Background: The negligence of health education and promotion has contributed to increase in morbidity and mortality of malaria among children. Method: This study was carried out in selected secondary schools in Akure, South-western Nigeria to assess the level of awareness, knowledge and perceptive of the use of treated mosquito nets among children of age group 9 and 17 years. 200 pieces of questionnaires were distributed randomly to the respondents. Results and Discussion: Demographic information of respondents, awareness, knowledge and perception on malaria was obtained. 96% of the respondents know that mosquito transmits malaria parasite. The respondents’ knowledge on the symptoms of malaria as persistence headache was 94% while 6% wrongly said itching and bleeding were among the symptoms of malaria. 74% have experienced mosquito bites while 26% haven't experienced it. Sleeping under treated net by the respondents was poor as only 2% of them always sleep under insecticide treated net and 44% never sleep under it.
