Thrip control in Europe?

[naturalistSean]

After moving to Austria I discovered many of my houseplants have dark black thrips. The Anthuriums seem especially hard hit. As all the plants were in close contact I believe I may have a disaster on my hands. Just today I discovered several thrips on a Paph sukhakuii, and fear other orchids are also impacted. Those sneaky little critters are certainly also hiding where I can't see them.

What to do? Here in Europe many of the chemical insectides that people use in the USA are unavailable.

Have any fellow orchid growers in Europe tried something that worked particularly well? Any particular products or techniques? I'm all ears.
