As a turkey hunter, I am keenly aware of the threat posed by sneaking through the Alabama woods. And I’m not talking about the danger of encountering a member of the serpent family.
I’m talking about something much, much smaller but possibly just as harmful.
It’s the family of ticks that turkey hunters dread each spring, and the prevalence of disease-carrying ticks is becoming more evident each year.
Emily Merritt, a research associate at Auburn University’s School of Forestry and Wildlife Sciences, has been working on a project since 2015 to determine the species of ticks in Alabama and their ranges.
Merritt said a study on ticks and tick-related illnesses hadn’t been done since the early 1990s, and it was very limited in scope. The study that started in 2015 was to update and expand that research to include field collection sites for ticks.
The most commonly collected ticks included the Lone Star tick, the Gulf Coast tick, the black-legged tick (aka deer tick) and the American dog tick.
The Lone Star tick is the most common tick in Alabama and can transmit a host of diseases, including the alpha-gal red meat allergy, Southern rash disease (a Lyme-like illness), tick paralysis and spotted fever diseases that are closely related to Rocky Mountain spotted fever.
“We found that the Lone Star tick and the Gulf Coast tick are the most aggressive,” Merritt says. The Lone Star tick is found primarily in hardwood stands, while the Gulf Coast tick, which is a little larger and transmits similar diseases, is found primarily in more open areas with shrubs.
The tick that has gained the most notoriety because of its association with Lyme disease is the black-legged tick.
“It is the main culprit for spreading Lyme disease, but it also can spread other illnesses, like anaplasmosis, ehrlichiosis and tularemia,” Merritt says. “We find black-legged ticks equally in pine and hardwood stands.”
Merritt said the American dog tick also can transmit all the diseases associated with the other tick species.
“As the name implies, they bite dogs a lot,” she says. “We find them in people’s backyards, especially if they’ve got a nice, green lawn and a nearby wooded area. Obviously, people’s dogs are at risk. If their kids play in the backyard or if you’re gardening or landscaping in the yard, people can come in contact with the American dog tick.”
Anglers, hunters respond
One aspect of Merritt’s research includes a survey conducted through the Alabama Department of Conservation and Natural Resources. The survey was sent to hunters and anglers to ask about their experiences, knowledge of and costs associated with ticks and tick-borne illnesses.
For those who spend time outdoors, Merritt said the project research found that the most effective deterrent for tick attachment is a spray that contains permethrin.
“You don’t apply it to your skin,” Merritt says. “You spray it on your clothes, boots, hats, socks, backpacks, basically any fabric. When I go camping, I spray my tents and tarps with it. Depending on what brand you get, it will last anywhere from two weeks or two washings to six weeks and six washings.
“More so than bug spray, we found that the products with permethrin significantly reduced the amount of ticks we encountered. It also works well on other biting insects like chiggers and mosquitoes.”
Although the likelihood of contact with ticks is higher during the warmer months, Merritt said the insects are active year-round in Alabama.
“Be on the lookout, not only on pets, but your children, your loved ones and yourself,” she says. “If you go outside, there is the potential to come in contact with ticks. When you come back inside, check your clothes and gear immediately to see if there are any crawling ticks on you, your pets or children. Then take it a step further and check your body thoroughly for ticks. If you need to use a mirror or a partner, do that. Ticks can hide in all sorts of areas that are hard to see.
“And the longer a tick is attached, the better the chances are to get a tick-borne illness if that tick is harboring that illness.”
Removing a tick
If you do find a tick attached to your body, Merritt said don’t haphazardly try to remove the insect.
“Don’t try to pick it off with your fingers or burn it off with a match or anything like that,” she says. “Get tweezers and get as close to the skin as you possibly can. Firmly grasp the tick where it attached to your body and start pulling with steady, even pressure until it eventually releases. It might be uncomfortable and a little painful, but you want to get that tick off as soon as you can.”
Merritt said tick-borne illnesses may cause symptoms as early as a couple of days, but symptoms could also occur as late as a couple of months after the exposure.
“If you start to experience flu-like symptoms, like aches and pain, or you see an expanding red rash, sometimes spotted and sometimes circular, you need to see a doctor,” she says. “It’s normal for a bite to be red, but if you see an expanding rash or it seems to be spreading to other parts of your body, that’s a clear indication that you do have a tick-borne illness.”
Merritt said if the tick is found it can be saved for testing by taping it to an index card, placing it in a freezer bag and storing it in the freezer.
“But don’t wait for test results,” she said. “If you think you have a tick-borne illness, your doctor should go ahead and start treatment. For most tick-borne illnesses, that involves treatment with antibiotics. For tick paralysis, it’s removal of the tick. For the alpha-gal allergy there is no treatment. You just have to avoid eating red meat, and that’s terrible.”
