How to control red fire ants? What are the reasons for the spread of red fire ants?

The red fire ant is a kind of ant that is harmful to human. Once bitten by this ant, the wound will be red, swollen and inflamed. So how to control red fire ants? Let's take a look.

The control of red fire ants is not only carried out by environmental protection, agriculture or epidemic prevention units, but also because of different land authority and responsibility organs, such as land belonging to education or transportation departments, the existing red fire ant population needs to be controlled and treated by the units themselves. however, due to the lack of communication between the treatment progress and the time of applying bait, under the separate use of bait or poison, the control effect may not be as good as expected, resulting in the fire out here. There's a fire somewhere else! Lin Zongqi said that Taoyuan City and New Taipei City have the practice of integrated control of red fire ants across units, with good results, and other counties and cities can consider following up.

Lin Zongqi said: with the current area of more than 76000 hectares of red fire ant control area in the country, the peach orchard, which used to be the hardest hit area, has implemented the red fire ant control project, so the red fire ant infestation area has become smaller. Lin Zongqi stressed that the red fire ant queen has wings and spreads the ant colony by flying, so the prevention and control of red fire ants should be coordinated by the local government and the prevention and inspection bureau to achieve cross-regional prevention and control, so that the red fire ants should not feel nothing until they arrive at home. I was surprised to realize that the situation was serious only when the epidemic spread in our own family.

When carrying out earthwork or planting movement operations, if the soil used is contaminated by red fire ants, the spread of red fire ants will be accelerated. Therefore, some public works projects will specify that a certificate of no red fire ants must be obtained when drawing up contracts. However, Lin Zongqi said that due to the shortage of manpower in the National Red Fire Ant Control Center, many inspections of red fire ants are carried out by local governments, so some certificates of no red fire ants are issued by local governments, Lin Zongqi said frankly. It is "very strange" for people with insufficient expertise in red fire ant control to issue a certificate without red fire ants.

In addition, some projects will open "no red fire ant cut knot books" to show the safety of the soil used for engineering and planting. Lin Zongqi said that in practice, most of the cut knot books are not accompanied by experts. the site director is directly responsible for independent inspection and signature, so it is often seen that there are red fire ants on the earth, but the flow direction of the earth with red fire ants cannot be controlled, Lin Zongqi stressed. According to the standard operating procedures for the detection, control, planting and earthwork movement of red fire ants in the construction base, engineering units must manage and inspect red fire ants independently, but in the absence of supervision mechanism, it is difficult to implement the prevention of red fire ants.

Biological regulators are often used as baits to control red fire ants, which requires a lot of money and manpower. Xu Chunliang, head of the Agricultural Section of Miaoli County, said that at present, red fire ants have been found in many towns and cities in Miaoli County, with a raging area of about 1300 hectares. and the area has an expanding trend. This year, a budget of 300000 yuan has been obtained for the control of red fire ants, together with local cooperation funds, the first municipal government office has added 800000 yuan and Nanzhuang Township 100000 yuan. Due to the lack of funds and limited manpower, the control of red fire ants is very difficult.

Xu Chunliang pointed out that the invading red fire ants will spread through various ways, such as the queen will move by flight, or the ant colony will be planted through seedlings and earthwork. Judging from the track of the invasion of the red fire ants in the past, it gradually spread all the way south from the Taoyuan area. In the past, the line of defense was in Hsinchu, but after the fall of Hsinchu county and city, the line of defense for the control of red fire ants moved south to Miaoli, but there were many hilly terrain in Miaoli area, so it was not easy to spray pesticides by manpower. Due to the lack of manpower and funds, it is difficult to completely exterminate red fire ants.
