One IGR -- fenoxycarb
-- is effective indoors and outdoors to prevent flea infestations from developing.
Logic contains the active ingredient fenoxycarb
, which inhibits development of worker fire ants.

is stable outdoors, whereas methoprene is not.
Some of the most effective compounds are methoprene, hydroprene, kinoprene, fenoxycarb
, pyriproxyfen and precocenes I and II.

Its only active ingredient, fenoxycarb
, is an insect growth regulator (IGR) that breaks fleas' reproductive cycle, preventing eggs and larvae from maturing.
