We burn cinnamon roots (is that what they are called?) in small bowls to avoid this problem during summer. Might be worth giving a shot. The smoke coming out of the bow, if it doesn't fly away immediately, will hide the pheromones. It also help us reduce mosquitos as well, but I don't know why that works.

The pieces of dried curled cinnamon bark we buy for cooking are usually called cinnamon sticks, of that's what you mean by the "roots".

Cinnamon spice is actually a bark. Unless you're literally referring to the bark in which ignore this.
