Although mice in Houston, TX, may seem like a small annoyance, the pests are more destructive than they appear. With a forceful bite, mice can chew through metal or wood and wreak havoc on sensitive electrical wiring. After biting and clawing their way into living rooms, attics, or sheds, they also build nests inside upholstered furniture, wall voids, and lawnmowers. Homeowners with an infestation may hear squealing noises during the night or scratching and rubbing sounds as the rodents squeeze against walls. Finally, when mice in Houston contaminate human or pet food, diseases such as salmonellosis have the potential to be spread.
