Contrac All Weather Blox, manufactured by Bell Laboratories, Inc., is a single-feeding anticoagulant rodenticide containing bromadiolone.

Contrac Blox kills various types of rats, mice, and meadow voles. Each bait block has pre-drilled holes for inserting in bait stations to provide a safer control method. Contrac Blox are made with a special food blend that rodents have a hard time refusing.

When combating the toughest infestations, Contrac Blox provides fast results, as rodents die within 2 to 4 days of eating.

Tools Needed

To apply Contrac All Weather Blox outdoors and in areas where pets, children, and non-targeted wildlife have access, a tamper-proof bait station is required.

How to Use

• Step 1: Determine the areas where rodent activity has occurred (along walls, gnawed openings, corners, concealed places, etc.). Proceed to remove as much alternative food as possible with a thorough cleanup.
• Step 2: In tamper-proof bait stations, place 1 per placement 8 to 12 feet apart for mice and 3 to 16 blocks per placement for rats spaced 15 to 30 feet apart. It is recommended to set out empty bait stations then add Contrac Blox a few days later. This will earn trust and prevent rodents from avoiding the station. Place baited stations around the perimeter of the building structure and around areas where activity has been seen.
• Step 3: Check treated areas daily to clean up any dead rodents or leftover bait. Replenish and replace spoiled bait every day for up to 15 days or until rodent activity has stopped.

Where to Use

Contrac All Weather Blox can be used indoors and outdoors. The baited blocks can be placed along walls near chew marks, under sinks, in attics, and where other rodent activity is found. If Contrac Blox are placed in areas where children, pets, or other wildlife have access, tamper-proof bait stations are required.

For outdoor areas, bait stations can be placed along perimeters of residential, commercial, and industrial building structures and along fence lines where they mostly travel. Tamper-proof bait stations filled with Contrac Blox are ideal for restaurants, manufacturing plants, hotels, hospitals, schools, and more.

Contrac Blox should not be placed over 100 feet away from any building structure or placed in random areas out in the open as most rodents travel along walls or fence lines.

When to Use

Contrac Blox can be used anytime rat, mice or meadow vole activity is recognized. Contrac Blox can also be continuously applied in areas where control is on-going for places like restaurants or manufacturing plants.
