Where to Find Them on Your Property?

You can find Thrips on plants because that is what they eat. They may attack your flowers, leaves, fruits, twigs, or buds. They especially love Daisy flower heads, Dandelions, and Horse chestnuts. A few species sometimes feed on fungal spores and the eggs and larvae of other insects. They often make their way into your house by being accidentally carried inside on potted plants or cut flowers. Not as commonly, they may be carried in on laundry that was left outside to dry.
