Cockroaches are nocturnal creatures, crawling out at night to look for food. Do you know the health risks they can cause to humans? They pick up diseases by lying around in filthy places. Cockroaches will then come into contact with food, utensil and surface.

Cross-contamination occurs if one touches his/her own eyes and mouth after touching items infected by faeces, vomit and saliva and body parts. One can also be infected by eating food and drinking water contaminated by cockroach excrement.

Certain protein in cockroach faeces, saliva, and body parts can trigger allergic reactions and asthma symptoms. They transmit diseases such as E Coli, salmonella enteritis, dysentery and gastroenteritis to humans. The symptoms include fever, nausea, and/or vomiting, diarrhea, muscle and joint pain, chest tightness and shortness of breath.

Newly emerged cockroaches are white. The female produce egg-containing oothecae (egg cases) which contain 14 to 60 eggs. Eggs can hatch within 24 to 48 days and the nymphs emerge. Development from nymph is usually 6 weeks or more. In Singapore, high temperature and high humidity will even shorten the development time.
