Contains: Difethialone 0.0025% Rodilon® Soft Blocks are an extremely palatable formulation due to their high-food grade ingredients, texture and blending of the bait and can be used for the control of rats and mice. This combination gives superior overall performance, especially in very competitive environments where other food sources are available. In its pre-measured 10g sachets Rodilon® Soft Blocks provide the added benefits of reduced operator exposure and ease of handling. The blue colouring of the soft block shows in the rodent excrement indicating bait has been taken. They are ideal for dry environments and difficult to control infestations.
