I'm wondering why the fungus gnats show up every February and where they're coming from.  I guess it's possible that the feverfew is suppressing the gnat population but one key question is if it's effecting their reproduction or if you have some other cultural change that's effecting the gnat population.  Are you watering with something different?  Is the pollen reaching the soil?  The gnats lay their eggs in the soil and that's where the larvae develop.  Have you seen any signs of the tiny, nearly clear larvae at the soil surface?  Do you use yellow sticky traps to monitor?  Are you certain they are fungus gnats and not shore flies?
