Fepredronil

is toxic to crustaceans, ants, termites, beetles, cockroaches, ticks, zooplankton, bees and other insects, so it is more commonly used Used in insecticides, including products that kill many common ants, termites, beetles, cockroaches, ticks and other insects or fleas on pets.
Some research experiments have confirmed that Fipredronil can cause harm to animals, the environment and ecology, and is also a carcinogen. Therefore, Fipredronil has been banned in many countries, including Italy, France, and mainland China; and currently The UK and Australia are also considering banning the use of this particular pesticide.
Fipronil can only be used to kill adult insects. Why can the second generation of Fulin be used to kill insect eggs? Because it contains methoprene. This is a juvenile hormone, which means that insect eggs cannot turn into larvae, and larvae cannot turn into adults, thus achieving the purpose of killing insect eggs.
Our country has stipulated that Fipredronil will be banned from October 1, 2009. Although Fiprenil is very effective in controlling rice stem borer and leaf roller, it is extremely unfriendly to the environment and is highly toxic to fish, shrimps, bees, and silkworms, so the country is still determined to ban it.

Metoprene

is a toxic substance used as a raw material for insecticides and bactericides. Topical insecticides,

It is effective against a variety of insects of the order Lepidoptera, Diptera, Coleoptera, and Homoptera. It is used to control hygiene pests such as mosquitoes and flies, as well as storage period pests such as tobacco borer moths. It is also often used to kill fleas and fleas on pets, and is one of the main ingredients in some pet insecticide sprays.
The pet’s sebaceous glands secrete sebum into the hair surface, forming an oil film that covers the pet’s body. When using this type of insecticide drops, they are usually dropped on the middle part of the spine on the back, and the liquid slowly spreads throughout the body through the sebum. Most bath liquids will wash away the pet's sebum, so the pet cannot be bathed for 3 days before and after using this type of drug.

Selamectin

Selamectin is a member of the avermectin family. Other drugs in the same class include avermectin, ivermectin, doramectin, and eplelenol Bacteria, etc. (yes, those medicines used to treat skin diseases).
The pharmacological mechanism of selamectin is the same as that of other abamectin drugs, that is, by interfering with the chloride ion channel controlled by glutamate in the insect body, it causes the insect body to undergo rapid, lethal and non-spasmodic neuromuscular stimulation. paralysis. Since flukes and tapeworms do not contain chloride ion channels controlled by glutamate, selamectin is ineffective against flukes and tapeworms, and can only kill some nematodes and arthropod surface parasites.
This drug is more effective than other abamectin drugs in treating infections of dogs and cats with fleas (Ctenophora felis and Ctenophora canis), mites, ticks and some internal nematodes (roundworms and hookworms). And it has a very good effect in preventing heartworm infection in dogs and cats.​

Permethrin

The English common name is permethrin, also known as diclofenac, insecticide, and permethrin. Permethrin is a low-toxicity insecticide. It has no irritating effect on the skin, mild irritating effect on the eyes, very little accumulation in the body, and no teratogenic, mutagenic or carcinogenic effects under test conditions. Highly toxic to fish, highly toxic to bees, low toxic to birds.
It has a broad insecticidal spectrum and is easily decomposed and ineffective in alkaline media and soil. It has low toxicity to higher animals and is easily decomposed 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 prevention and control of sanitary pests. Pyrethrins are very commonly used insecticides and are widely used in household insecticide products such as mosquito coils.

pyriproxyfen

pyriproxyfen is a juvenile hormone type chitin synthesis inhibitor with strong ovicide effect
pyriproxyfen is a product of Sumitomo Chemical Company of Japan A recently developed insect growth regulator that can be used to control Homoptera, Thysanoptera, Diptera, and Lepidoptera pests. It has the characteristics of high efficiency, low dosage, long lasting effect, safety for crops, low toxicity to fish, and little impact on the ecological environment.
Pyriproxyfen can deprive insects of the stimulation factors required to lay eggs, inhibit embryonic development and egg hatching, or produce non-viable eggs, thereby effectively controlling and targeting pests. prevention purposes.
