What is Deadfast Mouse & Rat Killer Plus Blocks?

If you have a rat or mouse infestation, now is the time to call on Deadfast Mouse & Rat Killer Plus Blocks. These easy to store, handle and use 20g blocks contain Difethialone. This is the most innovative anticoagulant in the biocidal market, with no known resistance in rodents. Developed to be effective at only 25ppm, it ensures that rodents consume a lethal dose the first time. This bait is even ideal for large infestations.

The poison blocks have excellent stability in high moisture and dusty conditions. They are stable at a wide temperature range (-15° to +50°C), easy to spike, rod and replace.

How Do I Use Deadfast Mouse & Rat Killer Plus Blocks?

Only use this poison in tamper proof bait stations, like the Deadfast Rat Killer Bait Station! Use indoors for Rats and Mice. Use Outdoors, around buildings, for Rats only.

Before use, refer to the rear of the box for user instructions and application rates depending on your infestation requirements.

In general, before using bait, remove readily available food such as spilled grain or food waste. Apart from this, do not clean or disturb the affected area before treatment. This will only act to disturb the rodents and make acceptance of bait less likely.

In general, while using the bait, visit bait stations after application to:

  • Check the bait is accepted
  • Remove dead rodents
  • Re-fill bait when necessary
