What is CRRU?
Can I use bait all of the time?
Where can I find more information around controlling rats and mice?
CRRU stand for Campaign for Responsible Rodenticide Use and is the recognised body around the on-going use of rodenticides in the UK.
Can I use bait all the time?
The simple answer is no, rodenticide baits cannot be left in place when there is no activity - if they are to act as a monitor or 'just in case'. Bait can be applied while rats or house mice are active - but you should try to get control of the activity as quickly as possible and then remove all bait.
