Do Bed Bugs Come Out When the Lights Are On?
WouterA sign of a bed bug infestation can be itchy skin, and you may notice “peppering,” or black spots of fecal matter. These can appear in the seams of your mattress. Often, bed bugs shed their skin up to five times before they become fully grown. You will be able to recognize them after a few sightings, but if you are unsure, you should seek medical advice.
The answer to the question “Do bed bugs come out when the lights are on?” may surprise you. Normally, bedbugs are nocturnal, leaving their harborages during the night to feed. But in some cases, they will come out during the daytime when they are hungry. Hence, it is not wise to leave the lights on during the night, because this will only encourage bedbugs to come out during the daytime hours.
If you notice a few bites on your skin, the bedbugs may have been hiding in your bedroom during the day. It’s rare for these bugs to come out during the day, because they are opportunistic feeders. Nonetheless, they do appear during the day when they are looking for a host.
In some cases, the bedbugs may initially believe that it’s daytime when the lights are on, but they’ll eventually realize that this is a trick and scurry away. You can test this theory by lying in bed with the lights off and then turning them on. The light should make the bugs scurry out of your bed and hide from your sight.
