The Female tick lays hundreds and hundreds of eggs in the leaf litter. She slowly responds to environmental changes.

Ticks perch on vegetation waiting to sense an animal host. Haller’s organs and sensilla receptors on their legs detect air-borne frequencies and CO2. Receptors can detect biotremologic substrate vibrations caused by animal movements. A host approaches.

The mouse sustains the lifecycle of the Borrelia spirochettes. An immature tick is attached to it's paper-thin ear. The Borrellia spirochetes reside in the mouse bloodstream and transfer to the tick through the thin ear vein.

The deer runs, with CO2 exhalations travel across its back. The female tick embeds and takes a blood meal. While it feeds, the male tick slips under her. They mate.

Borrelia spirochetes go through alterations and multiply in the tick gut. They travel to the tick salivary glands and into the host.

Humans can enter the cycle resulting in illness. The spirochetes can penetrate human skin barriers and travel to the organs including the heart, the joints and the neural pathways to the brain.
