Correct use of mosquito nets is essential if accommodation is not air- conditioned. For added protection of up to 3 months or longer, a safe and effective treatment which can be used on curtains and drapes as well as mosquito nets is to soak the nets in 1% solution of PERMETHRIN (or other repellent /insecticide). If resident in a malaria area, curtains can be treated in a similar manner.
The chemical is available from SHELL as a 20% emulsifiable concentrate (EC) and from ICI as 'AMBUSH' 50% EC. The application rate is 0.5g/sqm of net. Therefore a net of 6 sqm using 25% permethrin EC will require 6m x 0.5g/sqm = 3g permethrin. This is contained in 3g x 100 / 20 = 15ml of 20% EC or 3gx100 / 50 = 6ml of 50%. Experience has found that approximately 150ml of water is required as a wetting agent.
Suggested method:
1. Mix EC with water in measured quantities
2. Ruffle the net and place in a stout plastic sack
3. Pour the permethrin solution over the net in the plastic bag
4. Hold the plastic bag at the neck and work the bag to ensure the permethrin solution is applied over the entire surface of the net.
5. Take out the damp net and place it on top of the plastic bag to dry.
6. If there is residual solution in the bag, repeat 2, 4 and 5 again.
A mosquito net treated in this way is effective for up to three months.
