How to eliminate ants invading the room?

Recently, many readers have reported that many red-brown ants have appeared at home this year, and some families have been disturbed to their normal lives. In order to prevent the invasion of ants, many families pack food and hang it high, and "keep the walls clear" for red ants. Many citizens bought many drugs to kill ants, but the effect was not satisfactory. Experts from the Beijing Center for Disease Control and Prevention explained that the drought in Beijing this year was the main reason for the flood of red ants. At present, the main ant invading Beijing residents is the little red ant, also known as the little yellow beetle, which is small in size and only about 1.5 to 2 mm in length. The life span of female ants is about 15 years, while that of male ants is shorter. Experts pointed out that this little red ant generally carries various microorganisms, such as Shigella dysenteriae, and bites people, especially infants. If children have milk stains, they are easily bitten by little red ants. Little red ants are sensitive to temperature, and most of them 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 ant bait has special effects on this kind of ants. ) Red ants are mostly killed in kitchens with greasy food. This property can be used to kill them. Before going to bed at night, remove all the food where the ants can't go, then put a piece of fat pork on the ground and prepare a boiled water in a thermos. The next morning, the ants gathered on the fat pork and had a delicious meal. Don't be surprised. These invasions are very cunning. Although they can be seen everywhere, we seldom pay attention to them, including the losses they bring. Maybe it's because they are too small to attract attention. These intruders are wandering ants. Wandering ant is a kind of ant, which is closely related to human beings and is often brought to all parts of the world with goods. They hide in our factory goods, packaged goods, building materials and heavy machinery, such as measuring or military supplies, and travel around the world. Usually, stray ants only enter the destroyed environment and do not set foot in the intact natural habitat. However, with the expansion of the impact of human activities on nature, the range of activities of stray ants has also expanded. The ecological importance of most stray ants has not been recorded, but several species are known to have great influence on the environment. Once these ants enter a new area, the whole biological community becomes like this: the original invertebrates are completely replaced by species that can live with ants. The disappearance of the original important invertebrates (such as important food sources, pollinators, scavengers, etc.) ) caused a serious chain reaction, leading to the chaos of the natural food chain until more primitive creatures became extinct. Humans have a tendency to kill most animals in nature, and ants help humans get rid of what is left in nature. Out of sight, out of mind, most of these losses are neither evaluated nor recorded. In America, the most famous invading ant is the red ant. It originated in South America and was introduced to the United States at the beginning of this century. First of all, it spread from the southeast where nature was destroyed by human beings to the inland, causing huge economic losses. In the area occupied by foreign ants, red ants account for 99% of all ants. It killed almost all invertebrates, climbed the tree, and killed the female birds and reptiles that were hatching eggs by attacking the softest parts, especially the eyes. In the southeastern United States and Puerto Rico, this red ant is also the killer of hatching turtles. The harm caused by red ants is not unique. Giant ant pheidole megacephala and long-legged ant anoplolepis gacilipes are both ants that originated in Africa and now spread all over the tropics. In the lowlands of Hawaii, many endemic species have become extinct due to the participation of these two ants. Argentine ants native to South America are the most important pests in subtropical and temperate regions, including the Mediterranean, South Africa, Australia, Bermuda and the southern United States. They attack invertebrates and vertebrates. Argentine ants also came to Hawaii and became the main pests in plateau areas. Wasmannia auropuncta, a little red ant, is another major pest. Although it is not widely spread outside the native tropical America, its deadly attack on vertebrates is a huge potential threat. On the ancient island of Graba, little red ants attacked local species, including giant turtles. It not only attacks their eyes, but also attacks their cloaca, making them lose their reproductive ability. The little red ant also attacked Melanesia, and the result was disastrous. In Solomon Islands, it is reported that many dogs were blinded by ant venom and died five years later. Little Red Ants also attack local invertebrates, including brooding birds on Savo Island. Many characteristics of stray ants determine their success in the world: there are many queens in the ant colony, allowing some ants in the ant colony to form