Do Bed Bugs Come Out When The Lights Are On?

Bed bugs are generally considered to be nocturnal and prefer to forage for a host and take a blood meal during the night. They also will come out in the daytime or at night when lights are on, in order to take a blood meal, especially if there were no human hosts in the structure for a while and they are hungry.

Other Reasons Bed Bugs Are Seen During the Day:

  • Bed bugs will often change their normal nocturnal behavior and feed during the day if the resident(s) work at night and sleep during the daytime.

  • When a bed bug infestation is very large.

Another situation that may cause activity in a lit environment is when bat bugs, which are very similar in appearance to bed bugs, come out during the day or night to consume blood from their preferred hosts, which are bats or birds.

Regardless of the causes, if an occupant sees bed bugs during the day, it is wise to seek the assistance of a professional management professional.
