right.you buy a pint of maggots?yeah?these come out of the fridge in the tackle shop.they are stored in the fridge in a plastic box with about twenty pints of maggots,they all pee-the amonia smell when you don't clean them.by riddling you remove any debris,dying maggots,etc.when you have riddled them clean you can either sprinkle some maize on them or tart them up a little with custard powder,strawberry nesquik,etc.the maize helps to keep the maggots clean by soaking up the amonia and also keeps their skin soft.
go buy a bag of grapes,you may find one which is going bad.leave it in the bag the rest will suffer,would you eat them in this state or nice and fresh and juicy.
it only takes a couple of minutes to clean your maggots,do it,your catch rate will improve with cleaner fresher maggots.
