Are insecticides effective in getting rid of spiders?

Pesticides are very effective. Most organic synthetic pesticides enter the body of pests and interfere with or destroy normal physiological and biochemical reactions in certain parts. Some ways of entering the body of pests include entering the digestive tract through the mouthparts and penetrating into the blood when feeding, some through the epidermis, and some through the stomata and trachea. The pharmaceuticals entering the body undergo biochemical reactions with various enzyme systems in the pest's body. Act on the nervous system or on intracellular respiratory and metabolic processes. This kind of pesticide utilizes the large adsorption capacity and slow-release effect of nano-silica-based oxides, so that the pesticide's potency can be released from the nano-silica-based oxides for a long time, overcoming the existing technical killing problems. The insecticide has a short residual period of effect, is unstable to light, and is prone to decomposition and failure.

What pesticide is the most effective against spider mites

What pesticide is the most effective against spider mites? ? Which pesticides are effective in killing spider mites? Here are several pesticides for killing spider mites. These pesticides are all highly efficient, low-toxicity, low-residue and environmentally friendly pesticides. First of all, let me explain that this post is not compiled into a post by collecting some words on the Internet. The pesticides in the post are pesticides that I have used and pesticides that I have not used. It was also written after detailed inquiries from local vegetable farmers (there are no local flower farmers). Ekamite is a new generation of acaricide. Its active ingredient, diphenylhydrazine, interferes with the nervous system of harmful mites, causing them to quickly become paralyzed, stop feeding, and eventually die. Unlike other acaricides, it has a reliable control effect on mites that are resistant to other acaricides. It is effective in all life stages of mites, has special effects on spider mites, is safe for crops within the registered dose, and improves the quality of fruits and vegetables. , is a worry-free choice for professional growers who pursue quality. Trade name: Ekamite Common name: 43 biphenyl hydrazine Dosage form: suspension 1. Ekamite is a new type of selective foliar spray acaricide that is effective on all life stages of mites. 2. After the harmful mites come into contact with the agent, they will quickly stop eating, exercising and laying eggs, and will die within 48-72 hours, and the effect will last for a long time. 3. Safe for bees, predatory mites and other beneficial organisms. Within the dosage range, it is safe for crops and can be used in all growth stages of crops. 4. As a brand-new compound, Eika has a reliable control effect on mites that are resistant to other acaricides. At the same time, the drug has a long effect time and can eliminate nymphs and late-hatched mites. Butflufenacet trade name: Jin Manzhi Butflufenfen is a new benzoyl acetonitrile acaricide that has no cross-resistance with existing insecticides. Used for the prevention and control of major mites parasitic on plants in crops and flowers such as fruit trees, vegetables, tea trees, etc. It is effective against both eggs and adults of spider mites, and is more active against nymphal mites. The pest mites died quickly after application. According to experimental comparisons, fenflufenate is superior to spirodiclofen and abamectin in all aspects. The original drug is a milky white solid with no odor. The product is 20 suspensions. It is rapidly metabolized and decomposed in soil and water, making it an environmentally friendly pesticide. Butflufenacet has a low effect on preventing the hatching of red spider eggs, but it has high activity on all growth stages, especially on young mites. It is effective on eggs, adult mites, young mites, and nymphs. . At the same time, it is non-toxic to various plants and is very safe to mammals, aquatic organisms, beneficial organisms, natural enemies and other non-target organisms.

Which pesticide is effective in killing red spider mites?

To kill red spider mites, mineral oil is currently more effective. You can try new pesticides to remove spider mites

Prevention and treatment What pesticide is most effective for spider mites?

Chemical control of red spider mites should use 4000-5000 times of mite risk (800-1000 pounds of water per 100 ml bottle) spray evenly, 40 dicofol emulsifiable concentrate 1000-1500 times, 20 mite net wettability The ideal control effect can be achieved by using 2,000 times of powder as liquid, 2,000 times as liquid of 15-pyrididab EC, and 6,000-8,000 times of 1.8 tetrafen EC.

Agricultural control

(1) Artificial control: scrape the bark of the tree before the overwintering eggs hatch and burn it intensively. After scraping the bark, apply white (lime water) on the trunk to kill most of the overwintering eggs. .

(2) Agricultural prevention and control According to the hatching pattern of red spider overwintering eggs and the habit of first feeding on weeds to reproduce after hatching, plow the ground in early spring to remove weeds on the ground and keep the field clear of overwintering eggs. Weeds cause spider mites to die because they cannot find food.

