The bright yellow sticky traps that are intended for white flies are 
extremely attractive to fungus gnats.  You could probably just stick
a piece onto the underside of your hood.  They stay sticky a long time.
You can buy this stuff at garden centres.  The particular shade of yellow
used is apparently quite important.  I've tried faking it with various
kinds of yellow plastic with unimpressive results.
