Fipredronil, methoprene, butylated hydroxyanisole, among which, Fipredronil It kills insects, and methoprene inhibits the development of insect eggs. The last similar antioxidant can make the drug effect long-lasting in the sebaceous glands of pets.

Big favorite: selamectin

Elgin Phylion:

This compound repellent of permethrin, fepredronil, pyriproxyfen, and selamectin combines most of the active ingredients in the above keywords. It has been introduced that pyriproxyfen has similar effects to methoprene in Fulin and is mainly used to kill larvae and eggs

Little Pet Flea Liqing:

Feprenil wants to say that this is "non-pesticide" The label is really ironic...the active ingredient is Predronil, which is a pesticide. However, excluding this point, the main active ingredient is the same as Fulin, but the price is cheaper than Fulin. It is suitable for families with multiple pets at home

Dog Fight 20:

The functions of the first two ingredients of feprenil, selamectin, and lufennuron can be seen in the keywords above. The last one also kills insect eggs and larvae~ This external expelling was still relatively popular in the early years. Yes, but it has been rare in recent years.

Bayer Love Walker (heart scabies feel good):

Imidacloprid and moxidectin. Bayer's exogenous drug can be said to be a breath of fresh air. It contains the ingredients of imidacloprid. After checking, it is the counterpart. Organ insect poison is basically targeted at fleas and ticks

Moxidectin:

The ingredients are similar to selamectin. In addition to targeting external parasites, it is also effective against mites and some internal parasites

New external anthelmintics:

Oral external anthelmintics rely on eating "dried meat" to prevent lice and ticks? Like everyone else, I have many questions and am very curious about this new product launched this year. Because it is a new product, and the relevant company has a patent, there are not many papers available on the principles of the ingredients. The main ones are patent descriptions, which are a bit poor in readability. According to the information provided by the manufacturer, the active ingredient of Nicotine is called Afolana, which is an isoxazoline compound. This ingredient can be formulated as an oral, antiparasitic agent that is effective in treating external parasites such as insects (e.g., fleas, lice, flies) and acarids (e.g., mites and ticks). And it also has relatively good performance against the current drug resistance displayed by parasites.
To summarize some of the characteristics of this new anthelmintic drug: 1. It can be taken orally and is environmentally friendly. 2. It has good palatability. There are no precautions after use, making it easy to manage. 3. For those who have developed drug resistance. Some parasites perform well
