From time to time undomesticated or "wild" animals such as raccoons, skunks, squirrels, rats and opossums wander into residential and commercial areas. The Peninsula Humane Society advises citizens not to attempt to capture or trap wild animals. A qualified animal control company is best qualified to handle traps and animals. To find a pest control company, look in the yellow pages or do an online search for "wildlife pest control in San Mateo County."
