Deterring Mosquito's, Fly's, Nats in heavily bushed Shrubbed Garden
I have an area at the bottom of my garden fully surrounded by 6ft plus bushes and shrubs, but these last few years my relations and I have been bitten galore by nats & mosquito's. We have a pond at the top of the garden where we are also bitten. Its put one member of my family from going out into the garden. I have tried Lavender but I'm not sure it doing the trick. My lower garden has Lavatera, Conifers, some Roses, Rock Roses, Heather, Hebe, Broom, Buddleia, Bay Leaf among other bushes. What could I plant or do for that matter that will reduce if not deterring these insects? Many Thanks.
