Are aphids harmful?

Do aphids bother humans?
Aphids (Aphis spp.) do not bite human beings or chew plant leaves. Instead, these small, soft-bodied insects insert microscopically thin, piercing mouthparts into plant leaf and stem phloem and feed off of sugar-rich plant juices. The saliva prevents wound healing, causing leaves to curl and become distorted.
Do aphids make humans itch?
The result of being ‘bitten’ by the aphid is a red swelling that disappears after an hour or so, but leaves a very itchy rash that can persist for two to three days. In fact this phenomenon is so common that people avoid passing underneath infested trees.
