Surrounded by desert, Casa Grande, AZ, sees its fair share of pests. Coyotes commonly hang around residential neighborhoods. Though the animals were once too timid to approach humans, they now associate people with the availability of food. Therefore, they may get too close to individuals or their pets and attack, which leads to injury. Roof rats are also frequently found in the Casa Grande area and invade homes easily thanks to their climbing ability. They scale trees and use vines or telephone lines to access roofs and infest attics. Once inside, the rodents reproduce quickly, gnaw holes in walls, and urinate and defecate throughout homes.
