Pyriproxyfen is a pyridine-based pesticide which is found to be effective against a variety of arthropoda.[1] It was introduced to the US in 1996, to protect cotton crops against whitefly. It has also been found useful for protecting other crops. It is also used as a prevention for fleas on household pets.

Pyriproxyfen is a juvenile hormone analog, preventing larvae from developing into adulthood and thus rendering them unable to reproduce.

In the US, pyriproxyfen is often marketed under the trade name Nylar. In Europe, pyriproxyfen is known under the brand names Cyclio (Virbac) and Exil Flea Free TwinSpot (Emax).
