The StopRats team in Swaziland publishes a paper in the open access journal PLoS ONE. This paper shows that Domestic Cats and Dogs Create a Landscape of Fear for Pest Rodents around Rural Homesteads. Although many people claim that keeping a cat around the home will reduce rodent problems, there has actually been very little scientific evidence supporting the use of domestic cats or dogs, or explaining the mechanism of any rodent control. Findings of the research show that one likely mechanism through which rodent problems may be reduced, is the effect that cats and dogs have on the foraging behaviour of pest rodents. Like most prey animal species, rodents are able to detect the presence of predators in their environment. When the risk of predation is perceived to be higher, rodents will spend less time looking for food in that area. Researchers used this phenomenon to understand the landscape of fear around rural homesteads in Swaziland.  More details can be found in the NRI press release.

The lead author of the paper, Themb’alilahlwa A. M. Mahlaba from the University of Swaziland, was interviewed on South African radio station 702 about the outcomes of the paper.  The interview can be listened to here.

StopRats has produced a practical video on how to control rats. This short video describes some of the problems farmers face with rodent pests and gives an overview on how best to control rodent pests and is available in English, French and Kiswahili.



The StopRats project has its final project meeting in Arusha, Tanzania.  The meeting was organised as a scientific conference and was attended by many of the students who have been involved in the StopRats project.  Students were able to give presentations about the work they did as part of StopRats, further enabling students by providing them with the experience of giving a scientific presentation and interacting with an international group of scientists.  The project has produced a variety of publications, not just scientific publications, but a number of other information sources including videos, posters, radio and internet programmes and a new internet based centre for rodent knowledge and expertise

With a focus on capacity building and training, StopRats was able to engage with a large number of students and staff from a range of institutions in each country.  During the three years of the StopRats project, four field schools were held in different regions of Africa where a total of 81 people attended. More than 40 students were involved in the project where StopRats activities became part of their degree studies with several PhD, Masters, Bachelors and License degree students being supported by StopRats activities and project partners. The great success of StopRats was how it enabled the sharing of knowledge, expertise and experimental samples among partners as well as with many other institutions.  This network of experts from different countries and institutions will be one of the main legacies of the StopRats project. Further success on capacity building of civil society groups and the general public was achieved by awareness raising campaigns about rodents, the problems they cause and sustainable solutions where the StopRats teams engaged with private sector companies, local and regional government, rural farming communities in each target country.

StopRats partners at the ARC-PPRI in South Africa hold a final meeting with community members involved in demonstration trials evaluating hermetic bags to protect grain against rodents.  Feedback from farmers agreed with the scientific results obtained indicating that the hermetic storage bags do offer a higher level of protection than the typical woven poly bags traditionally used.  Rodents do not appear to gnaw through the hermetic bags, probably because they can not smell the grain inside the bags.  The hermetic bags were also very good in protecting the grain against insect attack.

Research on the rodent borne disease Leptospirosis is published in the open access journal PLoS Neglected Tropical Diseases.  This work, partly supported by the StopRats project, provides some insight as to why the disease remains poorly diagnosed in Africa.  Using locally circulating leptospire serovars leads to a much increased detection rate.  Furthermore, the work provides clear evidence that some pathogenic serovars can be found in a wide range of reservoir hosts including rodents, shrews, bats, cattle, pigs and fish.  The open access article can be found at Leptospira Serovars for Diagnosis of Leptospirosis in Humans and Animals in Africa: Common Leptospira Isolates and Reservoir Hosts

Hermetic storage demonstration trials were set up with farmers at Block Mokone, Stinkwater, Gauteng, South Africa. ARC-PPRI staff member, Fanie Malebana, explained the trial to the members of the maize producers club. The bags were then placed in position where the householders would store their maize. The bags are promoted to control insect pests but it is not known whether they protect against rodents as well.

A StopRats field school in South Africa was held from the 1st to 8th March 2015. 18 students from Germany, South Africa, Madagascar, Swaziland and Namibia participated in a field ecology field school at Lajuma Research Centre in the western Soutpansberg Mountains of Limpopo hosted by the University of Venda's SARChI Chair and funded by the StopRats project. Field activities and lectures led by various experts centred on projects involving small mammals (rodent, shrew and elephant shrew) trapping programmes, bats (acoustic, harp trap and mistnet surveys), birds (mistnetting and bird ringing), samango monkeys (scan samples to conduct activity budgets of resident troops), and parasitology (microscopic analysis of ectoparasites and endoparasites on small mammals and bats). Students ranged from honours-level to PHD-level and the feedback was overwhelmingly positive. From some students this field school was the first opportunity to practically apply theoretical knowledge previously based only on classroom experiences.

A StopRats stakeholder workshop for Ecologically-Based Rodent Management (EBRM) was held in South Africa over the 16th to 17th February 2015. StopRats partners from the University of Venda's SARChI Chair and the Agricultural Research Council-Plant Protection Research Institute organised a two-day workshop to bring together stakeholders from affected rural communities in Limpopo Province (18 residents of Vyeboom and Ka-Ndengeza villages where StopRats activities are taking place), the pest control industry, research organizations and the Limpopo Department of Agriculture. The 30 participants were organized into groups representing the two villages and then a third group representing industry, research and government. Translators were present to capture the responses of rural farmers to three questions: 1) are rodents a problem?; 2) how do you solve this problem; 3) whose problem is it? This approach elicited a real understanding of the very serious impact of rodents on individual livelihoods and human health in rural villages. Pathways to improve extension services and educational material were discussed with the government and industry groups. The ARC has developed "plant clinics" to advise rural communities on crop protection and this approach will be trialled in Limpopo to address rodent crop damage aspects. A report will be drafted with feedback to local communities expected by mid-2015.

Demonstrating new technology to farmers and building their capacity to develop appropriate interventions is happening across the StopRats countries.  One important aspect of rat damage repeated raised by farmers is damage to stored grain.  New hermetic bags are being developed largely to stop insect pests in stored commodities but it is not known whether the bags can equally protect grain from rat damage. Some StopRats partners are demonstrating these bags with farming communities as a way to determine whether they can be an appropriate technology to prevent rodent damage. So far, results are promising.
