Mosquito Float Killer

Most species of mosquitoes lay their eggs in stagnant bodies of water. The first three stages of a mosquito's life - egg, larva, and pupa - are largely aquatic. As such, an efficient solution to inhibit the population of adult mosquitoes - the ones that spread malaria - is to deal with them before they become a problem. To implement the saying 'Prevention is better than cure', we present a product that kills mosquito eggs, larvae, and pupae.The prototype takes inspiration from the recently prominent invention SeaBin.The device consists of a floating cylinder with multiple layers of meshes that are weaved wide enough to trap mosquito eggs and larvae. Water is sucked in from the surface and passes through a catch bag inside the container, with a submersible water pump or a motor that creates a simulated flow through the interior of the device, driving the organisms through the outer mesh and trapping them within. The trapped organisms are then immersed in a suspension of BTI (Bacillus Thuringiensis serotype Israelensis) bacteria, which is a group of bacteria that exclusively act against and produce toxins that kill mosquitoes, gnats, and blackflies, while having almost no effect other living organisms. It operates through a motor and paddles on minimal electric power. The meshes are interlaced precisely to ensure the entrapment of objects the size of larvae, eggs and everything smaller. The constant simulated flow shall ensure a continuous ingress of organisms.The device is built to operate in stagnant bodies of water - preferably lakes, ponds, water reservoirs and dam reservoirs. The device can be charged either through solar power, or charging via mains at regular intervals. Sensors can be incorporated into the mechanism so that the device navigates to a charging stations placed nearby on low battery.The Outer shell, base, and the meshes are the parts that require 3d printing. Mesh uses very less amount of 3D printing material. The other parts of the device consist of a battery, centrifugal pump, and sensors (if necessary). The base can be installed with a holder for external pumps for a wider range and faster operation. The device also serves the additional purpose of cleaning the water bodies.The design can be scaled as per the requirement.
