States and has been practiced in Japan 4 to 5 years ago, and is a safe and clean method, and is attracting attention as an efficient exterminating method.

In this bait method, termites are eradicated before they enter a house or the like. For example, a termite-preferred lumber container is buried in the ground outside the house to attract termites. When it is found that termites are eating this bait tree, part of the bait tree is replaced with poison bait. The bait contains a delayed insecticidal component, but the non-toxic portion of the substrate is made by what termites prefer, so termites will carry this bait little by little to colonies, resulting in It leads to the annihilation of termites in the colony.

The bait station, which is used in the bait construction method and is buried in the ground, is a cylindrical shape because it is inserted and installed by opening a hole (depth 20 to 30 cm) in the ground with a drill (auger). Has been formed.

However, the cylindrical station
Not only is the area small in the direction of movement of the ant path, but the bait trees are inserted so as to be densely packed, so it will disturb the termites when exchanging with poison bait, and depending on the type of termites such as Yamato termites, it will never again be at that station. May occur even if it does not come near.

[0007]

SUMMARY OF THE INVENTION The present invention has the same volume as a cylindrical station, has a large area in the direction of the ant path of termites, has a high trapping efficiency, and is sensitive to sensitive termites with minimal stimulation. We propose a termite control device that is a station that can be replaced with.

[Means for Solving the Problems] That is, according to the present invention, there is provided a case body which is embedded in the ground of a bookcase type which has an upper surface opened and front, rear, left and right surfaces and a bottom surface are in a knitted shape.
It consists of a detachable lid plate that covers the upper opening of the case body. Inside the case body, multiple bait trees are placed in a horizontal row during monitoring, and when a termite is found, 1 bait tree is placed.
Alternatively, the present invention relates to a termite control device in which a plurality of trees are replaced with a poison tree containing a delayed insecticidal poison.

The case body is made of synthetic resin and the lid plate is made of stainless steel. To prevent the case body from sinking when it is buried in the ground, the case body is provided outside the upper and left upper ends of the case body. It is preferable to form a projecting shoulder portion that projects obliquely downward along the thickness direction. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0010]

FIG. 1 is a perspective view of the entire instrument of the present invention,
FIG. 2 shows a state in which this device is buried in the ground around a house, 1 is a synthetic resin case main body, 2 is a case main body 1
Is a lid plate made of stainless steel that covers the upper opening of the case body 1, and the height of the case body 1 is almost the same as the conventional one (height:
15-20 cm), the width is long (width: 22-30 cm),
The thickness of the front and back is thin (thickness: 2 to 5 cm), and it is a flat bottomed rectangular bookcase type.

The front, rear, left and right, and bottom surfaces of the book case type case body 1 are made of a mesh-like transparent material so that termites can enter and exit, and at least front and rear surfaces are provided with reinforcing ribs 3 up and down. -It is provided in the left-right direction or the diagonal direction.

Reference numeral 4 denotes projecting shoulders formed at both upper left and right upper ends of the case body 1 so as to project obliquely downward along the thickness direction of the body 1, and the projecting shoulders 4 and 4 when buried in the ground. Prevent the case body 1 from sinking.

Reference numeral 5 denotes a plurality of square rod-shaped bait trees which are inserted into the case body 1 from above. For example, pine wood or sawdust hardened, which contains cellulose preferred by termites, is used in the case body 1. A size that can be loosely inserted in a horizontal row (for example, width 2-5 cm, thickness 1.5-4 cm, height 13-18)
cm), and the figure shows an example of inserting four bait trees 5 of the same size in a horizontal row, but a larger number of bait trees 5 can be inserted in a horizontal row by arbitrarily changing the width. You may do it. At the head end of each bait tree 5, a knob 6 for grasping with a finger at the time of insertion into and removal from the case body 1 is driven and fixed.

