Victor asks for tips in dealing with pests and other natives of the Appalachian Trail, such as Ticks, Flies, Mice, Poison Oak, Poison Ivy, and any others not on his radar. I’m going to break his question up in parts.
VM: Do you have any useful hints for removing ticks? Is it true a drop of turpentine will make the ticks dig themselves out?
RG: Good question. Ticks are the worst. I'd honestly rather see a black bear on the trail (actually I love seeing black bears, so that's a bad example). I only saw two ticks crawling on me while hiking the AT, but I also met two hikers who contracted Lyme Disease, so it's good to know a few things about them before heading out.
There are several myths about tick prevention and removal. Using heat or covering the tick with anything in order to coax it back out can only make the problem worse. It can actually cause them to regurgitate more saliva (and potentially more pathogens) into your bloodstream.
The hypostome, i.e. mouth parts, that they burrow into your skin, looks similar to a tiny barbed harpoon. Also, some ticks, like the Lyme-Disease-spreading deer tick, secrete a cement-like substance to keep themselves securely attached to your skin while feeding. In other words, they can't back out quickly even if they wanted to. The longer the tick is attached, the higher your risk of infection, so the goal is to remove the tick as soon as possible.
The best way to remove a tick
The best way is with tweezers. Some ticks, like the Deer Tick, can be as tiny as a poppy seed, so you’ll need tweezers that can grab something that small. Grab the tick as close to your skin as possible and slowly pull it straight out. Clean the skin around the bite with alcohol. If the hypostome (mouthparts) remain stuck in your skin, don’t worry about it. Doctors aren't concerned about it, so I'm not either. Also, when the hypostome breaks it may even send germs and saliva further back into the ticks body and saliva glands.
Lyme Disease
The biggest concern with ticks on the Appalachian Trail is Lyme Disease. There are 30,000 to 40,000 cases in the United States annually and about three out of four are reported in ten of the states along the Appalachian Trail.
Here they are in order of highest cases per capita: Vermont, New Hampshire, Maine, Connecticut, New Jersey, Pennsylvania, Massachusetts, Maryland, New York, and Virginia.
If you experience any symptoms like a rash or fever, consult your doctor and let them know you've been bitten.
Signs of Lyme Disease
Check out the Centers for Disease Control's web site for more information, but I'll give you a summary. One of the first signs that you have contracted Lyme Disease, which will normally occur 1 to 2 weeks after infection, is the development of a bullseye-shaped rash around the bite, although sometimes there won't be a rash at all. Lack of energy is another common first symptom, but you'll feel that on your hike either way. Other symptoms include fever, chills, headache, stiff neck, swollen lymph nodes, muscle pain, and joint pain.
If you do have symptoms, see a doctor as soon as possible. The longer you go without treatment, the worse symptoms will get and it can get incredibly nasty. If you find a bullseye-shaped rash or feel symptoms of the flu, get checked. If you do pull a tick off your body save it in a Ziploc bag so it can be tested later if symptoms do appear.
Preventing Ticks
Chances are you'll hike the entire Appalachian Trail without having a tick burrow into you, but with a few precautions, you can reduce your risk of getting Lyme Disease to nearly zero.
Do a daily tick check
Full disclosure, the longer I went without seeing a tick the less frequently I would do a tick check. Eventually, I only checked after hiking through bushy areas with tall grass or loose dry leaves on the ground. My laziness aside, daily checks are by far the best way to prevent the spread of Lyme Disease. It generally takes at least 24-48 hours for a tick to transmit the disease, so if you're doing daily checks, it's unlikely you'll get it.
Thorough tick checks are important since their saliva has anesthetic properties. That means you won't feel them burrowing or feeding. Additionally, they are hard to find because some, like the deer tick, are as small as a fleck of dirt, which you'll be covered in most of the time. They also have a tendency to search for places on your body that are hard to see without a mirror... and places your friends will not volunteer to check for you.
Bug Repellent
I'll go into this deeper below, but DEET is still the most effective bug repellent. Nothing really comes close in effectiveness, duration of effectiveness, and cost per ounce. There are a lot of home remedy bug repellent myths out there, but none have been shown to be effective for more than a few minutes, if effective at all. Don't waste your time or risk going without an effective treatment. A 23 to 33% DEET solution is the way to go and it's safe if used properly.
Wear Light Colored Clothing
Even though I didn't have any biting ticks on the Appalachian Trail, I did find a couple crawling on my pant legs. It happened after scouring the woods for firewood in Shenandoah National Park. Since I wore light brown khaki pants they were easy to spot.
Walk in the Center of Trails
Those minuscule SOBs are hanging onto plants with their little legs outstretched waiting for a blood-filled mammal to walk by. Avoid their reach by walking down the center of the trail whenever possible.
Some Months Are Worse Than Others
Peak tick season starts in late-April to early-May and lasts all through summer. That doesn't mean you won’t get ticks on you in October, though. Actually, that's when I found them on me in Shenandoah. In other words, they are going to be around during your entire hike, but they will probably be worse Late-May through Early-August.
