Are you one of those lucky individuals who seem to be a magnet for mosquitoes? Or do you always remain unscathed while your friends are covered in bites? The answer might lie in your blood type.

Unlike flies that bother humans for various reasons, mosquitoes target people with one sole purpose: to get their blood. These cunning insects pierce and suck blood before you even realize you’ve been bitten.

So, you might wonder, why are you always suffering from itching, swelling, and redness on your body? Especially if your family and friends seem to be immune to this constant annoyance.

The answer could be related to your blood type. According to, researchers have been studying patterns and behaviors of mosquitoes since the 1970s in search of an explanation for why mosquitoes bite some people more than others.

Research studies indicate that mosquitoes have a preferred blood type that makes them favor certain individuals: type O. If you have this blood type, it might be the answer to why you often find yourself being pursued by mosquitoes.

Why do mosquitoes love this blood type? Several studies have shown that the proteins in blood type O attract the hungry mosquitoes more than other blood types. These little bloodsuckers will also attack individuals with blood type B, but not as aggressively as they chase those with blood type O.

Blood type A is the least preferred by mosquitoes, meaning if a person with blood type A is hanging out with friends of blood type O or B, the hungry mosquitoes might go straight for them and completely ignore individuals with blood type A.

If you’ve found that you’re always being attacked by mosquitoes while your friends escape unbothered, this could be the reason. However, it’s not always a consistent rule.
