Netizens, please help me find out what this is. I only discovered it when I stayed in the hotel today. My girlfriend was a little scared!

This looks like a fly trap, usually used to catch flying insects. Hotels may place such devices in rooms to prevent insect intrusion.

This fly trap uses light and airflow to attract and capture insects. When an insect is attracted near a machine, it uses airflow to draw the insect into the interior of the machine. The insects are then trapped in a small bag or trap, preventing them from flying around the room.

My girlfriend may find it a little scary or disgusting, but that doesn't mean there will be a lot of insects or other disturbing things in the room. If she's really upset, ask hotel staff to remove the trap or change her room to a room that doesn't have the device.

Hope this answer can help you. If you have any other questions or need further assistance, please let me know.
