A team from Canada and Mexico has successfully tested a low-cost, environmentally-friendly way of destroying the eggs of the mosquito genus that spreads dengue, and is likely spreading the Zika virus, according to an article on the Infection Control Today website.
The system includes an trap called an "ovillanta," created from two 50 cm sections of an old car tire, fashioned into a mouth-like shape, with a fluid release valve at the bottom.
A non-toxic solution is added to lure mosquitoes is places inside the tire. Floating in the solution is a strip on which the female insect lays her eggs. The strip is removed twice weekly, analyzed, and the eggs destroyed.
During the 10-month study, the team collected and destroyed over 18,100 Aedes eggs per month using 84 ovillantas in seven neighborhoods in Guatemala.
