Making a flytrap from glass bottle This requires a little experimentation and great care. A glass bottle with long neck is taken and thick string is soaked in petrol and tied around the bottle about 10cm below the neck. Light the string so it burns all round then plunge the bottle in water. The bottle should crack at the string point. Take care, wear goggles and gloves. Light the string and plunge into water Use the top of the bottle Encase the bottle top on concrete and allow to cure Mount the mounted bottle top over the vent hole and cover with a jam jar 18
Upgrading the simple superstructure The simple grass spiral superstructure can be upgraded in several ways. A grass roof supported by poles with plastic sheet placed between the poles and the grass protects the users from rain and also shades the interior of the toilet. This helps to reduce fly ingress into the pit. A roof is essential once a vent pipe is fitted. A squat hole cover-plate with or without a fly trap can also be fitted to reduce fly breeding and fly release into the environment. Wood ash can also be added to the pit to reduce odour and fly breeding. A screened vent pipe can also be fitted as an upgrade even to simple grass structures to reduce odours in the toilet and also to trap flies. Toilet floors can be sloped to assist in washing down with water. The next upgrade would be to replace the grass structure with brick and fit a more permanent roof and vent pipe if one has not already been fitted. Simple grass spiral superstructures can be upgraded step by step Vent pipes can also be fitted to simple grass structures Building an economical spiral brick superstructure 19
