Bayer Environmental Rodilon Blocks - 2kg is a highly palatable block with high food grade ingredients, ideal for rat control. The moisture and mould resistance of these blocks makes them ideal bait for both hot and damp conditions. The multiple edges of the blocks are designed specifically to encourage rodent feeding. The green colouring of the block shows in the rodent excrement indicating bait has been taken. Keep out of reach of children and always read the label and product information before use.
