Usually we post blog entries about preventing accidents and safety issues. But here is something that is a serious matter of public health, and we want you to protect yourself!

The incidence of tick-borne illnesses is rising sharply in Massachusetts, in New England, and throughout the country. If not diagnosed and treated promptly, infections can lead to disabling injuries, brain damage, organ failure, and even death. Prompt diagnosis is key, but even more important: Avoiding tick bites.

Understanding tick behavior is the first line of defense. Ticks are active throughout the warm weather months, but even a warm day in February can bring them out. They are most likely to transmit disease in the spring and early summer when they are in their nymph stage (when they are young and smaller). Ticks lurk in leaf litter, tall grass, and on shrubbery, just waiting to hitch a ride on your skin and clothing. Then they wander around until they find a place to bite. They will attach themselves and suck your blood until they are fully engorged. And if they are carrying one of the many bacteria that can make you ill, it will be transmitted during this time.

There are several ways to protect yourself, including wearing insect repellent or clothing treated with permethrin, an effective insecticide that is safe to use. Prevent ticks from getting on your skin by wearing long pants and long shirts, and stay tucked in. Check for ticks after you have been outside. More on this below.

Tick Diseases are on the Rise

It’s unfortunate that we have to think about protecting against ticks. But it’s also necessary. Each summer brings more and more reports of tick-borne illnesses in Massachusetts and across the U.S. According to the Centers for Disease Control and Prevention (CDC), 59,000 tick-borne diseases were reported during 2017 alone, more than 10,000 cases over 2016. More than 42,000 cases were Lyme Disease. According to the CDC, the number of U.S. counties considered at high-risk for Lyme Disease increased by more than 300 percent between 1992 and 2012.

Lyme Disease and Other Tick Diseases in Massachusetts

In Massachusetts, several types of ticks are known to spread infection. These include the black-legged tick, most often known as the deer tick, the dog tick and the lone star tick (Source: 

Black-legged ticks can transmit Lyme disease, anaplasmosis (HGA), babesiosis and other tick-borne illnesses. These are all very serious illnesses which can leave an otherwise healthy person with chronic pain, an irregular heart rhythm and other symptoms. Some of these illnesses can even lead to death. 

While we associate ticks with warm weather, black-legged ticks can bite year-round in Massachusetts. The young ticks (called nymphs) are most active during May, June and July. Adult ticks become more active during the spring and fall, but can bite anytime the temperature is above freezing. It’s easy to mistake nymphs for other insects because they are small, about the size of a poppy seed.

When black-legged ticks infect someone with Lyme Disease, the person may suffer fever, chills, headache, fatigue, muscles and joint pain and swollen lymph nodes. About 4 out of 5 people will break out in a rash which is often a bullseye in appearance. In some cases, more serious symptoms emerge, including arthritis, heart palpitations, joint pain, nerve pain and problems with short-term memory.

Adult dog ticks are roughly the size of a watermelon seed and can spread Rocky Mountain spotted fever, which can lead to fever, headache, vomiting and rash in the first 3 to 5 days. Rocky Mountain spotted fever can result in death if left untreated.

Though it’s relatively rare in Massachusetts, dog ticks can also pass on certain types of tularemia, which results in skin sores and swollen glands. As for lone star ticks, it is important to guard against them because they can also cause rash, tularemia and southern tick-associated rash illness (STARI). But lone star ticks are not a significant source of human illness in Massachusetts at this time, according to the state website.

How to Protect Your Family

The best ways to protect yourself from tick bites and tick-borne illnesses is to be aware of potential exposure in the deep woods and tall grass, wear the right insect repellent and continuously check your skin throughout the day and at the end of the day.

Insect Repellent

  • Use EPA-registered insect repellents which contain DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol, or 2-undecanone. Use these products as instructed.
  • Use insect repellent products with permethrin to treat clothing, socks, boots and tents. You can also look for products which have been pre-treated with permethrin. Follow the instructions for application carefully. Permethrin is applied to clothing, then allowed to fully dry. It is not meant to be sprayed on just before use. Treated clothing is effective for several washings. The good news is that the ticks that do climb on your treated clothing will die.
  • Take extra caution when shopping for insect repellent products for children and those with medical conditions. Again, read product instructions.
  • Children younger than 2 months old should never use products containing DEET. The CDC recommends putting babies in strollers covered in mosquito netting.

Understand How Ticks Infect

Ticks can contract bloodborne infections such as Lyme Disease by feeding on infected animals, especially white-footed mice. Then they carry these infections into your backyard and wait for their next prey. This could be you, your children, your guests or your pets.

Unlike other insects, ticks cannot fly or jump. They latch onto tall grass with their back legs, ready to climb on you when you pass by. This is called “questing.”

A black-legged tick can attach to your skin and feed on your blood for several days. Once the tick is done feeding, it will remove itself and find another person or animal to bite.

Avoid tall grass and shrubs, as well as the outer edge of your backyard. Ticks often camp out along well-traveled paths on your property, including near stony landscaping. Wherever you walk or hike this summer, walk in the center of the path.

The sooner you see a tick on your body and remove it, the better. According to the CDC, people who remove ticks within 24 hours can greatly reduce their risk of getting Lyme Disease.


Cats and dogs can bring ticks into your home. Talk to your veterinarian about how to protect your pets during the summer months. There is no evidence showing your pet can pass Lyme Disease onto you, but if your pet is bitten, they could suffer symptoms and you could be bitten as well. Since ticks can be carried into your home, be aware of exposure in your house.

Dressing Safely for the Outdoors

  • Dress appropriately. Wear long-sleeves and pants when working in wooded areas. Tuck shirts into pants and pants into boots.
  • Consider wearing white and other light colors if it helps you check for ticks easier.
  • Another tip is you can use a lint roller on your clothes and shoes before you come inside.
  • Take a shower as soon as you come inside. Rinsing ticks off before they bite is very effective.
  • Toss your clothes in the dryer on high heat for 10 minutes to kill ticks.

Checking for Ticks and Extra Precautions

  • Conduct a full-body tick check once or more daily. Use a hand-held or full-length mirror so you can check your back and other areas of your body. Check along your hairline, inside and behind your ears, the back of your neck, all over your arms and armpits, legs, behind your knees and even between your toes.
  • Parents should check children thoroughly for ticks every few hours. Teach children to regularly check their own arms and legs as they play.
  • Look closely and remember, ticks are different sizes.
  • If you see a tick, carefully remove it from your skin with a pair of tweezers. Pull it out with a steady hand so you remove it all at once. Then clean your skin with rubbing alcohol or soap and water.
  • You should dispose of a tick just as you would anything else that’s poisonous. Place it in a sealed plastic bag or flush it down the toilet. If you are concerned that the tick was on you long enough to bite, you can seal the tick in a plastic bag for later testing.

Visit Your Physician and Get Prompt Treatment

There is a high risk for Lyme Disease in Massachusetts and other New England states. If you, your child or another family member were bitten by a tick, contact your physician immediately. Even if you don’t believe you are experiencing any symptoms, this is an important call to make. Your physician is knowledgeable about your medical background and the medications you are on and is in the best position to help you understand if you may need to take an antibiotic. If exposure to Lyme disease is considered a probability, your physician will likely prescribe a single dose of doxycycline as a prophylactic measure. It is very important to monitor yourself for symptoms of potential infection, including rash, headache, muscle or joint ache, or fever. If you are suspicious, seek prompt treatment to avoid more serious complications.

Use Reasonable Care and Good Sense

Don’t let the fear of ticks or other insects ruin a perfectly good summer. Use reasonable care and good sense, and you and your family should enjoy great outdoor fun.
