Kill thrips in the garden using natural insecticides. Prevent thrips damage from marring the flowers of your plants and fruit trees. Thrip control products, picture, and information.
Thrips are tiny flying insect pests that damage the flowers, stems and foliage of a wide variety of garden plants by sucking at them.
There are many kinds of thrips:
Thrips have slim bodies about 1/20th of an inch long. They are brown, yellow or orange in color. The adults have fringed wings.
The thrips drawing above shows what they look like under a microscope.
To the naked eye, they look like tiny colored dashes running around your flowers.
If you suspect thrip damage, pluck a bloom and pull the petals apart. Thrips are very mobile and tend to hide in the folds between the flower petals.
They can fly from plant to plant. They also let wind currents carry them from place to place. Once they land on a plant they like, they crawl all over it.
Misshapen flowers that fail to open fully or even to open at all and silvery, mottled leaves are the visible signs of thrip damage.
