Pest control companies have been able to come up with brilliant ideas and solutions on how to effectively control pets in such a way that they do not cause harm to people and the environment. The method of control is by the use of natural and organic materials to control pests. It has been found that extracts of some plants are capable of repelling pests and causing them to leave a particular environment. Termites (ปลวก) and some other pest like mice respond to this method of control. These pests will naturally take their leave when they smell extracts from such plants.
