Experts disagree about how long it takes a tick to transmit Lyme disease. The CDC says that in most cases, the tick must be attached more than 24 hours. We think that gives people a false sense of security. In some research studies, 5-7% of nymphs transmitted the Lyme bacteria in less than 24 hours. One paper reported on a case of Lyme disease tran...
Researchers have found spirochetes in mosquitoes and other blood-sucking insects. But it has not been proven that they can transmit the infection. A tick is uniquely suited to carry and spread Lyme disease. Spirochetes have co-evolved with ticks over millions of years. Tick saliva contains immune suppressors that help disseminate the bacteria throu...
Nymphal ticks cause most cases of Lyme disease. Because nymphs are as small as poppy seeds and their bite is painless, people often don’t realize they have been bitten. Adult ticks can also infect humans, but are easier to spot and remove. Not all ticks are infected. Because tick studies have only been done in a relatively few places, in most of th...
Adult ticks feed and mate primarily on deer. You may also find adult ticks on dogs, horses and other domesticated animals. Nymphs feed primarily on smaller animals. These include squirrels, mice, lizards, rabbits, and birds that feed on the ground. Migratory birds help distribute ticks throughout the country.
A multitude of environmental and human factors has created a near “perfect storm” over the past 20 years leading to a population explosion of ticks throughout North America. Learn more about the types of ticks.

Babesiosis. Colorado tick fever. Powassan encephalitis. Tularemia. Ehrlichiosis. Relapsing fever. Who is at risk for Lyme disease? Factors that can increase your risk for getting Lyme disease include: Working or spending time outdoors in areas where the black-legged deer tick or Western black-legged deer tick is found.
Lyme disease is most frequently reported from the upper midwestern, northeastern, and mid-Atlantic states where it is spread by Ixodes scapularis ticks. Some cases are also reported from northern California, Oregon, and Washington, where it is spread by Ixodes pacificus ticks.
Nov 15, 2011 · Top of Page. How ticks spread disease. The tick feeding process makes ticks very good at transmitting infection: Depending on the tick species and its stage of life, preparing to feed can take from 10 minutes to 2 hours. When the tick finds a feeding spot, it grasps the skin and cuts into the surface. The tick then inserts its feeding tube.
