Cockroaches directly affect the normal functioning of the ecosystem. No matter how useless we consider cockroaches, their contribution to nature is actually quite large. If cockroaches disappear, then birds and rats will not be able to feed on them, which will lead to a decrease in their population throughout the world. Yes, of course, these animals will not completely disappear, as they can feed on grass, caterpillars and other insects. You can not say about some species of wasps that are most likely extinct if the cockroaches became extinct. In addition, cockroaches enrich the earth with nitrogen, which has a beneficial effect on the growth and development of plants, and if they do not, then a decrease in plants will again lead to a decrease in the population of those animals that feed on them. Therefore, we just need to put up with cockroaches!
