Catnip lotion proves as effective as Deet in repelling mosquitoes, study finds
via The Namibian4 min read
A recent study conducted in Uganda has shown that a catnip-based lotion is as effective as diethyltoluamide Deet in repelling mosquitoes. The research, presented at the Society for Experimental Biology conference in Florence, found that mosquitoes were less likely to land on individuals using lotions containing catnip. Specifically, a 6% catnip oil solution performed comparably to Deet, while a 2% concentration was only slightly less effective. This development is significant for malaria prevention, especially in African countries where the disease infects approximately 282 million people annually and caused 610,000 deaths in 2024, predominantly among young children. Concerns about rising insecticide resistance and the high cost of commercial repellents like Deet for rural Ugandan subsistence farmers highlight the need for affordable, locally produced alternatives. The catnip lotion, which can be made by community enterprises, has been distributed for free through grant funding, with plans to increase production and sales to create a sustainable income for workers. Swai Kyeba, a research entomologist from the Ifakara Health Institute in Tanzania, emphasized the importance of new, accessible vector-control tools in the fight against malaria.

Must ReadThis year's Red List of endangered species highlights how human activities are overwhelming the ingenious survival strategies of various species. Deep-sea mining, for instance, threatens two-thirds of mollusc species found exclusively on hydrothermal vents, with over 200 species living in these extreme environments. One snail, Lirapex felix, is critically endangered due to mining in the Indian Ocean, though some vent species are protected in marine areas. The desert rain frog is also at risk from diamond mining and energy infrastructure expansion in Southern Africa, compounded by demand from the exotic pet trade. However, conservation efforts can succeed, as demonstrated by the numbat, an Australian marsupial. Its population has rebounded from 300 in the late 1970s to between 2,000 and 3,000 today, moving from endangered to near threatened, thanks to protection from feral cats and foxes, captive breeding, and translocations. Despite this success, five other Australian marsupials have been confirmed extinct, likely due to feral predators. The International Union for Conservation of Nature IUCN, which produces the Red List, notes that while life adapts to hostile habitats, increasing pressures threaten even the most resilient creatures. The IUCN advocates for conservation, having voted for a moratorium on deep-sea mining in 2021. The Red List currently includes 175,909 species, with 49,505 threatened with extinction.
