I think they are working

It’s hard to tell but I think these help. I have something that devours the roots of my vegetable garden every spring. I’ve been applying nematodes each year, the problem has not gone away but maybe it’s less intense? Or maybe it’s just the heat and dryness that helps.

Watching and waiting

So far so good. Watching for any signs of infestation. We’ know in about another week or so.

Nematodes Making Progress

I’ve made four applications in my 200 square feet garden over two years. I am discovering significantly fewer wire worms as time goes on. The few I find are smaller and seem less robust. They are still being found in the surrounding area I don’t control. My crops are doing better. I think it’s going to difficult to completely control them. It seems in the Portland climate the nematodes should be able to survive and multiply year to year but I don’t know for sure.
