Put protective gloves on. Wash the net by putting soap and water in a container and giving it a thorough rinse.
Measure out how much water you will need to mix with the insecticide using a measuring jug; for one synthetic net you need one pint of water, but for a cotton net you will require four pints of water. Mix the correct amount of insecticide with the water. Insecticide may come in single tablets or sachets that will be one dose, or in a bottle that will have instructions printed on it telling you how much to use.
Put the net in the container with the water and insecticide mix; ensure that all of it is submerged and that it is given time to soak into all areas of the net.
Remove the net from the mix and give it a gentle squeeze to get rid of excess insecticide in order to speed up drying.
Lie the net flat on the ground and in a shaded area while it drys; at first it will smell of the product, but this will go after a few days.
Pour the remaining insecticide down the toilet and flush. Clean the basin thoroughly with water, and safely throw away the insecticide container and the protective gloves.
