yes agree with dovescot, I was getting clouns in my back garden, so I used an old army one. with trip wires, very thin wire about 4 inch from the ground zig zagged, I also put some about 4ft high they were nasty, anyway I made enquiries and was told if anybody got hurt i would be charged, the old a mans house is his castle doesnt apply now, you should ask them in for a cuppa and have a talk with them,and say please dont do damage to my property
