1. Lyme Disease is Caused by Black-Legged Ticks
Lyme disease is caused by Borrelia bacteria. Black-legged ticks bite infected deer, birds or rodents, then transmit the bacteria to humans and pets.
Adult ticks are about the size of a sesame seed, which makes them difficult to spot. In order to get Lyme disease in the first place, you must be bitten by an infected tick that remains attached to your skin for at least 16 to 18 hours to push the bacteria into your bloodstream.