(3) Physical control can be done by applying non-toxic non-drying sticky glue to the trunk of the tree before the jujube tree sprouts and before the jujube red spider is about to climb the tree to cause damage (about late April). The ring width is about 1 cm. If you apply it again every 2 months, it can prevent the red spider from moving to the tree and cause damage. The effect can reach more than 95%.

(4) There are many types of spider spiders in the field for biological control. According to the survey, they mainly include Chinese lacewings, mite-eating ladybirds and predatory mites. Among them, the Chinese lacewing has a larger population and is more effective against the bay spiders. Spiders have a large amount of prey. Protecting and increasing the number of natural enemies can enhance their control effect on the red spider population.

(5) Chemical control should be sprayed evenly with 4000-5000 times of mite risk (800-1000 pounds of water per 100 ml bottle), 1000-1500 times of 40 dicofol emulsifiable concentrate, 20 mites wettable The ideal control effect can be achieved by using 2,000 times of powder as liquid, 2,000 times of 15-pyrididab EC, 6,000-8,000 times as 1.8 pyridoxin EC.

Flower prevention and control

In the process of cultivating flowers, red spider mites are common destroyers, and those affected include rose, Milan, jasmine, kumquat, crabapple, osmanthus, bergamot, etc. flower. This insect is very small, less than 1 mm, round or oval, orange or reddish brown. Due to its small size, it is difficult to find. Once the damage is discovered, the damage to the flowers is often relatively severe. The way this insect causes damage is by piercing the leaves with its mouthparts to suck the sap, destroying the chlorophyll, causing the leaves to show grayish-yellow spots or patches, and the leaves to become orange, fall off, or even lose their luster.

This insect likes high temperature and dry environment. Therefore, in high temperature and dry climate conditions, it reproduces rapidly and causes serious damage. Insects often gather on the underside of flower leaves and spin silk webs to cause damage. In addition to crawling on its own, the spread of spider mites is also carried by wind, rain and operation.

To prevent and control the damage caused by red spider mites, you should pay attention to observation at ordinary times. When you find abnormal color of leaves, you should carefully check the back of the leaves. If individual leaves are damaged, you can remove the insect leaves; when more leaves occur, spray pesticides as early as possible. Commonly used The pesticides include promethazine, dicofol, dimethoate, anthocyanin, sulfamethoxazole, etc. For home flower gardening, you can prepare a flower sprayer. In 400 ml of water, you can add 4 drops of promethazine, chlormethionine or fentanyl (equivalent to 2000 times of the medicinal solution), and 8 drops of dicofol or dimethoate (equivalent to 2000 times the liquid). Equivalent to 1000 times of the chemical solution), shake well after adding the medicine, and then spray. The spraying must be even and thorough, especially the back of the leaves. When spraying, it is best to move potted flowers outdoors. If spraying indoors, keep away from food and utensils. After each use, pour out the excess liquid and rinse the sprayer with clean water.

Pesticide Can the agent kill centipedes and spiders?

Yes. But I recommend using realgar! Because realgar is for centipedes! In addition, you need to understand the living habits of centipedes! This is the only way to effectively prevent centipedes! The living habits of centipedes.

1. Like to live in groups: Centipedes have the habit of living together in large and small groups. Centipedes in the same group can live in harmony and rarely fight and kill each other. If the habitat is too small and there are too many centipedes, Old centipedes will automatically move away and find another habitat.

2. Centipedes are timid and fearful. If they are slightly frightened, they will stop eating, run away from the nest, or curl up motionless. The female centipede that is laying eggs will immediately stop laying eggs, and the egg-laying female centipede will immediately stop laying eggs. When the centipede is frightened, it will eat the eggs uncharacteristically.

3. Like dark and humid places. Wild centipedes mostly inhabit hillsides, fields, roadsides, places overgrown with weeds, or in firewood piles and gaps between roof tiles. They also often inhabit dark corners such as kitchen corners, and around pig houses and chicken coops. Centipede footprints are also common under the bricks and tiles.

4. Live in the nest during the day and come out to be active at night. The peak of centipede activity is between 8 pm and 12 pm. They usually return to their nests to rest before 4 am. It is difficult to see centipedes after dawn.

The centipede's vision is very poor during the day, and it cannot see clearly things that are slightly farther away. Therefore, it is difficult to find food and defend against enemies. It only relies on a pair of slender tentacles extending forward to find its way. They also rely on their tentacles to hunt for prey at night.