7 is a square rod-shaped poison tree (bait) having the same height and thickness as the bait tree 5. The poison tree 7 is made by solidifying wood of the same quality as the bait tree 5 or sawdust and other cellulosic material into a rectangular parallelepiped. Slow-acting insecticidal (kills after several days or weeks) poisons, such as hexafromuron,
An impregnated or coated solution prepared by using chlorfluazuron, sulfamide, hydramethylnon or the like is used. In the figure, the poison tree 7 has a width half that of the bait tree 5, but it may be wider or narrower than that, and when one or more bait trees 5 are removed from the case body, the removal thereof is eliminated. It is necessary to prepare a plurality of pieces so that they can be arranged in one row in the width direction of the case body 1 relatively densely in the gap. The knob 6 is fixed to the head end of the poison tree 7 in the same manner as described above.

The elongated cover plate 2 made of stainless steel is slightly larger than the upper opening of the case body 1, and two parallel guide plates 8, 8 fitted to the outer surfaces of the front and rear upper edges of the case body 1 project from the lower surface thereof. A screw insertion hole 9 is provided in the central portion of the lid plate 2, and the screw hole is provided on the upper surface of the spacer 10 which is fixed by passing the hole 9 between the central portions of the front and rear upper edges of the case body 1. The cover plate 2 can be fixed on the case body 1 by screws 12 in conformity with 11.

Therefore, this termite controlling device is used as follows. First, for example, in the surrounding ground of the building 13 that is a target for preventing termite intrusion, elongated grooves that are slightly larger than the case main body 1 are dug at intervals of 3 to 5 m with angular shovels, and the upper edges of the case main body 1 are approximately the same height as the ground in the grooves. The lid plate 2 is screwed and fixed so that the cover plate 2 is inserted and installed so as to be in the position (see FIG. 2). At this time, only one bait tree 5 is filled in one horizontal row (four bait trees in FIG. 1) in the case body 1. This will monitor the presence of termites.

If wood pieces such as plates are inserted and installed on both front and rear sides of the case body 1 set in the ground so as to be in contact with both sides of the body, the front and rear sides of the case body 1 are closed. Is retained, and a further attractive effect on the termites (due to water and wood) can be expected.

Therefore, when monitoring is performed once a month and termites are found in the case main body 1, at least one bait tree 5 in the main body 1 is detected depending on the activity status of the termites.
Take out and replace with poison tree 7. In this case, the bait tree in which the most termites are active is not replaced, but the bait tree with the least termites farthest away is replaced with the poison tree. When the poison tree 7 is half the width of the bait tree 5, it is replaced with two poison trees.

Then, the monitoring is continued, and when the food condition of the bait tree 5 is not deteriorated, the bait tree is replaced with the poison tree 7, but the bait tree which causes the most ant damage is left and the case body 1 Stimulate the termites inside so as not to disturb or break the passage. Also, when the poison tree 7 becomes less than half, it is replaced with a new poison tree 7.

In this way, the consumption of the poisonous tree 7 and the bait tree 5 by the termites gradually decreases, the termite activity is not recognized, and the termite extermination is completed after a predetermined period (for example, 2-3 months) has elapsed. Of.

[0021]

The termite control device of the present invention is constructed as described above, and the case body is formed into a transparent oblong flat shape that allows the termites to move in and out, for example, a conventional cylindrical station having a diameter of 10 cm. The area of a plane equivalent to that of (about 75 cm ² ), but with a thickness of 3 cm, the book type device of the present invention can extend the barrier surface up to a width of 25 cm with respect to the building to be protected. In addition to securing a wider catching area than the conventional cylindrical type of capacity, if there are dense termites on one side of multiple bait trees, the farthest bait tree on the other side should be used. By exchanging with poisonous trees, even particularly sensitive termites such as Yamato termites can be replaced with poisonous bait with minimal stimulation, so there is no worry of disturbing or breaking the ant trail.

Further, since the case body is a horizontally long and flat book case type, it is possible to easily avoid underground piping and wiring when burying the case body around a building, as compared with a cylindrical type case. Since the main body has a rectangular shape and can be compactly packaged, it has advantages such as being convenient for transportation and transportation.
