Word on the street is: It’s going to be way too easy to catch Lyme disease this year. That’s because it’s a boom year for black-legged ticks (also called deer ticks) and a bust year for their preferred blood host, white-footed mice. Since mice are scarce the ticks will look for other hosts including us and our pets.
Lyme disease is caused by a bacteria (Borrelia burgdorferi) transmitted by the bite of a black-legged tick. Black-legged ticks must have a blood meal in order to transition to their next life stage. Any tick that’s acquired the bacteria from a prior host will give the bacteria to its next host.
The nymph stage is the most dangerous to humans because it is so hard to see. It’s a critter the size of a poppy seed that has all the time in the world to walk up your body in search of a sneaky place to latch on and suck your blood. If it bites you for more than 24 hours you have a higher chance of getting Lyme disease.
You never, ever want to get Lyme disease. As my friend Dick Martin says: “About a week after the infection, you will be hit by instant old-age. Aches, flu-like symptoms, etc. are bad. I speak from experience.” The disease is debilitating with life-long effects if you don’t catch it early.
It’s way too easy to get ticks. Any one of these activities will do it:
- Visit infested areas (notice red X’s at this link). Interestingly, the infection zones for Pennsylvania are more widespread than the tick infestation map.
- Sit down on anything other than pavement or furniture.
- Walk off trail near a stream, seep or wet zone.
- Allow grass or plants to brush against you.
So you shouldn’t go outdoors? Wrong! Your best defense is vigilance:
- Wear light-colored clothing that covers your skin — long pants and a long-sleeved shirt with collar. Pull your socks over your pant cuffs. I can tell you this outfit is eccentric and stifling in hot weather but it’s worth it.
- Spray your clothing with bug repellent, especially your boots, socks, pants.
- Check for ticks. Check your clothing while you’re in the woods. (That’s why you wear light colors.) Check before you get in your car. Check your body and scalp (take a shower).
- Remove ticks with precision tweezers.
- Know Lyme disease symptoms and get treatment early. Dick Martin says, “Don’t count on the bull’s-eye red rash; I skipped that indicator. If you pick off a blood-filled tick, ask your doctor for a prophylactic dose of an approved medication. If you hesitate for the week, you have a tougher regimen of medication. If you somehow ignore that, you have more serious, long-lasting effects.”

Hawaii is the only state where Lyme disease has never been reported. Plan accordingly.
