Why Do Bug Bites Itch?

The video explains that bug bites themselves don't itch; it's the body's allergic reaction to mosquito saliva that causes itching. Some insects, like certain ants, have venom that can irritate the skin. Mosquitoes use a complex proboscis to extract blood and inject saliva, which contains anticoagulants and can transmit diseases. The body's histamine response to the saliva causes the itching and swelling associated with bug bites.
