Beyond the annoyance and hygienic problems that pests cause, the most serious way pests harm people and animals are as the carriers of disease. Pests provide transportation and shelter to disease causing organisms called pathogens.

When the pests carrying these pathogens come into contact with our environment, bite people and animals or lay their excrement in our food or surroundings, the germs are transmitted and then passed on through everyday contact. Dengue Fever, Diarrhea, Typhoid, Cholera and Malaria are just some of the diseases transmitted by pests.
