Ticks are one of the few pests that are associated with lifelong medical issues. While a black widow spider may cause you intense pain and send you to the hospital for a bit, it is only for a night. Once the threat has passed, you can leave it behind you. When rodents invade your home, they can leave illness-causing pathogens until you finally call an exterminator and get rid of these pests. But, once they're gone, they're gone. When ticks bite, it isn't tormenting at all. In fact, you're not likely to even know that you've been bitten--and that isn't a good thing. Illnesses, like Lyme disease, can stay in your body for the rest of your life. And chronic symptoms of Lyme diseases are often mistaken for other serious illnesses such as fibromyalgia, multiple sclerosis, rheumatoid arthritis, ALS, Parkinson's disease, depression, and Alzheimer's. This is not a disease you want to have misdiagnosed.
