BlueMax Mini Blocks, manufactured by Liphatech, are formulated with the anticoagulant Difethialone to eliminate rats and mice quickly. 

The mini bait blocks are made with mold inhibitors and paraffin wax to ensure they do not spoil and get ruined in humid areas. BlueMax Mini Blocks can easily be placed between walls and directly into rodent burrows to reach the rodents where they hide.

The blue marker dye in the bait will appear in rodent droppings to signify that the rodents are eating the bait. The blocks will not break apart into crumbs when fed on and will not be quickly scattered by rodents, making them ideal for use in food services areas. BlueMax Mini Blocks are efficient with heavy infestations and safe for indoor and outdoor use.

Tools Needed

Tools are not needed to apply. However, a tamper-proof bait station is required when using bait blocks outdoors. Always wear gloves when handling bait and bait stations to prevent rodents from smelling human scents.

How to Use

Bait Station placement

  • Step 1: Determine where the target rodents have been active and will most likely consume the bait (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 to 2 blocks per placement 8 to 12 feet apart for mice and 5 to 23 blocks per placement for rats spaced 15 to 30 feet apart.
  • Step 3: Monitor bait stations and maintain a fresh supply of bait by removing old bait and replenishing the stations with new bait blocks. Continue replenishing stations with bait for 10 days or until the target rodents are found dead and activity has ceased.

Where to Use

BlueMax Mini Blocks can be used inside and outside residential, commercial, and industrial areas where mice and rat activity have been identified. Blocks can be applied near trash receptacles and in transport equipment such as ships, trains, and aircraft. Bait blocks can be inserted directly into rodent burrows.

BlueMax Mini Blocks cannot be broadcast outdoors and cannot be applied to food or feed crop areas. BlueMax Mini Blocks are ideal for use in damp areas susceptible to mold, humid areas, and places where moisture is a concern.

When to Use

They can be applied anytime rodent activity is suspected or confirmed.

Keith's Pro Tips"When baiting for rodents, you should leave the bait station in an active area unbaited. After a few days pass, then add bait to the station. This gives rodents time to get accustomed to the station and lulls them into a false sense of security so they won't avoid it when baited."
Product DrawbacksBlueMax Mini Blocks are not labeled to control meadow voles. To control meadow voles, we recommend using Contract with Lumitrack Rodenticide.
