Abstract: Fluid compositions for the eradication or control of arthropods comprise a dispersion of at least one siloxane compound as an emulsion in a water continuous phase and having a dispersed particle size in the range 1 to 10 nm, preferably 10 to 50 nm. In a preferred embodiment the siloxane compound or compounds in the dispersed phase comprise from 50 to 99.9 percent by volume of one or more volatile siloxanes with the remainder one or more non-volatile siloxanes. The dispersed phase may have from 0.1 to 15 percent by volume of one or more non-volative siloxanes and from 97.1 to 95.5 percent by volume of one or more volatile siloxanes. The non-volative siloxane is preferably a linear siloxane such as dimethicone or dimethiconol and the volatile siloxane is a cyclic siloxane such as cyclopentasiloxane or cyclomethicone. Arthropods are controlled or eradicated by applying the fluid compositions to a surface which carries, or is believed to carry, arthropods.
