Dear All,

A friend reminded me that specific  nematodes are an efficient and environmental friendly way to fight sciaridae. The advantage is that they actively move towards the larvae. But the nematodes are relatively fragile and need the right conditions during transport, storage and application to work well. I used them successfully in Germany but do not know if they are available in the USA.

Bye for now
