Abstract:
Rodents have been a menace to man for generations inflicting billions
of dollars of crop and commodity damage each year. Rats and mice serve
as reservoirs of numerous diseases transmitted to humans, such as
plague, leptospirosis, Lyme disease, and rat bite fever. Millions of
people died during the middle ages because of the spread of plague by
rat in Europe. Rodent control products have been developed over the
centuries including traps, glues, and chemical methods (rodenticides).
Initial acute, or fast acting products were introduced and contained
chemicals having no antidotes, such as arsenic, ANTU
(α-naphthylthiourea), sodium monofluroacetate, strychnine, and
norbormide. It was not until the late 1950s that rodent control was
dramatically changed by the development and marketing of warfarin. The
chemical is classified as an anticoagulant, or blood-thinner, and
inhibits the production of vitamin K within the rodent, resulting in
death over several days. After warfarin's initial success, other
anticoagulants were added to the marketplace, including coumatetralyl,
chlorophacinone, pindone, and diphacinone. The compounds came to be
known as 'first generation anticoagulants'. These novel rodenticides
quickly reduced the use of acute rodenticides which have no antidotes.
Beginning in the early 1980s the more toxic 'second generation'
chemicals were introduced into the marketplace, including brodifacoum,
bromadiolone, and difethialone. The use of the chemicals soon began to
diminish the use of the less toxic first generation group. This took
place because of the perceived genetic resistance developed in US
rodents. The lower dose baits were seen as the newest rodent management
success story. As early as 1958 there were reports of warfarin
resistance in Scotland in the Norway rat (Rattus norvegicus).
After prolonged use of warfarin in the US, resistance was documented
(based on WHO criteria) and published. Consequently, more toxic
anticoagulants were synthesized to overcome the genetic resistance
reports. The rodent control industry over a period of only a few years,
moved from the first to second generation rodent baits. The marketing
strategy was to: 1) implicate first generation rodenticides as
ineffective against rats and mice and, 2) argue that the newer baits
could kill rodents in a 'single feeding' (2nd generation rodenticides)
compared to the 'multiple feeding' required by the 1st generation
products. In the professional pest control industry, the goal was to
convince the technician that more bait would be required with the less
toxic products. It was economically cost effective to use less bait in a
rodent control program. It was a good marketing idea, but in reality
the story had its flaws.
