Fipronil is toxic to crustaceans, ants, termites, beetles, cockroaches, lice, zooplankton, and bees, so it is mostly used as an insecticide to kill many common insects such as ants, termites, beetles, cockroaches, lice, or flea products for pets. Some research experiments have confirmed that fipronil can bring harm to animals, environmental ecology, and is also a carcinogenic substance, so fipronil has been banned by many countries, including Italy, France, mainland China; and currently the UK and Australia are also considering banning the use of this special pesticide. Fipronil can only be used to kill adult insects, why can the second generation of Foleyne kill eggs, because he added methoprene (methoprene). This is a kind of juvenile hormone, that is to say, the eggs have no way to become larvae, larvae have no way to become adults, to kill eggs. China banned fipronil from October 1, 2009. Although fipronil is very effective in controlling rice borer and leaf roller, but it is extremely unfriendly to the environment, highly toxic to fish, shrimp, bees and silkworm, so the country is still determined to ban it. Methoprene is a toxic substance used as a raw material for insecticides and sterilizers. Topical insecticide, effective for Lepidoptera, Diptera, Coleoptera, Homoptera a variety of insects, used to control mosquitoes, flies and other health pests, and tobacco borer moths and other storage pests. It is also used to control lice and fleas in pets, such as one of the main ingredients of some pet insecticide sprays. The sebaceous glands of pets secrete sebum to the surface of the hair, forming an oil film that wraps the entire body of the pet. When using this type of insecticide drops are usually applied to the middle spine of the back and the solution is slowly spread throughout the body through the sebum. Most baths will wash the sebum off the pet, so the pet should not be bathed for 3 days before and after the use of this type of medication. Seramycin Seramycin is a member of the avermectin family. Other drugs in the same class include avermectin, ivermectin, doramectin, eprinomectin, etc. (yes, the ones for skin diseases). The pharmacological mechanism of action of selamectin is the same as that of other avermectins, i.e., it interferes with the glutamate-controlled chloride channels of the worm to cause rapid, lethal and non-spastic neuromuscular paralysis of the worm. Since trematodes and cestodes do not contain glutamate-controlled chloride channels, selamectin is ineffective against trematodes and cestodes, and is only effective against some nematodes and arthropod-like surface parasites. It is more effective than other avermectin drugs in the treatment of fleas (Ctenopharyngodon and Ctenopharyngodon), mites, ticks and some internal nematodes (Ascaris and Hookworm) in dogs and cats, and it is very effective in the prevention of heartworm infections in dogs and cats. Permethrin is also known as permethrin, diclofenac, deltamethrin, and benzothrin. Permethrin is a low toxicity pesticide. It has no irritating effect on the skin and mild irritating effect on the eyes. It has little accumulation in the body and is not teratogenic, mutagenic or carcinogenic under test conditions. It is highly toxic to fish, highly toxic to bees and low toxic to birds. It has a wide insecticidal spectrum and is easy to decompose and fail in alkaline medium and soil. Low toxicity to higher animals, easy to decompose under sunlight. It can be used to control a variety of pests on cotton, vegetables, tea and fruit trees, and is especially suitable for the control of sanitary pests. Permethrin is a very commonly used insecticide, and has wide application in mosquito coils and other household insecticide products. Mosquito ether Mosquito ether is a kind of juvenile hormone type of chitin synthesis inhibitor, with a strong egg-killing effect Mosquito ether is a kind of insect growth regulator recently developed by Sumitomo Chemical Company in Japan, which can be used for dry control of Homoptera, Compositae, Diptera, Lepidoptera pests. It has the characteristics of high efficiency, low dosage, long duration, safety to crops, low toxicity to fish, and low impact on the ecological environment. As mosquitoes are deprived of the stimulating factors required for egg laying, it inhibits embryonic development and egg hatching, or generates eggs with no vitality, thus effectively controlling and achieving the purpose of pest control.
