What is the approximate weight range for adult Norway Rats?

Adult Norway rats typically weigh between 12 to 24 ounces. This weight range is characteristic of this species, making it larger compared to other common rodent species such as house mice, which generally weigh much less. Adult Norway rats, known for their robust bodies and large size, can grow significantly, and understanding their weight is important for pest control measures.

The weight range also reflects their habitat and feeding behavior; being larger allows them to consume a variety of foods and adapt to different environments. Knowledge of the Norway rat's weight can aid pest management professionals in identifying and implementing effective control strategies, as sampling techniques and bait quantities often depend on the size of the rodents one is dealing with. Therefore, recognizing that adult Norway rats fall within this specific weight range is critical for proper identification and management of this pest.
