Gulls are probably the fastest growing population of pest birds in the UK. Their behaviour has altered over the past 20 years and they now prefer to build their nests on rooftops rather than cliff faces.

Gulls are scavengers and feed from scraps of food in town centers as well as sewerage outlets and domestic refuse tips.

Gulls are large and aggressive and have been known to attack people as well as domestic pets and other animals.

The noise, mess and smell associated with with Gulls can often become intolerable for people working in buildings where a gull colony has been established. Once a colony has been established, gulls will return year after year.

The number of gull breeding colonies on rooftops in the UK is increasing by nearly 30% a year.
