I just heard this about Insect Bites. Here's a great home remedy:

Meat tenderizer: An insect bite can be treated with meat tenderizer to stop the itching. It is made into a solution with water and gently dabbed on the bite to relieve the itch. For particularly itchy bites, a paste may be more effective. Be careful not to take the top off the bite when applying, as that could increase the likelihood of infections.


Hope this helps!
