Villagers in West Dereham say their lives are being made a misery by a fly infestation.
More than 50 complaints have been made to the Environment Agency which is investigating potential sources where flies may be breeding.
Residents say their homes have been full of hundreds of flies for the last two to three weeks.
They also suffered the same problem periodically over the past three years.
Tamsin Raines, who lives in the village, said the problem was so bad she was considering moving out of her home temporarily.
She said: “It has been going on for two to three weeks and it’s getting worse.
“I have a six-year-old little girl. She was trying to eat her breakfast this morning and had four flies floating in the cereal bowl.”
She also said it was difficult to sleep at night because of the flies.
“It would be nice to have a definitive answer as to what the cause is,” she said.
Another villager, Jenny Simpson, said: “I can’t explain how horrendous it is. We have reached breaking point.
“Feelings are running really high as this is the third year it has happened.”
Resident James Folly said: “There were 300 flies in my kitchen this afternoon.
“I have worked in Africa and it’s not as bad as this.
“For three years we have had this now. If there is a problem it should be eradicated.
“We feel like we’re banging our heads against a brick wall.”
Now villagers are calling on South West Norfolk MP Elizabeth Truss to intervene.
An online petition, which will be passed to Ms Truss, states: “The excessive number of flies present in the village (and surrounding villages) is having a detrimental effect on the lives of the inhabitants and their families.
“A constant threat of disease and bacteria, material internal damage to property and expenditure on sprays, screens, tapes and specialist equipment is making people’s lives a misery.
“We are asking our MP to take action on our behalf.”
A spokesman for the Environment Agency said representatives had visited a site last month and seen ‘flies present at a level that could potentially cause annoyance off site.’
“We also witnessed significant levels of flies at some nearby properties,” said the spokesman.
“It is important to note that we did not see any evidence of flies breeding at the site, unlike last year.”
As a result, the Environment Agency requested an action plan from the company which has been provided and approved.
The spokesman said: “We visited site on Friday, October 5 and saw reduced numbers of flies compared to the previous week.”
The spokesman added the situation and progress with the action plan would be monitored.
“We will continue to investigate sources away from the site where the flies may be breeding,” he said.
