Interviewer instructions
If the last time was within the last 2 years (24 months), record the number of months ago in the space provided. If the last time was less than 1 month ago, record '00'. If the last time was more than 24 months ago, circle '95'. If the respondent does not know the number of months, probe to obtain his/her best estimate. Circle '98' for 'DK/Not sure' only if the respondent cannot even estimate when the net was last soaked or dipped.
