Background
Ants are insects belonging to the phylum arthropoda, class insecta, order hymenoptera, family formicidae. Ants are sensitive to temperature and mostly move in hot weather. South province, especially Hainan province, is particularly suitable for the generation and reproduction of ants due to hot weather all the year round, and the ants have serious harm to agricultural production, human beings and livestock. The harm of ants can disturb human body, spread germs, pollute environment and damage buildings. The method mainly comprises five aspects of stealing and polluting food, damaging wood and wasting various materials; secondly, ants can damage buildings such as dams, houses, doors and windows and the like; thirdly, ants can eat sowed seeds and seedlings, so that the seedlings lack and ridges are broken, and the ants often need to sow again or replenish the seedlings; fourthly, when ants crawl around, pathogens such as various bacteria, viruses and the like can be brought to food to spread diseases; and fifthly, some kinds of ants can bite and attack people directly to cause injury, particularly the red fire ants.
There are two types of conventional ant control methods: one is a physical method, which comprises soaking in boiling water, and then putting washing powder into ditch to block. The physical method can only kill the seen workers and ants, but can not break the roots. The other type is to use chemical pesticide or chemical insecticide to kill the termites, and the chemical pesticide is in the forms of powder, aerosol, liquid, etc., but the chemical pesticide can only kill the termites living in nests in the colony. The two methods can only eliminate visible worker ants, and breeding machines such as the ant backs and the ant queens which are deeply positioned in the holes still breed in the nest crazy, so that the ant queens cannot be removed, and the worker ants are continuous and inexhaustible. There is an urgent need for a control method that is human and animal and environmentally friendly and that can kill the entire colony.
