How Do Bloodsuckers Find Hosts?
Most bloodsuckers have special carbon dioxide detectors that help them find hosts. Carbon dioxide is what animals exhale. So when a bloodsucker detects carbon dioxide in the air it knows that an animal with blood is nearby.
Ever notice how one minute there are no mosquitoes and the next minute it seems like there are millions of them all over you!!!!?? That’s because some types of mosquitoes can detect carbon dioxide from up to 200 feet away!
