1994: Blood-clotting response test for
bromadiolone resistance in Norway rats.
A thorough examination of history, clinical manifestations, blood, nasal swab and X-rays revealed that epistaxis in 01 (2.22%), 04 (8.88%),10 (22.22%) and 30 (66.66%) cases was due to aspergillosis,
bromadiolone (rodenticide) poisoning , trauma and ehrlichiosis respectively.
Now controllers use a rodent killer made from
bromadiolone. But gradually both types of poison are ceasing to be effective on some rats.
Now rat-catchers use a rodent killer made from
bromadiolone but Sean says neither of these are working on some rats.
Second-generation products such as brodifacoum, difethialone and
bromadiolone are more toxic than first-generation products such as warfarin, diphacinone and chlorophacinone, and can kill a rodent after just one dose, and within 48 hours.
Rats are Killed typically by using rodenticides such as Warfarin,
bromadiolone and difenacoum.
Examples include imidacloprid, a gel bait for cockroaches;
bromadiolone, a block bait for rodents; and d-Phenothrin, a micro-emulsion concentrate for flies and mosquitoes.
