I'm having trouble locating the active ingredient(s) in Indorex.  Please let me know what they are.

Indirect is a flea treatment for the house. Not to put on dogs!
Expert:  Dr. Michael Salkin replied 17 days ago.

Yes, and I need to know the active ingredients in it, please.

Chrysanthemum/ permethrin/pyriproxyfen/ piperonyl/ butoxide
Expert:  Dr. Michael Salkin replied 17 days ago.

Thank you.  Most flea populations are resistant to the pyrethrins in that product and it doesn't contain an insect growth regulator (IGR) which prevents eggs and larvae from developing into adult fleas.  See if you can find Siphotrol area treatment spray (or similar) that contains the IGR methoprene.  The IGRs have revolutionized how we address flea infestation.

Which spot on have you been applying, please?

Customer: replied 17 days ago.
He had Advantage just over 3 weeks ago
Expert:  Dr. Michael Salkin replied 17 days ago.

Once again, many flea populations are now resistant to the imidacloprid in Advantage.  His vet can provide one of the newer isoxazole products such as Bravecto, Nexgard, Credelio, or Simparica to which fleas haven't developed resistance.

Please continue in this conversation if you wish.

I do have a product called Itch Flea. It’s contents are Fipronil and Methoprene?
Expert:  Dr. Michael Salkin replied 17 days ago.

I sound like a broken record but many populations of fleas are also resistant to fipronil.  The methoprene needs to be placed in your premises where eggs and larvae are found - cracks and crevices, mainly.
