- Most bug bites and stings heal on their own in a few days.
- You can lessen your chance of diseases transmitted by mosquitoes by wearing long sleeve shirts, long pants, and using insect repellant with DEET while outside.
- Allergic reactions include trouble breathing, trouble swallowing, swelling of lips, tongue, or face is serious and requires medical attention right away.
General Info & How to Protect Yourself:
Bug bites and stings are common, especially in the summer. Usually, a bite or sting from an insect is harmless and will heal on its own. Rarely, a bug bite or sting can cause an infection or an allergic reaction that needs medical attention right away. Certain kinds of ticks and mosquitoes however, can transmit serious illnesses such as Lyme disease, Eastern Equine Encephalitis (EEE), West Nile Virus, Chikungunya, Yellow Fever, Malaria, and Zika, depending on where you live or travel.
The best way to protect yourself from bug bites and stings is to avoid places where bugs are likely to be or wear long sleeves and long pants and insect repellant.
Here are some tips when you are planning to be outside:
- Wear clean light colored clothing: long sleeve shirts, long pants, socks and shoes.
- Try not to wear bright or flower print clothing when you’re outside near stinging bugs. They may think you’re a flower!
- Use an insect repellant that contains 10%-30% of DEET. It may be listed on the product label as N, N-diethyl-m-toluamide. Products with DEET protect against mosquitos, ticks, and some other bugs.
- Don’t apply insect repellant directly to your face. Spray a small amount on your hands then gently rub it on your face and neck. Be careful not to touch your eyes and mouth.
- Don’t use combination sunscreen and DEET products, because sunscreen should be reapplied but DEET should not.
- Avoid using perfume or scented hair products, lotion or deodorant products.
- Be careful when eating sweets or drinking out of soda cans while outside (bees and wasps often fly into soda cans then sting a person when they take a sip) – Keep drinks covered.
- Avoid areas with puddles of still water as mosquitoes lay their eggs there.
- Be aware that mosquitos multiply in standing water, which is water left in wading pools or buckets. It’s best to drain any standing water to lessen this from happening.
- Don’t harm bee, wasp or ant nests.
- If you a driving a car and notice a bug inside, pull over to a safe place and open all the windows until the bug flies out.
- If you’ve had an allergic reaction in the past to an insect bite or sting, you should ALWAYS carry an epinephrine autoinjector such as EpiPen®.
Did you know that most mosquitoes are more active as the sun goes down and again during sunrise? You can lower your risk of being bitten by planning outdoor activities in the early afternoon, but wear sunscreen to avoid damage to your skin.
Bee and/or Wasp stings
Most often bee/wasp stings cause a minor discomfort and can be treated at home. However, if you have an allergy to bee or wasps or you get many stings all at once, you will likely need medical care right away. A mild reaction typically feels like a sharp, burning pain where you are stung. The area usually turns pink or red and swells up or looks puffy. The swelling usually goes away within a couple of hours. A moderate reaction is happens when the sting or bite looks very red and the swelling gets worse over the next few days. Let your health care provider know if you get this type of reaction. Severe reactions to a bee sting or other bug can be dangerous and even life threatening (anaphylaxis), requiring emergency treatment. Symptoms of anaphylaxis includes swelling of your tongue and/or throat, rapid pulse, trouble breathing, severe itchiness, flushed or pale skin. Stings are usually painful at first but feel better quickly.
Bees often leave behind a stinger. Try to take it out of your skin as quickly as possible. You can use a clean pair of tweezers to pinch the stinger or you can use the side of a plastic credit card to flick it off your body. Wasps don’t leave stingers.
- Wash your sting with soap and water and pat dry.
- Put an ice pack or a cold, damp washcloth on the sting for 15-20 minutes.
- Apply a small amount of anti-itch cream if needed
- Don’t scratch the sting or bug bite as this may cause infection.
