Water Spraying

Just spraying water, especially in water jet spraying will control a number of insects especially the smaller ones. Aphids, plant hoppers, small caterpillars and other insects will be simply washed of the plants.

Of course with water spraying also populations of natural enemies will be affected, especially the smaller ones (e.g. egg parasitoids).
