active between 16-35°C/61-95°F but performs best at temperatures between 19-33°C/66-91°F Soil temperature below 5°C/41°F and above 35°C/95°F can be lethal [...] bacteriophora nematodes infect their hosts by entering through natural openings or the cuticle. Once inside the host, they release symbiotic bacteria, [...] Heterorhabditis bacteriophora nematodes enter the pest's body through natural openings.
