Scrap tires are ideal mosquito incubators as they absorb heat and trap rainwater, leaf litter and microorganisms. These factors promote the growth of mosquito larvae. Consequently tire piles can cause mosquito-borne diseases like Encephalitis, Malaria, Dengue Fever, Yellow Fever, Equine Encephalitis and St. Louis Encephalitis. Spraying the piles with insecticides is environmentally hazardous and costly. It is almost impossible to reach the depths in the tire piles where the mosquitoes breed. Dengue Fever is not uncommon and globally, it is the most deadly mosquito-borne disease known to Mankind. A 1995 International Health Organization study of Dengue Fever found that over 3,200 people contracted the disease. On average 5% of patients with Dengue Fever die and the victims are mostly children under 15 years old.
