What bugs cause red itchy welts on skin?

There are many types of bugs that cause red itchy welts on skin. Some of the most common include:

- Mosquitoes: Mosquitoes are small flying insects that feed on blood. They use their long proboscis to pierce the skin and suck blood. Mosquito bites can cause red itchy welts that can last for several days.

- Fleas: Fleas are small, wingless insects that live on the fur of animals. They can jump and bite humans, causing red itchy welts. Flea bites are often found in clusters and can be very uncomfortable.

- Bed bugs: Bed bugs are small, parasitic insects that feed on blood. They live in cracks and crevices in furniture and bedding. Bed bug bites can cause red itchy welts that can last for several weeks.

- Ticks: Ticks are small, blood-sucking parasites that live in grassy or wooded areas. They attach to the skin and feed on blood. Tick bites can cause red itchy welts and can also transmit diseases such as Lyme disease.

- Fire ants: Fire ants are small, aggressive ants that are native to the southern United States. They have a painful sting that can cause red itchy welts. Fire ant stings can also lead to serious medical problems in some people.

If you experience red itchy welts on skin, it is important to see a doctor to determine the cause and get treatment. In some cases, bug bites can be treated with over-the-counter medications. However, in other cases, more serious medical treatment may be necessary.
