The harm of black ants? How to remove it?

Ants are sensitive to temperature, and most ants are active in hot weather. They like sweets, such as cakes, honey, maltose, red ponds, eggs, stones, skins, dead insects and so on. They can tell the direction and act quickly. If individual worker ants die, their bodies will be transported back to the nest. But they are not hungry. Without food and water, after four days and four nights, half of them will die. Experts suggest that household ants can be flooded with boiling water first, and then put into the ditch with washing powder for plugging. It can also be used as a spray to kill cockroaches and mosquitoes. These drugs have the efficacy of killing little red ants. But the little red ant is a semi-social insect, and the general spray can only kill the workers who leave the nest. The queen and the queen are still breeding wildly in the nest. An ant queen can give birth to 600 small ants every second, so it is ideal for the whole building to take collective action to kill ants. The best way is to choose bait with good palatability and no repellent effect on ants. After the worker ants bring the bait back, they can poison the queen, the larvae in the queen's nest and destroy the whole nest. (Taiming: Taiming's ant bait has special effects on this kind of ants.) Use the characteristics of ants to kill: ants can be used to kill where there is greasy food in the kitchen. Before going to bed at night, move all the food where ants can't go, then put a piece of fat pork on the ground and prepare a cup of boiling water in a thermos. The next morning, the ants gathered on the fat pork and had a delicious meal. Don't. Scald to death with boiling water immediately. It can be eliminated after a few times. ■ Species of indoor ants and their control methods. The harm of indoor ants to home is often overlooked. After investigation, indoor ants mainly include yellow ants, big-headed ants, stone ants, smelly ants, etc., and often nest in roadside, corner and wall cracks. The main ways of harm are stealing food, biting people and spreading bacteria. According to their activity characteristics, some physical and chemical methods can be used to prevent and control them, such as blocking the activity route. Block the nest, etc. If possible, it can also be controlled by biological hormones. Ants belong to Arthropoda, Insecta and Hymenoptera. Although there is only one family (Formicidae), there are more than 360 genera under it, and it is estimated that there should be about 14000 species, and there are about 300 species in China. They are widely distributed, from desert to forest, from tropical to cold zone, from plain to mountainous area. All kinds of animal and plant carcasses and organic residues can be their food. Therefore, it can be considered that ants have strong adaptability to different environments. Now, with the rapid development of our urban construction, the living environment of ants has undergone tremendous changes. They gradually adapt to the urban environment with dense buildings and dense population, and often invade indoors for food and nesting. Because indoor ants can pollute food, destroy buildings, spread bacteria and bite people, they will do some harm to human life. In order to prevent and control this kind of harm better, we must know the species and habits of indoor ants, and then put forward some effective measures according to the specific situation. ■ Materials and Methods: According to the investigation and statistics of common pests in families, there are mainly four kinds of ants, namely, small yellow house ant, big head ant, Rockwell social ant and smelly ant. Through the analysis of the characteristics of these four ants, although their harm is far less than that of cockroaches and flies, they are still a hidden danger to families. Therefore, according to the characteristics of digging holes and leaving a special chemical smell on the moving path, the following methods can be used to remove them: ○ Wipe with a wet cloth: if one or more rows of ants are found moving, wipe with a wet cloth and put them into a basin filled with washing powder water to drown; ○ Washing powder ditch barrier: Because ants will drown as soon as they enter the washing powder water, this method can be used to protect a certain area; ○ Flooding: that is, watering floods the ant nest, which is more suitable for ants to nest in flowerpots. ○ Chemical control: Dust: Inhaled dust such as silicic acid (silica) powder is usually used to make ants die of lack of water; ○ fenvalerate silicate powder mixture: This method is an improvement of the previous method, which can shorten the killing time, but fenvalerate itself or dust should be avoided from being inhaled indoors; Spraying chemicals around the nest mouth and on the ant path can directly contact and kill ants. This method is easy to cause environmental pollution and resistance. The commonly used chemicals are: more than 90% trichlorfon stock solution is sprayed with 500- 1000 times solution; 50% DDVP EC or 80% DDVP EC 1000- 1500 times, 2000-3000 times; 0. 1% pyrethroid kerosene solvent spray, etc. These methods are effective and quick, but they are not thorough, difficult to eradicate, and easy to cause environmental pollution and drug resistance. Poison bait: Poison bait is a mixture of chemicals and food bait that ants like to eat. According to the mating behavior of ants, a worker ant can bring poison bait into the nest as long as he doesn't die in a short time. Generally, the death time is within seven days, but the pupae of ants may survive without eating, which leads to incomplete extermination of ants. Juvenile hormone analogue bait: that is, juvenile hormone analogues, such as floxuridine and methoxyprene, are mixed in the bait, and the hormone concentration is generally 0.6% ~ 1.5% of the weight of the bait. At present, it is under development. There are ants in the closet. You can put some vegetables such as parsley and celery to drive away the ants. Put some walnut leaves, tobacco and peppers in places where ants often haunt, which can drive away ants.
