ANOTHER ruse is being tried to discourage pesky pigeons nesting under Teignmouth pier and adding to the pollution of the sea.

A material which simulates fire but is harmless – and hopefully will frighten off the birds – is being introduced.

It is being used in conjunction with a device that gives off a sound that also deters the pests.

Both are being trialled as part of the project to clean up the polluted sea water so that it passes strict new European regulations coming into force next year.
