A noteworthy linguistic phenomenon is that the commonly used term in foreign literature is not rodenticide, but rodenticide. The differences in words show the differences in the understanding of rat harm at home and abroad and the guiding ideology of related work. The concept of "rat prevention" itself contains a denial of "rat prevention" to some extent. It saw the impossibility of eliminating rodents, so it took more scientific and pragmatic measures to minimize the harm of rodents.

The rationality of "rat control" is mainly based on the understanding of two facts. On the one hand, face up to the * * * relationship between mice and humans (symbiosis, which also means * * * food). All kinds of foreign scientific documents about rodenticides emphasize this point when introducing the target rodents. Mice have been born with people for a long time, which is the result of natural selection and evolution, and its strong vitality can not be destroyed by "extinction"

This can be seen from the short-term effect of bromadiolone and the recovery of rats. On the other hand, the fundamental purpose of rodent control is to control rodents, not to eliminate them. In the context of "deratization", deratization is equivalent to eliminating its harm, but this is not the case. For example, the health risks caused by outdoor rodent activities are different from those caused by indoor rodent activities. A certain degree of rodent activities does not mean the harm of rodents, so it is not the same as killing individual rodents at will to reduce the harm of rodents.

Based on the above two aspects, the work of "rodent control" is to establish the relationship between rodent activities and these rodent pests from the evaluation of rodent pests, and then establish the population control objectives of rodent pests under different conditions. Although the original intention of "killing rodents" is the same as that of "controlling rodents", it simplifies the understanding of the relationship between rodents and rodents, so it simply aims at eliminating rodents. Killing rats blindly, too much, will lead to the waste of social resources and may also cause unexpected problems.

Several scholars' papers also reached the same conclusion: simply poisoning is not a long-term solution, because the rodent population has a strong ability to restore the number. Especially when the environment suitable for its habitat remains unchanged, the impact of rodenticide on rodent population will not be great. To make matters worse, with adequate food and good cave conditions, rats may easily avoid rodenticide, thus making their population more stable.
