Relative sizes of several ticks at different life stages. Some tick species, like the brown dog tick, prefer to feed on the same host during all life stages.
This diagram shows the typical lifecycle of brown dog ticks. Brown dog ticks spread the bacteria that causes Rocky Mountain spotted fever in some parts of the southwestern United States and Mexico. Ticks can feed on mammals, birds, reptiles, and amphibians. Most ticks prefer to have a different host animal at each stage of their life, as shown below:.

Unfed larvae are able to survive for up to days, while unfed nymphs have been recorded to survive for up to days!
Even more impressive, unfed adult American dog ticks can go years up to 1, days without food! Adult female brown dog ticks lay 1,, tiny, dark brown eggs at a time. Once these eggs hatch into larvae, they can survive for up to eight months without food or water. In the nymph stage of their lifespan, brown dog ticks can go three months without attaching to a host.
Adult brown dog ticks typically attach to a dog to feed as soon as possible, but they can survive for up to 18 months without feeding! Female lone star ticks lay an average of 3, — 5, eggs at a time. Once hatched, these larvae can go without a host for up to days. Once lone star ticks mature from larvae to nymph, they can go over a year — up to days — without feeding, and fully mature adult lone star ticks can go without a blood meal for up to days!
Similar to the lone star tick, Rocky Mountain wood ticks lay around 3,, eggs at a time on average. The eggs hatch in anywhere from days, and once they do, the larvae typically attach to any nearby host. They usually need to find a host within 30 days, but some can go up to days without attaching! Once there, they latch on and begin to feed. If left undisturbed, ticks can feed on humans for several days. Ticks feed on cats and dogs in the same way they feed on humans.
Reports of how long ticks can survive without a host vary widely, but some studies have suggested that they can live for up to 18 weeks without food! They will usually die within 24 hours on dry clothing and days on wet clothing. Can ticks live indoors and, if so, for how long? For example, blacklegged ticks like lots of humidity, and typically hang out in areas with dense vegetation like forests.
Therefore, they are unlikely to survive for more than 24 hours in your house. Other species like the lone star tick and the American dog tick can survive in a wide variety of habitats and love warm, dry areas. These species could happily live out their entire life cycle in your house. The dry environment inside your car can be a death-trap for ticks as some species, like the blacklegged tick, need moisture to survive.
