Warwickshire Police have been granted the power to disperse groups of youths in two parts of the county.
Police say they are being called to deal with regular complaints about anti-social behaviour in both Lighthorne Heath and Shipston-on-Stour.
Residents have reported being sworn at by teenagers, who are also accused of throwing eggs at homes and cars.
The powers allow police to move on groups gathering on any public land. Those who refuse can be arrested.
'Intimidating and distressing'
Stratford-on-Avon police have been granted authority under the Anti-Social Behaviour Act of 2003 to disperse groups of under-18s gathering in areas including roads, footpaths and grass verges.
Sgt Warren Ayers, rural community officer, said: "For over a year now police have received a high number of complaints from local residents in Lighthorne Heath and Shipston town centre about the anti-social behaviour of individuals and groups.
"The behaviour is both intimidating and distressing for local residents and totally unacceptable.
"Anyone refusing to adhere to instructions given by officers will be liable to arrest and prosecution."
