Emulsifiable compositions comprise: (A) a first component comprising more than 25 wt% of an aromatic hydrocarbon soluble compound, e.g., a pyrethroid, and (B) a second component comprising 25 to less than 75 wt% of at least one of: (1) a propylene glycol methyl ether propionate, (2) an ethylene glycol n-butyl ether benzoate, (3) dipropylene glycol diacetate, and (4) a glycol alkyl ether ester having a polar Hansen parameter from 3.5 to 5.6 (J/cc)1/2 and a hydrogen bonding Hansen parameter from 8 to 9.2 (J/cc)1/2. embodiment the compositions are free of an aromatic hydrocarbon solvent.
