A flock of around 150 squawking seagulls have got fed-up residents in an area of March in a flap.
They are plaguing residents with their constant screeching after taking up residence on the roof of Davern Workwear in Elliott Road.
The protected species are waking residents in neighbouring Harvester Close in the early hours and dropping excrement everywhere.
It is the third or fourth year the gulls have nested on the roof despite measures to deter them.
One resident, who did not want to be named, said the problem starts at the beginning of the breeding season and lasts until August.
She said: “It’s a complete nightmare. They squawk constantly throughout the day and wake me up every day between 3am and 6am. The noise is unbelievable.
“I can’t have my windows open at night if it’s hot and I can’t enjoy my garden.”
She also said she can’t hang washing out as it always gets messed on and she has to constantly clean up mess from her windows and car.
She added: “Davern have put up spikes to try to deter the gulls but they just walk around them. We have been trying to get something done, but it is difficult because the birds are protected.”
A spokesman for Fenland District Council said: “This is an ongoing problem at Davern Workwear, as it is elsewhere, and we have been in touch with them about it for some time. However, there are limits to what we can do.
“Seagulls are protected under the Wildlife and Countryside Act 1981 and it is illegal to do anything that will cause them suffering. All we can do is encourage people, including businesses, to take the appropriate preventative measures; we don’t have the power to force them to do so.
“Davern did employ a specialist contractor in July 2013 to remove nests and install bird-proofing measures on to the roof. We have contacted them several times this year to encourage them to take further measures.
“We sympathise with residents and businesses who are experiencing the problem and continue to do all in our power to help them. Advice about preventative measures can be found on our website, www.fenland.gov.uk.”
