How To Use

  1. The Romax D bait blocks should always be placed in a suitable mouse bait box.
  2. Remove any other food that is easily available in the area, do this a few days before placing the bait boxes.
  3. Place the bait boxes in the vicinity where mouse activity has been seen and out of the reach of children and pets.
  4. At the beginning check bait boxes every 2-3 days and at least weekly, refill with bait as necessary
  5. Check the area for any mouse bodies and dispose of in a suitable manner.
  6. Mice exhibit a rapid investigatory response to new objects, but their interest wanes rapidly and they move on to something new.
  7. Use bait points of 1 block in a bait box, 10m apart, reducing to 5m in heavy infestation.
  8. Mice are inquisitive so move the bait points every 2-3 days.
  9. Always check manufacturer instructions before use.
