Bedbugs are known to prefer dark areas for feeding, and they come out to feed at night. So it is best to keep the lights off during the day so you can avoid the bug bites. However, this is not a foolproof solution. You should consider turning the lights on at night if you suspect there may be a bedbug infestation.
Bedbugs are opportunistic and will feed whenever they get the chance. That means they will come out during the day if you haven’t been sleeping for a while. Similarly, if you have a large number of bed bugs in your home, you’ll have to do a thorough inspection of your home to see if they’re active during the day.
The feeding habits of bedbugs are very similar to those of humans. The majority of their feeding occurs during the night when the host is asleep. However, they are known to bite during the day. They do so because their blood flow slows down dramatically at night, which means that they have more time to find a meal.
When the lights are on, bedbugs can move to a different area of the room. If the infestation is too large, they will begin to migrate to a new hiding place.
