A method of controlling harmful ticks which have acquired resistance to 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile at a locus which comprises applying to the locus an effective amount of composition killing ticks comprising as active ingredients 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)- 5-(trifluoromethyl)pyrrole-3-carbonitrile and a pyrethroid insecticidal ingredient(s). 5. A method according to claim 4 wherein the composition killing ticks comprises 0.1-5 weight parts of a pyrethroid insecticidal ingredient(s) to 1 weight past of 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile. 6. A method according to claims 4 and 5 wherein the pyrethroid insecticidal ingredient(s) are selected from the group consisting of the following (1)-(9): (1) Extracted ingredient of pyrethrum containing (Z)-(S)-2-methyl-4-oxo- 3-(penta-2,4-dienyl)- cyclopent-2-enyl (IR)-trans-2,2-dimethyl-3-(2-methyl-prop- 1-enyl)cyclopropanecarboxylate (Pyrethrin I) and (Z)-(S)-2-methyl-4-oxo-3-(penta-2,4-dienyl)cyclopent-2-enyl (E)-(IR)-trans-3-(2-methoxycarbonylprop-1-enyl)- 2,2-dimethylcyclopropanecarboxylate (Pyrethrin II); (2) 2-(4-ethoxyphenyl)-2-methylpropyl 3-phenoxybenzyl ether (Ethofenprox); (3) (RS)-α-cyano-3-phenoxybenzyl (Z)-(1RS, 3RS)-3-(2-chloro-3,3,3-trifluoropropenyl)-2,2-dimethylcyclopropanecarboxylate (Cyhalothrin); (4) (RS)-α-cyano-4-fluoro-3-phenoxybenzyl (1RS, 3RS, 1RS, 3SR)-3-(2,2-dichlorovinyl)-2,2-dimethyl-cyclopropanecarboxylate (Cyfluthrin); (5) (RS)-α-cyano-3-phenoxybenzyl (1RS, 3RS, 1RS, 3RS)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane- carboxylate (Cypermethrin); (6) 2-methylbiphenyl-3-ylmethyl (Z)-(1RS, 3RS)-3-(2-chloro-3,3,3-trifluoroprop- 1-enyl)-2,2-dimethylcyclopropanecarboxylate (Bifenthrin); (7) (RS)-α-cyano-3-phenoxybenzyl 2,2,3,3- tetramethylcyclopropanecarboxylate (Fenpropathrin); (8) (RS)-α-cyano-3-phenoxybenzyl N-(2-chloro-α,α,α-trifluoro-p-tolyl)-D-valinate (Fluvalinate); and (9) 3-phenoxybenzyl (1RS, 3RS, 1RS, 3RS)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (Permethrin).
