One of the main distributors of The Mosquito, which uses sound to deter teenagers, has today confirmed that a number of businesses in the city are keen to get hold of the product.

At least two businesses in the city have arranged product briefings for next week, said Les Devlin, of Devlin Retail Systems in Dublin.

The Mosquito has been creating a buzz in recent months as it garners a reputation as one of the most effective anti-social behaviour deterrents on the market.

The device operates by emitting a high-frequency tone, which is audible only to teenagers. Research has shown that the over 25s are unlikely to be effected by the product, due to a natural deterioration in hearing.

Mr Devlin, who has been distributing the product for patent holders Compound Security for the last year, said he has been inundated by inquiries from Northern Ireland in recent months.

He has also confirmed that a major shopping development in the North West area has expressed interest in the product and that he will meet with at least two businesses in Derry next week with a view to establishing a contract.

Meanwhile, Letterkenny Town Council is said to be considering the use of the product to curb anti-social behaviour caused by youths in some parts of the town.

Former Mayor of Letterkenny and Fianna Fail councillor Damien Blake, however, suggested that the adoption of the device remains at discussion stages.

"The use of the device has been raised at discussion at the council policing committees and we have invited the group who distributes it in to tell us more about it and see if it is suitable for certain areas in Letterkenny," he said.
