Do cockroaches like light
There are no native light-hating cockroaches
There are not any cockroach species native to North America that prefer dark environments. African and Asian species are common household pests, but they are no more “native” to the United States than we are. The species most commonly found in American households is the German cockroach, which is actually native to tropical regions of Southeast Asia. All of these cockroach species are highly adaptable and can survive in both light and dark environments. The choice has more to do with the availability of food and safety from predators. A few species of cockroaches native to the tropical rainforests of South America prefer to spend their entire lives in complete darkness. These species spend more time eating fungi, including decaying leaves, tree bark, and other forest litter, than they do on your kitchen floor.
Cockroaches can run really fast in the dark
Most cockroaches prefer to run away when they see light, while others make a beeline for the darker corners of the room. In either case, their reactions are triggered by the light itself, rather than any sudden increase in temperature. There are species of cockroaches that prefer light, though. These are the ones that live in the desert, where sand, grit, and warm temperatures are the norm. These light-loving cockroaches are equipped with special light-sensitive cells in their bodies that measure the amount of light present. This helps them to identify objects nearby and avoid collisions in the dark. In fact, many desert cockroaches are so light-dependent that they become trapped under rocks and logs, where light rarely reaches.
Light is not a cockroach’s only defense
A perfectly dark environment is a safe environment for cockroaches, but not all of them can survive in the dark. Some species are simply not bright enough to see their own feet, while others are just too slow to run away from predators. Light pollution may help keep these species alive by keeping them hidden, but it also attracts hungry predators and parasites. Insects in general have a hard time navigating in areas with a lot of light pollution, which is why you may see roaches, crickets, and crickets all huddling together in a dark corner of your kitchen. Cockroaches are particularly susceptible to light, but they also have a potent chemical defense system in the form of pheromones. These chemical defense systems are primarily used to mark territory and attract mates, but they can also be used as an insect repellent. In combination with light pollution, these pheromones are supposed to keep roaches safe and hidden from predators.
Dark spots are roach babysitting stations
Dark corners and crannies are where you’ll usually find roaches, but a few species prefer the light. As we mentioned above, some species of cockroach native to the rainforest prefer to live in the light. There, they nest in the crooks of plants and palm trees and eat mostly fungi and decaying leaves. But how do they avoid being eaten by predators? The answer is simple. They hide in the darkest nooks they can find. They’re safe as long as they keep their lights turned off, but they can turn them on whenever they need to eat, mate, or escape a predator. These light-loving roaches, along with a few species of cockroaches that prefer the light in North America, can turn their lights on and off by activating and deactivating special cells in their bodies.
The presence of light makes roaches hungry
Cockroaches are essentially scavengers that eat whatever they can find, including decaying wood, wood mulch, and human food and waste. As long as it’s not too far gone, it’s fair game for a roach. While light does not actually make a roach hungry, it does make them more likely to seek out food. Not only does it help them find and eat food, but it also keeps them safe from predators. This is because cockroaches are nocturnal, which means they are most active at night. When roaches are near light, they are more likely to move towards it and away from their predators.
So, what do cockroaches eat?
If a roach has the option, it will almost always choose your food over its natural diet. It’s important to note that roaches will eat just about anything, including other roaches if they are hungry enough. Food is food, and cockroaches have been around long enough to eat just about everything. While most roaches prefer to eat decaying wood, wood mulch, and human food and waste, a few species in tropical rainforests prefer to eat mostly fungi. Of course, there are also a few species that prefer to eat light. No matter what they’re eating, though, roaches are capable of consuming almost twice their body weight in a single day.
Conclusion
Cockroaches are definitely not the cutest insects, but they are also not entirely to blame for the abhorrence we feel towards them. They are actually very interesting and complex organisms that have been around since before the dinosaurs. If you are ever unfortunate enough to have cockroaches in your home, don’t worry! They can be easily removed with the right tools and a little persistence. Just remember that cockroaches are more afraid of you than you are of them, and they aren’t looking for a fight.
