Is spraying high chlorine propoxur in the corner harmful to people?

Sometimes yellow ants haunt our house, whether it's on the kitchen floor, on the stove or on the wall. Even the bed and body of the bedridden old man are covered with yellow ants. And the number is so large that it is chilling. I took many measures: using sugar, honey, etc. Draw them out and concentrate on destroying them; Sprinkle camphor powder around the bed; Mobilize everyone to grind by hand, find ant nests, and scald with boiling water in places where ants often appear ... but they all have short-term effects and cannot be carved out of the roots. Desperate, I was introduced and used a medicine, but I didn't expect to solve the problem once. Now I'd like to introduce you.

The name of the medicine is "Yimiqing", which is produced by Guangdong Insect Research Institute. It's not three no products. It has the drug registration number and the manufacturer's address. Effect guarantee: no ants for three years. Each small bag can kill 1-2 ant nests, and each small bag is divided into 3-4 parts and placed on the road where ants pass. Ants will infect each other and die in 2-3 days after taking them back to the hole to eat. The effect is particularly obvious. We only used two packs. After using them, we haven't found another ant. And the price is very cheap, one yuan for a small bag. General fertilizers and pesticides can be bought at the flower market. Because when you use it, put the medicine on the way where ants pass, away from people's food, and we won't touch it easily. There is no danger of poisoning, don't try.

Ants are very 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's ant bait has special effects on this kind of ant)

Use the characteristics of ants to destroy them;

Ants are mostly in the kitchen where there is greasy food. We can use this feature to kill them. Before going to bed at night, move all the food where ants can't go, then put a fat piece of pork on the ground and prepare a thermos of boiling water. The next morning, the ants gathered on the fat meat and ate well. Don't scare the ants away, just scald them to death with boiling water. This will be clean several 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 small yellow house ants, big head ants, stone road social ants, smelly ants, etc., and often nest in roadside, corners and cracks in walls. 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 and blocking the nest. If possible, biological hormones can also be used for prevention and treatment.

Ants belong to Arthropoda, Insecta and Hymenoptera. Although there is only one family (Formicidae), there are more than 360 genera under it, estimated to 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 mountain. The diet of ants is very complicated, and all kinds of animal and plant carcasses and organic residues can become.

With the rapid development of urban construction in China, the living environment of ants has changed greatly and gradually adapted to the urban environment with dense buildings and dense population. They often invade indoor foraging and nesting. Because indoor ants can pollute food, destroy buildings, spread bacteria and bite people, which 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:

Through 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 community ant and smelly ant. Through the analysis of the characteristics of these four ants, although they are far less harmful than cockroaches and flies, they are still hidden dangers at home. Therefore, according to their characteristics of digging holes in the active path and leaving special chemical odor, the following methods can be adopted to remove them:

○ Wet cloth wiping:

If one or more rows of ants are found to be active, they can be wiped off with a wet cloth and drowned in a basin filled with washing powder water;

○ Washing powder ditch barrier:

Because ants will drown as soon as they enter the washing powder, you can protect an area in this way;

A flood:

That is to say, watering the nest 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;

Mixture of fenvalerate silicate powder:

This method is an improvement on the previous method, which can shorten the killing time, but it should avoid inhaling powder or dust 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. Commonly used drugs are as follows:

Spraying more than 90% trichlorfon stock solution 500- 1000 times;

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, as long as a worker ant does not die in a short time, causing other individuals to die, it can bring poison bait into the nest. The time of death is usually within seven days, but the ant pupae may survive without eating, which causes the incomplete extermination of ants.

○ Juvenile hormone analogue bait:

That is to say, 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, synergist is being developed and juvenile hormone analogues are added to make this method more perfect.

■ Life tips:

After the eggshell is ground into powder by burning coke, it can be scattered in the corner or near the ant nest to kill ants. 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.
