  Abstract  
  This paper evaluated the attractibility, palatability and efficacy of bromadiolone paraffin block exposed for 30 days to environmental conditions. It was used four groups of white Wistar rats: two groups received no-exposed blocks (control group) and two groups received blocks exposed for 30 days to the environment; in both cases, one of the groups received just the block and the other group received parafin block and food. The tests were repeated after 2 months. The quantity of block consumed and the mortality of the animals were registered. Despite the changed appearance of the blocks after exposure, there was no significant difference between the consumption of the no-exposed and the exposed blocks. Blocks were consumed only in groups that received just the blocks, indicating low attractiveness of the product, although it was effective, killing 80-100% of animals. There was no change in the attractibility, palatability and efficacy of bromadiolone paraffin block after environmental exposure for 30 days.
