Q.How To Get Rid of Symphylans

Anonymous added on March 18, 2011 | Answered

My greenhouses are infested with symphylans, and last year I lost 600 tomato plants because of them. What kind of organic formulas or pesticides can I use on them this year? I have decided to keep the tomatoes in big pots, but I know they can travel up into them. I am going to use wood ash below the pots, but I feel I need something more to combat them. Can you help me? They came into my garden in either some organic soil that I bought or some peat moss.

I have heard that Diatomaceous earth will help to get rid of them. I have also read articles about placing pastic over the entire garden area on a sunny day, before any plantings of course, and leaving it there all day long. This is said to heat the soils up and due to them being delicate bodied creatures, the heat kills them.
