Only use Sevin if nothing else works. Here is the sheet on the health effects:

I usually try natural methods before using pesticides. In my arsenal of stuff, Sevin is usually my last resort. I am having really good luck with diatomous earth for my plant collection. In the past, I have also gotten rid of some of the pest issues by soaking the pots, as you did. You could buy a few large storage bins and fill them up with water and soak your orchids.
I suggested Sevin as it works when nothing else will. I prefer not to use it when something else will be effective.

As for the option to cool down by hose, I opted for a glass of water, instead.
