Sounds like this is a nasty creature for sure. We don't have this insect up in B.C. (Yet). There was an isolated incidence in Alberta, but I think that the problem was eradicated pretty quickly. I read ona forum post that a fellow in a southern state university was doing research on this SHB using two types of nematodes and that information might be published this spring. That is all that I know. We use predatory nematodes of one species in our gardens here in the late spring. We purchase these little critters from a local seed site, Westcoast Seeds, to be specific and they come in a little sponge that one mixes with water, sprays the ground with the concoction during the evening or on a rainy day. If it is not a rainy day, it is recommended to water these nematodes into the ground thoroughly. I do know that they do wonders to combat many different types of insects, of course particularly the underground cut worms, maggots, etc., I believe they even help to keep at bay the ones above ground, like the Imported Cabbage Moth, which is a huge issue around here with the leafy vegies and others. These organisms occur naturally in the soil, but when they are introduced in huge numbers they work miracles. I have my doubts that the nematodes woudl work against the SHB, from what I am hearing, because the SHB is so transient, I read that they can fly 50 miles, Yikes!!! I wonder how far they could fly if they took a break every 50 miles or so (LOL). Anyways we are fortunate that we don't have this creepy nasty slimy thing up here and I am grateful for that. Cindi
