I'm with you on removing food source, think they get drawn to compost bins which compost all kitchen waste they can smell it but can't get in. Other thing is bird feeders ( didn't want to stop feeding with this dry weather as their very hungry ) very little waste as the Woodies clean most up. I quite like catching them up. Also I have a circle of chain link for grass cutting which i've left over the years because it full of slow worms. When it gets wet and cold sometime they move in there, if i see signs soon sort them there, even fired the ferret in before now. Thanks for advice on the trap,
