The diols used have both of their hydroxyl groups in non-adjacent positions, and are preferably 2-methyl-2,4-pentanediol, or a 1,3-diol such as 1,3-butane-, 1,3-heptane- or 1,3-nonanediol or preferably 2-ethyl-1,3-hexanediol. These compositions have an ovicidal and acaricidal, and in some cases, pediculicidal activity. The diols are the only active ingredients or are parasiticidal constituents in addition to other pesticides. |
