The objective of the study was to evaluate the effectiveness of LLINs in use and to evaluate the knowledge, attitude and practice of some net users in Kano metropolis. The effectiveness of LLINs distributed in the year 2009 in Kano metropolis in Kano State, Northern Nigeria was evaluated using a cluster sample technique A Cone bioassay with laboratory reared Anopheles were performed. Knockdown after 60 minutes and mortality after 24 hours following 3 minutes exposure were evaluated. A total of 210 households were administered with two hundred and five (205) respondents 97.6% indicated the knowledge about LLINs while five (5) respondents were not aware. Similarly, one hundred and ninety- eight respondents (94.3%) strongly believed that the washing of LLINs does not reduce the preventive role of LLINs. Very high and consistent knockdown and mortality in all replicates was found. The outcome on the use of LLINs reflects the effective use of LLINs among the respondents with two hundred and eight respondents (99%). Respondent still holds some reservation on the use of LLINs, one hundred and five respondents (54.8%) believes it causes heat. It has been observed that the respondents reply does not rely mostly on LLINs despite by Original article Contents lists available at Sjournals Journal homepage: www.Sjournals.com
