Preston — Town officials are considering a third option to remove nuisance geese from Preston Community Park, a spray treatment called Flight Control for grassy surfaces that would make the grass distasteful and gives it an ultraviolet reflective glare that also discourages the birds.

A representative from the company Tru Green of Warwick, R.I., will tour the park on Tuesday morning to provide a cost estimate and more information about the product.

First Selectman Robert Congdon said the entire park would not have to be sprayed, but only the “high contact” areas where the geese prefer to go.

The spray is approved for use on recreation fields in Connecticut, said resident Sean Nugent, who researched the product for the Board of Selectmen.

For the past four months, town officials have been discussing how to solve a persistent problem of Canada geese gathering at Preston Community Park every year. The geese have soiled sports playing fields to the point where youth sports teams have canceled or moved practices and games.

The latest suggestion follows a recent debate between the Parks and Recreation Department's plan to hire the U.S. Department of Agriculture Wildlife Services for $5,275 to trap and euthanize the geese and to harass them with pyrotechnics, remote vehicles and other methods and a proposal to the Board of Selectmen to hire trained dogs with a handler to chase the geese.

Cynthia Shanley, owner of Border Patrol Goose Control of Mystic, said the dogs would have to visit the park three times a day at different times to make the geese believe that the dog predators are permanently at the park. While Shanley didn't submit a specific price, the cost would be about $60 per visit.

Selectmen stated they prefer a non-lethal method of removing the geese from the park, while the Parks and Recreation Department opposed bringing in trained dogs to a park where dogs are not allowed.
