Not exactly trying to attract wildlife, more getting rid of it ! We have had swallows nesting in the eves of the house for the past 2 summers. In themselves, they are lovely to have - and the cheeping of the little ones is nice. However, their poo lands all the way down the front of the house, and on the windowsills below. Before they return for another year, whats the best way to get rid of the nest ? Can I just 'jab' at it with a big stick and try to hack it away ? Or will they just decide they still like their little holiday spot, and just build another one ?
