We Have To Discuss Cockroaches
Most humans feel nervous at the sight of a single cockroach. However, this group of insects is one of the most successful animals on Earth, since they have survived 80 million years before the first dinosaurs. They can live in almost all habitats but some prefer to live with humans. If they do live indoors, they can carry pathogens on their bodies and legs. These pathogens can cause food poisoning, diarrhea and wound infections. Some cockroaches, such as the American, German and Oriental cockroaches can leave an unpleasant odor on surfaces they touch. Food items with this odor are considered unfit for human consumption, since the odors usually remain after the food is cooked or processed. Also, cockroach feces and cast skins in infested buildings are important allergen triggers for asthma and respiratory problems, especially in children. For these reasons, cockroaches should be controlled when an infestation exists.
In this booklet are a variety of exercises designed to help educate your students about cockroaches and ways to prevent them from entering buildings.
