Themanfromvolatntis they are vile. I have laid some bags down as suggested but none seen again yet even when it has been extremely heavy rains. It is a very wooded back with a sort of cliff/woods and a farm at the top of the hill so may be coming from there. I have loads of good worms so hopefully they aren't wiping them out. Funny I can lift worms and save them but these things are totally different. When I get some I'll contact the specialists and report back xxx thanks
