Is spraying high chloride propoxur on the wall harmful to people's health?

Sometimes, our house is infested with small yellow ants. Whether they are on the kitchen floor, on the stovetop, or on the wall, there are small yellow ants. Even the bed and body of a bedridden old man are covered with small yellow ants. And the number is chilling. I have taken many methods: using sugar, honey, etc. to lure them out and eliminate them intensively; using camphor powder to sprinkle around the bed; mobilizing everyone to crush ants with their hands, find ant nests, and scald them with boiling water... but nothing happened. It only has short-term effects and cannot be eradicated. In desperation, I was introduced to a medicine and the problem was solved in one go. Now introduce it to you.

The name of the medicine is "Anticide", which is produced by the Guangdong Provincial Institute of Entomology. It is not a three-no product. It has a drug registration certificate number and the address of the manufacturer. Effect guarantee: no ants for three years. Each small packet can kill 1-2 ant nests. Divide 3-4 portions of each packet and place it on the path where ants pass by. After the ants return to their nests and eat, they will infect each other and die within 2-3 days. The effect is particularly obvious. We only used two packs. After using it, we haven’t found any ants so far. And the price is very cheap, only one yuan per small package. You can usually buy it at flower markets where fertilizers and pesticides are sold. Because when using it, the medicine is placed on the path where ants pass by, away from human food, and we will not easily come into contact with it. There is no risk of poisoning, so you should try it.

■Home Ant Control Guide■

Ants are sensitive to temperature and are mostly active in hot weather. They like sweet foods, such as cakes, honey, maltose, red tang, eggs, fruit cores, meat skins, dead insects, etc. They can identify roads and move extremely hurriedly. If an individual worker ant dies, the body will be carried back to the ant nest. But they are intolerant of hunger, and half of them will die after 4 days and nights without food and water.

Experts suggest that household ants can be controlled by first soaking them in boiling water, and then using washing powder to block the ditches. You can also use sprays that kill cockroaches and mosquitoes. These drugs are effective in killing small red ants. However, little red ants are semi-social insects. General sprays can only kill the worker ants in the colony that move out of the nest. The breeding machines of the queen and king are still breeding crazily in the nest. A queen ant can give birth to 600 ants every second, so it is ideal to take collective action in the entire building to eliminate ants. The best way is to choose a chemical poison bait that is good in palatability and has no repellent effect on ants. After the worker ants move the poison bait back, the king, queen and larvae in the nest will be poisoned to death and the entire nest will be destroyed.

(Taiming: Taiming's termite bait has special effects on this species of ants)

Use the characteristics of ants to eliminate them:

Ants are mostly found in the kitchen where there are oily foods, so you can use them This feature will eliminate it. Before going to bed at night, move all the food to a place where the ants cannot reach, then put a piece of fat pork fat on the ground, and prepare a thermos bottle of boiling water. The next morning, ants gathered in the fat meat When the fat is delicious, don’t scare away the ants. Immediately scald them to death with boiling water. Do this several times to eliminate them.

■Types of indoor ants and their control methods

Indoor ants are good for The harm to the home is often ignored by people. According to the survey, indoor ants mainly include small yellow house ants, big-headed ants, Lowe's ants and smelly ants. They often nest on the roadside, corners and wall cracks. The main way of harm is to steal food. Bites and spreads bacteria. According to its activity characteristics, some physical and chemical methods can be used for prevention and control. Such as blocking activity routes, blocking nests, etc. If conditions are feasible, biohormones can also be used for prevention and control.

Ants belong to the phylum Arthropoda, the class Insecta, and the order Hymenoptera. Although they have only one family (Formicidae), there are more than 360 genera under it. It is estimated that there are about 14,000 species, and there are about 300 species in China. And they are widely distributed. They are found from deserts to forests, from tropics to frigid zones, from plains to mountains. Ants have a variety of food habits, and various animal and plant corpses and organic residues can become their food. Therefore, it can be considered that ants have strong adaptability to different environments. Ability.

With the rapid development of our urban construction, the living environment of ants has undergone tremendous changes, and they have gradually adapted to the densely built and densely populated urban environment. They often invade indoors for food and build buildings. Because indoor ants can contaminate food, damage buildings, spread bacteria, and bite the human body, they will cause certain harm to human life. In order to better prevent and control this harm, we must understand the types and habits of indoor ants, and then Some effective methods are put forward according to specific situations.

■Materials and methods:

After survey and statistics on common household pests, the ants mainly include small yellow house ants, big-headed ants, There are four types of ants: social ants and stink ants. Through the analysis of the characteristics of these four ants, although their harm is far less than that of cockroaches, flies, etc., they are still a hidden danger to the home. Therefore, special precautions are left on their burrows and activity paths. Chemical odors and other characteristics can be removed by the following methods:

○Wipe with a damp cloth:

If you find one or more rows of ants moving, wipe them off with a damp cloth and put them in a container. Drown them in a basin of washing powder water;

○ Washing powder ditch barrier:

Since ants will be drowned as soon as they enter the washing powder water, this method can be used Protect a certain area;

○Flooding:

Use watering to flood the ant nest, which is more suitable for ants nesting in flower pots.

Dust: Inhalable dust such as silicic acid (silica) powder is usually used to cause the ants to die due to lack of water in the body;

○Mealypteryx silicate Ester powder mixture:

This method is an improvement of the above method and can shorten the killing time, but you should avoid inhaling the powder yourself or inhaling the dust into the room;

Chemical agents Spraying chemicals around the entrance of the ant nest and on the ant paths can kill ants in direct contact

This method can easily cause environmental pollution and resistance. The commonly used chemicals are as follows:

More than 90% of the ants are killed by spraying chemicals. Spray 500-1000 times of the original solution of Dichlorvos;

50% dichlorvos emulsifiable concentrate or 80% dichlorvos emulsifiable concentrate 1000-1500 times, spray 2000-3000 times;

0.1% pyrethrin Kerosene solvent spray, etc.

These methods have better results and are effective quickly, but they are not thorough, difficult to eradicate, and can easily cause environmental pollution and resistance.

○Poison bait: < /p>

Poison bait is a mixture of chemicals and food baits that ants like to eat. According to the feeding behavior of ants, after a worker ant eats the poison bait, as long as it does not die within a short period of time, the poison bait can be Bringing it into the ant nest will cause the death of other individuals. The death time is usually within seven days, but the ant pupae do not eat, so they may survive, making the removal of ants incomplete.

○Juvenile hormone analog poison bait: < /p>

That is, the bait is mixed with juvenile hormone analogues, such as chlorfluazuron, methoxyjuvenile hormone (

methoprene), etc., the hormone concentration is generally 0.6% to 1.5% of the bait weight. Currently, research is underway to add synergists to juvenile hormone analogs to make this method more perfect.

■Life Tips :

Burn egg shells with fire and grind them into powder, then sprinkle them in the corners of walls or near ant nests to kill ants. If there are ants in the closet, you can put some parsley, celery and other flavorful vegetables to drive away the ants. Putting some walnut leaves, tobacco shreds, and Sichuan peppercorns in places where ants often hang out can drive away ants.
