Keep your home and surrounding area free of garbage that might create a food source for seagulls. Put lids on garbage bins and bring pet food inside or under a covered area.
Do not place food, such as bread or vegetables, out for other birds or wild animals, or feed the seagulls deliberately.
Discourage nesting on your roof or eaves by installing deterrents such as roof spikes, plastic owls or wire mesh. If you need to take these measures, do so before the nesting season for the best results.
Contact a local licensed pest control company for seagull removal if they are already established and are becoming a major problem around your home. A pest control company will be able to assess the situation and will follow regulated procedures for removal.
