Bro...I'm not sure whethehr cover will really helps, as the flies will just be trap at the net and die off.
One of the main cause for the flies is dirty filter/water.
If you have clean water, they will be minimise. Also the flow rate in filter is important. only with "dead water", then they can spawn and hatch inside. otherwise, any egg layed will be flow on, and died off before hatching.
my 0.02 cents.
