The Council said it eliminated more than 56000 fly points in 2024, which cost more than £ 1 million.
As part of a new compliance policy, the fixed sanction notices for those captured to fly from £ 400 to £ 1,000.
The Council said the increase is in line with other London advice and is an answer to the growing problem.
The new policy also includes a community compliance team to ensure that the costs of environmental crimes are recovered without burning residents.
Croydon’s executive mayor Jason Perry said: “The turnover is a selfish crime that falls for taxpayers to pay cleanliness.
“Increasing fines is just one of the ways in which we are addressing this problem to restore pride in our municipality.
“We will continuously prosecute where we have the evidence to do so, so I encourage anyone who sees magnary crimes such as flying in the municipality to inform the details to the counter.”
The Council said that environmental crimes such as flies tip have a “real negative impact on local communities”, since “they make impurity areas, make the issue feel insecure and can encourage other forms of antisocial behavior.”
The fly tip in Croydon can be reported to the Council through the streets of Love Clean.
The Council said that through the waste and street cleaning contract with Veolia, 95 percent of all reported flies are cleared within 24 hours.