new ant colonies. In addition, there is no obvious boundary between groups, so super-large groups can be formed, covering a wider area. In this way, soon, the number of stray ants surpassed that of well-defined local ants. Also, after arriving in the new world, wandering ants left their original natural enemies behind. Chemical control can play a role in dealing with small islands and local invasive ants. But it is not advisable to use chemical methods on a large scale. There are many reasons. In addition to the toxicity to non-target animals (including ourselves) and high financial consumption, chemical methods actually increase the spread of stray ants, because stray ants are more adaptable and competitive than local ants. Many research groups are studying the use of natural enemies to control red ants in the United States, and the same method can also be used to control ants everywhere. Wandering ants even entered "Biosphere 2", which is a huge artificial ecological environment greenhouse built in Arizona to study the future survival of human beings in space. Now, on the building of Biosphere 2, a wandering ant from the old world, paratrechuia longicornis, was flooded. Biosphere 2, which was originally rich in species, is now rare in species. The only surviving species are those organisms on which ants depend. (scale insects that love ants, etc. ), highly ant-resistant organisms (isopods and millipedes), or tiny animals that ants cannot attack (such as mites). It can be seen that if human beings do not pay attention to the problem of ants now, the present situation of "Biosphere 2" is the epitome of our future. Little Red Ants-A New Family of Urban Pests Not long ago, officials in Sarasota, Florida, said that an 87-year-old woman who had been living in a nursing home with Alzheimer's disease died in her own bed after being bitten by ants 1625 times. She was bitten by red ants in a large area, and there were traces of ants on her chest, upper arm, abdomen and back. In Beijing, in recent years, the little red ant has also threatened people's normal life in hospitals and residential buildings. Baby diapers, feminine products, food, bottles, etc. are contaminated by ants from time to time. Some famous entomologists in China exclaimed that house ant has become another serious urban pest after the four pests. Ants are common insects on the earth, and there are many kinds of ants. There are more than 9000 known species in the world, belonging to more than 360 genera, and the number of individuals is also amazing. There are more than 10 15 ants on the earth. Ants live a long life. Worker ants can live for several weeks to 3-7 years, queens can live for more than ten years or decades, and an ant nest can grow for 20-30 years in one place. Little red ants in residential areas, they are small and breed quickly. The season when ants leave their nests is April ~165438+10 in the south and May ~ 65438+10 in the north. June, July and August are the peak seasons for ants. Little red ants like sugar, honey, sweets, oil and cooked food. If you eat the patient's pus and sputum, it will directly carry and spread germs, such as harmful bacilli, dysentery bacilli, Yersinia pestis and so on. Little red ants can also bite the skin of people and pets, causing erythema and itching, and in severe cases, they can bite people's skin and cause bleeding. Patients or babies at home should pay special attention to the prevention and control of domestic ants. Domestic ants can be prevented by physical means, such as flooding and blocking ditches with washing powder. Chemical control, such as dust, pesticides, poison bait, etc. , can achieve a certain control effect. The best way to eradicate the little red ants at home is to choose palatable bait, so that the worker ants can be transported into the nest, and the queen, male ants and worker ants will kill the whole nest after eating. In order to prevent the invasion of little red ants, Beijing Taiming PCO has developed an attractant that little red ants like to eat. Through the household test, the killing effect of 100% has been achieved, and it has never been invaded by little red ants since the whole nest was killed. There are many kinds of ants in nature, which not only have a good ecological balance, but also have good nutrition for health care, food and medicine. Rational development of ant resources is also a very meaningful work. Clean the house without bugs. It's warm and cold at first, and the room is full of spring. At this time, if a cockroach or ant calmly crawls across the table in front of you with the attitude of creating an intruder, your feeling of leisurely home will vanish instantly. How can we prevent common pests and finally eliminate them? Don't blindly believe in all kinds of pesticides. Chemical things are not good for the human body. The less you use, the better. As advocates of environmental protection, we might as well carefully study the habits of various pests and traditional methods of elimination, and try our best to use natural and environmental protection methods to eliminate pests at home with little or no pesticides. This is our goal. 1. The ugly