5. Has the habit of licking

Centipedes use the dense villi on the distal segment of the first mandible and the basal protrusions, the brush-like bristles on the back of the distal segment of the second mandible, and The saliva spit out from the mouth is often licked on the tentacles and outside of the legs, and it will also lick its own caves clean

6. Temperature Centipede is a cold-blooded animal, and all its activities are often related to temperature. The optimal temperature for the growth and development of centipedes is 25°C to 32°C. When the temperature is 11°C to 15°C, centipedes’ foraging decreases and they stop mating and laying eggs. When the temperature drops below 10°C, the centipede stops all activities, burrows into the loose soil (or nest soil), curls up, and enters hibernation. However, when the temperature rises to 33°C to 35°C, due to the loss of water in the body, it will All its activities are suspended. If the temperature rises above 36°C and the body loses too much water, the body will dry up and die.

7. Humidity; when the relative humidity of the air is 60 to 70 and the humidity of the nest soil is 10 to 20, all the life activities of the centipede are most active, which means that this is the most suitable humidity for the growth and development of the centipede

The natural enemies of the centipede are Rats, skinks, toads, ants, chickens and birds. Centipedes move slowly when hatching and molting, and they are easily taken advantage of by ant colonies. They can be bitten to death and eaten in just a few hours, so ants must be prevented and controlled in advance.

How to get rid of or kill spiders

1. Spiders often chase cockroaches and other pests. Rooms with many bugs can easily attract spiders. Therefore, the room should be tidy and tidy, and do not throw messy objects everywhere. Haphazard accumulation of objects will create many corners and clean dead spaces, giving pests room to hide and live.

2. In addition to tidying up the room so as not to provide too many hiding places for pests, you must also kill the existing pests living in the room, otherwise these pests will multiply and attract spiders. Pesticides can be sprayed or fumigated to kill them. If the space is large and there are a lot of clutter, you can ask professional pest control personnel to do the pest control, which will be more thorough. Along with killing insects, spiders can often be killed as well.

3. Do not leave doors and windows open for a long time, otherwise spiders and mosquitoes may enter the room. If you really need to open the doors and windows for a long time for ventilation, you can install screens on the doors and windows.

4. Some flowers and trees attract insects, and insects attract spiders. Therefore, when greening and beautifying the living environment, try not to choose flowers and tree species that are easy to attract insects. Try not to place insect-attracting flowers indoors and on balconies. Try not to place flowerbeds and green trees close to doors and windows.

5. Pay attention to tidying up the room at ordinary times. Once cobwebs and spiders are found, they must be driven away or killed in time, and the cobwebs must be destroyed to prevent spiders from multiplying indoors, otherwise spiders may become rampant in the future.

6. For rooms that are prone to attracting insects, don’t think that a thorough pest control sweep will solve the problem once and for all. You should kill or drive away spiders regularly. For daily insect repellent, use household aerosol insecticides or mosquito coils. If you want to drive them away, spray the aerosol insecticide more intensively and leave the doors and windows open; if you want to kill them, spray them more intensely and close the doors and windows tightly and smoke them.

For mosquito-repellent incense, dismantle a whole box of mosquito-repellent incense, put it in a metal container, ignite the whole box with alcohol or fire paper, and then close the doors and windows to kill spiders.

7. If killing can only achieve a short-term effect, and spiders will soon migrate in and cannot be eliminated, long-term preventive measures need to be taken. You can place some realgar in the corners of walls where spiders often build webs, and also place some realgar in the flowers, trees and grass under doors and windows. Spiders don't like realgar, so spiders will not enter the room to make their home. To have both quick repellent and preventive effects, you can spray with realgar wine.

Benefits of Spiders Spiders are both beneficial and harmful to humans, but in terms of their contributions, they are mainly beneficial insects. For example, most of what spiders prey on in farmland are crop pests. At the same time, there are records of spiders being used as medicine in many traditional Chinese medicines. Therefore, protecting and utilizing spiders is of great significance. In particular, protecting rice field spiders has three major benefits: first, it effectively stabilizes the balance of biological populations; second, it reduces chemical pesticide residues in rice and ensures the safety of humans and animals; third, it reduces production costs and increases production and income. Therefore, in the prevention and control of crop diseases and insect pests, it is advocated to use high-efficiency and low-toxic pesticides, carry out biological control, and protect natural enemies, both at the same time. There are many types of spiders with wide distribution and strong adaptability. They can live or build webs on the soil surface, in the soil, on trees, in grass, under rocks, caves, waterside, low-lying areas, bushes, moss, and houses. Inside and outside, or inhabit fresh water (such as water spiders), coastal lakes (such as lake spiders). In short, there are traces of spiders in water, land and air. It is a natural enemy of cockroaches and is more effective than some cockroach medicines at home.
