Apply using any manual or power sprayer equipped to produce a coarse spray. Add the appropriate volume of FENDONA 1.5 SC to the required volume of clean water and agitate. If a delay occurs between treatments, re-agitate before re-use. Apply at low pressure to just before run-off to surfaces frequented by pests especially cracks and crevices which may act as harbourages, and behind fittings and equipment. Do not allow any run-off to enter watercourses.
