## Abstract

The present invention provides an animal ectoparasite-controlling agent containing as an active ingredient a hydrazide compound represented by the formula (1) wherein R3 represents a fluorine atom, a chlorine atom, a bromine atom, a methyl group, an ethyl group or a hydrogen atom, R5 and R6 are the same or different each other and each represents a methyl group or a hydrogen atom, R4 represents a C1-C6 haloalkyl group, which shows excellent controlling effects on animal ectoparasites.

## Claims

### Claim 1

A method for controlling an animal ectoparasite, which comprises applying an effective amount of a hydrazide compound of the formula (1):
wherein R3 represents a fluorine atom, a chlorine atom, a bromine atom, a methyl group, an ethyl group or a hydrogen atom,
R5 and R6 are the same or different from each other and each represents a methyl group or a hydrogen atom, and
R4 represents a C1-C6 haloalkyl group,
to an animal.

### Claim 2 (depends on 1)

The method for controlling an animal ectoparasite according to claim 1, wherein the hydrazide compound is orally administered.

### Claim 3 (depends on 1)

The method for controlling an animal ectoparasite according to claim 1, wherein the hydrazide compound is externally applied to a skin.

### Claim 4 (depends on 3)

The method for controlling an animal ectoparasite according to claim 3, wherein the hydrazide compound is applied by spot-on application or pour-on application.

### Claim 5 (depends on 1, 2, 3, 4)

The method for controlling an animal ectoparasite according to any one of claims 1 to 4, wherein the animal is a dog or a cat.

### Claim 6 (depends on 1, 2, 3, 4)

The method for controlling an animal ectoparasite according to any one of claims 1 to 4, wherein the animal is a cow, a horse, a pig or a sheep.

### Claim 7 (depends on 1)

The method for controlling an animal ectoparasite according to claim 1, wherein the animal ectoparasite is a flea or a tick.
