This disclosure provides a composition comprising a mixture of molecules of Formula (I): {RO-[CH(CH.sub.3)CH.sub.2O)]b[CH.sub.2-CH.sub.2O]a}.sub.mP(=O)(O.sup.−X.sup.+).sub.n(I), wherein R is chosen from linear or branched C.sub.10-C.sub.18 alkyl or alkenyl groups; a is 0 to 50, b is 0-30, and a+b >0; X.sup.+ is potassium, triethanolamine, or H, and m and n are each equal to 1 or 2, such that when m=1 then n=2, and when m=2 then n=1. Moreover, in the mixture some of the molecules have m=1 and n=2 and some of the molecules have m=2 and n=1, wherein the mole ratio of compounds where m=1 to compounds where m=2 is of from 1:1 to 3:1.

It is to provide a method which does not have problem with safety and enables controlling various pests even at a low dosage, and a pest control agent composition and a pest control agent set which are suitable to be used for the method. At least one selected from a compound of formula (I) (wherein, R.sup.1 represents a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group, etc., R.sup.2 represents a hydrogen atom or a C1-6 alkyl group, R.sup.1 and R.sup.2 optionally form a C2-6 alkylene group together, R.sup.3 and R.sup.4 each independently represent a hydrogen atom or a C1-6 alkyl group, R.sup.5 represents a substituted or unsubstituted C1-6 alkyl group or a substituted or unsubstituted C2-6 alkynyl group, Y represents a C1-6 haloalkyl group, X represents a halogeno group, a C1-6 alkyl group, or the like) and a salt thereof is used with an insecticidal or acaricidal active component.
