A mate of mine has a garden rat problem and i offered my Fenn's to him but he looked online (google search) and said they were illegal to use on rats as of 2020 and only can be used for stoats, is this true?

I've recently got hold of a Black Cat trap and was wondering if anyone else was using them?
If so, what are you baiting them with and how are you setting them up, as i can only find American info on ground squirrels?
Thanks

Bought some Victors a while back but never got round to modding them. Had a rat chewing up insulation in the garage this week so it gave me the incentive to get them done.
Fitted a kill bar and a perspex spring spacer to the traps. Fixed them in a box with a couple of screws so they can pivot out to set them. Just set them so will see how i get on.

Neighbour's got piles of soil, rubble, broken slabs etc behind his shed and the rats are loving it. They been coming in under his fence and through into mine behind my shed. Shot maybe a dozen in last 6 months with airgun but just not got the time for that so ordered a couple of mark4's. And with the helpful posts of you gents on here.. First one yesterday.
 

 
 
 
 
 
 

This is OUELL RM trap.  Used for muskrats...nethertheless, it has proven itself highly effective in the dispatch of grey squirrels.  These photo are of the RM set with the safety on.  It is shown without it's artificial cedar tunnel.
