These black plastic disposable traps are branded "Beetle Blaster". They are designed to be disposable since they are made of quite soft  flexible plastic which makes them very difficult to clean and re-use. The are also very effective when used correctly but because they are disposable they are probably not as economical as the metal traps, at least in the long term.
