It is well known that cockroaches can develop into pests in kitchens and other food storages. Less known is that these insects also occur as pests in zoos and greenhouses with tropical crops. Although they show resemblance with beetles, they are not related to them. Cockroaches have overlapping cover shields and do not undergo complete metamorphosis. In a top down view, cockroaches have an egg round shaped body. They are related to grasshoppers and crickets, but lack the jumping hindlegs. Cockroaches are omnivorous and can feed from many plant species and waste. Because of their quick reproduction and stamina (some species can last over a month without food and water), cockroaches can easily develop into pests. Cockroaches move very fast and due to their flat body can hide well in little spaces.
Cockroaches do not like light and are mainly nocturnal. They are often found in groups in warm, dark places. Some species are herbivorous and can cause damage in botanical gardens and zoos. Cockroach feces can cause allergic reactions or asthmatic symptoms.
