Real-life scenarios and results

In spaces such as garages, sheds, barns, and storage facilities, CONTRAC BLOX blocks offer a practical option for ongoing rodent management. The palatable formula paired with a weather-resistant design helps maintain access to bait across varying conditions, while the 18 lb format supports placement across multiple stations or larger areas.
