1.Title of Patent

 Development of a mat made of natural components for enticing and trapping mites

2. Meaning of this invention technology

 As mentioned in the Introduction to the product, there's a limitation to the ability to exterminate mites and their carcasses by using mite-repellents, insecticides, vacuum cleaners, and mite-shield covers and repellents and insecticides may also aggravate allergies. Therefore, the most effective method proposed to eliminate house dust mites is to lure the mites into one area and kill them during a certain period of time and then discard them.

 We developed a substance that will lure the mites by combining fragrant substances that mites are most attracted to. Also, we created an environment from which the mites, once they are lured, cannot escape. Further, we developed food that was made of natural materials and placed it inside the mat to kill the mites. Therefore, this is the meaning of this invention.

4. Particulars of patent invention technology

4-1. Research on reactions of mites to various aromatic materials

 Although insects are lower class animals, they have an ability to find instinctively the conditions that

they like. This characteristic is used to exterminate house insects by the use of light, smell, or substances such as pheromone. Mites prefer to live in dark places, as their sense of smell is much more developed than their sense of vision or touch. Hence, to analyze and combine substances that mites would prefer, we experimented with single substance such as geraniol, terpineolen, nerol, geranial, neral, citronellol, and citronellal. The mites did not show any kind of reaction to these single substances. On the other hand, they started showing certain reactions when they were exposed to a single aroma such as geranium and jasmine. They reacted to basil, bergamot, cypress, and geranium, among others, but overall they did not react aggressively against other single aromas. The pheromones of animals and insects have many different characteristics and can be separated into many different combinations just as there are lots of different insects and information about them. If pheromone consists of different substances, respectively, there might be a low possibility that different insects would react to different pheromones. However, there are many cases where a compound substance is used as a pheromone for different kinds of animals. So, the composition ratio should be different for accurate transmission of information for each kind of animal. Therefore, to fundamentally prevent confusion about cross-reaction and to form specific characteristics, the composition ratio should be different for each characteristic. For this reason,

we found that mites do not react to single substances. Hence, we developed an aroma that attracts mites by combining different kinds of aromas.

4-2. The formation of a mite-luring aroma

When aromas were combined to a certain ratio as shown in table 5, the mites showed a high preference and the aromas were effective in luring mites.

4-4. Activity of mites according to temperature

Activity at 20℃

Activity at 24℃

Activity at 28℃

Activity at 32℃

It has been known that the most adequate temperature for the activity of mites is 20~30°C. Because mites cannot control their body temperature, they are very sensitive to external temperature and they remain stationary when the temperature does not reach their activity level. So a little heating up is needed to help lure the mites. In addition, the mites have a tendency not to show themselves but rather they hide inside deeper and deeper, which makes it difficult to exterminate them. To solve these problems, it is essential that the temperature is maintained at an adequate level for the mites and that there should be adequate luring substance and food.

4-6. Structure of the mat

The mat, designed to lure and slowly exterminate mites, provides an optimal living environment for mites since the mat contains the luring substance, food, and the heating substance. Once a mite comes into the mat, it stays there until it dies. Hence, the mat must be made with a material that can preserve the luring substance, food, and aroma, and it has to be made of a natural fibers that allow easy access to the mites, with good ventilation and breathablilty. Furthermore, considering the living habits of mites, the external surface area must be large with intervening space or interstice and the inside should be made in a flat form to prevent the mites from escaping. Accordingly, a cloth for circular knitting was selected since it forms loops. The outer cover was made of 20-denier combed cotton and the loop was made of 10-denier cotton. The inner cover was made of 30-denier combed cotton and the loop was made of 20-denier carded cotton to prevent the escape of the mites that enter the mat.

Inside the mat, the mite-luring aroma and food was combined in a certain ratio and placed in the middle of the mat, and then the mat was sealed.
