Will bed bugs bite you even in the light at night-time while you're awake/sleeping?

You don't want them either way, kill the bugs! Ahhh

I'm willing to waste electricity to stop being bitten by these bloodsuckers. :P

If you can, get a professional because you need a very thourough cleansing/spraying of your entire building to get rid of these things. Yes, they will bite you with the light on, you cast a shadow. The light just makes it easier for you to watch them eat you.
