Rodenticide bait blocks. Suitable for indoor and outdoor use. Each block has a hole in the middle allowing it to be fixed in place. An octagonal shape gives rodents more edges to get their teeth into. Place bait under cover, along walls or rafters and in dark sheltered places where rodents are active. One feed is sufficient to kill a rat or mouse, but they may continue to eat the bait. 1kg pack provides approximately 48 blocks.
