From Canada, the ovillanta is a clever — and highly effective — mosquito trap made from the pests’ favourite breeding spot.

Dr. Gerardo Ulibarri, PhD, an associate professor of medicinal chemistry and eco-health at Laurentian University in Sudbury, Ontario, had a brilliant insight recycling tyres to create an effective mosquito trap that may provide an easy to build and effective mosquito management solution. Made from recycled tyres the bottom half of the device gets filled with about 2 litres of water, topped with so-called “landing strips” – pieces of Pellon or germinating paper, for example – on which the female mosquitoes lay eggs. Mosquitoes weed moisture to hatchso the landing paper if white easily shows the eggs. About once per week the user empties the device destroy the eggs, pour the water back into the ovillanta (topping it off with fresh water) and install two new landing strips. “It’s important to recycle the water because after the eggs hatch, they release a pheromone into the water that tells other mosquitoes it’s a good, safe place to lay eggs,” says Ulibarri, who’s work is funded by Grand Challenges Canada.
