I've never attempted it so I don't have any first-hand judgements of its effectiveness. However, the logic in the article seems reasonable. A backyard which already has a high population of mosquitoes implies the area has existing spots with standing water where the eggs are being hatched. Adding controlled spots of water would concentrate those eggs there and kill them off before they have a chance to hatch more eggs and add to the population. Then, the existing adults die off naturally within weeks, and you should be left with a "mosquito free yard"
