Officials in Santa Monica, California, have tried poison, gassing and euthanasia to control a breeding frenzy among squirrels in a city park. Now KPLCTV.com reports they plan to give birth control a shot. Literally, that is. Under a new program to start this summer, squirrels in Palisades Park will be injected with an immuno-contraceptive vaccine to stunt their sexual development. ``We don't want to kill them if we don't have to,'' said Joe McGrath, the city's parks chief. ``I personally like squirrels, but we also have to be receptive to the county's concerns.''Health officials say the squirrels are aggressive and may carry rabies or host fleas that can spread disease, such as bubonic plague. Since 1998, Santa Monica has been cited five times by Los Angeles County for squirrel overpopulation. But the suppression methods it has used, including euthanasia, have angered animal activists.
City officials say the infertility shots offer a diplomatic solution. The vaccine, developed by the U.S. Department of Agriculture, stops ovulation and lactation in female squirrels, and testicular development in males. The shots, costing between $2-$10, have no side-effects such as swelling, said James Gionfriddo, a USDA wildlife biologist.
