I did a side-by-side test of the effectiveness of the Rescue Disposable Fly Trap and a Chinese knock-off. The difference is almost shocking: the Chinese fly traps captured just a tiny fraction of what the Rescue traps did. This video shows the results after one week. I have both versions of these traps placed all around the property, and the results are the same: the Chinese traps capture few flies, while the Rescue traps end up being packed solid with flies. It could be 100 to one, or more, in the catch effectiveness. There is no question that the Rescue fly trap’s attractant is far superior to that provided by the Chinese company.
Plus, the Rescue traps have the attractant built into the unit, so you just add water, and the plastic holding the attractant dissolves. You have to cut open the Chinese trap’s attractant and pour it in, and you invariably get it on your hands.
What matters most is how well the trap works, and the Rescue has the Chinese knock-off beat by a factor that is probably 100 times.
