What are the little tiny yellow bugs that bite?

Thrips are the tiny yellow bugs that bite humans. There are various colors of thrips ranging from black to yellow. The yellow Thrips are called Frankliniella Occidentalis and are the smallest among other Thrips. They grow to be about 1/50th of an inch long and feed on plant matter.

Among the various yellow bugs that roam your garden, some of them are Thrips. They do not only have a yellowish color as there are other Thrips with different colors in nature. Their color ranges from yellow to black, and their size depends on their color.

Thrips are plant bugs and feed on plant matter. The yellow Thrips are the smallest among the others and grow to be about 1/50th of an inch. They are almost unnoticeable due to their size and can be found on the leaves of plants.

An interesting fact about Thrips is, they bite humans accidentally. They probe the human skin with their mouth to check if it is their food or not, and when they realize it is not a plant they can eat, they fall off the body. Their bites may appear as rashes or lumps but, they do not inject anything inside the skin.

What are thrips? Where do they come from?

Thrips are tiny bugs that may be black or yellow, live on houseplants, and suck out the sap out of leaves, stems, and flowers. They can be seen under the leaves of infested houseplants but can be strenuous to see at first glance due to their miniature size.

There are about 6,000 known species of Thrips all around the world.

Adult thrips can fly so they can come in through open windows and doors when they detect the presence of a houseplant. As they are a common garden pest, they can come along with the cut flowers or plant parts that you may bring into the home from the garden.

Additionally, they can also come with plants that are purchased from stores.

Are thrips dangerous to humans?

No thrips are not considered dangerous to humans. For their feeding function, their mouthparts are specially adapted to pierce plants and suck out the sap.

But occasionally, when thrips land on human skin, they can break the skin surface but, they are not known to drink blood or inject anything into the bloodstream.

Thrip bites, therefore, are not dangerous to humans as they do not transmit any diseases to humans and animals. Bites from thrips may result in itching and forming some pinkish rash without any pain or swelling.

However, some people may experience smarting pain when bitten and severe skin irritation.

Additionally, people may go through raised lesions and blotchy rashes at the bitten area. The site of the bite may also turn reddish. People with bug bite allergies may go through severe reactions and should medical help as soon as possible after being bitten.

How to treat thrip bites?

In most cases, thrip bites do not require special treatment. They only result in mild irritations for some time and then go away. To reduce the itching, you can wash the bitten area with some warm soapy water.

However, if you face inflammation and itching, and rashes, visit a doctor as soon as possible. People with allergies to bug bites should seek medical attention right away.
