Trapping water frogs

Hi my name is Werner I am from South Africa, and a very enthusiastic angler (freshwater). I wonder if anyone can assist me with regard to a cheap and simple way to  make  my own  frog trap to trap water frogs, as I use these frogs for bait when targeting catfish.
Any ideas and assistance will be appreciated.
