Keeping Fruit Flies off Tank Walls! Help please!

[Kurt]

I have seen them climb up the sides even after they have been dusted. The paper towel thing works perfectly. The only problem I have had is, how do I use this method on larger enclosures? I have managed to use it on large critter keepers and a 2.5-gallon tank, but nothing larger so far.

a feeding station as josh suggested is your best bet. Usually a piece of orange on a dish out in the open is enough to keep them occupied until eaten. If they're not eaten within a few hours then you need to feed less flies more often.
