I have just started gardening and have decided to grow a number of herbs outside the back door. The herbs are in individual pots and all bar the chives are doing really well. Tonight I have spotted that the chives are infested with small greenfly like bugs and flies. Can anyone please reccomend an organic, child friendly, animal friendly insect repellent/killer that will get rid of the infestation? Also could anyone reccomend a organic, etc, snail and slug repellent?
