The Chimney Pot Spike has been designed for seagulls, birds and pigeons causing problems on chimney cowls or chimney pots by nesting, perching or roosting. Other than noise and unpleasant mess, if seagulls make nests on chimneys it can become a real fire hazard if the chimney is in use. This pigeon and seagull deterrent is a very easy way to keep seagulls off and out of chimneys. The stainless steel strap is flexible so will fit round or square chimney pots, or around cowls, and will quickly stop seagulls and birds from landing, nesting and causing problems on roofs. Chimney Bird Guard designed for the effective control of problem pigeons and seagulls. Suitable for a wide range of chimney pots in all shapes and sizes. Easy to install, with no glue or tools required. Super flexible and measures 3.5ft long.
