There are multiple advantages to letting pot tops dry out. For 
the gnats though, I use a BT product (Bacillis thurgensis may 
be spelled wrong). Comes in small bottles at many retail garden 
stores. Takes time to build up the living anti-gnat population of 
BT critters. Then they attack the larva under the soil. Works 
great for me. Just dilute and pour on soil. Water it in a bit. Once 
they are established, just treat new soil or pots you bring in if 
you want them to be protected. The stuff probably kills all 
butterfly and moth larva. I'd be careful not to get it on the leaves 
of plants eaten by larva you love. May not be active outside the 
soil though.
 Happy "Spring" for those on the North part o' the planet, KellyO
