Author(s): Colvin, Bruce A.; Swift, Trygve B.; Fothergill, Frank E. | Abstract: There were 1,288 sewer and 235 other utility manholes baited to control Norway rat (Rattus norvegicus) populations in downtown Boston using pulsed-baiting methods. About 15% of all sewer, 18% of phone, and 26% of electric manholes had rat activity. Sewer populations were most associated with residential areas with low flow, small diameter (l61 cm) brick sewers; in those circumstances, up to 38% of manholes had rat…

REPELLENTS TO REDUCE CABLE GNAWING BY WILD NORWAY RATS
TLDR
Two chemical repellents (capsicum oleoresin-capsaicin and denatonium benzoate) at 2.0% mass/mass concentrations in a polybutene carrier (Indopol®-control) were evaluated for repellent efficacy compared to a plastic mesh physical barrier material (Vexar® ) and the polybutenes carrier (placebo) alone using groups of individually caged wild Norway rats.
Rats About Town: A Systematic Review of Rat Movement in Urban Ecosystems
TLDR
It is suggested that the distances travelled by urban rats are location-specific, determined by local resource availability and barriers to movement such as roadways, while long-distance dispersal events can maintain connectivity among distant populations.
The occurrence of commensal rodents in dwellings as revealed by the 1996 English House Condition Survey
TLDR
The value of applied ecological techniques, including logistic regression of presence–absence data, is revealed in understanding the distribution of commensal rodents in relation to dwellings, with the prospect of more effective management practices being developed as a consequence.
Invasive rodents and damages to food stocks: a study in the Autonomous Harbor of Cotonou, Benin
TLDR
The results show that invasive mice and rats are, from far, the most impacting rodents in the storage warehouses, and that the associated economic losses are quite large, so that they justify financial investment in rodent population control.
RAT CONTROL by LOCAL AUTHORITIES within the UNITED KINGDOM
TLDR
A survey of all Local Authority Environmental Health Departments in England, Wales, and Northern Ireland found that external harbourages, defective drains/sewers, poor structural maintenance, and poor hygiene were identified as the most important causes of rat infestations.
Reconsidering the “War on Rats”: What We Know From Over a Century of Research Into Municipal Rat Management
To sustainably control urban rat infestations, management efforts need to encompass large areas of urban centers. Therefore, the objective of this review and narrative synthesis was to collate what
Rating the risks of anticoagulant rodenticides in the aquatic environment: a review
TLDR
Findings in raw and treated wastewater, sewage sludge, estuarine sediments, suspended particulate matter, and liver tissue of freshwater fish in the low ng/L and µg/kg range demonstrate that the aquatic environment experiences a greater risk of anticoagulant rodenticide exposure than previously thought.
Urban Rodent Control Programs for the 21 st Century
Urban rodent control in the 21 st century must focus on a program approach that is both strategic and comprehensive (i.e. proactive rather than reactive). This includes an integrated pest management

NOTES ON THE ECOLOGY OF SEWER RATS IN ST. LOUIS
TLDR
It was determined that rats hoarded cracked corn, and to a lesser degree, cornmeal; this is important, as bait consumption when seen in pest control operations may not be a reliable indication of rat abundance.
The control of rats living between access points in sewers
1. The rat population of a main sewer was studied by means of census baits. 2. In a series of poison treatments extending over 4–5 months all rats visiting the access points were eliminated. 3. At
The rates of recovery of sewer rat populations after poisoning
TLDR
The recovery, after poisoning, of the rat population of eight sewer systems was measured by the bait-census method, and the consequences for control of a rate of increase as low as 3% per week are discussed.
The control of re-invasion by rats of part of a sewer network.
TLDR
It is concluded that the type of poison-bait barrier used in the present trials is insufficient to prevent invasion of one part of a sewer network from another if the population density in the latter is high.
Population dynamics of sewer rats
TLDR
The rate at which the population was restored from the 3% level was even higher than the rates previously observed, and was probably too high to be accounted for solely by breeding.
Efficacy of alpha-chlorhydrin in sewer rat control
TLDR
Comparisons of changes in rat densities in infested sewers following the two treatments indicate that recovery of warfarin treated populations is achieved by reproductive recruitment followed by dispersal while α-chlorhydrin treated populations recover by slower immigration and later reproductive recruitment.
PULSED BAITING —A NEW TECHNIQUE FOR HIGH POTENCY, SLOW ACTING RODENTICIDES
TLDR
The advent of a highly potent but slow-acting rodenticide molecule, brodifacoum, has allowed the development of the pulsed baiting technique, which is highly effective and offers very significant savings both in bait and labour compared to first-generation anticoagulants, with excellent levels of control.

TLDR
Sewer baiting resources are allocated for sewer baiting for a number of reasons to ensure that rodent infestation does not attain unacceptable levels in the environment and to prevent blockages in the Authority's sewers.
