I have a couple of Hibiscus in self watering pots that i keep behind the
patio window which is south facing. they had a lot of tiny white flies and
i was told to spray with a mixture of water and dish washing liquid, which i
did. but about three days later they are now back again with a vengence. i
dont know where they have all come from suddenly.

i would prefer not to use chemicals to stop the white fly since i keep the
plants inside. any other suggestions please?
