They smell very strong, which is a good thing. I went with Clove and Pumpkin Spice scents. Rot used big piles of cones in cauldrons to make this awesome smoke (and smell!) effect. I've opted for sticks, which I'm going to try sticking in pumpkins, just to give a little spicy scent to the haunt. We'll see how it goes!
