Flies under our Enviromesh
Posted: Sun Aug 22, 2010 11:12 pm
Since we started using Enviromesh a few years back, things seem a lot better. One thing puzzles me though - under some of our Enviromesh tunnels, there are large numbers of flies (look like normal housefly types, plus whitefly on a few brassicas in the tunnel).
I have lifted the mesh offf a few times to let the flies escape - but more seem to come back! Do these just emerge from the soil, or do I have leaks round the edges?
