Many people are surprised to learn that only female mosquitos bite animals and humans.
Female mosquitoes bite because animal blood provides the perfect package of nutrients necessary for their developing eggs. Basically, our blood is the perfect mosquito prenatal supplement.
Female mosquitoes use an organ called a maxillary palp to detect carbon dioxide that animals and humans emit while exhaling. They can also pick up on thermal cues like our body temperature, and even certain scents we emit, making them a relentless predator.