behavior of crawling cockroaches reveals that there are at least two kinds of common cockroaches, one is small and the other is big and can fly. No matter what kind of cockroaches, their backs are shiny and extremely disgusting. In addition to its disgusting appearance, it also spreads a variety of germs, which spread through the body and excrement, making people sick. The most common pathogens are Salmonella and Escherichia coli. But the most hateful thing is not here. Hatefully, the chances of completely destroying them are extremely slim. Generally, if you find a cockroach in sight, there must be at least forty or fifty cockroaches at home. -I want to vomit when I think about it! But you have to live under the same roof with them all day, "eat" and "live". Criminal's whereabouts: Cockroaches like to hide in warm and food-rich places. It is said that they especially like "oil", and greasy dim sum dishes are especially to their taste. Usually they are hidden in the dark corner of TV, computer and kitchen, which is difficult for people to deal with. Chemical Raiders: Of course, using DDT to kill them is effective, but it will do harm to the human body, which is not worth the loss. The spray used to kill reptiles is relatively less toxic, but it also has chemical residues. Therefore, you must be careful when using it, and you can't just spray it. The correct way to use it is: 1, spray it along the corner, the four sides of the house and the joints of the wall, and it will take effect in a few hours. 2. Spray on the floor where cockroaches pass. Don't wipe the floor immediately after spraying. Let the medicine play for a while. 3. Don't use cockroach spray and cockroach paste to trap cockroaches at the same time, so their effects will offset each other and reduce the efficacy. All cockroach sprays only treat the symptoms, not the root cause, and eliminate the living environment of cockroaches. Experts suggest that recently, the vector insect department of Shandong Provincial Health and Epidemic Prevention Station receives a consultation call about ants every day: How to eliminate the small yellow ants at home? Why are there many ants after using the ant-killing medicine bought in the store? Can ants in the room spread diseases? This kind of ant is very small, and its body is red or red and yellow. It's called Xiao Huang Jia ant, also called domestic ant. Because this little yellow house ant disturbs people's lives and spreads many diseases, it is also a pest. There are 245 species of ants in China, and indoor harmful ants are 1 1 species. There are small yellow ants and big head ants in indoor activities in our province, but from the collected specimens, small yellow ants are the main ones. Ants like sweets best. They can eat anything that people eat, and eat dead insects, such as ground turtles, flies, crickets, beetles, bees and so on. And also addicted to purulent blood, diseases, animal blood substances. Because indoor ants crawl around in the process of foraging and come into contact with various infectious substances, they can mechanically carry various pathogenic microorganisms, such as Staphylococcus, Streptococcus, Bacillus, Salmonella, Typhoid Bacillus, Dysentery Bacillus, Tuberculosis and so on. , and can spread viral diseases such as hepatitis A and hepatitis B. In hospitals, yellow ants can also cause cross infection. Small yellow house ants disturb people's sleep, especially children and seriously ill patients. Because ants are foraging in people's rooms, crawling around, polluting food, tableware, bedding and clothes, causing people's emotional anxiety; After being bitten by small yellow ants, it often causes papules, erythema and itchy skin, especially the secretions of infants and young children are attractive to ants and are more likely to be bitten. In recent years, the number of indoor ants is increasing, and the harm is becoming more and more serious. The reason is related to indoor decoration, constant temperature and humidity. In order to effectively control the number of ants, we should not only kill worker ants, which will only lead to the increase of asexual reproduction, but also choose agents with the following characteristics: ① chronic toxicity; ② Good killing effect and slow death; ③ No repellent effect. Adopt the method of "local application". In the room, the fresh food that the little yellow house ants like is used as bait, and drugs with chronic toxicity are mixed into the bait, which are put in several places where the little yellow house ants often move, and the worker ants move back to the ant nest after feeding, thus killing all the little yellow house ants in the ant nest. If the toxicity is too great, worker ants may die without transporting food back to their nests. There are stomach poison types in the bait on the market now. Where there are many ants indoors, the method of "residual spraying and poison bait" can be adopted, and the method of partially killing ant poison bait can be adopted indoors. In addition, try to control the source of food. Control the number of ants indoors to the maximum extent, reduce the worry of ants and ensure people's health. |
