ABSTRACT:
A method for combating arachnida which comprises applying to arachnida and/or to a habitat thereof an effective pest combating amount of at least one derivative of a 2,3-diaminomaleonitrile of the formula ##STR1## in which X represents hydrogen, halogen, halogenoalkyl or CN, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are defined or different and represent hydrogen, alkyl, alkoxy, halogen, CN, NO.sub.2, dialkylamino, alkoxycarbonyl, alkylthio, alkylthionyl, alkylsulphonyl, OH, SH or NH.sub.2, wherein R.sub.1 and R.sub.b together represent the radical (II) ##STR2## in which Y represents hydrogen, halogen, halogenoalkyl or CN, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are identical or different and represent hydrogen, alkyl, alkoxy, halogen, CN, NO.sub.2, dialkylamino, alkoxycarbonyl, alkylthio, alkylthionyl, alkylsulphonyl, OH, SH or NH.sub.2, and in which R.sub.c and R.sub.d together represent a chemical bond,
or R.sub.a and R.sub.b together represent the radical (II), in which Y, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 possess the meanings given above and in which R.sub.c and R.sub.d in each case represent hydrogen,
or R.sub.a, R.sub.b, R.sub.c and R.sub.d in each case represent hydrogen,
or R.sub.a represents hydrogen and R.sub.b represents the radical (II) in which Y, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 possess the meanings given above and R.sub.c and R.sub.d represent hydrogen.
