Ticks in Florida
Tick Life Cycle
General tick life cycle (may vary depending on tick species)
Most people are infected by nymphal stages during the spring and summer. Nymphs are often small enough to escape notice and so can stay attached longer than adults, increasing risk of disease transmission.
- Blacklegged Tick
- Lone Star Tick
- American Dog Tick
- Gulf Coast Tick
- Bont Tick *Not from florida, may be brought in from the Caribbean*
- Argasid Tick ("Soft Tick")
April-August: Larvae and Nymphs
Larvae and Nymphs: Reptiles (skinks and snakes), birds, and some rodents
Adults: Larger animals including cattle and humans
Lyme Disease, Babesiosis
Adults: April-August (peak in July)
Larvae and Nymphs: Small mammals and birds, do not feed on rodents
Adults: Deer, cattle, and humans
Larvae and Nymphs: Almost exclusively small rodents, particularly mice and cotton rats

Rocky Mountain Spotted Fever
Larvae and Nymphs: Small rodents and ground dwelling birds
