The disease can spread from wild rodents to pets and people. Over the past 10 years, as few as 1 and as many as 17 cases of plague were reported in the United States, according to the CDC , most in the rural West. Symptoms of plague include swollen lymph nodes, headache, fever, and chills that appear from one to six days after the bite.
Beestings cause a sharp pain that may continue for a few minutes, then fade to a dull, aching feeling. The area may still feel sore to the touch a few days later. A red skin bump with white around it may appear around the site of the sting, and the area may itch and feel hot to the touch. If you've been stung by a bee before, your body may also have an immune response to the venom in the sting, resulting in swelling where the sting occurred or in an entire area of your body, including your throat and lungs.
If you have this type of allergic response, called anaphylaxis , it is a medical emergency that needs treatment immediately. Symptoms of a severe allergy to a beesting include hives, swelling, trouble breathing, dizziness, cramps, nausea, diarrhea, and even cardiac arrest. Lice bites are tiny red spots on the shoulders, neck, and scalp from small parasitic insects that can live on your clothes or in your bedding.
Some people may develop a larger, uncomfortable skin rash from lice bites. Continual scratching of the itchy spots could lead to an infection, marked by symptoms including swollen lymph nodes and tender, red skin. An infected lice bite may also ooze and crust over; it will need to be treated by a doctor, but lice are not known to carry other diseases.
Ant bites and stings are typically painful and cause red skin bumps. Some types of ants, like fire ants, are venomous, and their bites can cause a severe allergic reaction.
Fire ants bite first to hold on and then sting, giving a sharp pain and a burning sensation. If you're bitten by fire ants , you may see white, fluid-filled pustules or blisters pictured a day or two after the sting. These last three to eight days and may cause scars. The bumps may also be itchy and red, and you may have swelling around the site. It's important not to scratch or break open the blisters because they can become infected, notes the American College of Allergy, Asthma, and Immunology.
Carpenter ant bites are also painful because they spray formic acid into the bite, which causes a burning feeling. Mites do not usually spread disease, but their bites can irritate the skin and cause intense itching. Itch mites usually feed on insects but will bite other animals, including people. The bites usually go unnoticed until itchy, red marks develop that may look like a skin rash. Chiggers are a form of mite that inject their saliva so that they can liquefy and eat skin. In response to a chigger bite , the skin around the bite hardens.
The surrounding skin becomes irritated and inflamed pictured , and an itchy red welt develops. Mites also cause the condition called scabies , which is contagious from person to person, notes the CDC. Female scabies mites burrow into the skin to lay eggs. When the eggs hatch, the larvae come to the skin's surface.
They begin to molt and then burrow back into the skin to feed. This results in a skin rash that may look like acne pimples and create intense itching that gets worse at night. You may also notice light, thin lines on the skin where the mites have burrowed, including between the fingers, in the bends at the wrists and knees, and under jewelry on the wrists and fingers.
Kissing bugs, also known as assassin bugs, can pass on the parasites that cause Chagas disease. According to research from the University of Texas at El Paso published in October in the journal Acta Tropica , more than half of these insects carry the parasite.
Kissing bugs hide in the daytime but emerge at night, often leaving bites on the face and causing a swollen eyelid. In the first few weeks after infection, symptoms of Chagas disease can include fever, fatigue, body aches, headache, rash, a loss of appetite, diarrhea, and vomiting. But, the CDC notes , in the long term, and even decades later, about 30 percent of people infected by kissing bugs will develop serious complications of Chagas disease: an enlarged heart, heart failure , abnormal heart rhythm, cardiac arrest, or an enlarged colon, also known as megacolon.
Hornet stings like bee and wasp stings are usually painful, itchy, red, and swollen immediately after they happen, without causing long-term effects.
Many people can simply ice the area to soothe pain and pop an over-the-counter antihistamine like Benadryl to help with itching. Symptoms typically disappear after a day or two, says the Mayo Clinic. Call and seek emergency medical treatment if you experience any of these symptoms. Hornets typically build their large paper nests in tree hollows, as well as undisturbed spots in barns, attics, and even walls, according to information from the University of Kentucky.
Hornets will defend their nests and may attack you if you get too close, so leave the area if you do come across one.
If you come across a solitary hornet, leave it alone; hornets typically only sting when threatened, the University of Kentucky notes. And if you do get stung, leave the area right away to avoid another attack, Russell says. According to the University of Kentucky , these flies can both target humans who are outside, and the intensity of their attack varies from year to year. Bites can be painful and cause bleeding, swelling, irritation, or an allergic reaction. Here's how to recognize, treat, and prevent yellow jacket stings.
