In each stage after hatching, they suck blood from animals like mice, squirrels, birds and deer. Then they drop off, enter a dormant period and molt to enter the next stage. They get it by feeding on an infected animal, often a mouse or other small rodent. Then, they pass it along to the next animal or person they bite. 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. One paper reported on a case of Lyme disease transmitted after six hours of tick attachment.
The longer a tick stays on you, the more likely it will transmit disease. 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. And, because ticks feed on many different animals, they can spread the disease widely.
They have a four-stage life cycle—which includes egg, larva, nymph, and adult. Ticks in this stage have not been shown to transmit tick-borne illnesses. Ticks in the nymph stage are the most active in late spring and summer and are the main cause of Lyme disease infections. An adult tick has a flat shape and is about the size of a sesame seed. Because of their small size, they can be tough to find.
Most adult ticks who carry Lyme disease will feed on animals like deers, dogs, horses, and other domestic animals. Ticks that carry Lyme disease are active year-round.
However, their peak season of activity is from April to September, though they can survive in below-freezing temperatures, as well. During peak time, the tick nymph actively seeks a host and its bite is associated with the greatest risk of Lyme bacteria transmission. Lyme disease ticks can be found in leaf litter, woodpiles, stone walls, tall grass, beach grass, bushy areas, areas planted with ground covers, and lawn edges that meet forests, woodlots, and gardens.
Essentially, Lyme disease ticks can be found anywhere their hosts live, though they tend to prefer moist and shady areas. The deer tick is infected by vertebrate animals like white-footed mice, chipmunks, shrews, ground-feeding birds, and other small mammals that have Lyme disease bacteria themselves. Have you been bitten by a tick?
Firelands Virtual Care. A black-legged tick AKA deer tick , the kind that sometimes carries Lyme disease, was spotted just to the east of us in Vermilion earlier this summer. And Ohio is on the list of 24 states that contains counties with newly documented populations of deer ticks. Tick bites are common. Some people are unaware of a tick bite at first. Be sure to check yourself and your children often, especially throughout the summer months when tick populations grow.
Ticks are especially attracted to warm, moist areas of the skin like armpits, groins, or hair. Once they bite you, a tick may stick around drawing your blood for up to 10 days. The sooner you spot and remove a tick, the better. Instructions for Completing Audit Tools. Position Statements and Practice Recommendations. Canadian Journal of Infection Control.

The best way to prevent infection is to avoid tick-infested areas whenever possible, particularly in spring and early summer when nymph ticks feed. Adult ticks are a bigger threat in fall.
