The Big Cheese Rat Trap is very easy to use / set and easy to remove rodent when job is done (no handling). Buying a pair in a pack is definately far better value then the single packs. The quality is perfectly good enough to do the job repeatedly. I would recommend.
We must have the most cunning rats in Britain, the rats just went around them. We hid them in the taller grass but they didn't fall for it. Maybe better with mice, but we have a cat for that.
I hate killing anything but we had a problem with very healthy rats coming into our garden! I couldn't use bait as I have pets. These traps are extremely powerful so watch your fingers. The supplied bait didn't attract anything so I used nutella which worked wonders. Make sure you cover the traps with wire, they will catch anything!
