Euca-Guard is a natural plant protection spray, containing a combination of essential oils, natural plant extracts and hydrous oxide. It can be used for sucking, chewing and leaf eating insects, such as, ants, red spider mite, whitefly, thrips, fungus gnats, heliosis and Dendrobium beetles. Unlike most other RTU sprays, Euca-Guard guards against insects for up to 14 days.
