Pest detecting and trapping devices, including insect-trapping sheets defining adhesive surfaces, light sources supported proximate the adhesive surfaces, and power sources configured to deliver power to the light sources. In some examples, pest detecting and trapping devices may be particularly tailored to monitor pest activity within shipping containers during transit. Additionally, this disclosure discusses methods of detecting and trapping pests in shipping containers by providing pest detecting and trapping devices, placing the pest detecting and trapping devices within the shipping containers, and manipulating the pest detecting and trapping devices into closed configurations after passages of time.
