Shield bugs are plant-sucking pests producing pungent odor as a defense mechanism. They also cause wilting, stunted growth, yellow or white blotches on leaves, and black pits on nuts.
Encourage the presence of natural enemies (e.g. lady beetles, lacewings, parasitic wasps).
Prevent plant stress by optimal watering, fertilizing and protection from sun and frost.
Choose suitable neighboring plants. Remove weedy areas and plant small-flowering plants to attract native parasitic wasps and flies.
Prevent the pests from getting into your home (seal any entry points and put up the window screens).
Clean the area of infestation. Remove any nearby weeds or tall grass and any hiding places like old boards and logs.
Apply ecological products for plant protection (e.g. mineral clay, neem oil, cedar sprays).
