When anticoagulants are eaten daily, however, death may occur as early as the third or fourth day. For optimal lethal effects, several feedings should occur within a day period with no longer than 48 hours between feedings.
All anticoagulants provide good to excellent Norway rat control when prepared in acceptable baits. A new second-generation anticoagulant, difethialone, is presently being developed and EPA registration is anticipated in the near future.
The characteristics of the various anticoagulant rodenticides are described further in the Pesticides section. Because of their similarity in mode of action, all anticoagulant baits are used in a similar fashion. Anticoagulants have the same effect on nearly all warm-blooded animals, but the sensitivity to these toxicants varies among species.
If misused, anticoagulant rodenticides can be lethal to nontarget animals such as dogs, pigs, and cats. Additionally, residues of anticoagulants which are present in the bodies of dead or dying rodents can cause toxic effects to scavengers and predators.
In general, however, the secondary poisoning hazard from anticoagulants is relatively low. Brodifacoum and bromadiolone baits, because of their potential to be lethal in a single feeding, can be more effective than the other anticoagulants in certain situations.
Thus, they are formulated at lower concentrations. Chlorophacinone and diphacinone may kill some rats in a single feeding, but multiple feedings are needed to give adequate control of an entire rat population. It has some properties that resist insects and growth of mold in prepared baits.
It is effective against Norway rats, although some products may contain small quantities of contaminants that apparently can reduce bait acceptance. This problem was resolved by the development of micro-encapsulated warfarin. Within any population of Norway rats, some individuals are less sensitive to anticoagulants than others.
Where anticoagulants have been used over long periods of time at a particular location, there is an increased potential for the existence of a population that is somewhat resistant to the lethal effects of the baits. Such resistant populations of rats have been identified at a number of locations throughout the United States.
Although not common, resistance may be underestimated because documentation of resistance is usually not pursued by persons involved in operational rat control programs. Resistance, if and when it occurs, is of little consequence in the control of Norway rats, especially with the newer rodenticides presently available.
When anticoagulant resistance to the first-generation anticoagulants is known or suspected, use of these compounds should be avoided in favor of the second-generation anticoagulants or one of the non-anticoagulant products.
Resistance is only one and perhaps the least likely reason for failure in the control of rats with anticoagulant baits. Control with baits that are highly accepted may fail for one or more of the following reasons:Impact and Control of the Brown Tree Snake as an Invasive Species on Guam by Karen Myers Introduction “Invasive species are a rapidly growing problem, and in.

Brown Stomach Worm Ostertagia ostertagi. The infamous Ostertagia is the most economically important parasite in cattle. This worm also has a unique ability to penetrate the lining of the true stomach and become dormant, or inhibited, so that it can survive during weather that’s too cold or too hot.
