Abstract: 1. A method for attracting and controlling insects which comprises offering to said insects for ingestion of an effective amount of a compound having the formula (I):    wherein: R1 is CN or methyl; R2 is -S(OnR3; R3 is alkyl or haloalkyl; R4 is selected from the group comprising a hydrogen atom, a halogen atom, and a radical which may be -NR5R6, -S(O)mR7, alkyl, haloalkyl, -OR8, or -N=C(R9)(R10); R5 and R6 are independently selected from a hydrogen atom, alkyl, haloalkyl, -C(O)alkyl, -S(O)rCF3; or R5 and R6 form together a divalent radical which may be interrupted by one or more heteroatoms; R7 is selected from alkyl or haloalkyl; R8 is selected from alkyl, haloalkyl or the hydrogen atom; R9 is selected from the hydrogen atom and alkyl; R10 selected from phenyl or heteroaryl that is optionally substituted by one or more hydroxy, a halogen atom, -O-alkyl, -S-alkyl, cyano, or alkyl or combinations thereof; R11 and R12 are independently selected from a halogen atom or the hydrogen atom; R13 is selected from a halogen atom, haloalkyl, haloalkoxy, -S(O)qCF3, -SF5; m, n, q, r are independently selected from 0, 1, and 2; X is selected from the element Nitrogen and the radical C-R12; provided that when R1 is methyl, R3 is haloalkyl, R4 is NH2, R11 is Cl, R13 is CF3, and X is N. 2. A method of claim 1, whereby the attracting effect is obtained by the contribution of the insecticidally active compound of formula (I) located among alternative closely situated food or foods also pleasant to the said insects. 3. A method according to any of the foregoing claims wherein the insecticidally active compound is of formula (I) wherein R1 is CN; and/or R3 is haloalkyl; and/or R4 is NH2; and/or R11 and R12 are independently from halogen;and/or R13 is haloalkyl. 4. A method according to any of the foregoing claims wherein the compound of formula (I) is 5-amino-3-cyano-1-(2,6 dichloro-4-trifluoromethyl)phenyl-4-trifluoromethylsulfinylpyrazole.  5. A method according to any of the foregoing claims wherein a population of insects is in a public or private housing area, public or private building, or public or private home. 6. A method for attracting and controlling insects whereby a population of insects is at a locus which is in or near a food storage, preparation, serving or eating area. 7. A method according to any of the foregoing claims wherein attractant is used in the form of a bait, which can be a solid, liquid or gel bait. 8. A method according to any of the foregoing claims wherein the insects to be controlled belong to the families Blatidae or Formacidae. 9. A method for attracting and controlling insects whereby the insects to be controlled are American cockroaches (Periplanipa americana) or German cockroaches (Blatella germanica). 10. A method according to any of the foregoing claims wherein the amount of attractant is from about 0.00001 g to about 20 g of active ingredient of formula (I) per 100 square meters. 11. A method according to any of the foregoing claims wherein the amount of attractant is from about 0.001 g to about 1 g per 100 m2. 12. A method according to any of the foregoing claims wherein the attractant comprises from about 0,0001 to about 15 % w/w of active ingredient of formula (1), preferably from about 0.01 to about 6 % w/w. 13. A method according to any of the foregoing claims wherein the composition ofthe attractant is in the form of a solid or of a liquid. 14. A method according to any of the foregoing claims wherein the attractant is mixed or admixed with a surface-active agent or carrier. 15. A method according to any of the foregoing claims wherein the attractant is mixed or admixed with another pesticide.
