Claim:
A method for controlling harmful arthropods and/or helminths, which comprises applying to these or to the plants or animals, areas or substrates infected by them an arthropodicidally or helminthicidally effective amount of a compound of the formula (I) or an N-oxide or salt thereof, wherein: a) R 1 is phenyl, unsubstituted or mono- or polysubstituted by identical or different radicals selected from the group consisting of halogen, (C 1 –C 4 )-alkyl, (C 1 –C 4 )-haloalkyl, nitro, cyano, (C 1 –C 4 )-alkoxy, (C 1 –C 4 )-haloalkoxy, and phenyl, wherein phenyl is unsubstituted or substituted by one or more radicals selected from the group consisting of halogen, (C 1 –C 4 )-alkyl, (C 1 –C 4 )-alkoxy, (C 1 –C 4 )-haloalkyl, (C 1 –C 4 )-haloalkoxy and (C 1 –C 4 )-alkythio, or two substituents together form a group —O—(CH 2 ) 2 —O—; b) A is a group CR 4 R 5 wherein: R 4 is hydrogen or methyl; and R 5 is hydrogen or (C 1 –C 4 )-alkyl; and c) R 2 and R 3 together with the nitrogen atom to which they are attached, form a piperidine radical which is unsubstituted or mono- or polysubstituted by identical or different substituents selected from the group consisting of (C 1 –C 4 )-alkyl, and (C 1 –C 4 )-haloalkyl.
