How Big Can Mosquitoes Bite Get?

Generally, mosquitoes are very small insects, less than two centimeters across. When they bite, they release saliva, which causes itching and swelling. The saliva contains proteins that are allergens. Itching and swelling can be relieved by applying an antihistamine cream.

The itch from a mosquito bite may persist for up to three days. After three days, the swelling will be less. If the swelling persists for more than two days, see a doctor. The doctor may prescribe an antibiotic ointment to apply on the bite.

Some people have a severe allergic reaction to mosquitoes. This reaction can lead to swelling in the mouth, throat and lips. Other symptoms include wheezing, joint swelling, nausea and vomiting. A severe reaction can also be accompanied by anaphylactic shock. If you have a severe reaction to a mosquito bite, see a doctor right away.

There are two types of mosquitoes. The female mosquitoes lay eggs in standing water. They also pierce the skin with a special mouthpart. These bites are itchy and red. The female mosquitoes then hatch into pupae, which live for several weeks.

If you have a severe allergic reaction to a mosquito bite, it is important to seek medical treatment. A doctor may prescribe antihistamines such as Allegra or Zyrtec. Oral antihistamines are also available. The doctor can also recommend effective ways to avoid mosquito bites.

If you have a mosquito bite, avoid scratching. Scratching can make the bite itch more and can cause scars. If you need to scratch, use a blunt object to press down on the bite for ten seconds.
