Insects are members of the group of arthropods, and can be of various species.
There are around 200 million of insects. Their body and specialized extremities split into parts, covered with exoskeleton which can be developed into a shell. They often have wings or antennas. Usually small in size, except for the beetles, which are larger, insects feed on plants, meat or carrion.
They play an essential role in nature, as they feed other species, and prevent them from turning into big plagues. Namely, they eliminate and decompose great percentage of the organic matter, so they are excellent pollinizers of plants which are economically and economically vital.
Yet, there is no doubt that often their occurrence in the home is quite unpleasant. As soon as one sees an insect, he panics, or screams, as none of us wants them near us or our family.
