Monitoring blocks are for pest control use in the food manufacturing industry when poisons may not be used.  This method will detect if there is rodent activity without the permanent use of poisons.

Supa-Kill Non-Toxic Monitoring Block

Should rodent activity be found with the use of monitoring blocks, then placement of poison blocks or other mechanical methods should be used for a brief time and documentation should be changed stating so.

The monitoring blocks are compressed cereals with an attractant mixed in. there is a hole through the middle to secure the block to a bait station. This allows the rodent to feed from the block without taking it away.
