Seagulls are in the middle of their nesting season (May – July).  They are not only attracted to good nesting sites but to areas with a good food supply.  Cornwall Council offer the following advice:  

• Don’t feed the gulls
• Don’t leave lids off bins
• Don’t put rubbish out too early
• Do cover rubbish sacks to prevent attack by gulls or other pests
• Seagull proof rubbish sacks can be purchased from One Stop Shops or the Town Council
• Don’t drop litter
• Avoid eating in the street.

Further deterrent advice to households for next season can be found here.
