ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to ectoparasite controlling agents, and more specifically relates to an excellent ectoparasite controlling agent for animals which is used for regional application methods such as spot-on or pour-on application and a method for controlling ectoparasites of animals.
BACKGROUND OF THE INVENTION
Heretofore, as an application method to control harmful pests that injure domestic animals such as pets and farm animals, particularly ectoparasites such as fleas (Pulicidae), lice (Anoplura) and ticks (Acarina), methods of application recognized as spot-on and pour-on applications have been known, and because these methods of applications have been elementary, they are utilized in the concerning ectoparasite controlling.
However, it was not common to have the active ingredients contained in the ectoparasite controlling agents to be always sufficiently effective.
SUMMARY OF THE INVENTION
The present invention provides an ectoparasite controlling agent for animals having an ability to exert an excellent efficacy against ectoparasites from spot-on or pour-on applications, with the incorporation of a neonicotinoid compound and a glycol or a specific glycol derivative, as well as from the specialized mixing ratio of that incorporation.
More specifically, the present invention is an ectoparasite controlling agent for animals (hereinafter, the present agent(s)) which is a liquid formulation comprising 10 to 95% by weight of a glycol or glycol monoalkyl ether (e.g. C
1-4
alkyl ether) and 0.1 to 20% by weight of the neonicotinoid compound given in the following formula (1), (2) or (3) (herein after, the present compound(s)):
