The present invention provides an excellent ant controller for protecting wooden materials such as trees, board fences, sleepers, etc. and structures such as shrines, temples, houses, outhouses, factories, etc. from termites, and for controlling ants doing harm to crops or humans, which contains as active ingredient thereof a hydrazine derivative represented by general formula (I) [wherein A represents one of formulas (II), (III), (IV), and (V), (wherein Rand Rare H, C-Calkyl, etc.; X is 1 to 5 substituents selected from H, halogen and (halo) C-Calkyl); Ris H or C-Calkyl; Rand Rare H, OH, C-Calkyl, phenylcarbonyl, etc.; Y is 1 to 5 substituents selected from H, halogen, nitro and cyano; Z is halogen, cyano, C-Calkyl, etc.; and W is O or S]; and a method for application of the ant controller.

Ant controllers and method for application thereof

Ectoparasitic insect pest controllers for animals, containing hydrazine derivatives of the general formula (I) as the active ingredient, and methods for application of the same: (I) [wherein A is (II), (III), (IV), (V) (wherein Rand Rare each H, Calkyl, or the like; and X is H, or one to five substituents selected from among halogeno and optionally halogenated Calkyl groups); Ris H or Calkyl; Rand Rare each H, OH, Calkyl, phenylcarbonyl, or the like; Y is H, or one to five substituents selected from among halogeno, nitro, and cyano; Z is halogeno, cyano, Calkyl, or the like; and W is O or S]. The insect pest controllers exert remarkable controlling effects on parasitic insect pests harmful to domestic or pet animals, e.g. fleas, lice, ticks.
