Nematodes, from a pest insect that they had been breeding inside. While gory, #nematodes are a #biocontrol option for various invertebrate pests. Various species are available commercially, and can be effective against a range of species. They can be particularly good against insect pests with a soil-living life stage, such as #VineWeevil (and other weevils!), some #Sawflies, root maggots and other #Diptera larvae, etc. #LoadsaTodes
