The simple answer is no fleas do not fly. I’m so glad they don’t fly to because if they did we would be covered in a whole lot more bites and have a much harder time getting fleas off our pets and out of our home.
Instead of flying fleas use their incredibly powerful hind legs to propel themselves from place to place or from host to host. This makes it much easier for them to feed off a host than if they were to just crawl around on the ground. Their hind legs can launch them between 4 and 5 feet into the air making it pretty easy to get around!
If fleas were human sized athletes participating in the long jump in the Olympics, certain fleas could break the current world record by approximately 970 feet.
