Background
In recent years, the situation that the dam is broken due to termite damage is happened in various places, and the situation that the dam is dangerous due to termite damage is more common.
When the soil dam is bred, the main nest cavity of the mature nest group is generally 60 cm multiplied by 50 cm multiplied by 60 cm (length multiplied by width multiplied by height), the large area digs more than 1 cubic meter of soil in the dam, tens of satellite nest cavities with different sizes or even hundreds of satellite nest cavities are arranged around the main nest cavity, the main nest cavity is communicated with the satellite nest cavity, and the depth of the main nest cavity in the dam is usually about 2 meters or even deeper. Therefore, on one hand, the integrity of the dykes is destroyed, and the resistance of the dykes is reduced; on the other hand, the large termite-tunnel opening excavated by the main nest cavity is large in diameter, the termite tunnel penetrates through the inner slope and the outer slope of the dam, once the water level exceeds the normal water level, the pipe leakage risk is often caused, and the dam dam collapse is caused when rescue is not in time or is improper.
There are two traditional termite control methods: firstly, spray the prevention, it takes time and labor to pollute the environment, secondly dig nest and kill termite, it takes time and labor to kill termite, pollute the environment, and it is difficult to thoroughly radically cure termite. At present, baits are used for killing termites, and although the baits have certain effects, the problems of easy mildew and loss of active ingredients generally exist, and particularly outdoor effects cannot be achieved at all.
Based on the above, it is highly desired to provide a termite control composition which is durable in attracting effect and not liable to mildew.
