That's always a problematic factor in relation to how humans think, based on profit and cost optimized procedures.
A clean cut forest will destroy room to live for many plants and animals and as well changes the ground structure, nutrients and water household (sun exposure, rain exposure, quick frost and so on) after a few years, while humanity cuts far too many trees and areas down in far too little time, already.
The rat tail of following costs over the next 50+ years is not included into the calculation, unfortunately.. it's just "what to do now?".
As such if the traps work well and are "just" a matter of work time and one-time investment, it's surely one of the best ways to counter invasive species.
Edit: What's up with those images in different threads? Now I have to check.. ?
