There are no remedies....
You can google homemade traps, etc...I've tried a couple but they turn into breeding grounds. Your kitchen literally needs to be void of everything! No fruit, pour bleach down the drain on a regular basis, make sure that tray that collects excess water at the bottom of your fridge is bleached, trash all your house plants, etc...even then, its hard. If you have one...you have them all.
They also travel far...which means, if your neighbour has them there is a good chance you will get them. Sucks not buying bananas anymore
