How Are Fleas Attracted to Humans?
WouterFleas are attracted to human skin by carbon dioxide, which is produced by warm-blooded animals, and they prefer warm temperatures. The warmth is necessary for the fleas to function properly. Fleas have flattened bodies and are able to maneuver in many materials. They prefer warm bodies, but they are also attracted to certain types of movement. In addition to humans, fleas are attracted to tall grass and wooded areas, as they provide a good hiding place for the fleas. Yard clutter and watering spots are also good lures for fleas, so it is important to remove them from your property.
Fleas are attracted to certain types of human skin, which may be due to different chemical compositions and different skin secretions. Some fleas may also transmit a signal to other fleas to alert them to a new warm-blooded meal. Consequently, if you have allergies to flea saliva, you may see an increase in flea bites.
Fleas may also be attracted to certain scents, such as human sweat. They might prefer particular people because they have a scent that is similar to their own. Some fleas may also be attracted to certain foods or products you use on your skin. Some foods that repel fleas are garlic, onions, and curry. In addition, some plants have volatile compounds which help repel fleas.
