Bedbugs are successful at hiding during daylight hours due to their aversion to light and their flattened bodies.
Step-by-step explanation:
Bedbugs are successful at hiding during daylight hours due to their aversion to light and their flattened bodies. They have evolved to avoid light because it exposes them to predators and increases their chances of being detected. Additionally, their flat bodies allow them to squeeze into tight spaces, such as cracks and crevices, where they can easily hide from sight.
