they do in theory but there are so many of them now that it is an augean stables type task and many land owners have pretty much given up trying , hence the EA trapping licence scheme. The disease (well fungus) they carry is lethal to our native crays which is the principal reason for their reduction in numbers.

signals also do significant damage to river banks etc by creating honeycomb like burrows which lead to bank collapse and errosion.
