Are Cockroaches Attracted to Light?
Picture this: You’ve just wrapped up a long evening of binging your favorite show. You’re walking down the hall to brush your teeth before hitting the sack. You flick on the bathroom light and as your eyes adjust you witness a horrifying sight: cockroaches scattering across your sink and bathtub.
What is it about cockroaches and the nighttime? Are cockroaches attracted to light or repelled by it? And most importantly, how can you help get rid of cockroaches and keep them away?
Almost all cockroaches are nocturnal, which means they’re active only at night. So are cockroaches attracted to light? Nope. Most don’t like it one bit. That’s why they tend to scatter when you walk in a room and flick that switch.
And it’s not just artificial light that cockroaches dislike. They’re not fond of natural light either. Because of this, you’re unlikely to see them during the daytime. If you do notice one during the day, it may be because the roach got crowded out of its home or was forced out of hiding due to a lack of food. In fact, spotting a roach when the sun is still up is a good indicator that you may have an infestation. However, after a while, cockroaches can adapt to their environment and become acclimated to light.
What if you just see one cockroach at night? Does that mean it was just a rogue roach that wandered in? It’s possible, but probably not likely. Cockroaches are aggressive breeders, so their populations can grow quickly. As a general rule of thumb, where there is one cockroach, there are likely many others.