- Watch the area for the next several days for any sign of infection (redness, swelling, pus, pain)
Most of the time bee/wasp stings are not serious unless a person has an allergic reaction or if the bite becomes infected. Symptoms of an allergic reaction include a rash or “hives”; swelling of the lips; tongue or face; dizziness or fainting; trouble breathing. If any of these symptoms occur, it’s important to call 9-1-1 and get help right away!
Spiders usually don’t bite, but if they do, it can be painful. For those who have an allergy to spiders, a bite from a spider can be very dangerous. There are just a couple of spiders that are found in the United States that are poisonous. These are the black widow and the brown recluse spiders. When they bite, they inject “venom” (small amount of poisonous liquid) under the skin.
A reaction to a common spider bite is similar to other insects. Symptoms typically include redness, pain, and swelling at the site. A scab usually forms in a week or so. Try not to pick or scratch the scab to prevent infection.
- Wash your skin with soap and water a few times a day until it feels better. Pat dry.
- Place an ice pack or a cold cloth on the bite for about 15-20 minutes, a few times.
- If you have a severe reaction (a lot of swelling), go to the closest Emergency Department. You can take an over-the-counter antihistamine and call your health care provider.
- If you think a poisonous spider, bit you, (black widow spider or brown recluse spider), wash the area with soap and water and apply ice. You’ll need medical care right away. Go to the closest Emergency Department.
You can lessen the chance of being bitten by a spider by avoiding them. Learn about where they live and what poisonous spiders look like. Insect repellents with DEET or Picaridin are also very effective.
Bites from mosquitoes are itchy rather than painful. They look like a very small puffy white bump that usually shows up soon after the mosquito bites the skin and feeds on blood. The puffiness is swelling that is caused from inflammation.
- Most of the time mosquito bites heal on their own without any medical treatment.
- To prevent infection, wash the bite with soap and water and pat dry.
- Use an over-the-counter hydrocortisone cream or calamine lotion to the bite(s) if it’s very itchy.
- Avoid scratching the bite(s).
West Nile Virus (WN): West Nile virus is an illness that mostly affects birds. Humans and other animals can become infected if an infected mosquito bites them. Mosquitoes become infected by biting a bird that has the West Nile virus. According to the Center for Disease Control (CDC), the West Nile virus has been reported in 47 states and the District of Columbia. Outbreaks of the WN virus most often occur during the summer and fall in the United States. However, most people who become infected with the WN virus don’t get sick (8 out of 10). Symptoms are like the flu and usually go away without treatment but can be serious.
Eastern Equine Encephalitis virus (EEEV) is a rare but serious illness transmitted by an infected mosquito. It affects the brain in humans and can lead to permanent damage. Horses can also acquire EEE the same way humans get it According to the Center for Disease Control there were 38 confirmed cases are reported in the United States in 2019, a number that has quadrupled since 2014. People who live in areas where EEE has been reported (Florida, Georgia, Massachusetts, and New Jersey), and who spend a lot of time outdoors in these areas are at the greatest risk. Adults over 50 years of age as well as teens and children under the age of 15, are at greatest risk of severe disease (and complications) after becoming infected with the EEE virus. Symptoms include fever, headache, restlessness, sleepiness, no appetite, vomiting, diarrhea, and in very bad cases, convulsions and coma.
Malaria: Malaria is a very serious illness and major cause of death in certain areas of the world. Although it’s not found in the United States, you’re at risk if you live or travel to certain countries, especially in sub-Saharan Africa and South Asia. Mosquitoes become infected with one of four different types of parasites then spread it to humans when they bite. Symptoms include; chills, fever, vomiting, diarrhea, headache, and yellowing of the skin and eyes. If you are traveling to areas that are known to have malaria outbreaks, tell your health care provider. You can take medicine that will lessen your chance of getting malaria while you travel. No matter what, avoid mosquitoes; wear long sleeves/pants; and wear DEET insect repellant.
