A complete life cycle can take as little as 5 days depending on the temperature. Similar to the Two-Spotted Spider Mite, the warmer the temperature the faster they reproduce. Females out number the males 4:1. Females lay up to 3 eggs per in their 35-day lifetime. The eggs take a few days to hatch and are oval and 2x the size of two-spotted mite eggs. Each Persimilis eats 5-30 Spider Mite adults or eggs per day. Because Persimilis do not diapause (go into hibernation) they can be used year-round in greenhouses and climates that remain warm during all year.
Persimilis needs relative humidities greater than 60%.. In low humidity conditions, raise the humidity by lightly misting plants or wetting walkways.
