The tiny insects you sometimes see in the flowers on plants and in your vegetable garden could be thrips. Thrips are very small, less than 1/16th of an inch long. Mostly a nuisance pest, thrips in large numbers can cause growers big problems. Thrips will usually have a black, grey or yellow body.
Thrips can be found deep in flowers and leaves of plants and usually will feed on flower heads and leaves. Thrips feed using their mouthparts and placing them into the fruits or flowers of a plant and sucking out the juices. Thrips can wreak havoc on cultivated plants, and this can be a problem for growers. They thrive in leafy vegetables like lettuce and cabbage, and they are present all season long. Thrips will attack vegetables and fruits with high water content. These pests will create scars on the leaves of these crops and will cause commercial growers financial difficulty if they are not controlled. Some growers will not grow crops that attract thrips, which causes the price of these select crops to increase due to their scarcity.
Thrips don't only feed on vegetables. They will sometimes bite humans as well. Thrips bites will develop a rash and can sometimes be quite painful. Sometimes thrips will enter your home on clothing that has been hung outside to dry.
If you have an infestation of thrips or they are harming your plants, fruits and vegetables, consult a pest control expert. Thrips can be monitored and controlled through a variety of methods, and your pest control expert will help find the method that will work best for you.
