Insecticide-treated nets are nets for hanging over sleeping places, treated with an insecticide that repels, disables and kills mosquitoes coming into contact with them. Conventionally treated nets are effective if they have been retreated correctly within the last six months (or the last yea the case of some chemicals), not washed more than three times since the last treatment and without holes or tears. LLIN's are effective if they are not older, and have not been washed more often, than recommended by the manufacturer (commonly no more than 20 washes and no more than 3 years old) and are without large holes or tears. Nets should a be of a size and shape that allows them to be hung over the bedding used. Nets are only effective if they are hung correctly, in a way that does not allow gaps through which mosquitoes can enter.

Threshold / Standard
In many contexts people will not have access to safe drinking water for part or all of the emergency period, for example when they rely on traditional unprotected water sources or when central systems for water treatment and distribution fail. In these cases, household (or point-of-use) treatment is important for ensuring that water is clean at the point of consumption. Surveyors should check to ensure that all the necessary supplies and equipment are present. For example, if bucket disinfection is used, an additional water container, usually a bucket with a lid, will be required for the process, in addition to containers for collection and storage. Model questions for survey: Do you treat your water in any way to make it safer to drink? IF YES, what do you usually do to the water to make it safer to drink? Did you treat the water that is being used in your household today? IF NO, why not? May I see the product or device please?
It is important to see the nets installed in the household and check who actually sleeps under the nets. Possible questions: are there any pregnant women or under-five children in this household? IF 'YES', do you have a mosquito net in your household? IF 'YES', who usually sleeps under it? Can I see the net(s)? Observe the nets: is the net hanging above a bed / sleeping mat ? Does it hand in such a way that is do not allow gaps for mosquitoes to enter? Does the net see to be in good conditions ? Ask how old is the net / when was it last retreated?
