The two most common kinds of squirrels found in Houston, TX, are the eastern gray squirrel and the fox squirrel. Their yard antics can range from entertaining to annoying as they tirelessly try to outwit birdfeeders and bury nuts in lawns. The act becomes much less pleasant when the animals move indoors and start scratching around in attics and walls. The noises they produce are often the first indication for Houston homeowners that the attic has been breached. In addition to making disturbing sounds, squirrels also habitually chew on things like electrical wiring, creating the risk of fire.
