I recently had a question asking if other bugs besides ticks can spread Lyme Disease. Here is the answer.
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 throughout the host’s body. And, because ticks feed on many different animals, they can spread the disease widely.
