Description of the Related Art Conventionally, for the control of mites, organic substances such as organic phosphoric acid, pyrethroid type substances, carbamate type substances, diazinon type substances, orthoboric acid, sodium borate, sodium octaborate tetrahydrate, etc. Inorganic boron compounds are used. It is also known to incorporate these substances into a sheet, for example, as disclosed in JP-A-63-130509. However, since the above-mentioned organic substance having a tick-proofing effect is highly toxic, there is a concern that it may affect the human body when used in a large amount. On the other hand, the inorganic boron compound has no problem of toxicity, but has a problem that the drug effect is lost in a short period of time because it is water-soluble.

-RO based, there is a B 2 O 3 -Na 2 O- Al 2 O 3 system. Where RO
Means an oxide of an alkaline earth metal such as CaO or MgO. These vitreous substances elute B 2 O 3 which is effective for controlling ticks under hot and humid conditions where mites tend to reproduce, but B 2 O 3 is not so much under low temperature drying conditions which are not suitable for tick reproduction. Since it does not elute, it is extremely suitable for controlling ticks.

ある。[0006] dissolution rate of B 2 O 3 is a vitreous material and a particle size in distilled water at 20 ° C. for example 420 to 600 [mu] m was immersed for 1 hour, calculated as B 2 O 3 by weight per vitreous material 1g To be done.
However, in the present invention, the particle size is not limited to this. In the present invention, the dissolution rate of B 2 O 3 is 1 mg / g to 300
The reason why the mg / g was set is that if the dissolution rate is lower than this, there is no insect repellent effect, and conversely, if it is higher than this, there is no change in the insect repellent effect, which is wasted, and the dissolution is completed in a short time ..

The method and the method of producing a film by kneading fine powder of a vitreous substance into the raw material of the film from the beginning are common. The insect-repellent film of the present invention thus obtained has the effect of laying it under a tatami mat or the like to prevent mites and the like.

That is, the above sample was laid on the bottom of a plastic petri dish (area: 28 cm 2 ) so as to be in intimate contact, and 0.025 g of a medium containing Dermatophagoides farinae was uniformly spread on the surface. The number of surviving mites in the medium is previously counted by 0.1 g by a saturated saline suspension method immediately before the start of the test. Put a saturated saline solution in each treatment area of the plastic petri dish and keep the humidity at 75%.
Store in a plastic container for food storage kept at
The animals were kept in an incubator at 25 ± 1 ° C. Similarly, the animals without the sample were raised as a control group, and 14 days later, the total number of living mites in the petri dish was investigated, and the insecticidal rate was calculated by the following formula by comparison with the number of living mites in the control group. Insect kill rate (%) = [(number of mites in control plot-number of mites in treatment plot))
/ Number of mites in control section] The test was carried out in three sections and one section. Test Results The insecticidal rate of each sample is as described in Table 1 above.
