Smoker Fuel

[madasafish]

does any body use no smoke? The only reason I ask is that a few days back when we had a beautiful day I went and put on some pollen patties on top of the frames. Now one lot normally has a right go at me when i do anything but they seemed pretty calm considering i had used no smoke or even syrup spray. I wonder if there is something in the cardboard that iv'e been using any thoughts?

I use no smoke 90% of the time but always have a smoker lit for unforseen emergencies. I cannot tell what bees may do.
