I often have cockroaches or bugs in my house and need to use pesticides to clean them up. Mosquitoes have been a nuisance for a long time. In order to kill mosquitoes and cockroaches, people often spray pesticides in hidden places such as corners and kitchens.RAMBO insect killer supplier Are these pesticides for mosquitoes and cockroaches harmful to the human body? Can pesticides kill bedbugs?

Introduction of Insecticides

Aerosol insecticides are insecticides that are sprayed in a mist when used in pressure-resistant containers with valves that package the raw materials of the insecticide and the pellets together. It was first successfully developed in 1982 in China. Aerosol insecticides have good insecticidal effect, easy to carry, use, storage, fast effect, accuracy and high characteristics.

Classification of insecticides

Dichlorvos: It is a kind of high efficient and low toxicity organophosphorus agent, with strong poisoning, fumigation and gastric toxicity, wide range of insecticides, fast speed, short duration of efficacy, and small residual toxicity. Do not mix with alkaline reagents. Dichlorvos emulsifiable concentrate is volatile, so be sure to cover the bottle after taking the medicine. When the concentration is high, it is easy to cause damage to cherry blossoms and plum blossoms.

Oxidized Rogaine: It has poisoning effects of poisoning by contact, internal suction and stomach, and it can control many pests with stinging and chewing mouthparts, but the acute gastric toxicity to human and animals is relatively large. It can be used to control mealybugs, aphids, whiteflies, vermilion leaf mites, green blind bugs, thistle, leafhoppers, citrus leaf moths and other pests by spraying 40% emulsifiable concentrate 1000-1500 times.VITFE insect killer manufacturer It should not be mixed with alkaline chemicals.

Roca: A high efficient and low toxicity broad-spectrum organophosphorus chemical insecticide with contact, inhalation and stomach toxicity, generally use 40% EC 1000-1500 times or 60% WP 3000-5000 times to spray aphids, red spiders, leaf cicadas, leaf moths, whiteflies and other pests, but also can be used with 1 gram of the drug plus 20-40 grams of water, 400-500 grams of the coating agent, to control the underground pests of mayflies and so on. Plums and cherry blossoms are sensitive to Rogaine and should be used with caution. Do not mix with alkaline reagents.

Malathion: It has poisoning effects of touch, stomach and fumigation, with high efficacy, wide range of insecticide, residual period of about one week, low toxicity to humans and animals, and is relatively safe. Commonly used 50% emulsifiable concentrate 1000-2000 times liquid spray to control aphids, red spiders, leafhoppers, thistle, mealybugs and other pests. Malathion is less stable, its efficacy time is not too long, and it can not be mixed with alkaline or strong acidic pesticides.

Fenthion, also known as zero, is a highly toxic insecticide. It has strong contact, gastric toxicity and fumigation effects, and is effective in killing eggs, but has no endosorption conduction effect. Fenthion is a yellow-brown oily liquid, unstable to ultraviolet light and air. Due to the action of sunlight and enzymes, it decomposes faster inside and outside living plants. It has a long residual time in inanimate objects, with a residual period of 4-5 days in leaves.Chinese SLEEP COOL Insecticide spray It is also highly lethal to bees and natural enemies. Commonly used concentration is 50% EC 1000-1500 times solution. It is very effective in the control of red date deficiency and red date stick insects.

Parathion Methyl: also known as Methyl 1605, brown oily liquid, insoluble in water, soluble in ethanol and acetone. Stabilized in neutral and acidic media, rapidly decomposed when encountering alkaline substances. It has poisoning effects of touch and stomach, and has certain vaporizing effect. The residual period of methyl parathion on green leaves is 12-36 hours, and it can remain on inanimate objects for several days. The main control targets are date palm stick insect, date palm geometrid and so on.

Phoxim: light yellow oily liquid, stable in medium and acidic environment, easy to decompose in alkali. It can be degraded faster in sunlight. It can be degraded more slowly under dark social conditions. The residual period is 2--3 days. Phoxim has strong poisoning effects on bees. It can kill and fumigate bees. It is a highly efficient pesticide with low toxicity and low residue. It has the best killing effect on date stick insects, and also has special effect on Lepidoptera larvae, mealy bugs, fruit flies and the main pests in warehouses. Commonly used drug concentration is 50% phoxim 1000 - 1500 times.

Monocrotophos: strong contact action, both systemic and gastric toxicity, wide range of killing, efficacy period of about a week, toxicity to humans and animals. 2000-4000 times spraying 50% EC to control aphids, red spiders, leafhoppers, thistle, green bugs and other pests, can not be mixed with alkaline insecticides.

Hazards of insecticides

1. Most of the sprayed drugs are retention type. The toxic substance first floats in the air, and then falls in every corner of the room, including food. When people enter the room, these toxic substances not only kill pests, but also violate the health of people and animals.

2. Chemical pesticides are toxic to humans and can paralyze the oral mucous membranes of the brain and central nervous system. Elderly people and children have lower resistance and therefore have a very high incidence of the disease.

3. The toxic substances of chemical pesticides are very harmful to human sperm and affect the health of the next generation.

4. The toxic ingredients of chemical synthetic pesticides, due to the existence of some unfavorable degradation problems, so on the survival and development of our human society, environmental factors also have a great impact. According to the experiment conducted by Zhejiang People's University in October 2001, after spraying cockroaches with commercially available insecticides, the cockroaches would come back to life after a short period of 4-6 hours, and what was not seen at that time was only a pseudo-death phenomenon. As shown in the news, 7 out of 9 cockroaches that fell to the ground came back to life on the next day. The resistance of cockroaches has increased by tens or even hundreds of times in China. Therefore, the toxicity of chemical insecticides must be increased continuously.
