Cockroaches are among the most hated animals and there are plenty of reasons for that. Beyond their visual appearance, they’re transmitters of bacteria, they cause allergies, and leave feces in the places they pass through. However, it’s estimated that only 20 species of the more than 3,500 that exist are those that annoy human beings.

Far from cities, cockroaches are a source of food for small mammals, birds and reptiles. In addition, they consume decomposing matter and the excrement they leave is full of nitrogen, an essential element for plant growth. So without these insects, an imbalance in the ecosystem would be created, both in the animal and plant world.
