They are a common summer nuisance. Mosquitoes are pesky parasites leaving bite marks that can be unbearable. So what’s the best way to stop yourself from scratching?

Jason Howland has the answer from a Mayo Clinic expert.

There are millions of mosquitoes swarming this summer, sucking blood and leaving itchy, red bumps on the skin.

“Their saliva deposits in the skin from where the bite is, and it’s causing a reaction to that saliva,” said Dr. Summer Allen, a Mayo Clinic family physician.

Allen said some of the tried-and-true home remedies for treating mosquito bites work well. Calamine lotion, over-the-counter hydrocortisone cream and even a cold compress can ease the itch.

“It’s going to sooth and kind of calm down that intense burning and inflammation that they’re feeling in their skin,” said Allen.

And, while it’s not always easy, it’s important to keep the scratching to a minimum.

“If they scratch it hard enough, or depending on what they use to scratch their skin, they can cause a break in their skin,” said Allen. “They can develop a bacterial infection.”

Although using insect repellent and other prevention tips can reduce your chances of being bit, really, getting at least one skeeter bite this summer is almost inevitable.

“Time takes care of it, and try to do your best not to scratch it if you can,” says Allen.
