Even though bed bug bites don’t usually transmit diseases, they can cause a lot of itching and irritation. But why do bed bug bites itch?

There are several reasons why bed bug bites might itch. One reason is that when the bugs bite, they inject saliva into your skin. This saliva can cause allergic reactions in some people, which leads to itching.
