To make matter worse, house sparrows love to build their nests in and around air vents, stoves, louvers as well as crevices of buildings. Nesting in fan vents can be especially dangerous as the nesting material could clog up the ventilation system resulting in overheating and possible fire hazard.
So, how do we overcome such nuisance and prevent problems caused by these finches?
To solve the sparrow nesting problem, we can install nettings on the vents and at the openings of the building, clean and clear the louvers regularly, and cover the crevices with hardware cloth or any suitable mesh. Before you do the above and you find that there is already a nest built with eggs or nestlings in it, remove the nest carefully prior to installing vent cover.
To minimize the problem of sparrows loitering outside your house, eateries and around garbage dumps, use birdproof trash containers and clear your garbage on a daily basis.
Because of their outgrowing numbers, house sparrows are inclined to pillage birdhouses that are meant for habitation by other bird species. To avoid this, design and customize nest boxes according to the nesting needs of your preferred bird species. Next, place the boxes about 300 feet away from houses and other buildings as house sparrows do not like to nest too far away from buildings. Finally, it is suggested to feed black oil sunflower seeds to your birds because house sparrows do not favor such food.
