( Latin: Passer domesticus)
This is normally a harmless, quite attractive small bird when it builds in the eaves of a house (p. 183), but in food factories and stores it can do a lot of damage, and has been called a winged rat! Sparrows eat foods, foul them with their droppings and peck holes in packaging materials. They find their way in through any small hole and soon start to build their nests in the building.
The first step in combating sparrows is to destroy their nests and prevent them from building again. They should not be poisoned, but they can be trapped and their young should be killed.
In many places it is quite simple to fix sparrow-proof netting over the windows, but if people are going in and out of a building all the time it is extremely difficult to prevent sparrows from finding their way in.
