The MIAT Prize 2019


Mosquitoes are regarded as the most dangerous animal on the planet, as they cause the deaths of just under one million people each year. They transmit a variety of deadly and harmful diseases, the most infamous being Malaria, Zika and Dengue. Currently, developing countries invest huge amounts of money in a variety of schemes to reduce the number of mosquitoes. Female mosquitoes lay their eggs in bodies of water, aiming for small stagnant pools, which do not contain fish. This makes the chance of the larvae surviving higher because there are no predators or water current to kill the larvae.

A huge problem faced in developing countries is the lack of fresh water. Many countries have invested in rainwater harvesting tanks as a way of combating the water shortages. Through these periods of water shortages, if users need to wash or drink, they must use the tanks as their primary water source. These tanks are used only as a last resort. This obviously contributes to the current mosquito problem as these water tanks (which number in the thousands) offer a safe and sheltered environment; perfect for breeding (stagnant water).

Guppy, finalist 2018

The ‘Guppy’ is a device that disturbs the water surface. By mimicking predator characteristics and creating a small water current, the environment becomes inhospitable for mosquito breeding. This in turn prevents mosquitoes from landing on the water and laying eggs. Any larvae that are currently on the surface of the water are quickly drowned by the waves. The utilisation of low cost manufacturing methods, sustainable design and small size means that this product offers a cheap and efficient alternative to other products in the market.
