For this reason, many methods have been used to exterminate termites, but it is often thought to take measures after suffering a serious harm from termites. Ideally, termite damage should be detected and controlled to a minimum before it can cause actual damage to humans. Termite control devices are currently commonly used to monitor and kill termites.

In the prior art, the termite monitoring and controlling device integrates an IPM technology, IPM is an abbreviation of Integrated Pest Management, Chinese means comprehensive Pest control, and in recent years, the technology is widely applied to the field of termite control. Compared with the traditional toxic soil barrier method, the IPM technology has great advantages, but after the termite monitoring and controlling device integrated with the IPM technology is buried underground, all devices need to be checked for 1-2 times every year or even every month, if the target area is large, the number of buried devices is large, the searching is difficult, the checking workload is large, the labor investment is large, the labor is large, and the labor cost is high. The phenomena of damage and serious loss of part of underground monitoring devices are caused by green land transformation, ground weeding and garbage mess, and meanwhile, difficulties are brought to inspection and maintenance due to bush around the monitoring devices. Although the IPM technology can reduce the use of medicines on a large scale, the pain point of no large-scale popularization is that the manual inspection cost is high.
