Abstract
A classical cluster sampling survey (420 households) was implemented in 2011 in Lobito town (Angola) to make a situation analysis of current use of mosquito net, and other mosquito control method, at household level after and before another scaling-up of LLIN in the framework of the National Malaria Control Programme (NMCP). Three main points clearly appeared (i) 94% of people implement mosquito control at household level considering mosquitoes as a nuisance due to bite (83%) and noise (63%) while their importance as vector of diseases are quoted by 22%, (ii) the mostly used method for mosquito control at familial level was still the domestic insecticide canister (# 60%) and mosquito coils (36%) while « one mosquito net/family » at least was reported from more than 50% of households and (iii) nets were mainly used to protect babies (>50%) showing a great sensitization and knowledge of the risk of malaria in babies after the first step of LLIN by NMCP targeting « at risk » groups. The main reasons reported for the non-use of mosquito nets were « lack of comfort » and « too hot » while the cost was not considered as a main reason for non-getting net. More than 80% of interviewed people were aware of LLIN and almost 70% « ready to use » if available. These information are of great importance for NMCP which did large scale distribution of LLIN targeting « less than 5 years children » and « pregnant women » and has to further elaborate and develop adapted IEC programme for the targeted universal coverage.

Malaria is still the main cause of morbidity and child mortality in Angola [1,2]
After providing to questioned families some more information about ITNs/Long Lasting Insecticide Treated Nets (LLINs) which can kill mosquitoes and avoid diseases, 354 households (84.3%) would be willing to get some but at an average price of # 1.2 $ US the unit ( ± 1.2 $ US). This is interesting to keep in mind as the National Malaria Control Programme (NMCP) scheduled large scale distribution of LLINs free of charge!. This cluster sampling survey showed that in Lobito, as well as other surveyed towns in Africa South of Sahara such as in Douala, Yaoundé etc [22,23], the nuisance is the main cause of mosquito control at household level and more than 90% of surveyed people regularly implement some methods for mosquito protection
More than 50% of surveyed people reported a regular use of bed nets for mosquito protection and a special attention is devoted to babies who are the most susceptible to malaria disease, this behavior could be linked to the previous LLIN distribution which sensitized communities and targeted babies. 85% of surveyed people knew LLIN and 67% said they
