Where do Spider Mites Come from?

Spider mites are somewhat related to spiders and ticks, but they’re not the same. They are very tiny and difficult to see from bare eyes unless you look carefully. Their species also spin spider-like webs but rather small and dense to protect their eggs and young mites from predators.

Spider mites transfer through eggs, from the surroundings or from the infected plants you buy from the nursery. They survive the winters in the egg stage and thrive in the warm weather. They prefer hot and dry conditions around them and become active in the spring and summers. In a hot climate, their life cycle continues year round.

Mites are the most prevalent pests that indoor plant growers face as indoor conditions are most suitable for them due to normal temperature and dry air. That’s why one of the ways to prevent spider mites is gushing water on leaves of the affected plants.