Yellow fever: Yellow fever is a very serious illness caused by the bite of an infected mosquito. You’re at risk if you live or travel to regions such as South Africa. Not every mosquito carries yellow fever. If an infected one bites you, symptoms usually start 3-6 days later. Early symptoms include headache, muscle and joint aches, fever, flushing and loss of appetite. Most of the time people get better within about 3-4 days. Those who don’t may have severe symptoms such as: an irregular heartbeat, bleeding and eventually, coma.
Zika virus is usually caused by the bite of certain infected mosquitos called “Aedes aegypti and Aedes albopictus.” The Zika virus is usually mild and people rarely die of it. Only about 1 in 5 people who are infected with the Zika virus will actually get sick; however, infants born to mothers who are infected are at risk of having a serious birth defect called “microcephaly” or small head. The Center for Disease Control (CDC) recommends women (who are sexually active and not using a reliable method of birth control as well as women who are trying to become pregnant), should talk to their health care provider before traveling to areas known to be infected by the Zika virus. Anyone traveling to areas affected by the Zika virus should use methods to avoid mosquito bites. Zika virus can be spread by sexual contact. Ask your sexual partner(s) if they have traveled to an area affected by the Zika virus. Talk to your health care provider to find out if you are at risk and avoid having sex or use condoms every time you are sexually active. At this time there is no vaccine to prevent Zika virus.
Chikungunya: Chikungunya is another virus transmitted to people by infected mosquitos. Within the last few years, the Chikungunya virus has been active in the Caribbean and over 40 countries including Asia, Africa, and Europe. Although the virus is uncommon in the United States, there have been many reported cases in Puerto Rico and the U.S. Virgin Islands. Symptoms include fever and joint pain and usually appear within 3 to 7 days after being bitten by an infected mosquito. There is no vaccine to prevent Chikungunya. The best way to avoid the virus is prevention. Be prepared before traveling to areas where Chikungunya and other mosquito borne illnesses exist.
Dengue: Dengue is a worldwide health problem. The mosquito that bites and infects people with Dengue carries 1of 4 similar viruses. Symptoms usually include a high fever and two other symptoms such as stomach pain, vomiting, red spots on skin, bleeding from the gums/mouth or nose, black stools, fatigue, pale/cold skin and trouble breathing. The virus is rare in the United States yet it is common in areas where the infected mosquitos exist (Puerto Rico, Latin America, Southeast Asia and the Pacific Islands). There is no specific treatment aside from treating the fever, rest, drinking plenty of fluids, and eating a healthy diet and there is no vaccine to prevent Dengue at this time. Your best bet is to prevent mosquito bites especially while traveling in known areas of Dengue outbreaks.
Tick bites are most common if you’ve been around a wooded area. If you or someone you know are bit by a tick (and it’s still attached to your skin), use the tips listed below to lessen the chance of infection. If you remove a tick within 36 hours after it becomes attached (based on exposure to ticks) and the tick is not engorged, the tick is less likely to cause Lyme disease.
- Use tweezers to grab the tick at its head or mouth.
- Pull on the tick until it lets go. Do NOT twist it.
- Wash area with soap and water.
- Apply antibiotic ointment to the area.
- NEVER use petroleum jelly or a lit match to remove tick(s).
- Call your health care provider
- Save the tick and bring it to your appointment. (You can put the tick in small plastic bag or jar).
- If you are unable to pull the tick out of your skin, see your health care provider.
Lyme disease: Lyme disease is an infection that is caused from an infected deer tick. The deer tick is very small – about the size of a small freckle. Lyme disease occurs mostly in the Northeast, upper Midwest, and Pacific coast areas in the United States. Only infected deer ticks that attach to the skin can cause Lyme disease. The longer the tick stays attached, the more likely it will infect the person. If you develop Lyme disease, you might see a red bump that spreads into a rash that often looks like a “bulls eye” (pink in the center and darker red on the outside). Symptoms of Lyme disease are similar to the flu. Early symptoms may also include chills, fever, headache, body aches, and tiredness. Later symptoms can include swollen joints and general weakness. Bottom line; if you think a deer tick has bitten you, call your health care provider.
