Control spider mites organically with Mesoseiulus longpipes. These spider mite predators thrive in warm, dry climates. They are effective in lower humidities than P. persimilis. M. longipes are effective in temperatures up to 100_F, although a comparable increase in humidity is required. Apply these predators in warm greenhouses and interiorscapes with artificial lighting or in outdoor settings with suitable conditions. The lower humidity needs of M. longipes make it ideal for controlling spider mite infestations on taller plants in greenhouses.
