Chula Vista, CA, hosts a thriving population of wildlife pests like rats, ground squirrels, and starlings. Rats and ground squirrels congregate on lawns and in houses looking for food and shelter. These rodents chew through wires and contaminate stores of food. They also spread diseases such as rat-bite fever and plague. Starlings build nests in attics, on the roofs of homes, or in trees on yards. Since the materials used to construct these nests is highly flammable, the pest's presence is often a fire hazard. Additionally, starlings are aggressive birds and will chase other species away from birdfeeders and nesting sites.
