Has anyone thought about, or used, styrofoam for swarm traps? The cost is pretty comparable to wooden construction, maybe a bit cheaper, but at my scale, it is of little consequence. This is assuming I use 2" sheets, but I think 1" sheets will be adequate. These would certainly be lighter than wood construction which might be nice when retrieving from elevated locations. My other swarm traps are essentially 10-frame deeps with secured tops and bottoms, so I'd be making these along the same lines.

Are there reasons to avoid construction of this type?
