Alligator Infestations Homeowners in the Southern U.S. occasionally encounter alligators. While they prefer to stay outside and away from people, the reptiles sometimes enter homes. They're mostly likely to be found inside searching for food and shelter or for mating reasons. Since the pests are so large, they're typically only able to enter homes through open doors or garages. When faced with alligators in houses, individuals must act quickly to prevent personal injury and property damage. Removal If there is an alligator in the house, do not attempt to remove it. Instead, vacate the premises, and call the experts at Critter Control. Professionals are best equipped to handle infestations of the dangerous pests. Before it comes to this, homeowners can take action to prevent alligator activity, such as never feeding the animals and disposing of meat in secure trash bins.
