Order of the ministry of construction no. 130 "regulations on the control and management of termites in urban housing"

Article 2 these provisions shall apply to the control and management of termites in urban houses in areas where termites are harmful.

The term "control and management of termites in urban houses" as mentioned in these provisions refers to the control over the prevention of termites in newly-built, rebuilt, expanded and decorated houses and the control over the inspection and treatment of termites in original houses. Termite prevention must be carried out in new buildings, remodeling, expansion and decoration in areas endangered by termites.

Why termite prevention should be carried out in house decoration

As the ceaseless rise of people's life and the improvement of working, living environment, host undertakes decorating to bridal chamber mostly, but whether did you hit a dose for it before decorating "needle of precautionary moth"? Because a large number of wooden products such as wood archives, wood floors and clapboard are used in the decoration, they provide a broad and rich food source for termites' habitat and reproduction. And the change of living habits of termites with the warming of the climate greatly enhances the adaptability of termites to the environment, resulting in the frequent occurrence of termite hazards after the decoration of various houses.

Current resident decorates commonly cost does not poor, little criterion tens of thousands, much criterion tens of thousands, hundreds of thousands, if ignored termite and the prevention and cure of other borer, once produce harm to be very regrettable really. Although a lot of families also realized the importance of insect-proof when decorating, but the method that take is improper, buy camphor bolus mostly, lime and other medicaments to wait to sprinkle below wooden floor, these medicaments can have short-term drive avoid action to borer only, go up from fundamental the effect that does not achieve pest prevention.

So when the house is decorated, ask professional control orgnaization to undertake termite prevention processing, achieve "spend small money, prevent big trouble" purpose

Prevention and treatment of termites in house decoration

In order to fundamentally control the harm of termites, we should put prevention first, combine prevention with prevention, and carry out comprehensive prevention and control policy.
