Off to Google I went to find some DIY home remedies. Perfect! I found several things that may help and (bonus!) I have at home.
First off, I read fresh basil can stop the itching. Awesome! I have two pots of basil outside. I went and pulled several leaves and used one leaf and rubbed it directly to the mosquito bite on my leg. Prior to this, I was scratching like crazy and yes, I know, not a smart thing to do because it would aggravate it even more. So I rubbed it on my leg for about five minutes and voila! It works! The slight swelling and redness was still there, but the itchiness stopped...for now.
Other things I have in my home already and you may have too are:
Apple cider vinegar has so many helpful benefits. I use it as a facial toner. It does smell like a stinky sock even after it dries because I can smell it on myself. I dilute it with water. Usually I use one part apple cider vinegar and three parts filtered water. To use on mosquito or insect bites, you can use it directly. Put some on a cotton ball or use a Q-Tip and apply to the bite. This I will say works better than the basil.
I didn't try these...
Milk mixed with water and apply to the bite can also relieve the itchiness.
Make a paste with baking soda and water
Crush an aspirin, mix with water to make a paste
If you have an aloe vera plant, open one leaf and use the gel directly on the bite. To soothe and get a cooling effect, put a leaf in the fridge.
Choose an essential oil such as lavender oil, tea tree oil, cedar oil, or witch hazel. All of these have anti-inflammatory properties to help reduce swelling and pain. A bit goes a long way, so just a dab will do.
