Abstract:
Process for the protection of a building against damage caused by insects comprising the steps of:a) forming a composition which is in solid form, wherein said composition comprises an insecticidally active ingredient, further wherein the amount of the active ingredient in the composition is from about 0.5 to about 80% by weight and the active ingredient has no quick knock down effect and a secondary killing action; b) forming treated and untreated locations along the perimeter of the building by applying an effective amount of said composition to discrete locations around or under said building along the perimeter of the building, wherein the treated locations are the discrete locations along the perimeter of the building where said composition has been applied and the untreated locations are the remaining portions of the perimeter where the composition was not applied; wherein the combination of said treated locations and said untreated locations along the perimeter of the building equal the total perimeter of the building and further wherein said treated locations make up 0.5 to 7.5 meter per 10 meter of the total perimeter of the building, and said active ingredient is an insecticide of the formula (I) in which: R1 is CN or methyl or a halogen atom, R2 is S(0)nR3 or 4,5-dicyanoimidazol 2-yl or haloalkyl, R3 is alkyl or haloalkyl; R4 represents a hydrogen or halogen atom or a member of the group consisting of NR5R6, S(O)mR7, C(O)R7, C(O)Oâ€”R7, alkyl, haloalkyl, OR8 and â€”N&boxH;C(R9)(R10); R5 and R6 together form a divalent alkylene radical which is interrupted by one or two divalent heteroatoms, said divalent heteroatoms being independently selected from the group consisting of oxygen and sulfur; R7 represents an alkyl or haloalkyl radical; R8 represents an alkyl or haloalkyl radical or a hydrogen atom; R9 represents an alkyl radical or a hydrogen atom; R10 represents a phenyl or heteroalkyl group which may optionally be unsubstituted or substituted by one or more halogen atoms or a member of the group consisting of OH, â€”O-alkyl, â€”S-alkyl, cyano, and alkyl; R11 and R12 represent, independently of one another, a hydrogen or halogen atom, or CN or NO2, R13 represents a halogen atom or a haloalkyl, haloalkoxy, S(O)qCF3 or SF5 group, X represents a trivalent nitrogen atom or a Câ€”R12 radical, wherein the other three valences of the carbon atom are part of the aromatic ring, m, n, q, and r represent, independently of one another, an integer equal to 0, 1 or 2, provided that, when R1 is methyl, then either R3 is haloalkyl, R4 is NH2, R11 is Cl, R13 is CF3 and X is N; or R2 is 4,5-dicyanoimidazol 2-yl, R4 is Cl, R11 is Cl, R13 is CF3, and X is &boxH;Câ€”Cl.
