OLD TYRES AND MILK MAKE BEST MOZZIE TRAPS
Researchers with the Grand Challenges Canada initiative have combined mosquitoes’ love for old car tyres and their own chemical expertise to design a highly-effective trap using two halves of an old tyre. The rubber is ‘significantly more effective’ at attracting mosquitos than plastic bottles or buckets. They call the trap the ovillanta, and use the mosquitoes’ habit of releasing pheromones in water containing mozzie eggs against the insects. Users mix water and a milkbased non-toxic solution, developed at Sudbury’s Laurentian University to attract mosquitoes, and place the mix in the trap with a twig or piece of paper for the female to lay the eggs on. Ovillanta owners burn these once a week, but re-use the water, as more pheremones attract more mozzies to make the trap increasingly effective.
