DIAGNOSIS: Night roosting on sheltered parts of rooves of a villa.
TREATMENT: Night roosts treated with dishes of Bird Free at 20cm centres; landing points at 25cm centres.
Night roosts were located against the walls on the upper rooves and at the rear of the lower roof. Pigeons were alighting on the front edge, and on the V-shaped raised “hips” of the lower roof. After the rooves had been disinfected, dishes of Bird Free were fitted to the upper rooves and to the rear of the lower roof (two rows) at 20cm centres to prevent night roosting; and at 25cm centres to the front and raised hips of the lower roof to prevent landing.
Two rows of Bird Free dishes were fitted at 20cm centres to the top of the pitched roof against the wall and to the rear of the lower roof shown above right to prevent night roosting. Dishes were fitted at 25cm centres to the front of the lower tiled roof and to the front of the parapet to prevent pigeons from landing.
This treatment was carried out in the daytime. The result of the installation is shown in the following video, which was taken that evening, a few hours after the installation was completed:
NOTES: Pigeons had occupied the sheltered parts of the rooves as night roosts. Their habitual landing points were the leading edges of the rooves, the front of the parapet and the V-shaped raised hips of the large lower roof. The application of Bird Free to the pigeons’ habitual night roosts rendered them uninhabitable. Consequently, there was no reason for them to return to the site.
The number of dishes of Bird Free required was calculated as follows: Night roosts: no of linear metres x 5 (at 20cm) + landing points: no of linear metres x 4 (at 25cm).
