Protect your home from unwanted visitors with the big cheese ultra power rat traps. These traps are performance tested to ensure effective control of rats - just like the traps that professionals use. Simply remove the bait cover, place your chosen bait in the holder and squeeze the trap to set – the traps are guaranteed to kill rats. Note: For best results place the two traps four-five metres apart where rats are active. Heavy infestations may require more traps.
