There is a question that has been asked many times, why don’t swiftlet come to eat insects? Is the insect too big or something else?

After inquiring, they all found the same problem, that is, they all put the insects in the deepest part of the darkness, thinking that by doing this they could trick the swiftlet into flying inside.

Why can’t you put insects in a dark place? Because the swiftlet’s eyes cannot see clearly in places where there is not enough light, this is why swiftlet rely on the “echo location sound” in the swiftlet house, which is the sound we often hear dak dak dak….

I suggest that it be placed in a place where the sun will not directly reach, but in a corner with sufficient light. swiftlet will definitely eat and will attract many swiftlet.
