Life Cycles of Spider Mites: Adult female Spider Mites lay eggs on their host plants. After the eggs hatch in several days or weeks, the 1st stage larvae are taking over. After this the larvae molt into nymphal stage with additional legs and then on into adults. Some Spider Mites spend the winter as eggs but the two-spotted & the honey-locust Spider Mite overwinters as adult females. They overwinter in the soil or on host plants including crops or house plants.

Spider Mite activity usually picks up during warmer periods. The develop rapidly during this time and subsequently have higher egg production. Dryer conditions also greatly favor all Spider Mite varieties. The feed more in dry conditions. Additionally, their natural enemies usually require humid conditions to thrive.
